Pagpapalit ng Kasukasuan sa Base ng Hinlalaki (Touch)

Isang staged recovery plan pagkatapos ng dual-mobility total joint replacement ng arthritic thumb base (ang Touch implant), na pinoprotektahan ang bagong joint sa isang thumb splint sa simula, pagkatapos ay ibabalik ang opposition at paggalaw, at pagkatapos ay bubuuin ang pinch at grip strength.

Ang pahinang ito ay isinalin ng makina at hindi pa nasusuri ng isang doktor. Ang bersyong Ingles ang siyang opisyal.

Ang protocol na ito ay nagsisilbing gabay sa iyong paggaling pagkatapos ng thumb base joint replacement (isang dual-mobility total joint replacement, ang Touch implant) para sa arthritis ng base ng hinlalaki, kasama si Dr Kieran Hirpara sa Mater Private Hospital Rockhampton. Nagsisimula ito sa iyong home exercise program, na sinusundan ng structured clinical protocol na isinulat para sa iyong hand therapist; dalhin ang pahinang ito o ang PDF nito sa iyong unang therapy visit upang manatiling coordinated ang iyong rehabilitasyon. Maaaring i-adjust ng iyong hand therapist ang plano depende sa pag-unlad ng iyong paggaling. Ang lahat ng iyong recovery ay ginagabayan sa pamamagitan ng formal hand therapy.

Kung mayroon kang anumang alalahanin tungkol sa iyong sugat pagkatapos ng operasyon, makipag-ugnayan sa mga rooms. Madalas na nakatutulong ang pagkuha ng larawan ng sugat at pag-email nito para masuri.

Ano ang dapat asahan

Ang kasukasuan sa base ng iyong hinlalaki (ang trapeziometacarpal, o CMC, joint) ay kung saan nagtatagpo ang hinlalaki at ang pulso, at ito ay isang napakakaraniwang lugar ng arthritis. Sa operasyong ito, ang mga gasgas na surface ng kasukasuan ay tinatanggal at pinapalitan ng isang maliit na artificial joint: isang dual-mobility implant, isang maliit na ball-and-socket na may extra moving surface na nagpapatatag at nagpapadulas dito. Pinapanatili ang trapezium bone at pinapanatili ang haba ng iyong hinlalaki, kaya ang recovery ay karaniwang mas mabilis kaysa sa trapeziectomy (ang lumang operasyon, na nagtatanggal ng buto at umaasa sa pagbuo ng scar tissue sa loob ng maraming buwan).

Ang isang implant na maayos ang pagkakalagay ay matatag at kayang humati ng load agad-agad, kaya naman ang hinlalaki ay kailangan lamang protektahan sa loob ng maikling panahon sa halip na i-immobilize ng ilang linggo. Ang plano ay hayaang kumalma ang mga soft tissue, pagkatapos ay mabilis na ibalik ang opposition ng iyong hinlalaki (paghipo sa mga daliri) at paggalaw nito, at pagkatapos ay palakasin ito.

Ang recovery ay nahahati sa tatlong yugto:

  • Una, protektahan (mga unang 2–3 linggo). Isang malambot at makapal na dressing para sa unang linggo o higit pa, pagkatapos ay isang thumb splint upang ipahinga ang bagong kasukasuan habang kumakalma ang sugat at mga soft tissue. Panatilihing gumagalaw ang iyong mga daliri, pulso, at ang natitirang bahagi ng kamay.
  • Pagkatapos, igalaw (mula mga 2–3 hanggang 6 na linggo). Pagkatapos tanggalin ang day splint, magsisimula ka ng banayad na active movement (opposition, pag-angat ng hinlalaki, pagbubukas ng web space at pag-ikot) at gamitin ang kamay para sa mga magagaan na pang-araw-araw na gawain.
  • Pagkatapos, palakasin (mula 6 na linggo pataas). Kapag ang implant ay nakakabit na sa buto, magsisimula ang pinch and grip strengthening at unti-unting palalakasin. Ang lakas ay patuloy na mag-i-improve sa sumunod na 6 hanggang 12 buwan.

Ang isang bagay na dapat isaalang-alang sa simula ay maaaring ma-dislocate ang bagong kasukasuan kung mapipilit ito sa isang extreme position bago pa gumaling ang mga tissue sa paligid nito. Hindi ito karaniwan, at ang maagang plano ay binuo lamang upang hindi pilitin ang hinlalaki habang ito ay kumakalma.

Mga pag-iingat at limitasyon

  • Isuot ang iyong thumb splint ayon sa itinuro (day splint para sa unang 2–3 linggo, pagkatapos ay night splint hanggang 6 na linggo) at panatilihing nakasuot ang splint para sa proteksyon hanggang sa payagan ka na ng iyong hand therapist.
  • HUWAG piliting ilagay ang hinlalaki sa mga extreme position, at iwasan ang bigla o awkward na paghawak sa mga unang linggo; ang bagong joint ay maaaring ma-dislocate kung itutulak nang masyadong malayo bago ito maging stable. Gumalaw lamang sa abot ng iyong komportableng nararamdaman.
  • HUWAG gumawa ng anumang malakas na pag-pinch, pagkapit, pagpihit (takip ng garapon, susi, gripo) o pagbuhat hanggang sa humigit-kumulang 6 na linggo; ang strengthening ay magsisimula lamang kapag sinimulan na ito ng iyong hand therapist.
  • Panatilihing gumagalaw ang iyong mga daliri, pulso at ang natitirang bahagi ng kamay mula sa simula, at panatilihing naka-elevate ang iyong kamay sa umpisa upang mabawasan ang pamamaga.
  • HUWAG magmaneho hanggang sa humigit-kumulang apat hanggang anim na linggo, kapag wala ka na sa iyong splint at kaya mo nang hawakan ang manibela nang komportable at walang sakit.

Iyong mga ehersisyo

Idikit ang dulo ng hinlalaki sa base ng bawat daliri nang sunod-sunod, simula sa hintuturo pababa patungo sa kalingkingan.

Kieran Hirpara 4.0

Thumb opposition (Kapandji ladder)

Dahan-dahang idikit ang dulo ng iyong hinlalaki sa gilid ng iyong hintuturo, pagkatapos ay sa dulo ng bawat daliri nang sunod-sunod, at pagkatapos ay i-slide ito pababa sa kalingkingan patungo sa base nito — ituloy ang pag-akyat sa 'hagdan' nang kaunti habang lumuluwag ang pakiramdam. Gumalaw lamang hanggang sa kung ano ang komportable. Ito ang pangunahing galaw upang maka-recover pagkatapos ng thumb base replacement, at sinisimulan ito nang dahan-dahan kapag wala ka na sa iyong day splint (humigit-kumulang dalawa hanggang tatlong linggo).

Gawin ang ladder 5–10 beses, 2–3 beses sa isang araw, hanggang sa kung ano ang komportable

Habang nakaharap pataas ang palad, itaas ang hinlalaki nang diretso palayo sa patag na palad patungo sa kisame.

Kieran Hirpara 4.0

Palmar abduction (iangat ang hinlalaki mula sa palad)

Ipatong ang iyong kamay nang patag, nakaharap ang palad sa itaas. Habang pinapanatiling tuwid ang iyong hinlalaki, iangat ito palayo sa iyong palad patungo sa kisame, na tila binubuksan ang iyong kamay upang humawak ng lata — pagkatapos ay ibaba itong muli. Binubuksan nito ang web space at ibinabalik ang reach ng hinlalaki. Panatilihin itong banayad at hindi pinipilit; huwag itulak hanggang sa dulo ng paggalaw sa mga unang linggo.

10 beses, 2–3 beses sa isang araw, hanggang sa komportable

Habang ang palad ay nakaharap sa sahig, igalaw ang hinlalaki nang patagilid palayo sa hintuturo sa plane ng palad.

Kieran Hirpara 4.0

Radial abduction (paglayo ng hinlalaki sa gilid)

Ipatong ang iyong kamay nang patag na nakaharap sa ibaba ang palad. I-slide ang iyong hinlalaki nang patagilid, palayo sa iyong hintuturo, habang pinapanatili ito sa parehong patag na plane ng iyong palad — gaya ng pagbuo ng hugis 'L' — pagkatapos ay ibalik ito. Ibinabalik nito ang sideways reach ng hinlalaki. Gumalaw nang mabagal at huminto bago makaramdam ng anumang strain.

10 beses, 2–3 beses sa isang araw, hanggang sa komportable

Dahan-dahang pagbubukas ng malambot na web ng balat sa pagitan ng hinlalaki at hintuturo upang mapanatili itong supple.

Kieran Hirpara 4.0

Stretch ng web-space

Buksan ang espasyo sa pagitan ng iyong hinlalaki at hintuturo nang kasinglawak ng komportable, habang nararamdaman ang banayad na stretch sa web space. Maaari mong ipatong ang iyong kamay sa mesa at hayaang dahan-dahang bumukas ang hinlalaki, o itupi ito sa paligid ng isang bilog na bagay. Panatilihin ang bukás na posisyon nang sandali, pagkatapos ay i-relax. Pinapanatili nito na hindi humigpit ang web space habang ikaw ay gumagaling — panatilihin itong banayad, huwag kailanman pilitin.

Hawakan ng ~5 segundo, 5–10 beses, 2–3 beses sa isang araw

Pagguhit ng mabagal at swabeng mga bilog gamit ang hinlalaki upang gumalaw ito sa buong range nito.

Kieran Hirpara 4.0

Circumduction ng hinlalaki

Habang nakarelaks ang iyong kamay, gumuhit ng mabagal at swabeng mga bilog gamit ang iyong hinlalaki, dahan-dahang igalaw ito sa buong range nito sa parehong direksyon — na tila naghahalo sa isang maliit na palayok. Panatilihing madali ang mga bilog at nasa loob ng iyong comfort level. Ibinabalik nito ang pinagsamang rolling movement ng bagong joint at sinisimulan nang dahan-dahan kapag wala ka na sa day splint.

5–10 na ikot sa bawat direksyon, 2–3 beses sa isang araw

Pag-ipit ng therapy putty sa pagitan ng hinlalaki at gilid ng hintuturo, at pagdiin ng dulo ng hinlalaki sa mga dulo ng daliri.

Kieran Hirpara 4.0

Putty / key pinch (mula linggo 6)

Isang ehersisyo sa PAGHULING bahagi — mula sa ika-anim na linggo lamang, kapag nagsimula na ang iyong hand therapist sa strengthening. Pumitpit ng isang piraso ng therapy putty sa pagitan ng iyong hinlalaki at sa gilid ng iyong hintuturo (isang 'key' pinch), at ipitpit ang dulo ng iyong hinlalaki sa mga dulo ng iyong daliri (isang 'tip' pinch), unti-unting dagdagan ang puwersa sa mga susunod na linggo at buwan. HUWAG gumawa ng malakas na pagpipitpit o paghawak bago ang ika-anim na linggo — kailangan ng bagong joint ang panahong iyon upang kumalma at kumapit sa buto.

Ayon sa gabay ng iyong hand therapist (mula ~6 na linggo), unti-unting pagpapalakas

Ito ang mga ehersisyo mula sa iyong handout. Simulan lamang ang mga ito ayon sa gabay ni Dr Hirpara at ng iyong hand therapist, at manatili sa anumang range at limitasyong ibinigay sa iyo. Ang mga maagang ehersisyo (opposition, pag-angat ng hinlalaki, ang sideways movement, ang web-space stretch at gentle circles) ay nagbabalik ng paggalaw ng hinlalaki nang hindi binibigatan ang bagong joint, at sinisimulan kapag wala ka na sa iyong day splint. Ang putty at key pinch ay isang huling ehersisyo para sa pagpapalakas at hindi dapat simulan hanggang sa humigit-kumulang anim na linggo, kapag sinimulan na ito ng iyong hand therapist. Panatilihing gentle at hindi pilit ang bawat paggalaw sa mga unang linggo, at itigil ang anumang nagdudulot ng matalas na sakit sa base ng hinlalaki.

Ang iyong clinical protocol

Ang natitirang bahagi ng pahinang ito ay ang staged clinical protocol para sa rehabilitasyon pagkatapos ng isang dual-mobility trapeziometacarpal (Touch) total joint replacement. Ang seksyong ito ay ibibigay sa iyong hand therapist, at ang bawat phase ay nagsisimula sa isang paliwanag sa simpleng Ingles tungkol sa kung ano ang nangyayari. Hindi tulad ng trapeziectomy, ang implant ay agad na stable at load-sharing, kaya minimal ang immobilisation at maagang naibabalik ang active opposition; ang early risk na partikular sa implant ay dislocation kung mapipilit sa extreme range, kaya ang mga unang linggo ay proteksyon laban sa mga forced/end-range positions habang ibinabalik ang motion, pagkatapos ay magpapatuloy sa loaded strengthening kapag osseointegrated na.

Bago ang treatment, suriin ang operation report ng pasyente at ang past medical history, at makipag-ugnayan sa treating surgeon tungkol sa implant seating/stability at anumang intra-operative concerns. Ang regimen ni Dr Hirpara ay isang soft bulky dressing sa loob ng 7–10 araw, pagkatapos ay isang thumb spica DAY splint sa loob ng 2–3 linggo, na susundan ng isang NIGHT splint hanggang sa ika-6 na linggo (wrist neutral, thumb in mid palmar abduction, IP free). Ang trapezium ay pinanatili at ang haba ng thumb ay napanatili.

Phase I — proteksyon (linggo 0 hanggang ~2–3)

Ang unang ilang linggo ay para sa paghilom ng mga soft tissue at proteksyon ng bagong joint. Ang thumb ay nakapahinga sa isang soft bulky dressing, pagkatapos ay sa isang thumb spica day splint, habang ang mga daliri, wrist at ang natitirang bahagi ng kamay ay patuloy na iginagalaw. Walang resisted thumb work, at walang pilit o extreme na posisyon ng thumb (ang maagang dislocation ay ang implant-specific risk).

Para sa iyong hand therapist:

Edukasyon at mga pag-iingat - I-immobilise ang base ng thumb: soft bulky dressing 7–10 araw → thumb spica DAY splint sa loob ng ~2–3 linggo (wrist neutral, thumb sa mid palmar abduction, IP joint ay free) - Iwasan ang mga pilit/extreme na posisyon ng thumb at biglaang pagkapit: ang dislocation ay ang maagang implant-specific risk - Walang resisted thumb work (walang pinch, grip, pag-twist o pagbuhat) - Panatilihing unloaded ang implant; light unloaded hand use lamang

Pamamahala - Sugat: surgical dressings ayon sa itinuro; i-monitor para sa impeksyon - Oedema: elevation, gentle hand pump, ice kung kinakailangan - Mga ehersisyo: active ROM ng IP joint ng thumb, ng mga daliri, at ng wrist; panatilihin ang full-hand mobility; wala pang active CMC/opposition work, walang loading

Pamantayan para mag-progress - Paghilom ng sugat; komportable; pag-alis sa day splint sa loob ng humigit-kumulang 2–3 linggo para sa active motion

Phase II — active motion sa isang night splint (linggo ~2–3 hanggang 6)

Mula humigit-kumulang dalawa hanggang tatlong linggo, tatanggalin na ang day splint at magsisimula ang banayad na active thumb movement: opposition (isang Kapandji progression), palmar at radial abduction, banayad na circumduction at web-space mobilisation. Ang night splint ay ipagpapatuloy hanggang anim na linggo. Hinihikayat ang magaan na pang-araw-araw na paggamit; ang mabigat na grip at pinch ay ipinagbabawal pa rin.

Para sa iyong hand therapist:

Assessments - Active thumb opposition (Kapandji score), palmar/radial abduction, lapad ng web-space; sakit at pamamaga; pagsusuri ng sugat/peklat

Education and precautions - Wala na sa day splint; ituloy ang NIGHT splint hanggang 6 na linggo - Active unresisted thumb motion lamang: walang mabigat na grip o pinch bago ang 6 na linggo - Panatilihin ang paggalaw sa loob ng comfort level; iwasan ang pagpilit sa end-range

Management - Mga ehersisyo: active unresisted opposition (Kapandji progression), palmar at radial abduction, banayad na circumduction, web-space mobilisation; magaan na pang-araw-araw na functional use ng kamay; simulan ang scar massage kapag magaling na ang sugat

Criteria to progress - Naibalik ang maayos na active opposition; magaling na ang sugat; pain-free unresisted motion sa humigit-kumulang 6 na linggo

Phase III — paglalagay ng load at pagpapalakas (ika-6 na linggo pataas)

Mula sa humigit-kumulang anim na linggo, ang implant ay osseointegrated na at maaari nang lagyan ng load. Magsisimula ang pagpapalakas ng pinch at grip (putty pinch, key at tip pinch, opposition strengthening) at unti-unting itataas ang antas nito. Ang lakas ay patuloy na mag-ma-mature sa sumunod na 6 hanggang 12 buwan.

Para sa iyong hand therapist:

Mga Assessment - Key/tip pinch at grip strength kumpara sa kabilang panig; opposition; tugon ng sakit/pamamaga sa paglalagay ng load; functional at work-specific testing kung naaangkop

Edukasyon at mga pag-iingat - Simulan ang progressive pinch at grip strengthening mula ika-6 na linggo; unti-unting dagdagan ang load - Inaasahan na ang lakas ay mag-ma-mature sa loob ng 6–12 buwan; payuhan ng pasensya sa mas mabibigat na loading

Pamamahala - Mga ehersisyo: putty pinch, key/tip pinch, opposition strengthening, progressive resistance; grip strengthening; ipagpatuloy ang anumang residual mobility at scar work - Isaalang-alang ang discharge kapag ang lakas ay functional na at nakamit na ang angkop na pagbabalik ng function - Isaalang-alang ang referral pabalik sa treating doctor kung ang recovery ay nag-plateau o mayroong poor outcome

Mga kraytirya para sa discharge - Functional, near-symmetrical na pinch at grip; walang sakit sa pang-araw-araw at work-specific na paggamit

Pagbabalik sa trabaho at aktibidad

Hinihikayat ang magaan na pang-araw-araw na paggamit ng kamay (pagkain, pagsusulat, magaan na pag-aalaga sa sarili) sa loob ng limitasyon ng iyong komportableng pakiramdam mula sa simula, basta't hindi nito kinakasangkutan ng pagpuwersa sa hinlalaki o malakas na pag-pinch at pag-grip. Dahil hindi ka dapat magmaneho hangga't hindi ka pa natatanggal sa iyong splint at hindi pa komportableng nahahawakan ang manibela, magplano ng tulong sa transportasyon sa mga unang linggo. Ang pagmamaneho ay karaniwang nagpapatuloy sa loob ng apat hanggang anim na linggo, kapag kaya mo nang hawakan ang manibela nang walang sakit, gaya ng kumpirmasyon ni Dr Hirpara.

Ang trabaho sa opisina at magaan na gawain ay karaniwang posible sa loob ng dalawa hanggang apat na linggo; ang manual at mas mabigat na trabaho ay naghihintay hanggang mga anim na linggo at pagkatapos ay unti-unting dinadagdagan, dahil ang malakas na pinch at grip loading ay nagsisimula lamang sa ika-anim na linggo. Ang lakas ay patuloy na bumubuti sa loob ng 6 hanggang 12 buwan, kaya ang mas mabigat at mas mapanghamong mga gawain ay binabalikan nang progresibo sa halip na biglaan, batay sa kung paano tumutugon ang iyong hinlalaki, kasama si Dr Hirpara at ang iyong hand therapist sa halip na sa kalendaryo lamang.

Pagkatapos ng iyong protocol

Ang protocol na ito ay kasabay ng pangkalahatang payo sa paggaling ng klinika; tingnan ang pamamahala ng sakit pagkatapos ng operasyon, pag-aalaga ng sugat at pamamahala ng peklat. Ang phased plan sa itaas ay sumasalamin sa nailathalang gabay sa rehabilitasyon pagkatapos ng dual-mobility thumb base joint replacement, at ang iyong patuloy na paggaling ay ginagabayan nang indibidwal ni Dr Hirpara at ng iyong hand therapist ayon sa pag-unlad ng iyong hinlalaki.

Thumb Base Joint Replacement (Touch) — Procedure Outcomes & Post-operative Rehabilitation (Dual-mobility TMC/CMC Total Joint Arthroplasty)

Topic scope: post-operative rehabilitation after a dual-mobility total joint replacement of the trapeziometacarpal (thumb base / CMC) joint for advanced thumb base osteoarthritis — the Touch implant. Unlike trapeziectomy, the trapezium is retained and thumb length preserved, and a correctly seated dual-mobility implant is immediately stable and load-sharing. The rehab is therefore a minimal-immobilisation, early-motion pathway: protect briefly against the implant-specific early dislocation risk, restore opposition within the first month, then load.

Defining principle of the rehab here: a trapeziectomy relies on a scar/haematoma "spacer" forming where the bone was removed, which takes roughly 12 months to mature — so rehab is slow by necessity. A dual-mobility thumb base replacement instead provides an immediately stable, load-sharing artificial joint, so immobilisation can be minimal, opposition is restored within the first month, and recovery is faster than trapeziectomy. The dual-mobility cup specifically reduces the early dislocation risk that drove longer immobilisation with older single-mobility implants. The one deliberate early restraint is therefore avoidance of forced/extreme thumb positions (the implant-specific dislocation risk) for the first few weeks, after which loaded pinch/grip strengthening begins. This is a newer implant: the evidence base is short-to-mid-term and low-to-moderate level, and rehab regimens are under-reported and not standardised.


A. PROCEDURE OUTCOMES (dual-mobility Touch TMC arthroplasty)

Dual-mobility total joint replacement of the thumb base is a comparatively new alternative to trapeziectomy for advanced trapeziometacarpal osteoarthritis. Early- to mid-term series report high implant survival and good restoration of pinch and function, with the principal trade-off being a higher complication/revision profile than the well-established trapeziectomy — though the dual-mobility design improves on the dislocation rate of earlier single-mobility implants.

  • High short-to-mid-term implant survival and good function. A Touch-specific series reported 96% implant survival at 2 years with high key-pinch strength; the main adverse events were soft-tissue complications (de Quervain-type tenosynovitis, trigger digit) rather than implant failure [Herren 2023]. A 150-patient dual-mobility cohort similarly reports early normalisation of function. Moderate (case series / retrospective cohort).
  • Faster recovery than trapeziectomy because the joint is immediately stable. Because the implant is load-sharing from the outset, the thumb is only briefly immobilised, patients return to near-normal activity early, and formal therapy may not always be required — contrasting with the ~12-month maturation of a trapeziectomy spacer [Duerinckx & Verstreken 2022]. Moderate (narrative review / cohort).
  • Opposition and pinch/grip recover well. Using the MOOVIS dual-mobility implant, the Kapandji opposition score improved from 7 to 10 with improved pinch and grip [Dreant 2018]. Moderate (cohort).
  • The dual-mobility design reduces dislocation. The extra articulation lowers the early dislocation risk that limited older single-mobility prostheses, supporting earlier mobilisation [Tchurukdichian 2019; Martins 2020]. Moderate (cohort / mechanistic).
  • Lower reoperation than ball-and-socket designs; persistent revision risk overall. A network meta-analysis found dual-mobility implants had lower reoperation than ball-and-socket designs, with TOUCH reoperation around 1.0% [Burnett 2026 NMA]. Reported outcomes continue to evolve in ongoing reviews [Tosti & Duerinckx 2026]. Moderate (NMA of mostly observational data).
  • Registry-level work-absence benchmark. Swedish registry data give a sense of real-world recovery: sick leave of roughly 94 days for men and 109 days for women — a benchmark to set realistic return-to-work expectations rather than a target. Moderate (registry).

B. REHABILITATION / THERAPY EVIDENCE

The central rehab questions are (1) how long to immobilise, and (2) when to start motion and loading. Because the implant is immediately stable, the modern answer is minimal immobilisation with early active opposition — but the literature is explicit that there is no consensus and wide variation between centres, and that rehab protocols are under-reported.

  • Minimal immobilisation is justified by immediate stability. A correctly seated dual-mobility implant is stable and load-sharing, so prolonged casting is unnecessary; the thumb is briefly protected, then mobilised early, with opposition typically back within the first month [Duerinckx & Verstreken 2022]. Moderate (review).
  • No standardised regimen — wide variation in immobilisation and motion timing. A dedicated review of immobilisation and rehabilitation after thumb-base arthroplasty found reported immobilisation ranging from 2 to 12 weeks and active range-of-motion commencing anywhere from 1 to 6 weeks, with no consensus across studies [Barrett 2022]. This is the key caveat for any protocol: the timings are a defensible, surgeon-confirmed plan, not a trial-derived standard. Moderate (systematic review of heterogeneous protocols).
  • Early opposition recovery is achievable and is the functional priority. Improvement of the Kapandji opposition score (7→10) demonstrates that active opposition is the early rehab target and is realistically attainable in the first weeks-to-months [Dreant 2018]. Moderate (cohort).
  • The early restraint is dislocation avoidance, not protected healing. The dual-mobility design reduces but does not abolish early dislocation; the practical implication is to avoid forced/extreme thumb positions in the first weeks rather than to immobilise for prolonged periods [Tchurukdichian 2019; Martins 2020]. Moderate / mechanistic.

Recovery trajectory (expected, evidence-anchored)

Phase Window Restraint Hand use / therapy focus Strength / load Notes
I — Protect Week 0 to ~2–3 Soft bulky dressing 7–10 d → thumb spica DAY splint Keep IP/MCP/digits/wrist moving; oedema control; avoid forced/extreme thumb positions No resisted thumb work Early dislocation is the implant-specific risk; minimal immobilisation because the implant is immediately stable
II — Active motion Week ~2–3 to 6 NIGHT splint to 6 wk Out of day splint; active unresisted opposition (Kapandji), palmar + radial abduction, gentle circumduction, web-space work; light everyday use; scar massage once healed Still no heavy grip/pinch Opposition typically restored within the first month; faster than trapeziectomy
III — Load / strengthen Week 6+ Restrictions lifted Progress pinch/grip-specific loading and task use Pinch + grip strengthening from 6 wk (putty, key/tip pinch); full weight-bearing ~6 wk Strength matures over 6–12 months; return to heavy/manual work staged across this window

(Phase windows reflect KH-confirmed parameters and are consistent with the wide ranges reported in the literature; they are typical guides, not trial-derived deadlines — see Barrett 2022.)


C. KEY CONTROVERSIES / EVIDENCE QUALITY

  1. Replacement vs trapeziectomy. Dual-mobility replacement restores the joint and gives a faster functional return (immediate stability, opposition back within a month) versus the ~12-month maturation of a trapeziectomy spacer, but at the cost of a higher complication and revision rate and a shorter evidence track record. Trapeziectomy remains the well-established, lower-risk benchmark. Moderate; trade-off, not a clear winner.
  2. How long to immobilise / when to start motion. No consensus — reported immobilisation spans 2–12 weeks and AROM start 1–6 weeks [Barrett 2022]. This page's day-splint-2–3-weeks → night-splint-to-6-weeks → strengthen-from-6-weeks plan is a defensible, surgeon-confirmed regimen within that reported range, not a proven standard. Weak–moderate.
  3. Dislocation risk. The dual-mobility cup reduces the early dislocation that limited older single-mobility implants, but the risk is not zero in the first weeks — hence the early forced/extreme-position restraint [Tchurukdichian 2019; Martins 2020]. Moderate / mechanistic.
  4. Complication profile. Soft-tissue complications (de Quervain-type tenosynovitis, trigger digit) are the commonest early issues rather than implant failure [Herren 2023]; reoperation is low for dual-mobility (TOUCH ~1.0%) and lower than ball-and-socket designs [Burnett 2026 NMA]. Moderate.
  5. Maturity of the evidence. This is a newer implant: outcomes are short-to-mid-term, evidence is low-to-moderate level (case series, retrospective cohorts, registry and NMA of mostly observational data), and rehabilitation is under-reported and not standardised. Tone should be appropriately cautious. Evidence base still maturing.

D. EVIDENCE STRENGTH FLAGS (summary)

  • MODERATE (cohort / registry / NMA of observational data): high short-to-mid-term implant survival (96% at 2 yr, Touch) with good key-pinch; Kapandji opposition 7→10; dual-mobility lower reoperation than ball-and-socket (TOUCH ~1.0%); registry sick-leave benchmark (~94 d men / 109 d women); faster functional return than trapeziectomy.
  • MODERATE (systematic review of heterogeneous protocols): no consensus on rehab — immobilisation 2–12 weeks, AROM start 1–6 weeks (Barrett 2022).
  • WEAK / CONSENSUS: the specific immobilisation-then-early-opposition-then-strengthen phase timings (surgeon-confirmed, within the reported range; not trial-derived); the dislocation-avoidance rationale (mechanistic).
  • CAVEAT: newer implant — short-to-mid-term, low-to-moderate-level evidence; higher complication/revision rates than trapeziectomy persist; rehab under-reported.

Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and conditions that creators and other rights holders may use to share original works of authorship and other material subject to copyright and certain other rights specified in the public license below. The following considerations are for informational purposes only, are not exhaustive, and do not form part of our licenses.

Considerations for licensors: Our public licenses are intended for use by those authorized to give the public permission to use material in ways otherwise restricted by copyright and certain other rights. Our licenses are irrevocable. Licensors should read and understand the terms and conditions of the license they choose before applying it. Licensors should also secure all rights necessary before applying our licenses so that the public can reuse the material as expected. Licensors should clearly mark any material not subject to the license. This includes other CC- licensed material, or material used under an exception or limitation to copyright.

Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. If the licensor's permission is not necessary for any reason--for example, because of any applicable exception or limitation to copyright--then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable.

Creative Commons Attribution-NonCommercial 4.0 International Public License

By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution-NonCommercial 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.

d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.

e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.

f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.

g. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

h. Licensor means the individual(s) or entity(ies) granting rights under this Public License.

i. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation. For purposes of this Public License, the exchange of the Licensed Material for other material subject to Copyright and Similar Rights by digital file-sharing or similar means is NonCommercial provided there is no payment of monetary compensation in connection with the exchange.

j. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.

k. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.

l. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

b. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
