拇指基底关节置换术（Touch）
在骨关节炎性拇指基底（Touch植入物）双活动度全关节置换术后，分阶段康复计划：初期使用拇指夹板保护新关节，随后恢复对掌功能与活动度，最后逐步增强捏力与握力。
本方案指导您在拇指基底关节置换术（一种双活动度全关节置换术，采用Touch假体）后的康复过程，该手术用于治疗拇指基底关节炎，由基兰·希尔帕拉（Kieran Hirpara）医生在罗克汉普顿 Mater 私人医院实施。方案从您的家庭锻炼计划开始，随后是专为您的手部治疗师编写的结构化临床方案；请在首次治疗时携带此页面或其PDF文件，以确保您的康复过程协调一致。您的手部治疗师可能会根据您的康复进展调整计划。您的全部康复过程均通过正式的手部治疗进行指导。
如果您在术后对伤口有任何担忧，请联系诊所。拍摄伤口照片并通过电子邮件发送以供审查通常很有帮助。
预期情况¶
拇指基底的关节（即大多角骨-掌骨关节，或称 CMC 关节）是拇指与手腕相接之处，也是骨关节炎非常常见的发病部位。在该手术中，磨损的关节面被切除并替换为小型人工关节：双活动假体，这是一种带有额外活动表面的微型球窝关节，使其稳定且运动平滑。大多角骨得以保留，拇指长度得以维持，因此恢复期通常短于大多角骨切除术（一种较旧的手术方式，需切除骨骼并依赖瘢痕组织在数月内形成）。
植入物位置良好时，其稳定性高且能立即分担负荷，因此拇指只需短期保护，而非数周固定。计划是让软组织愈合，随后尽快恢复拇指对指（触碰手指）功能及活动，继而增强肌力。
恢复过程分为三个阶段：
- 首先，保护（约前 2–3 周）。 前一周左右使用松软厚敷料，随后使用拇指夹板以让新关节休息，同时使伤口和软组织愈合。在此期间，手指、手腕及手部其余部分保持活动。
- 其次，活动（约第 2–3 周至 6 周）。 去除日间夹板后，开始进行轻柔的主动活动（对指、抬起拇指、张开虎口及环绕运动），并用手进行轻度的日常任务。
- 最后，强化（6 周以后）。 一旦植入物与骨骼结合，开始进行捏力和握力强化，并逐步增加强度。肌力在接下来的 6 至 12 个月内持续改善。
早期需注意的一点是，如果在新关节周围组织愈合前将其强行置于极端位置，新关节可能会脱位。这种情况并不常见，早期计划的核心原则仅是避免在软组织愈合过程中强行活动拇指。
注意事项与限制¶
- 请按照指示佩戴拇指夹板（前2–3周佩戴日间夹板，之后佩戴夜间夹板直至6周），并在手部治疗师允许前持续佩戴夹板以提供保护。
- 切勿将拇指强行置于极端位置，并在最初几周内避免突然或不自然的抓握动作；在新关节稳定之前，过度用力可能导致脱位。仅在舒适范围内活动。
- 在约6周内，切勿进行任何用力的捏、握、扭转（如拧瓶盖、使用钥匙、开关水龙头）或提举动作；强化训练仅在手部治疗师开始指导后进行。
- 从一开始就要保持手指、手腕及手部其余部分的活动，并在早期抬高患肢以减轻肿胀。
- 当您佩戴日间夹板，或无法舒适且无痛地握住方向盘时，切勿驾驶车辆。
有关伤口、肿胀和瘢痕管理，请参阅诊所的伤口护理指南。
您的练习¶
这些是您讲义中的练习。仅在 Hirpara 医生和您的手部治疗师的指导下开始练习，并严格遵循您被允许的活动范围和限制。早期练习（对指、拇指上抬、侧向运动、虎口拉伸和轻柔画圈）旨在恢复拇指活动度，同时不使新关节承受负荷，这些练习在您停用日间夹板后即可开始。橡皮泥和对掌捏力是后期的强化练习，应在约六周后、由您的手部治疗师指导时才开始。在早期几周，请保持所有动作轻柔且不勉强，如果拇指根部出现尖锐疼痛，请立即停止相关动作。
您的临床方案¶
本页面其余部分为双活动度大多角骨-掌骨关节（Touch）全关节置换术后的分阶段康复临床方案。本节内容将提供给您的手治疗师，每个阶段均以通俗易懂的语言解释当前的康复重点。与大多角骨切除术不同，该植入物即刻稳定且承担负荷，因此固定时间极短，早期即可恢复主动对掌功能；植入物特有的早期风险是若强行活动至极限范围可能导致脱位，因此前几周需在保护免受强制/极限位置活动的同时恢复关节活动度，待骨整合完成后逐步进展至负重强化训练。
治疗前，请查阅患者的手术记录和既往病史，并与主刀医生沟通植入物的就位/稳定性及术中任何注意事项。Hirpara 医生的方案为：术后 7–10 天使用软性厚敷料，随后佩戴拇指人字夹板（thumb spica）白天支具 2–3 周，之后继续佩戴夜间支具至术后 6 周（腕关节中立位，拇指处于掌侧中间外展位，指间关节自由活动）。大多角骨予以保留，拇指长度得以维持。
第一阶段 — 保护（第0周至约2–3周）¶
最初几周旨在使软组织稳定并保护新关节。拇指置于软性厚敷料中，随后佩戴拇指人字夹板日间支具，同时手指、手腕及手部其余部分保持活动。禁止进行拇指抗阻训练，禁止使拇指处于强迫或极端位置（早期脱位是植入物特有的风险）。
致您的手部治疗师：
教育与注意事项 - 固定拇指基底：软性厚敷料7–10天 → 拇指人字夹板日间支具佩戴约2–3周（腕关节中立位，拇指处于掌侧中间外展位，指间关节自由活动） - 避免强迫/极端拇指位置及突然抓握：早期脱位是植入物特有的风险 - 禁止拇指抗阻训练（禁止捏、握、扭转或提举） - 保持植入物无负荷；仅进行轻度的无负荷手部活动
管理 - 伤口：按医嘱进行外科敷料处理；监测感染迹象 - 水肿：抬高患肢，轻柔的手部泵动练习，必要时冰敷 - 锻炼：拇指指间关节、手指及腕关节的主动活动范围（ROM）练习；保持全手活动度；暂不进行主动掌指/腕掌关节活动或对掌训练，禁止负荷
进展标准 - 伤口愈合稳定；患者感觉舒适；约2–3周后脱离日间支具进行主动活动
第二阶段 — 夜间夹板下主动活动（约第2–3周至第6周）¶
约在术后2至3周时，日间夹板拆除，开始轻柔的拇指主动活动：对掌（Kapandji分级进展）、掌侧及桡侧外展、轻柔的环转运动及虎口活动度训练。夜间夹板继续佩戴至术后6周。鼓励进行轻度的日常手部使用；但仍需避免用力握持和捏持。
致您的手治疗师：
评估 - 拇指主动对掌（Kapandji评分）、掌侧/桡侧外展、虎口宽度；疼痛与肿胀情况；伤口/瘢痕复查
教育与注意事项 - 拆除日间夹板；继续佩戴夜间夹板至术后6周 - 仅进行无阻力拇指主动活动：术后6周内禁止用力握持或捏持 - 活动范围以舒适为限；避免强行达到终末活动度
管理 - 练习：主动无阻力对掌（Kapandji分级进展）、掌侧及桡侧外展、轻柔环转运动、虎口活动度训练；手部轻度日常功能使用；伤口愈合后开始瘢痕按摩
进阶标准 - 主动对掌功能良好恢复；伤口愈合；约术后6周时无阻力活动无痛
第三阶段——负荷与强化（第6周起）¶
约6周时，植入物已实现骨整合，可开始负荷。开始进行捏力和握力强化训练（包括橡皮泥捏力、钥匙状捏力、指尖捏力及对掌强化），并逐步增加强度。力量在接下来的6至12个月内持续成熟。
致您的手治疗师：
评估 - 与对侧相比的关键/指尖捏力及握力；对掌功能；负荷下的疼痛/肿胀反应；根据需要进行功能性和工作特异性测试
教育与注意事项 - 从第6周开始渐进性捏力和握力强化；逐步增加负荷 - 预期力量在6–12个月内成熟；告知患者对较重负荷需保持耐心
管理 - 练习：橡皮泥捏力、钥匙状/指尖捏力、对掌强化、渐进性抗阻训练；握力强化；继续进行任何残留的活动度训练和瘢痕处理 - 一旦力量达到功能水平且功能恢复良好，可考虑出院 - 如果恢复出现平台期或结果不佳，考虑转诊回主治医生
出院标准 - 功能性、接近对称的捏力和握力；日常及工作特异性使用时无痛
恢复工作与活动¶
早期即可在舒适范围内鼓励进行日常轻度手部活动（如进食、书写、轻度自理），前提是避免强行活动拇指或进行用力的捏握和抓握。由于佩戴日间夹板期间或无法舒适抓握方向盘时不得驾驶，因此在前几周需安排交通协助。通常在脱离日间夹板且能无痛抓握方向盘后即可恢复驾驶，一般在术后两至四周，经Hirpara医生确认。
办公室工作及轻度工作通常在两至四周内即可恢复；体力劳动及较重工作需等待至约六周，随后逐步增加负荷，因为强力捏握和抓握负荷仅在六周后开始。力量持续改善期为6至12个月，因此较重及更具挑战性的任务应逐步恢复，而非一次性回归，具体取决于拇指的反应情况，并由Hirpara医生及您的手部治疗师综合评估，而非仅依据日历时间。
术后方案¶
本方案与诊所的一般康复建议并行；请参阅术后疼痛管理、伤口护理和疤痕管理。上述分阶段计划反映了双活动度拇指基底关节置换术后的康复指南，您的持续康复将由Hirpara医生和您的手部治疗师根据您的拇指恢复情况个体化指导。

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¶
- 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.
- 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.
- 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.
- 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.
- 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.
