Isang kabuuang pagpapalit ng balikat: isang metal na bola ay nakapirmi sa buto ng itaas na braso at isang plastik na socket ay nakapirmi sa balikat — muling nililikha ang natural na hugis ng bola at socket. Kieran Hirpara 4.0

Bakit inirerekomenda ang operasyong ito

Ang total shoulder arthroplasty, kilala rin bilang joint replacement, ay isang operasyon upang ayusin ang sira o siraang shoulder joint. Maaaring inirekomenda ito ng iyong surgeon dahil mayroon kang wear-and-tear arthritis o instability na hindi gumaling sa mga non-surgical na gamutan tulad ng physical therapy. Karamihan sa mga pasyenteng may ganitong problema ay nakakakita ng patuloy na pagpapabuti sa kanilang function at pagbawas ng sakit pagkatapos ng operasyon.

Karaniwang inaalok ang operasyong ito sa mga pasyenteng nangangailangan ng mas mahusay na stability at range of motion. Bagaman magkapareho ang mga resulta para sa mga lalaki at babae, maaaring isaalang-alang ng iyong surgeon ang iyong edad at tiyak na mga salik ng iyong shoulder habang inirerekomenda ang uri ng replacement. Ang pangunahing layunin ay bawasan ang sakit at ibalik ang kakayahang gumalaw nang malaya ang iyong braso.

Bago ang operasyon

Kailangan mong mag-fasting bago ang iyong operasyon at itigil ang pag-inom ng ilang gamot ayon sa utos ng iyong surgeon. Mangyaring mag-arrange ng isang tiwala kang tao na dadalhin ka pauwi at magsuot ng komportableng damit sa araw ng operasyon. Maaaring mag-order ang iyong surgeon ng mga X-ray, MRI scans, blood tests, o pagsusuri ng anestesia bago ito. Ang mga pagsusuring ito ay tumutulong sa iyong medical team na maunawaan ang kalidad ng iyong buto at pangkalahatang kalusugan upang maayos ang iyong paggamot nang ligtas. Dala mo ang kumpletong listahan ng lahat ng kasalukuyang gamot sa iyong appointment. Ang paghahanda na ito ay siguraduhing handa ka para sa iyong single incision surgery at sumusuporta sa isang maayos na paggaling.

Sa araw ng operasyon

Dadating ka sa ospital at makikilala mo ang iyong anestesista bago ang operasyon. Ang operasyong ito ay ginagawa sa ilalim ng pangkalahatang anestesia na pinagsama ng regional nerve block. Ikaw ay lubos na matutulog sa panahon ng operasyon, at ang block (isang injeksyon na nagpapabango sa mga nerbiyong nagpapadala ng sensasyon sa braso bago ka gumising) ay nagbibigay ng pagpapagaan ng sakit sa unang 12 hanggang 24 oras pagkatapos ng operasyon. Ang iyong anestesista ay makikita ka bago ang operasyon at ipaliwanag ang parehong bahagi.

Ang iyong surgeon ay gagawa ng proseso sa pamamagitan ng isang bukas na hiwa sa iyong balikat. Pagkatapos, lilipat ka sa recovery area upang gumising nang ligtas. Karamihan sa mga pasyente ay nakakaramdam na ang mga unang oras ay madaling hawakan sa tulong ng nerve block. Mananatili ka sa recovery hanggang sa kumpirmahin ng iyong team na ikaw ay stable at komportable.

Ang kinabibilangan ng operasyon

Gagawa ang iyong doktor ng isang hiwa sa harap ng iyong balikat upang ma-access ang kasukasuan. Ang ganitong bukas na paraan ay nagbibigay-daan sa direktang paggawa sa mga istruktura ng balikat. Sa loob, tinatanggal ng doktor ang mga nasirang ibabaw ng kasukasuan at pinapalitan ito ng mga bahaging gawa sa metal at plastik upang maibalik ang maayos na galaw. Kung mayroon kang napunit na rotator cuff, maaaring ayusin ito ng doktor sa pamamagitan ng pag-ikot ng sira na tendon pabalik sa buto gamit ang mga maliit na anchor.

I-secure ng doktor ang mga bagong bahagi ng kasukasuan sa iyong buto upang matiyak na mananatili ito sa lugar. Kapag na-set na ang pagpapalit, isasara ang hiwa gamit ang mga tahi. Maglalagay ang iyong doktor ng dressing upang protektahan ang lugar. Bagaman may mga opsyon na may robotic assistance, isinasagawa ang proseduryo na ito gamit ang mga pamantayang teknikal na pampagpulong. Ang tiyak na uri ng implant at paraan na pinili ay nakadepende sa kondisyon ng iyong balikat at sa pagtatasa ng iyong doktor.

Ang operasyong ito ay dinisenyo upang bawasan ang sakit at mapabuti ang paraan ng paggalaw ng iyong braso. Para sa ilang pasyente, maaaring gumamit ang doktor ng reverse total shoulder replacement, na nagbabago ng paraan ng pagtatrabaho ng kasukasuan kumpara sa isang karaniwang pagpapalit. Ang pagpili sa pagitan ng mga uri na ito ay nakadepende sa kung intact o napunit ang iyong rotator cuff. Pipili ang iyong doktor ng paraan na pinaka-angkop sa iyong mga pangangailangan.

Pagkatapos ng operasyon

Gising ka sa recovery ward kung saan pinamamahalaan ang iyong sakit gamit ang pangkalahatang gamot. Ang iyong balikat ay balutan ng dressing at suportado ng sling o brace. Hindi ka mag-iisa; may kailangang kasama ka sa loob ng unang 24 na oras. Karamihan sa mga pasyente ay nananatili ng isang gabi sa ospital pagkatapos ng operasyong ito, bagaman may mga makakapagpauwi sa araw ng operasyon. Ang iyong surgeon ay gumagamit ng isang bukas na incision sa lugar ng balikat. Ang maagang paggalaw ay ligtas at nakakatulong sa iyong paggaling. Magsisimula ka ng banayad na ehersisyo upang mapabuti ang iyong galaw at lakas.

Pagbawi

Sa unang ilang araw, mararamdaman mo ang pananakit at pamamaga sa paligid ng iyong balikat. Ito ay normal habang ang iyong katawan ay nagpapagaling mula sa bukas na hiwa na ginawa sa ibabaw ng kasu-kasuan. Gabay ng iyong doktor ang paggamit ng yelo at gamot upang mapagaan ang hindi komportableng pakiramdam na ito. Magdadala ka ng sling upang protektahan ang balikat habang ito ay nagse-settle.

Ang iyong pang-araw-araw na gawain ay magpupokus sa banayad na galaw at mga espesipikong ehersisyo na inirekomenda ng iyong pisyoterapeuta. Sisimulan mo ito sa mga simpleng galaw upang maibalik ang saklaw ng galaw habang iwasan ang mabibigat na pag-angat o biglaang paghila. Habang bumababa ang pamamaga, unti-unti mong dadagdagan ang iyong aktibidad. Inaasahan mong makabalik sa mga isport at libangan kapag ang iyong balikat ay naramdaman na itong matatag at malakas.

Ang pagbawi ay isang personal na paglalakbay. Maaaring magkaiba ang iyong timeline sa iba, at ang iyong doktor at pisyoterapeuta ang gabay sa iyo sa bawat hakbang upang matiyak ang pinakamahusay na resulta para sa iyong balikat.

Maaaring mangyari

Karamihan sa mga pasyente ay magaling, ngunit minsan ay maaaring magkaroon ng mga problema. Ang iyong surgeon at ang koponan ay mahigpit na susubaybayan ka upang maagang matukoy ang anumang isyu.

Kung mayroon kang nakaraang shoulder instability, maaaring mapansin mo na mas maganda ang pakiramdam ng iyong balikat sa paglipas ng panahon, ngunit maaari pa ring pakiramdam na medyo maluwag ito. Kung kailangan mo ng pangalawang operasyon upang ayusin ang nakaraang isyu, maaaring makaramdam ka ng pakiramdam ng pag-click o pagkagiling kung muling magiging unstable ang joint. Ito ay isang karaniwang hamon pagkatapos ng revision surgery.

Maaaring mapansin mo ang biglang pamamaga, pamumula, o init na kumakalat mula sa iyong sugat. Ang mga senyales na ito ay maaaring magpahiwatig na nagsisimula ang impeksyon. Kung makikita mo ang mga pagbabagong ito, tumawag agad sa iyong klinika. Huwag hintayin ang iyong susunod na appointment.

Kung makaramdam ka ng malalim, pulso-pulso na sakit na hindi bumababa sa simpleng gamot pang-alis ng sakit, o kung biglang magde-deform ang iyong balikat, maaaring mayroon kang fracture. Mas malaki ang tsansang mangyari ito kung higit sa 90 taong gulang ka o kung nakatira ka sa isang lugar na may mataas na antas ng social deprivation. Pumunta agad sa emergency department kung mangyari ito.

May ilang pasyente na nakakaramdam ng biglang "pop" o pakiramdam na ang joint ay lumipat sa kanyang posisyon. Tinatawag itong dislokasyon. Kung mararanasan mo ito, kailangan mo ng urgent na medikal na atensyon upang ibalik ang balikat sa tamang posisyon.

Kung kumakain ka ng testosterone, maaaring mapansin mo ang mga senyales ng impeksyon o kailangan ng isa pang operasyon nang mas maaga kaysa inaasahan. Kung mahina ang iyong mga buto, maaaring magreseta ang iyong surgeon ng gamot upang makatulong na maiwasan ang pag-loosen ng implant. Kung walang gamot na ito, maaaring mag-loosen ang implant sa paglipas ng panahon.

Kung napakalakas ng iyong aktibidad at naglalaro ka ng mga sports na nagbibigay ng mataas na demand sa iyong balikat, maaaring mahirapan kang bumalik sa mga gawaing ito. Maaaring pakiramdam na pagod o masakit ang iyong balikat pagkatapos subukang magbigat.

Ang table ng mga komplikasyon sa pahinang ito ay naglalaman ng mga karaniwang rate kung gusto mo ng mga detalye.

Kailan tawagan ang aming klinika

Tawagan ang iyong doktor kung ikaw ay magkaroon ng lagnat, lumalalang pamumula o paglabas ng likido mula sa sugat, o biglaang matinding sakit. Pumunta agad sa emergency room kung may pamamaga sa binti, hirap sa paghinga, pagkawala ng pakiramdam, o kung hindi mo na makagalaw ang iyong braso. Ang mga senyales na ito ay nangangailangan ng agad na pagsusuri upang mapanatili ang iyong paggaling.
