Isiqu se-femoral se-hip prosthesis esingenasimende

I-hip joint yakhiwe yi-socket, i-lining, i-ball head, isibambo nezinye izingxenye. Ingxenye ngayinye inezinto eziningana kanye nezincazelo. Izinto kanye nokukhethwa kwemodeli ngokuya ngokuhlinzwa okuhlukene kwe-hip. Kunezinhlobo ezimbili zeziqu: iziqu zesimende kanye neziqu ze-bio-joint. Isiqu sebhayoloji esisisebenzisayo njengamanje emhlabeni wonke siwumklamo omise okwe-wedge onezinhlangothi ezintathu, osetshenziselwa ukuthuthukisa ukudluliselwa kokucindezeleka nokuthuthukisa ukuzinza kwengxenye engemuva yesiqu. Umklamo we-stem end olungiselelwe kahle wandisa ukuzinza kwekhanda lebhola, futhi umklamo wentamo ocwebezelisiwe kakhulu uyacwengisiswa ukuze kuthuthukiswe ububanzi bokunyakaza kwe-prosthesis. I-proximal groove iqonde ngqo esiqondisweni sokuhanjiswa kokucindezeleka, okuhambisana nokuhlanganiswa okusheshayo kwe-osseo kanye nokuzinza okuhle kokuqala. Ubuso bomzimba we-stem bumbozwe ngokuphelele nge-plasma titanium slurry, futhi uqweqwe olunezimbobo luhambisana nokukhula kwamathambo futhi luthola umphumela omuhle kakhulu wokuqina kwesikhathi eside. Amaphethelo angaphambili nangemuva e-intramedullary rasp ahlinzeka ngokulingana okungcono kwethambo elikhanseliwe, andise indawo yokuxhumana phakathi kwe-prosthesis nethambo, futhi ahlinzeke ngendlela engcono kakhulu yokukhiya isiqu ukuvimbela isiqu ukuthi singacwili. Intamo nezinyawo ezomile zingama-degrees angu-135. Kungaba futhi umkhiqizo okhethekile wendlela ye-DAA. Izinzuzo zayo yindlela yangempela yemisipha, enesikhathi esifushane sokululama, isikhathi esifushane sokululama sokuzivocavoca nsuku zonke, ubuhlungu obuncishisiwe besiguli, isikhathi esincishisiwe sokulaliswa esibhedlela, kanye nengozi encishisiwe yokuphuma. I-femoral prosthesis iphathwa ngokushefa amahlombe ukuze kulondolozwe isisindo samathambo se-trochanter enkulu, efanelekile ukufakwa kwe-DAA okungangeni kakhulu. Isiphetho esiseduze somzimba wesibambo siyaqina, isiphetho esikude siyancishiswa, futhi ukwakheka kobude obufushane kuqinisekisa ukuzinza futhi kwenza kube lula ukufakwa.
Ubuso obungaphandle obucwebezelisiwe kakhulu besiqu sikasimende bunobungani obuhle kakhulu besimende, bulandela inkolelo-mbono yokucwila yemvelo, buvumela i-prosthesis ukuthi icwile kancane esikhaleni sikasimende, futhi yakhelwe ngobukhulu obungunxantathu ukuze kuncishiswe ukucindezeleka kwesimende. Ifakwe ipulaki elikude kanye ne-inserter ukuqinisekisa ukuthi i-prosthesis ibekwe kahle emseleni we-medullary. I-engeli yesiqu sakhe sentamo ingu-130 degrees. Lingisa i-engeli yangempela yokunyakaza kwe-hip ngezinga elikhulu kakhulu.
Njengamanje, ubuso besokhethi yensimbi buvame ukuphathwa nge-vacuum plasma titanium slurry. Isembozo esinezimbobo siyasiza ekukhuleni kwamathambo nasekuqineni isikhathi eside. Umklamo we-latch olungiselelwe kahle ukhulisa ukuqina kwendebe kanye nesembozo sangaphakathi. Siphinde sinikeze ama-socket ahlukahlukene. Ukukhetha i-lining ehambisana nezidingo zeziguli ezahlukene.
Ikhanda lebhola linekhanda lebhola le-ceramic, futhi ikhanda lebhola lensimbi liyatholakala. Ikhanda lebhola le-ceramic liyizinto zokwakha ze-BIOLOXdelta zesizukulwane sesine, ezihambisana kahle kakhulu nezinto eziphilayo, izakhiwo ezinhle zokuzungeza nokugcoba, ukuguguleka okuphansi kakhulu, futhi zihambisana ngokuphelele nesiqu segolide se-femoral. Ikhanda lebhola lensimbi lenziwe nge-cobalt-chromium-molybdenum alloy enobuchwepheshe obuphezulu bokupholisha.
Ubuso bekhanda le-bipolar elisetshenziswa ekufakweni esikhundleni se-hemi-hip lucwebezelisiwe, lune-coefficient ephansi kakhulu yokungqubuzana. Umklamo ophakathi nendawo ophindwe kabili uqinisekisa ububanzi obukhulu bokunyakaza kwejoyinti lesinqe futhi wehlisa izinga lokuguguleka. Umklamo wakudala wendandatho enkulu unamandla amahle okulwa nokukhumuka. Imininingwane eyahlukahlukene yalo mkhiqizo iyatholakala odokotela ukuthi bayikhethe ngokwezimo ezahlukene zesiguli, okuzuzisa ukululama kwesiguli kusenesikhathi.
