Ukubuka Konke Komkhiqizo

I-hip joint iqukethe isokhethi, ulwelwesi, ikhanda lebhola, isibambo nezinye izakhi.Ingxenye ngayinye inezinto eziningana kanye nokucaciswa.Ukukhethwa kwezinto kanye nemodeli ngokusho kokuhlinzwa okuhlukile kwe-hip.Kunezinhlobo ezimbili zeziqu: iziqu zikasimende kanye neziqu ezihlangene ze-bio.Isiqu sebhayoloji esiyisebenzisayo njengamanje emhlabeni wonke siwumklamo omise okwe wedge, osetshenziselwa ukuthuthukisa ukudluliswa kwengcindezi nokuthuthukisa ukuzinza kwesiphetho esingemuva sesiqu.Idizayini yesiphetho sesiqu esithuthukisiwe ikhuphula ukuzinza kwekhanda lebhola, futhi idizayini yentamo ephucuzeke kakhulu iyacwengwa ukuze kuthuthukiswe ububanzi bokunyakaza kwe-prosthesis.I-proximal groove i-perpendicular to the direction of stress conduction, ehambisana ne-osseointegration esheshayo kanye nokuzinza okuhle kokuqala.Ingaphezulu lomzimba we-stem lihlanganiswe ngokugcwele ne-plasma titanium slurry, futhi ukumbozwa kwe-porous kuvumelana nokungena kwamathambo futhi kuthola umphumela omuhle kakhulu wokulungisa wesikhathi eside.Amaphethelo angaphambili nangemuva we-rasp ye-intramedullary ahlinzeka ngokulingana okungcono kokucindezela ethanjeni elikhansela, akhulise indawo yokuxhumana phakathi kwe-prosthesis nethambo, futhi anikeze indlela engcono kakhulu yokukhiya isiqu ukuvimbela isiqu ukuthi singacwili.Intamo eyomile nezinyawo ziyi-135 degrees.Kungaba futhi umkhiqizo okhethekile wendlela ye-DAA.Izinzuzo zayo ziyindlela yangempela ye-intermuscular, enesikhathi esifushane sokululama, isikhathi esifushane sokuphumula sokuzivocavoca nsuku zonke, ukunciphisa ubuhlungu besiguli, ukunciphisa isikhathi sokulaliswa esibhedlela, nokunciphisa ingozi yokuxoshwa.I-prosthesis yesifazane iphathwa ngokushefa ehlombe ukuze kulondolozwe isisindo samathambo e-trochanter enkulu, elungele ukufakwa kwe-DAA okungavamisile kancane.Isiphetho esiseduze somzimba wesibambo sijiyile, isiphetho esikude siyancishiswa, futhi idizayini yobude obufushane iqinisekisa ukuzinza futhi yenza kube lula ukufakwa.
Indawo engaphandle epholishelwe kakhulu yesiqu sikasimende inokuhambisana okuhle kakhulu kukasimende, ilandela inkolelo-mbono yokucwila yemvelo, ivumela i-prosthesis ukuthi icwile kancane emgodleni kasimende, futhi iklanywe ngobukhulu obunxantathu ukuze kuncishiswe ukucindezeleka kukasimende.Ifakwe ipulaki eyi-distal kanye nesifaki sokuqinisekisa ukuma ngendlela efanele kwe-prosthesis kumsele we-medullary.I-engeli ye-stem yentamo yakhe ingama-degree angu-130.Lingisa i-engeli yokunyakaza kwe-hip yangempela kakhulu.
Njengamanje, ingaphezulu lesokhethi yensimbi livame ukuphathwa nge-vacuum plasma titanium slurry.I-porous coating isiza ekungeneni kwamathambo kanye nokulungiswa kwesikhathi eside.Idizayini ye-latch eyenziwe kahle yandisa ukuzinza kwenkomishi kanye nolwelwesi lwangaphakathi.Siphinde sihlinzeke ngezinhlobonhlobo zamasokhethi.Ukukhethwa kolayini ukuze kuhambisane nezidingo zeziguli ezahlukene.
Ikhanda lebhola linekhanda lebhola le-ceramic, futhi ikhanda lebhola lensimbi liyatholakala.Ikhanda lebhola le-ceramic liyisizukulwane sesine se-ceramic material eyinhlanganisela ye-BIOLOXdelta, ene-biocompatibility enhle kakhulu, izakhiwo ezinhle zokujikeleza nezokugcoba, ukugqokwa kwe-ultra-low, futhi ifaniswe ngokuphelele ne-taper yegolide.isiqu sesifazane.Ikhanda lebhola lensimbi lenziwe nge-cobalt-chromium-molybdenum alloy enobuchwepheshe obuphezulu obupholishelwe phezulu.
Ingaphezulu lekhanda le-bipolar elisetshenziswe esikhundleni se-hemi-hip liyapholishwa, libe ne-coefficient ephansi kakhulu yokungqubuzana.Idizayini ephakathi nendawo ekabili iqinisekisa ibanga eliphezulu lokunyakaza kwelunga le-hip futhi inciphisa izinga lokuguga.Idizayini yakudala yokukhiya indandatho enkulu inokusebenza okuhle kokulwa nokugudluka.Ukucaciswa okuhlukahlukene kwalo mkhiqizo kuyatholakala ukuze odokotela bakhethe ngokuya ngezimo ezahlukahlukene zesiguli, okuzuzisa ukululama kwesiguli kusenesikhathi.
