Emkhakheni othuthukayo wokunakekelwa kwe-orthopedic trauma, ukukhethwa kokufakelwa kudlala indima ebalulekile empumelelweni yokuhlinzwa, ikakhulukazi ezimeni ezibandakanya ukuphuka okuyinkimbinkimbi.
Phakathi kwezixazululo eziphumelela kakhulu ezitholakalayo namuhla ipuleti lokwakhiwa kabusha kwe-anatomical 120 ° lokukhiya, idivayisi eyakhelwe ngokukhethekile ukubhekana nezinselele zezakhiwo eziyinkimbinkimbi ze-anatomical-ikakhulukazi ezindaweni ze-pelvic kanye ne-acetabular.
Idizayini Ye-Anatomically Precontoured ye-Better Bone Fit
Esinye sezici ezibalulekile ze-ukukhiya kabusha ipuleti le-anatomical 120°yisimo sayo se-anatomical esinqunyelwe ngaphambili. Ngokungafani namapuleti avamile aqondile adinga ukugoba okubalulekile kwangaphakathi kokuhlinzwa, leli cwecwe limise okwengaphambili ukuze lifane nokugoba okungokwemvelo kwethambo eliqondiwe, elifana nomphetho we-pelvic noma ilium. Lokhu kunciphisa isidingo sokushintshwa ngesandla ngesikhathi sokuhlinzwa, konga isikhathi nokunciphisa ingozi yokukhathala kwepuleti noma ukungahambi kahle.
Kodokotela abahlinzayo bamathambo, ipuleti elihambisana ngokwemvelo nethambo lamathambo linikeza ukuhambisana kwe-anatomical okuphakeme, okuthuthukisa ngokuqondile ukuzinza nokuthuthukisa imiphumela yokuphulukisa. Ucwaningo luye lwabonisa ukuthi amapuleti ane-precontoured anganciphisa isikhathi sokuhlinzwa kuze kufike ku-20% futhi anciphise ukuhlukumezeka kwezicubu ezithambile ngenxa yokufaneleka kangcono.
120° I-engeli: Idizayinelwe Amajiyometri Ayinkimbinkimbi
I-engeli engu-120° efakwe ekwakhiweni ibaluleke kakhulu ezindaweni zokuphuka lapho amapuleti avamile anomugqa awefushane. Lokhu kulungiselelwa kwe-angular kwenza odokotela abahlinzayo bakwazi ukubhekana nokuphuka kwe-multi-planar, ikakhulukazi lezo ezithinta i-acetabulum noma i-iliac crest, lapho ijika lemvelo kanye nokuphambuka kwe-anatomical kukhona.
Le-angularity eyakhelwe ngaphakathi iphinde isize ekugcineni i-geometry yokulungisa efiselekayo futhi iqinisekisa ukuthi izikulufu zokukhiya zingaqondiswa ngokuqondile ethanjeni le-cortical lekhwalithi ephezulu, okwandisa ukuqina kokwakha nokunciphisa ingozi yokuxegiswa kwezikulufu.
I-Locking Mechanism Yokulungiswa Okuqinile
Ipuleti lihlanganisa indlela yesikulufu sokukhiya, esinikeza ukuqina kwe-engeli engaguquki okubalulekile emathanjeni e-comminuted noma e-osteoporotic. Isixhumi esibonakalayo sokukhiya phakathi kwepuleti nezikulufu siguqula isakhiwo sibe isilungisi sangaphakathi, sinciphise ukunyakaza okuncane endaweni yokuphuka futhi sikhuthaze ukuhlanganisa kwangaphambili kanye nokuphola ngokushesha kwamathambo.
Ikakhulukazi, lapho isetshenziselwa ukwakhiwa kabusha kwe-pelvic noma i-acetabular, ubuchwepheshe bokukhiya bubonise amazinga aphansi ezinkinga kanye nokuthuthukiswa kokumelana kwe-biomechanical kumandla ezindaweni ezinesisindo.
Ukusebenza Okuthuthukisiwe Kokuhlinza Nemiphumela
Emaqenjini abahlinzayo, idivayisi ehlanganisa ukulingana kwe-anatomical nokuzinza kokukhiya ihumusha ekugelezeni komsebenzi okuhleliwe kanye nokulungiswa okumbalwa kwangaphakathi kokuhlinzwa. Isidingo esincishisiwe sokugoba noma sokwakheka kabusha asifinyezi nje kuphela isikhathi sokusebenza kodwa futhi sinciphisa ukuwohloka okungaba khona kwepuleti, okungafaka engozini amandla okufakelwa.
Ngaphezu kwalokho, ukufanisa okungcono kwe-anatomical kuthuthukisa ukuxhumana kwe-plate-bone, okubalulekile ekwabelaneni komthwalo kanye nokuzinza kwesikhathi eside, ikakhulukazi ezigulini ezidinga kakhulu.
Izicelo Ezimweni Eziyinkimbinkimbi Zokuphuka
Ipuleti lokukhiya kabusha le-anatomical 120° livame ukusetshenziswa ku:
Ukuphuka kwe-Pelvic kanye ne-acetabular
I-Iliac wing reconstructions
Ukuqhekeka kwamathambo amade ngokukhubazeka kwe-angular
Ukulungiswa kokuphuka kwe-Periprosthetic
Ukuguquguquka kwayo kanye nokuhambisana kwe-anatomical kwenza kube ukukhetha okuthandwayo kwezikhungo zokuhlukumezeka kwamathambo, ikakhulukazi ezimeni eziyinkimbinkimbi lapho ukunemba kubaluleke kakhulu.
Lapho welapha ukuphuka okuyinkimbinkimbi, ikakhulukazi ezifundeni ezinenselelo ye-anatomically njenge-pelvis noma i-acetabulum, i-implant design ibalulekile. Ipuleti lokwakha kabusha lokukhiya le-anatomical 120° linikeza ibhalansi ephelele yokulingana kwangaphambilini, ukuzinza kwe-angular, nokulungiswa kokukhiya—okuthuthukisa kokubili ukusebenza kahle kokuhlinzwa kanye nemiphumela yesiguli.
Uma ufuna okokufaka okuthembekile, okunobungane kudokotela ohlinzayo okwenzelwe izidingo eziyinkimbinkimbi zokwakha kabusha, iShuangyang Medical inikeza amapuleti ekhwalithi ephezulu e-anatomical 120° akhiqizwe ukuze ahlangabezane nezindinganiso eziqinile zezokwelapha futhi enziwe ngendlela oyifisayo ezidingweni zakho zomtholampilo.
