Ukuphuka kwentamo ye-femoral kuyimbangela evamile futhi engaba yingozi kakhulu kodokotela abahlinzayo bamathambo, kanye nenani elikhulu lokungahlangani kanye ne-osteonecrosis ngenxa yokutholakala kwegazi okubuthakathaka. Ukunciphisa okunembile nokuhle kokuphuka kwentamo ye-femoral kuyisihluthulelo sokulungiswa kwangaphakathi okuphumelelayo.
Ukuhlolwa Kokuncishiswa
Ngokusho kukaGarden, indinganiso yokunciphisa ukuphuka kwentamo ye-femoral esusiwe ingu-160° kwifilimu yamathambo kanye no-180° kwifilimu eseceleni. Kubhekwa njengokwamukelekayo uma inkomba ye-Garden iphakathi kuka-155° no-180° ezindaweni eziphakathi neziseceleni ngemva kokunciphisa.
Ukuhlolwa kwe-X-ray: ngemva kokunciphisa okuvaliwe, izinga lokwaneliseka kokunciphisa kufanele linqunywe ngokusebenzisa izithombe ze-X-ray ezisezingeni eliphezulu. USimom noWyman benze ama-engeli ahlukene e-X-ray ngemva kokunciphisa okuvaliwe kokuphuka kwentamo ye-femoral, futhi bathole ukuthi amafilimu e-X-ray amahle nawaseceleni kuphela abonisa ukunciphisa komzimba, kodwa hhayi ukunciphisa komzimba kwangempela. ULowell uphakamise ukuthi ubuso obugobile bekhanda le-femoral kanye nobuso obugobile bentamo ye-femoral kungaxhunyaniswa ne-S-curve esimweni esijwayelekile somzimba. ULowell uphakamise ukuthi ubuso obugobile bekhanda le-femoral kanye nobuso obugobile bentamo ye-femoral kungakha ijika elimise okwe-S ngaphansi kwezimo ezijwayelekile zomzimba, futhi uma ijika elimise okwe-S lingasheleli noma lingalingani nanoma yisiphi isikhundla ku-X-ray, kusikisela ukuthi ukuhlelwa kabusha komzimba akukafinyelelwa.
Unxantathu oguquliwe unezinzuzo ezisobala kakhulu ze-biomechanical
Isibonelo, esithombeni esingezansi, ngemva kokuphuka kwentamo ye-femur, ingxenye yokuphuka ibhekene nokucindezeleka okuvame ukucindezelwa engxenyeni engenhla kanye nokucindezelwa engxenyeni engezansi.
Izinhloso zokulungisa ukuphuka yilezi: 1. ukugcina ukulingana okuhle kanye 2. nokulwa nokucindezeleka kokudonsa ngangokunokwenzeka, noma ukuguqula ukucindezeleka kokudonsa kube ukucindezeleka kokucindezela, okuhambisana nesimiso sokubopha ukucindezeleka. Ngakho-ke, isixazululo sikanxantathu oguquliwe esinezikulufo ezimbili ngaphezulu ngokusobala singcono kunesixazululo sikanxantathu esi-orthotic esinesikulufo esisodwa kuphela ngaphezulu ukuze silwe nokucindezeleka kokudonsa.
Kubalulekile ukulandelana kwezikulufo ezintathu lapho kuphuka intamo ye-femoral:
Isikulufu sokuqala kufanele sibe yisihloko senxantathu eguquliwe, ngesikhathi se-femoral;
Isikulufu sesibili kufanele sibekwe ngemuva kwesisekelo sonxantathu oguquliwe, eduze kwentamo ye-femoral;
Isikulufu sesithathu kufanele sibe ngaphambili onqenqemeni olungezansi lonxantathu oguquliwe, ohlangothini lokucindezeleka kokuqhekeka.
Njengoba ukuphuka kwentamo ye-femoral kuvame ukuhlotshaniswa ne-osteoporosis, izikulufo zine-screw grip elinganiselwe uma zinganamatheli onqenqemeni futhi ithambo lincane endaweni ephakathi, ngakho-ke ukunamathelisa onqenqemeni eduze ngangokunokwenzeka ne-subcortex kunikeza ukuzinza okungcono. Indawo efanele:
Izimiso ezintathu zokulungisa izinzipho ezingenalutho: eduze komphetho, okulinganayo, imikhiqizo eguquliwe
Okuseduze kusho ukuthi izikulufo ezintathu zingaphakathi kwentamo ye-femur, eduze kakhulu ne-cortex engaphandle ngangokunokwenzeka. Ngale ndlela, izikulufo ezintathu zizonke zidala ingcindezi ebusweni bonke bokuqhekeka, kanti uma izikulufo ezintathu zingahlukani ngokwanele, ingcindezi ivame ukuba njengephuzu, ingazinzile futhi ingamelani kakhulu ne-torsion kanye ne-shear.
Ukuzivocavoca Okusebenzayo Ngemva Kokuhlinzwa
Ukuzivocavoca kokuthwala isisindo okukhomba uzwane kungenziwa amasonto ayi-12 ngemva kokulungiswa kokuphuka, kanti ukuzivocavoca kokuthwala isisindo okungaphelele kungaqalwa ngemva kwamasonto ayi-12. Ngokuphambene nalokho, ngokuphuka kohlobo lwe-Pauwels III, kunconywa ukulungiswa nge-DHS noma i-PFNA.
