Thekiniki ya Vuhandzuri Xingheniso
Hi intramedullary (IM) nailing leyi kumaka ku amukeriwa eka proximal humeral fractures, ku twisisa endlelo leri faneleke ra vuhandzuri i swa nkoka[cite: 6]. Unlike plate fixation, IM nails function as load-sharing devices , leswi vulaka leswaku ku tshamiseka a swi titsheganga hi ku helela hi ku xava ka swikwirikiri eka marhambu ya osteoporotic[cite: 5]. Ku hambana loku ka xisekelo ku endla leswaku IM nailing yi pfuna ngopfu eka vavabyi lava dyuhaleke lava nga na khwalithi ya marhambu leyi nga ekhombyeni[cite: 4].
Misinya ya Misinya ya Nkoka ya Xithekiniki
- Ku Pfuxetiwa ka Anatomic: Ku vuyisela angle leyinene ya head-shaft na ku sivela ku rhurha ka varus i swa nkoka swinene [cite: 4].
- Ku tshamiseka ka le xikarhi: Hinge ya le xikarhi yi fanele ku vuyiseriwa ku sivela varus angulation [cite: 4].
- Load-Sharing Fixation: Swipikiri swa IM swinyika ku tshamiseka ka xihatla handle ko lava ku hlanganisiwa ka biological [cite: 5].
- Ndlela leyi nga ngheneriki ngopfu: Yi hunguta ku vaviseka ka tinyama to olova na nkarhi wa vuhandzuri loko ku pimanisiwa na ku khomiwa ka tipuleti leti pfulekeke [cite: 4].
Eka marhambu ya osteoporotic, IM nailing yi kombisile ku tlakuka ka biomechanical[cite: 5]. Load-sharing fixation yi pfumelela nail hi yoxe ku nyika ku tshamiseka loko yi ri karhi yi tlakusa ku tumbuluxiwa ka callus[cite: 5]. Leswi swihambanile na plate fixation, leyi rhwalelaka ndzhwalo naswona yinga endla leswaku kuva na stress-shielding.
Ndlela ya Vuhandzuri na Ndhawu yo Nghena
Endlelo ra deltoid-splitting rinyika ku paluxiwa lokunene loko riri karhi ri hunguta ku onhaka ka rotator cuff[cite: 10]. Loko ku tshoveka ku voniwe hi mahlo ya mianakanyo, ku hungutiwa ka anatomic ku fikeleriwa hi ku tirhisa nkongomiso wa fluoroscopic na tindlela to hunguta joystick.
Ku Lunghiselela Medullary Canal
Ndhawu yo nghena i ya nkoka swinene[cite: 8]. Yi vekiwile exikarhi ka supraspinous fossa naswona yi fambisana na humeral shaft, yi tiyisisa leswaku nail trajectory leyinene[cite: 10]. Kutani ntambhu yo kongomisa yi yisiwa emahlweni hi humeral canal, naswona ku endliwa reaming hi ku landzelelana ku lulamisela canal ku nghenisiwa ka implant[cite: 10].
