Umcimbi wokukhetha ubukhulu bezipikili ze-intramellary kumathambo amade omzimba wemilenze engezantsi.

I-Intramellary saising ngumgangatho wegolide kunyango lonyango lwe-diaphyseal tyhali zamathambo amalanga amaxesha aphantsi. Inika izibonelelo ezifana noxinzelelo oluncinci kunye namandla aphezulu e-bimobichanici, ezenza ukuba isetyenziswe kakhulu kwi-tibilial, i-femoral, kunye ne-theimeral faft. Ngokokhenketho, ukukhetha ububanzi be-intramerary ye-Intramellary kuhlala kuthanda isikiphu esinokufakelwa okunokwenzeka, ukuqinisekisa uzinzo oluphambili. Nangona kunjalo, nokuba ubukhulu bendlela ye-intramellary ichaphazele ngokuthe ngqo i-progenosis progunosis ihleli ingaqondakali.

Kwinqaku eladlulayo, sixoxe ngesifundo sokuhlola ifuthe lezipikili ze-intramedulting kwi-bone ephilisa izigulana ezingaphezulu kwe-50 nge-prostrokancric gwenxa. Iziphumo ezibonisile akukho mahluko manani kunyango lokuphilisa kunye namaxabiso aphindayo phakathi kweqela le-10mm kunye neqela ngezipikili ezinamagqabi ali-10mm.

Iphepha elipapashwe ngonyaka wama-2022 ngabafundi abavela kwi-Taiwan kwiPhondo bafika kwisigqibo esifanayo:

Isifundo esibandakanya izigulana ezingama-257, ezichazwe ngezipikili ze-Inmomellary ezi-10mm, i-11mm, i-12mm, kunye ne-12mm, kunye ne-13mm, ezahlulahlula izigulana zibe ngamaqela amane esekwe kwi-Nagemeter yeZibhalo. Kwafunyaniswa ukuba kwakungekho maxabiso manani kunyango lokuphilisa phakathi kwamaqela amane.

Ke, ngaba le yimeko yefraftial ye-tibial shaft?

Kwisifundo sokulawulwa kwetyala esibandakanya abaguli abangama-60, abaphandi bahlulahlula izigulana ezingama-60 ngokulinganayo kumaqela amabini angama-30. Iqela A lalilungisiwe ngezipikili ezinqabileyo (9mm kubafazi kunye ne-10mm kumadoda), ngelixa iqela le-B lalimiselwayo (i-11mm yabasetyhini kunye ne-12mm yamadoda):

Iziphumo zibonakalise ukuba akukho ngqiqweni kwiziphumo zeklinikhi okanye icinga phakathi kwezipikili ezinqabileyo nezingathandekiyo. Ukongeza, izikhonkwane ezincinci ze-intramellary zadityaniswa kunye ne-sugoroscopy amaxesha ngamaxesha. Nokuba isetyenzisiwe nakwenziwa isipikili okanye isikhonkwane esincinci se-diameter, iphinde yasebenza ngaphambi kokufakwa kwezipikili. Ababhali bacebisa ukuba i-tibial ye-tibial ye-tibial fibial shaft, isikhonkwane esincinci se-disramerlary sinokusetyenziselwa ukulungiswa.
