Izikulufo zokuvimba zisetshenziswa kabanzi emtholampilo, ikakhulukazi ekuqiniseni izinzipho ezinde zangaphakathi kwe-medullary.
Empeleni, imisebenzi yezikulufo ezivimbayo ingafingqwa njengezindlela ezimbili: okokuqala, ukunciphisa, kanti okwesibili, ukwandisa ukuzinza kokuqina kwangaphakathi.
Ngokuphathelene nokunciphisa, isenzo 'sokuvimba' sesikulufu sokuvimbela sisetshenziswa ukushintsha indlela yokuqala yokuqinisa kwangaphakathi, kufezwe ukunciphisa okufiselekayo nokulungisa ukuhambisana. Kulesi simo, isikulufu sokuvimbela sidinga ukubekwa endaweni 'engafanele ihambe', okusho indawo lapho ukulungiswa kwangaphakathi kungafunwa khona. Uma sithatha i-tibia ne-femur njengezibonelo:
Kwi-tibia: Ngemva kokufaka ucingo oluqondisayo, lubekwa ngokumelene ne-cortex engemuva ye-tibial shaft, luphambuka kusukela phakathi komsele we-medullary. Esiqondisweni 'esingafunwayo', ikakhulukazi isici sangemuva se-metaphysis, kufakwa isikulufu esivimbayo ukuze siqondise ucingo phambili kumsele we-medullary.
I-Femur: Emfanekisweni ongezansi, kuboniswa uzipho lwe-femoral olubuyela emuva, lapho iziphetho zokuphuka zibonisa ukugoba kwangaphandle. Uzipho lwe-intramedullary lubekwe eceleni kwengxenye yangaphakathi yomsele we-medullary. Ngakho-ke, kufakwa isikulufu esivimbayo ohlangothini lwangaphakathi ukuze kufezwe ushintsho endaweni yozipho lwe-intramedullary.
Ngokuphathelene nokuthuthukisa ukuzinza, izikulufo ezivimbayo ekuqaleni zazisetshenziswa ukuqinisa ukuzinza kokuphuka okufushane emaphethelweni okuphuka komgodi we-tibial. Ngokuvimba ukunyakaza kwezinzipho zangaphakathi kwe-medullary ngesenzo sokuvimba sezikulufo emaceleni angaphakathi nangaphandle, njengoba kuboniswe esibonelweni sokuphuka kwe-femoral intercondylar kanye ne-supracondylar ngezansi, ukuzinza kweziphetho zokuphuka kungaqiniswa. Lokhu kusiza ukuvimbela ukunyakaza kokujika kwezinzipho zangaphakathi kwe-medullary kanye nezingcezu zamathambo ezikude.
Ngokufanayo, ekuqiniseni ukuphuka kwe-tibial ngezipikili zangaphakathi kwe-medullary, ukusetshenziswa kwezikulufo ezivimbayo kungasetshenziswa futhi ukuthuthukisa ukuzinza kweziphetho zokuphuka.
