Izikrufu zokuvalela zisetyenziswa kakhulu kwizonyango, ingakumbi ekuqiniseni izipikili ezinde zangaphakathi kwe-medullary.
Ngokwenyani, imisebenzi yezikrufu ezithintelayo ingashwankathelwa kabini: okokuqala, ukunciphisa, kwaye okwesibini, ukonyusa uzinzo lokuqina kwangaphakathi.
Ngokuphathelele ukunciphisa, isenzo 'sokubhloka' sesikrufu sokuthintela sisetyenziselwa ukutshintsha indlela yokuqala yokulungisa kwangaphakathi, ukufezekisa ukunciphisa okufunekayo kunye nokulungelelanisa ulungelelwaniso. Kule meko, isikrufu sokuthintela kufuneka sibekwe kwindawo 'engafanele ihambe', oko kuthetha indawo apho ukulungiswa kwangaphakathi kungafunwa khona. Ukuthatha i-tibia kunye ne-femur njengemizekelo:
Kwi-tibia: Emva kokufaka ucingo olukhokelayo, lubekwe ngokuchasene ne-posterior cortex ye-tibial shaft, luphambuka kumgca ophakathi we-medullary canal. Kwicala 'elingafunekiyo', ngakumbi kwicala elingasemva le-metaphysis, kufakwa isikrufu esivimbayo ukuze sikhokele ucingo phambili ecaleni kwe-medullary canal.
I-Femur: Kumfanekiso ongezantsi, kuboniswe uzipho lwe-femoral olubuyela umva, apho iziphelo zokuqhekeka zibonisa ukugoba kwangaphandle. Uzipho lwe-intramedullary lubekwe kwicala langaphakathi lomjelo we-medullary. Ke ngoko, kufakwa isikrufu esivimbayo kwicala langaphakathi ukuze kufezekiswe utshintsho kwindawo ye-intramedullary.
Ngokuphathelele ukuphucula uzinzo, izikrufu ezivimbayo zasetyenziswa ekuqaleni ukuqinisa uzinzo lwezaphuko ezimfutshane eziphelweni zezaphuko ze-tibial shaft. Ngokuthintela ukuhamba kwezipikili zangaphakathi ngesenzo sokuvala sezikrufu kumacala angaphakathi nangaphandle, njengoko kubonisiwe kumzekelo wezaphuko ze-femoral intercondylar kunye ne-supracondylar ezingezantsi, uzinzo lwezaphuko lunokomelezwa. Oku kunceda ukuthintela intshukumo yokujika kwezipikili zangaphakathi kunye neziqwenga zamathambo ezikude.
Ngokufanayo, ekulungiseni ukwaphuka kwe-tibial ngeenzipho zangaphakathi, ukusetyenziswa kwezikrufu ezithintelayo kunokusetyenziswa ukuphucula uzinzo lweziphelo zokuqhekeka.
