Cov lus qhia kho mob

Standard cortical screws yog siv rau cov pob txha diaphyseal, nrog lub taub hau symmetrical (3.5 + 4.5) thiab asymmetrical threads.
Standard cancellous pob txha screws yog siv rau metaphysis lossis epiphysis, nrog loj txheej kab thiab sib sib zog nqus xov.
Lag ntsia hlau thev naus laus zis muaj ob yam khoom siv tshuab: 1 lub voj voog quab yuam (kev sib txhuam quab yuam) raws cov xov, 2 lub axial quab yuam thaum nruj, cov ntsia hlau ntsia hlau los yog zawv zawg qhov tso cai rau cov pob txha tawg thaiv kom rub mus rau lub taub hau ntsia hlau.
