Abstract

6 pairs of fresh frozen calf femora were obtained and randomly divided into 4 equal group. One of the 3 different intra-medullary implants was fixed in place and one group was taken as control. A transverse saw cut was made at the sub-trochanteric region to produce an unstable osteotomy in 3 groups . Bending and torsional stiffness and failure load under axial loading were measured in vitro in each group and compared with each other. Gamma nail was found to be much more stiff than the other two nails

Özet

6 çift dana femuru alınarak rastgele her biri 3' er femurdan oluşan 4 gruba ayrıldı. 3 gruba Ender çivileri, Grosse -Kempf çivisi ve Gamma çivisi uygulandı. 4 üncü grup kontrol grubu olarak alındı. İmplant uygulanan femurlarda subtrokanterik bölgede havalı kesici ile instabil transvers bir osteotomi yapıldı. Tüm femurlann in vitro olarak bükülme, torsiyon sertlikleri ve aksiyel kompresyon altındaki maksimum yük taşıma kapasiteleri karşılaştırıldı. Gamma çivisi biomekanik açıdan diğer 2 implanta göre daha üstün bulunmuştur
