Equivalent stress values were determined on femur and pelvis models.Results: Maximum equivalent stress values obtained at reference femur and pelvis (RMOD)model were compared to the stress values of coxa vara (KVAR) and valga (KVAL) models.The values of coxa vara and valga models were found to be higher than the reference values.Femoral neck angle (α) alteration was more effective than femoral neck length changes forload distribution

Özet

Amaç: Bu çalışmada, femur boyun geometrik boyutlarındaki değişimler sonucu oluşandeformitelerin femur gövdesi ve pelvis üzerinde meydana getirdiği gerilmelerdeğerlendirilmiştir.Yöntem: Femur boyun geometrik boyutlarındaki değişimler sonucu oluşan ve koksa vara vevalga olarak tanımlanan alt ekstremite bozukluğu sonucunda yaklaşık 100 kg vücut ağırlığıdikkate alınarak femur diafizi ve pelvis üzerindeki gerilme ve deformasyon dağılımı incelendi.Bunun için de insan femur ve pelvis kemiklerinin birebir ölçüde katı modelleri BilgisayarlıTomografi (BT) görüntüleri yardımıyla elde edildi. İnsan vücut ağırlığı dolayısı ile uygulananyükler sonucu, elde edilen femur ve pelvis modellerdeki eşdeğer (von-misses) gerilmedeğerleri hesaplandı. Pelvis ve femur üzerinde oluşan maksimum eşdeğer gerilme alanlarıkoksa vara (KVAR) ve koksa valga (KVAL) modellerindeki pelvis üzerindeki eşdeğergerilmeler kıyaslandı.Sonuç: Referans normal model üzerinde elde edilen gerilme değerine göre daha yüksekbulundu. Bunun yanında KVAR ve KVAL modellerindeki femur üzerinde oluşan gerilmelerdeyine referans model (RMOD) femuru üzerindeki gerilmeden fazla elde edildi. Gerilmedağılımlarına göre elde edilen gerilme artışında, femur boyun açılarındaki değişim femurboyun uzunluğundaki değişime göre daha etken olduğu elde edilmiştir
