EFFECTS OF SALTER PELVIC OSTEOTOMY ANGLE ON CONTACT AREA AND PRESSURE DISTRIBUTION IN THE HIP JOINT: AN EXPERIMENTAL STUDY
Öz
The hip dysplasia is described by an irregular relation between the femoral head and the acetabulum. Insufficient coverage of the femoral head by the acetabulum leads the development of dysplasia in the incongruity hip joint. Several osteotomies are carried out for treatment by changing with coverage angle of the femoral head in the hip joint. In this paper, the effects of osteotomy techniques used in the surgery applications on the coverage angle are investigated experimentally. Salter osteotomy technique was applied on a patient-specific artificial hip models manufactured at different osteotomy angles. The contact pressure distribution and area were measured by using Fuji Film Prescale sensor in the hip joint. The results were compared with each other. The average contact pressure expectedly decreases as long as osteotomy coverage angle increases but, the contact area decreases unexpectedly

SALTER PELVİK OSTEOTOMİ AÇISININ KALÇA EKLEMİNDE TEMAS ALANINA VE BASINÇ DAĞILIMINA ETKİLERİ: DENEYSEL ÇALIŞMA
Öz
Kalça displazisi femur başı ve asetabulum arasındaki uyumsuzluk olarak tanımlanır. Asetabulum tarafından femur başının yetersiz örtünmesi uyumsuz kalça eklemlerinde displazi oluşumuna yol açar. Kalça ekleminde tedavi amaçlı femur başının örtünme açısının değiştirilmesi ile çeşitli ostetotomiler gerçekleştirilmektedir. Bu çalışmada örtünme açısı üzerine cerrahi uygulamalarda kullanılan osteotomi tekniklerinin etkileri deneysel olarak incelendi. Farklı osteotomi açılarında yapay olarak üretilen hastaya özgü kalçada Salter osteotomi tekniği uygulandı. Kalça ekleminde Fuji Film sensör kullanılarak temas basınç dağılımı ve alanı hesaplandı. Sonuçlar kendi arasında kıyaslandı. Osteotomi örtünme açısı arttıkça ortalama temas basıncı beklendiği gibi azalırken temas alanı beklenmedik şekilde azaldı
