KALÇA PROTEZLERİNDE OLUŞAN AŞINMANIN FEMUR KAS-İSKELET SİSTEMİ TABANLI SONLU ELEMANLAR ANALİZİ İLE İNCELENMESİ

Kalça protez kullanımı artan ortalama yaşam süresine ve nüfusa bağlı olarak gün geçtikçe artmaktadır. Üstün klinik başarıya rağmen aşınmaya bağlı olarak kalça protezlerinin gevşemesi ve ağrılı süreçlerin tekrar başlaması beklenen bir durum haline gelmiştir. Bunların engellenebilmesi için yapılan çalışmalar in vitro ortamlarda test edilerek sağlık alanında gelişmeler kaydetmektdir. Bu makalede de kalça protezlerinde ki in vitro test koşullarını daha kısa sürelerde sağlamak amacıyla kas-iskelet simülasyon tanımlanan Sonlu Elemanlar Yöntemi ile analizler gerçekleştirildi. Bunun için erişkin hastaya ait femur kemiği, bu kemiğe uygun kalça protezi ve 172 adet kas birim yük değeri kullanıldı. Yapılan analizler sonucunda kas sistemlerinin aşınma derinliğini ve gerilmeleri azalttığı belirlendi.

Investigation of hip prosthesis wear with finite element analysis based on femur musculoskeletal system

The use of hip prostheses increases with increasing average life expectancy and population. In spite of the superior clinical success, loosening of the hip prostheses and the resumption of painful processes due to abrasion have become expected. In order to prevent this, the studies carried out in vitro have been tested in the field of health. In this article, in order to provide the in vitro test conditions in hip prostheses in shorter times, analyses were performed by Finite Element Method which defined musculoskeletal simulation. For this purpose, femoral bone of adult patient, hip prosthesis and 172 muscle unit load value were used. As a result of the analyzes, it was determined that the muscle systems reduce the wear depth and stresses.
