Kalça Protezlerinde Oluşan Aşınmanın Femur Kas-İskelet Sistemi Tabanlı Sonlu Elemanlar Analizi ile İncelenmesi

Kalça protez kullanımı artan ortalama yaşam süresine ve nüfusa bağlı olarak gün geçtikçe artmaktadır. Üstünklinik başarıya rağmen aşınmaya bağlı olarak kalça protezlerinin gevşemesi ve ağrılı süreçlerin tekrar başlamasıbeklenen bir durum haline gelmiştir. Bunların engellenebilmesi için yapılan çalışmalar in vitro ortamlarda testedilerek sağlık alanında gelişmeler kaydetmektedir. Bu makalede de kalça protezlerinde ki in vitro testkoşullarını daha kısa sürelerde sağlamak amacıyla kas-iskelet simülasyonu tanımlanan Sonlu Elemanlar Yöntemiile analizler gerçekleştirildi. Bunun için erişkin hastaya ait femur kemiği, bu kemiğe uygun kalça protezi ve 172adet kas birim yük değeri kullanıldı. Yapılan analizler sonucunda kas sistemlerinin uygulanması aşınmaderinliğini ve gerilmeleri azalttığı belirlendi.

Investigation of Wear in Hip Prosthesis by 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, analyzes 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 analysis, it was determined that the application of muscle systems decreased the depth of wear and tensions.
