AB  - The hip joint is responsible for providing a support of the weight of upper body. It provides a force transmission from the axial skeleton to the lower extremities. Therefore, labral tears might lead to serious outcomes with time; such as hip pain, degeneration, even arthritis. In this study, we aimed to determine human acetabular labrum mechanical properties with the help of a newly designed compression test set-up. Study was performed with 9 human acetabular labrum tissues obtained from volunteers (with the average age of 65,5±8,1; 4 female and 5 male). The samples were evaluated separately by using a 3D printer designed test set-up with a 100% humidity and a displacement rate of 10 mm/min at 24(±1) °C. The data up to 70 N loading were used for biomechanical evaluations. The average elastic modulus (0.022 MPa ± 0.001) was evaluated with the maximum stress (1.169 MPa ± 0.052) and the maximum strain (53.09 ± 2.643) at 70 N loading. In conclusion, the obtained data verifies that the test set-up is like to anatomical design and data is acceptable.

N2  - Kalça eklemi, üst ekstremitenin ağırlığının desteklenmesinden sorumludur. Eksenel iskeletten alt ekstremitelere kuvvet iletimini sağlar. Bu nedenle, labral yırtıklar zamanla ciddi sonuçlara yol açabilir; kalça ağrısı, dejenerasyon, hatta artrit gibi. Bu çalışmada yeni tasarlanan kompresyon testi düzeneği sayesinde insan asetabular labrumunun mekanik özelliklerinin belirlenmesi amaçlanmıştır. Çalışma, 9 adet gönüllüden (yaş ortalaması 65,5 ± 8,1; 4 kadın ve 5 erkek) elde edilen insan asetabular labrum dokusu ile gerçekleştirilmiştir. Örnekler, % 99 nem koşulu sağlanarak ve 24 (± 1) ° C sıcaklıkta 10 mm / dk yer değiştirme hızı ile 3D yazıcı tasarımlı bir test düzeneği kullanılarak değerlendirilmiştir. Biyomekanik değerlendirmeler için 70 N'ye kadar yüklenme altındaki veriler kullanılmıştır. Ortalama elastik modül değeri (0.022 MPa ± 0.001), maksimum gerilme (1.169 ± 0.052) ve maksimum yer değiştirme (53.09 ± 2.643) değerleri elde edilmiştir. Sonuç olarak, elde edilen veriler test düzeneğinin anatomik yapıya benzediğini ve verilerin kabul edilebilir aralıklarda olduğunu doğrulamaktadır.
