Acetabular Labrum Biyomekaniği için 3D Yazıcı Destekli Kurulum

Öz

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.

3D Printer Assisted Setup for Acetabular Labrum Biomechanics

Abstract

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.
