Biomechanical Comparison of Graft Preparation Techniques for Distal Radioulnar Joint Reconstruction

Description

The presentation is delivered by AlJarrah AlEidan, who starts by declaring no conflicts of interest. The focus of the study is a biomechanical comparison of graft preparation techniques for use in digital radiology and joint reconstruction, specifically addressing distal radioulnar joint (DRUJ) instability, a common condition that leads to wrist pain following distal radius fractures. AlEidan outlines various treatment methods available, including tendon grafts and suture options, and discusses the objectives of their study, which involved creating a model to simulate DRUJ allograft reconstruction for mechanical testing.



The methodology includes detailing the experimental setup, which utilizes cadaveric bovine Achilles tendons that undergo specific mechanical tests to evaluate properties such as failure loads and stiffness. The presentation discusses various graft configurations tested, including the application of fiber wire suture with different spacing intervals. Results indicate that while suture alone showcases high stiffness, it is biomechanically inferior to tendon grafts in terms of failure load. Limitations of the study are acknowledged, including the use of bovine tendons and the non-physiological loading conditions that may not accurately reflect in vivo scenarios. AlEidan concludes the presentation by suggesting future directions involving testing with other tendon types and suture materials. The presentation ends with a thank you.
