Summary
<p>Proximal femoral fractures are critical orthopedic injuries frequently encountered in geriatric populations, often leading to substantial reductions in mobility and overall quality of life. Intramedullary proximal femoral nails, commonly employed in the surgical fixation of these fractures, serve a vital function in maintaining fracture stability and promoting osseous healing. One of the primary determinants of clinical success for these implants is their mechanical integrity particularly their resistance to torsional loads, which plays a significant role in long-term performance and the prevention of implant failure or postoperative complications. However, existing test systems often lack the capability to accurately and reproducibly simulate the torsional stresses encountered in vivo. Consequently, this study focuses on the design and development of a dedicated torsion test device specifically engineered to assess the torsional performance of proximal femoral nails under physiologically relevant loading conditions. The device is intended to apply controlled torsional forces in a laboratory environment, thereby replicating clinical loading scenarios and enabling quantitative evaluation of implant behavior under such stresses.</p><p>The proposed device is expected to facilitate the mechanical validation of novel implant designs and provide a platform for comparative performance analysis of existing systems. Furthermore, the device is anticipated to contribute significantly to orthopedic implant R&D efforts by enabling the development of more robust, long-lasting, and anatomically compatible fixation solutions.</p>
