Testing system for the comparative evaluation of greater Trochanter re-attachment devices

摘要

The scope of this study was to propose and validate a specialized test bench that applies biaxial forces on an orthopedic model of Greater Trochanter (GT) re-attachment with integrated cable tension measurement. Stability of the GT fragment is evaluated using a custom triplanar video movement-analysis system with the first camera's field of view (FOV) corresponding to the GT osteotomy plane and the second and third camera's FOVs corresponding to the median plane of the femur in frontal and posterior views, respectively. A typical experimentation and its critical analysis conclude the paper.
