The full abstract can be found at the OAR website: Evaluation of Fixation Constructs for Femoral Neck Fracture: a Sawbones Biomechanical Model This document details a biomechanical study comparing two different femoral neck fracture fixation devices using Sawbones femur models. The research focused on evaluating the SimpliFix Hip System against a standard cannulated screw construct in terms of maintaining fracture gap area, resisting femoral head rotation, preventing screw displacement, and cycles to failure. The study's methods involved preconditioning and dynamic cyclic loading to mimic real-world conditions. Results indicated the SimpliFix system significantly outperformed the control group in resisting fracture gap collapse and screw displacement. The findings suggest that the SimpliFix system could clinically improve outcomes by reducing complications like femoral neck shortening and gait disturbance.
