Biomechanical analysis of the placement of fixation lag screw in different intertrochanteric hip fracture angles

Biomechanical analysis of the placement of fixation lag screw in different intertrochanteric hip fracture angles

The common surgical method for fracture fixation in the femoral neck and intertrochanteric region is the implantation a dynamic lag screw into the femoral head. However, failure rates of this fixation are high due to a cut-out of the lag screw from the femoral head. It is unclear if the lag screw po...
