Intertrochanteric fracture fixation with dynamic hip screw: is tip-apex distance measurement useful for predicting fixation failure?

Intertrochanteric fracture fixation with dynamic hip screw: is tip-apex distance measurement useful for predicting fixation failure?

Introduction: Application of dynamic hip screw (DHS) implant for the treatment of unstable intertrochanteric fractures continues to raise concern related to risk of lag screw cut-out with or without subsequent damage to the acetabulum. Measurement of tip-apex distances (TAD) has been recommended to...
