Medial Calcar Restoration Using Femoral Head Autograft in Conversion Hip Arthroplasty for Failed Fixation after an Unstable Intertrochanteric Hip Fracture: A Case Report and Technique Description.

Introduction: The calcar femorale helps manage compressive loads on the femoral head and is an essential component in determining intertrochanteric (IT) femur fracture stability. Fracture fixation can be complicated when primary fixation techniques, such as cephalomedullary nailing fail. Unstable IT femur fractures involving disruption of the medial calcar present additional fixation challenges.
