Management of Periprosthetic Femur Fractures With Severe Bone Loss Using Impaction Bone Grafting Technique

Abstract 

We present a technique of femoral impaction grafting used for the treatment of periprosthetic femur fractures with severe bone loss after total hip arthroplasty. Seven patients with femoral fractures with compromise of the femoral isthmus were treated with femoral component revision using the impaction grafting bone technique. The average age was 64 years (range, 44-72 years), and 2 patients required mesh augmentation at the time of surgery. The average follow-up for this group of patients was 56 months (range, 39-92 months). Radiographic evaluation revealed healed fractures in all patients and no evidence of implant loosening at a mean of 56 months (range, 39-92 months). There were no cases of infections or dislocations in this series. Impaction grafting technique can be useful in the treatment of periprosthetic femur fractures when bone loss and canal geometry preclude the use of fully coated femoral components.
