Reconstruction of proximal femoral bone loss using circumferential structural allograft during total hip arthroplasty in a young patient.

Management of proximal femoral bone loss during hip arthroplasty in young patients is a complex problem due to the need to provide a joint with an increased longevity. While proximal femoral replacement (PFR) would be an easier solution, they are associated with poorer hip scores and decreased prosthesis survival rates which are not ideal while managing young patients. We present a case of proximal femoral bone loss in a young female - following multiple failed osteosynthesis surgeries aimed at addressing a pathological sub-trochanteric fracture - managed successfully with a circumferential allograft during total hip arthroplasty. While there is many literature reporting the use of circumferential allografts during revision hip surgery, this is the first case to the best of our knowledge where we are reporting its successful use in a complex primary hip arthroplasty case. Our successful outcome shows that reconstruction of proximal femoral bone loss using allografts in young patients should be considered prior to use of PFR in them.
