Abstract
INTRODUCTION AND IMPORTANCE: Femoral fractures are common in the patients with osteopetrosis and multiple treatment strategies have been described with varying results. However, there is a paucity of literature describing the treatment of recurrent fractures and subsequent deformity. CASE PRESENTATION: We present detailed revision strategies and long-term follow-up results of a patient with osteopetrosis who suffered unsuccessful operative treatment using the plate-screw system (recurrent femoral shaft fracture and implant failure). CLINICAL DISCUSSION: The success of revision surgery of osteopetrosis is based on good preoperative planning, appropriate selection of fixation methods, and a meticulous approach during surgery. The combined application of the expert adolescent lateral femoral nail, the reconstruction locked plate, and bone morphogenic protein (BMP)-7 in this patient achieved good clinical results. CONCLUSION: In the treatment of failed plated and recurrent osteopetrotic femoral shaft fractures, the combination of nails and plating presents an alternative, potentially more successful, revision strategy.
