Osteopetrosis or Albers-Schönberg disease is a rare inherited skeletal disorder characterized by increased osteodensity and modeling defects. The fragility of such dense bone may lead to an increased incidence of fractures, especially on the hip and proximal femur. These fractures can pose problems during surgery, as the bones are hard and no medullary cavity is available for intramedullary nailing. Here we report our experience of two sisters who both presented with a subtrochanteric fracture that was fixed using a distal femoral locking compression plate (DF-LCP; Synthes, Obedors, Switzerland) of the contralateral side.
