Cannulated screw fixation of fracture neck of femur in children with osteogenesis imperfecta.

Abstract

Osteogenesis imperfecta is a disorder of abnormality in collagen metabolism due to genetic defects, which causes fragility fracture in children. Fragility fracture of the neck of femur can be difficult to treat in adults. The difficulties increase exponentially in children. The challenge becomes more severe when there is an intramedullary rod in situ in the femoral shaft. It is a technically demanding work to fix fracture caused by osteogenesis imperfecta. There is hardly any published study on the difficult fixation of fracture neck of femur in osteogensis imperfecta. Therefore, we present two cases using cannulated screw fixation for this type of fracture for the benefit of other orthopaedic surgeons.
