Abstract

Infected gap nonunion in long bone fractures is a common problem seen in our setup after compound injuries. Treatment options are limited such as Ilizarov ring fixation with bone transport, vascularised bone graft etc. These techniques require expertise and are associated with their own morbidity and complications. A novel technique called as induced membrane formation, is used to bridge a gap nonunion of more than 5 cm using bone cement as a spacer in first stage and autologous cancellous bone graft to fill the gap once infection is healed along with a bridging plate in second stage.

Keywords: Bone cement; Cancellous bone graft; Induced membrane formation; Infected gap nonunion.
