Tongue and groove (v-shaped) osteotomy in treatment of non-union of long bones - a novel surgical technique.

摘要

Four patients treated for non-union of humerus (closed injury) and one for non-union of femur fracture (open injury leading to below-knee amputation) were followed up for 5 years (2003-2008).After the fracture site was exposed and freshened, a 45-degree (Figure 1) tongue-shaped tower end was created at the proximal end of the distal fragment using an oscillating saw (Figure 2). On the distal part of the proximal end a corresponding 'groove' was made. Dynamic compression plating for humerus and intramedullary nailing for femur was used (Figures 3 and 4) with appropriate early postoperative mobilisation.
