 Tibia fractures are often part of the injuries in the polytrauma patient. Complicated fractures produced by trauma are often in the need for bone graft. Bone graft is usually obtained from the hip or the distal radius and the procedure is not exempt of complications such as pain, infection and increased hospitalization stay. In order to avoid these events, bone graft substitutes have been developed but most of them are expensive. 11 An example of this is bone morphogenic proteins BMPs. BMPs have shown a high efficacy rate but cost wise, they could be prohibitive. 11 DBM could be a reasonable alternative and tentatively could have the same efficacy and less antigenic risks 5,9,11. Previous well designed studies have demonstrated the efficacy of demineralized bone matrix in fracture healing of non-unions, total joint osteolytic lesions, benign bone cysts and spine fusions.3-9,11-13 It has even proved it potential efficacy in restoring cartilage surface 7. The importance of this findings support the idea of using DBMs in other applications that could beneficiate the trauma patient.
