Clinical and biomechanical evaluation of transfixation device developed for bovine fracture management

A transfixation cast made up of a couple of intramedullary Steinmann pins, a pair of plywood plans (9 mm) and plaster of Paris (five layers) was developed for clinical application for the management of tibial fractures in bovine. Six of such fabricated models were tested for axial compression and another six were subjected for three-point bending. In vitro yielding and failure loads (axial compression) and failure bending load (three-point bending) of the models were evaluated. The radiolucency of construct was also evaluated in the patient. Compressive stress of the transfixation cast was found to be (Mean±SE) 3.482±0.182 N/mm² and bending stress of the transfixation cast was found to be (Mean±SE) 5.534±0.233 N/mm². This construct was applied for the repair of six cases of tibial fracture in bovine of which one was compound in nature. The construct was clinically found to be patient friendly for the treatment of bovine tibial fracture.
