Radiographic studies on influence of polymethylmethacrylate on femur fracture healing in dogs

The study was conducted in 12 clinical cases of femur diaphyseal fractures in dogs, which were presented for treatment. The animals were randomly divided into two groups of six animals each (group A and group B). In dogs of group A, the femur diaphyseal fractures were repaired by retrograde intramedullary pinning technique with cerclage wiring. In dogs of group B, femur diaphyseal fractures were repaired by intramedullary pinning, and gentamicin impregnated polymethyl-methacrylate was used as a luter in the form of small splints, placed on the medial and lateral aspect of the fracture site and secured with cerclage wire. The radiographic studies undertaken on days 0, 1, 15, 30, 45 and 60 revealed better healing of femoral fracture treated with gentamicin impregnated polymethyl-methacrylate splints than with conventional intramedullary pinning and cerclage wiring.
