Three separate studies that collectively represent 107 dogs and 52 cats with supracondylar femoral fractures are presented. The animals were treated using a normograde intramedullary pinning technique at the Norwegian School of Veterinary Science during the period 1964 to 1993. The surgical technique involves insertion of one or two intramedullary pins normograde from the stifle joint without passing their proximal end proximal to the level of the femoral neck. The results of treatment were obtained for 73 dogs and 39 cats. Of these cases, 58 dogs (79.5 per cent) and 32 cats (82.1 per cent) were found to be free of lameness after the completion of treatment. Differences in the results of treatment, based on species or size, were not found. Of all cases in which the results of treatment were known (n = 112), complications were recorded in nine animals (8.0 per cent). Infection and instability were the most common complications, affecting four and three cases, respectively.
