Ilial crest bone graft transposition as treatment for fracture of the medial femoral trochlear ridge in a dog

This is a report of a fracture of the medial trochlear ridge of the distal femur occurring as a major complication after surgery for medial patellar luxation. To address the complication, a non-vascularized iliac bone graft was collected and fixated with two positional screws to the trochlea. An external skeletal fixator was placed to prevent motion of the stifle joint during the healing period and to reduce the risk for fragment dislodgment. One year after the graft was placed the dog's function was satisfactory. This case report indicates that a non-vascularized iliac bone graft provides an alternative for management of fractures of the medial ridge of the distal femur.
