Clinical, Radiological and Computed Tomographic Evaluations of the Effect of Triple Pelvic Osteotomy for Treatment of Canine Hip Dysplasia

Triple pelvic osteotomy (TPO) is one of the main surgical procedures to prevent or modify the progress of degenerative joint disease (DJD) related with hip dysplasia in young dogs. The aim of this study was to evaluate the effects of TPO in dogs. In this study, TPO were performed in 7 dysplastic cross-breed dogs in different gender (6 female and 1 male) and body weight (13.42±2.29 kg). In all cases, 20 degrees canine TPO plates were used. Before the operation, all cases were examined clinical, radiological and by computed tomographic. Postoperative 2nd and 6th weeks dogs were examined clinical, radiological and by computed tomographic and after 6 month both clinical and radiological examinations were performed. The joint laxity decreased 2 weeks after the operation. Dogs could walk on the treated leg after 2 weeks. The joint laxity decreased 2 weeks after the operation. Postoperatively dogs could walked on the treated leg after 2 weeks. The postoperatively measured Norberg angles (P<0.01) and acetabular anteversion angle (P<0.05) were significantly higher and distance between caput femoris and acetabulum was significantly lower (P<0.05) than preoperatively measurements. So, contact surface between the femoral head and the acetabulum had increased and the subluxation had disappeared. In radiographs obtained 6 months later, degenerative joint disease was not encountered. It was decided that canine hip dysplasia, could be treated successfully in young dogs via TPO, carried out before degenerative changes begin within the hip joints.
