Sumario:BACKGROUND: This prospective experimental study evaluated the surgical procedure and results of modular hybrid total hip arthroplasty in dogs. METHODS: Ten skeletally mature healthy mongrel dogs with weights varying between 19 and 27 kg were used. Cemented modular femoral stems and uncemented porous-coated acetabular cups were employed. Clinical and radiographic evaluations were performed before surgery and at 30, 60, 90, 120, 180 and 360 days post-operation. RESULTS: Excellent weight bearing was noticed in the operated limb in seven dogs. Dislocation followed by loosening of the prosthesis was noticed in two dogs, which were therefore properly treated with a femoral head osteotomy. Femoral fracture occurred in one dog, which was promptly treated with full implant removal and femoral osteosynthesis. CONCLUSIONS: The canine modular hybrid total hip arthroplasty provided excellent functionality of the operated limb.
