Experimental study in dogs Bruno W Minto1 Cláudia Valeria S Brandão1 Gilberto JC Pereira2 Daniela Campagnol1 Maria Jaqueline Mamprim1 Carlos Roberto Padovani3 and José JT Ranzani1 Abstract 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. Keywords Dog hip total hip prosthesis hybrid system modular system Background Total hip arthroplasty THA is a common method of therapy for osteoarthrosis of the canine coxofemoral joint worldwide 1-4 . The main cause of coxofemoral ostearthrosis in dogs is hip dysplasia. This orthopedic disease is the most important cause of hindlimb lameness pain and reduced quality of life in dogs 5 6 . Among the various treatments for hip dysplasia THA stands out owing to its high success rate regarding alleviation of pain and restoration of hip function 7 . Only a few studies on THA have been accomplished in Brazil especially because of difficulties involving importation of implants and lack of .
