Clinical, radiological and computed tomographic evaluations of the effect of triple pelvic osteotomy for treatment of canine hip dysplasia

Triple pelvik osteotomi (TPO) genç köpeklerde kalça displazi ile ilgili dejeneratif eklem hastalığı (DJD)nın ilerlemesini önlemek ve değiştirmek için uygulanan cerrahi bir işlemdir. Bu çalışmanın amacı, köpeklerde TPOnun etkilerini araştırmaktır. Bu çalışmada, farklı cinsiyet (6 dişi, 1 erkek) ve vücut ağırlığındaki (13.42±2.29 kg) displazik 7 köpekte TPO yapıldı. Bütün olgularda, 20º canin TPO plağı kullanıldı. Operasyon öncesi tüm olguların klinik, radyolojik ve bilgisayarlı tomografi ile muayeneleri yapıldı. Köpekler operasyon sonrası 2. ve 6. haftalarda klinik, radyolojik, bilgisayarlı tomografik muayene ve 6 ay sonra hem klinik hem de radyolojik muayeneleri yapılarak takip edildi. Operasyondan 2 hafta sonra eklem gevşekliği azaldı. Köpekler operasyon sonrası 2 haftada tedavi edilen bacakları üzerinde yürüyebiliyorlardı. Postoperatif ölçülen Norberg açıları (P

Köpeklerde kalça displazisinin sağaltımında triple pelvik osteotomi etkilerinin klinik, radyolojik ve bilgisayarlı tomografi ile değerlendirilmesi

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.
