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 2 nd and 6 th 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.

Bu çalışmanın amacı, köpeklerde TPO'nun 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<0.01) ve asetabular antreversiyon açısı (P<0.05) preoperatif değere göre yüksekti ve kaput femoris ve asetabulum arasındaki mesafe belirgin olarak düşük bulundu. Bu nedenle, asetabulum ve kaput femoris arasındaki temas yüzeyi artarak, subluksasyon kayboldu. Altı ay sonra elde edilen radyografilerde, dejeneratif eklem hastalığına rastlanmadı. Kalça displazili genç köpeklerde kalça eklemi...

“…Two lines were then drawn perpendicular to this line: one at the lateral aspect of the dorsal acetabular rim and one at the medial aspect of the femoral head [4,8,11]. The lateral center edge angle was defined as the angle determined by the dorsal edge of the acetabulum, the center of the femoral head, and a horizontal line on CT images [1,6]. The center distance (CD) index was calculated as the distance between the center of the femoral head and the center of the acetabulum, divided by the measured radius of the femoral head (Fig.…”

Laxity of Canine Hip Joint in Two Positions with Computed Tomography

ABSTRACT. Computed tomographic (CT) examination of 20 canine hip joints was carried out in two positions, normal-standing and weightbearing. In normal (dorsal acetabular rim angle: DARA < 15°) or slightly abnormal (DARA, 15° to 20°) hip joints, the values of parameters to laxity were evaluated as more severe in the weight-bearing position. Comparisons of results using various indicators, including the center distance (CD) index, dorsolateral subluxation score, and lateral center edge angle, revealed that the CD index may be a useful marker of functional laxity in the canine hip joint under CT scanning. Further, CT scanning in the weight-bearing position was more sensitive than in the normal-standing position for the detection of laxity in hips with normal or only slightly abnormal DARA.
