Abstract
Objective This study is a case description of femoral neck lengthening and dorsal acetabular rim (DAR) arthroplasty to treat severe hip luxation in a 5-month-old male Cocker Spaniel (14.3 kg) and to compare the clinical outcome with that of contralateral femoral neck excision. Study design Case report. Results Femoral head coverage improved after surgery (preoperative lateralization of the centre of the femoral head with regard to the dorsolateral acetabular rim: 10 mm; postoperative lateralization of the centre of the femoral head: –1.3 mm). The postoperative Barden's test was negative. The dog was bearing weight 2 weeks postoperatively. Radiographic signs of bone healing were present at the 6-week follow-up examination. No complications were detected. Conclusions Femoral neck lengthening and DAR augmentation were performed in a growing dog affected by severe hip luxation and DAR insufficiency.
Highlights
Canine hip dysplasia is one of the most common orthopaedic conditions in the dog.[1,2] It is generally described as a developmental disorder, characterized by varying degrees of laxity of the hip joint, which leads to continued femoral head subluxation, shallow acetabulum, remodelling of the joint surfaces, osteoarthritis and pain.[1,2]This case report describes the surgical procedure and the clinical outcomes of unilateral femoral neck lengthening[3] combined with dorsal acetabular rim (DAR) augmentation,[4] performed in a juvenile dog affected by severe hip joint laxity
