Plain-English summary
In this study, two dogs and two cats were treated with total hip replacement after their previous surgery, called femoral head and neck excision, didn't work well. All the animals were suffering from severe hip pain and had trouble walking because the first surgery didn't fully remove the femoral neck or caused issues with the sciatic nerve. The veterinarians used different types of implants for the hip replacement, and despite some challenges during the surgery, all four pets showed good improvement afterward. They were able to return to normal activity within about 12 weeks, although one cat did need another surgery due to a complication with the implant. Overall, the treatment was successful in relieving pain and restoring mobility.
Abstract
OBJECTIVE: To document outcome in 2 dogs and 2 cats after conversion of femoral head and neck excision (FHNE) to total hip replacement (THR). STUDY DESIGN: Case series. ANIMALS: Dogs (n = 2) and 2 cats. METHODS: For 1 dog and 2 cats, THR was performed using cemented acetabular and femoral components. Noncemented acetabular and cemented femoral components were used in 1 dog. RESULTS: All animals presented with severe hip pain and chronic lameness after unsuccessful FHNE. Potential causes of suboptimal outcome after FHNE were incomplete resection of the femoral neck (n = 3) and fibrous adhesions involving the sciatic nerve (n = 2). Post-FHNE remodeling of the proximal femur and acetabulum necessitated unconventional modifications of surgical technique. In all 4 cases, final clinical outcome and radiographic reassessment were satisfactory. Aseptic loosening of the acetabular bone-cement interface necessitating surgical revision was the only complication noted in 1 cat. CONCLUSIONS: Despite severe preoperative pain and chronic functional impairment in all cases, conversion of FHNE to THR produced marked clinical improvement including return to unrestricted exercise within 12 weeks of surgery.
