Minimally invasive arthroscopic-assisted reduction with TightRope® in a dog with coxofemoral luxation.

Received: Revised: Accepted: September 29, 2013 November 22, 2013 December 23, 2013 An American Cocker Spaniel was referred for repair of a left coxofemoral luxation (CL). On physical examination, the patient showed intermittent, non-weight-bearing lameness and pain. Radiographs revealed a craniodorsal coxofemoral joint luxation. To correct the coxofemoral luxation, Minimally invasive arthroscopic-assisted reduction (MIAR) with toggle pin fixation (Mini TightRope) was applied. A cranial lateral approach (incision <5 cm) to the coxofemoral joint was used. The torn round ligament of the femoral head was debrided under arthroscopy and no cartilage damage was found. The Suture-Button Kit was guided through the femoral bone tunnel to the pelvic cavity of the acetabulum under fluoroscopy and arthroscopy. At 3 months postoperatively, the patient showed normal ambulatory function without lameness. Coxofemoral joint luxation was corrected and stabilized successfully. MIAR with toggle pin fixation (Mini TightRope) can be used for CL in veterinary orthopedics. This minimally invasive technique may reduce operative complications and postoperative morbidity. ©2013 PVJ. All rights reserved
