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.
