Abstract
Coxofemoral luxation is a common orthopedic lesion in dogs. This study aimed to evaluate the effectiveness of a modified toggle splint with nylon suture as a prosthetic teres ligament for reducing and fixing coxofemoral luxation in dogs. Five adult mongrel dogs weighing 15±2 kg were used in this experimental study. The toggle splint was fabricated from a Steinmann pin (1cm length, 2mm diameter) by drilling 0.5 mm hole in the center. Stabilization of coxofemoral joint was performed by a modified Toggle splint technique. A tunnel, from the major trochanter through the fovea capitis to the acetabulum, was performed in which the toggle splint was passed through, and nylon suture was used for fixation. Dogs were scored for lameness severity at 0-, 14-and 42-day post-operation using a numerical rating scale (NRS) with 5 levels, and reductions were assessed radiographically at three-time points the day of operation, day 28th, and day 42nd. The results showed that the treatment splint was effective in achieving good reduction and fixation in four out of five (80%) dogs at all time points. Reluxation was observed only in one dog (20%) up to week 6 post-operation. The mean lameness score on day 14 (2.0±0.87) and 42 (0.60±0.60) were significantly lower (P<0.001) compared to day 0. These results indicate that the modified toggle splint with nylon suture is a promising treatment option for canine coxofemoral luxation.
