Summary
This study shows that using two parallel 5.5-mm cortical bone screws for proximal interphalangeal joint arthrodesis in horses is highly successful. This surgical technique for pastern arthrodesis results in over 85% successful outcomes for horses.
Area of Science:
- Equine surgery
- Orthopedic surgery
- Veterinary medicine
Background:
- Proximal interphalangeal joint (PIJ) injuries are common in horses.
- Surgical arthrodesis is a treatment option for PIJ lameness.
- Effective surgical techniques are crucial for successful outcomes.
Purpose of the Study:
- To evaluate the clinical outcomes of PIJ arthrodesis in horses.
- To assess the efficacy of using two parallel 5.5-mm cortical bone screws in lag fashion for PIJ arthrodesis.
- To determine factors influencing surgical success.
Main Methods:
- Retrospective study of 34 horses undergoing PIJ arthrodesis.
- Screws: two 5.5-mm ASIF cortical bone screws, parallel, lag fashion.
- Outcome criteria: return to previous level of function or athletic use.
Main Results:
- Successful outcome in 85% of frontlimbs and 89% of hindlimbs.
- Overall success rate of >85% for PIJ arthrodesis.
- Complications were infrequent and mostly unrelated to the surgical procedure.
Conclusions:
- Arthrodesis of the PIJ using two parallel 5.5-mm screws is effective.
- The technique provides a high success rate for restoring athletic function.
- Shortened postoperative coaptation is associated with successful outcomes.
