Arthrodesis of the equine centrodistal and tarsometatarsal joints using a single modified kerf-cut cylinder.
Abstract: To describe a technique for surgical placement of a modified kerf-cut cylinder for the purpose of arthrodesis across the equine centrodistal and tarsometatarsal joints. Methods: Each horse (n = 4) underwent unilateral placement of a single kerf-cut cylinder spanning the centrodistal and tarsometatarsal joints with the placement of an autologous cancellous bone graft. Horses were evaluated via lameness examination and radiography postoperatively and euthanatization of each horse was performed at four different time points up to 12 weeks post-surgery to evaluate for lameness, implant stability and success with integration in the surrounding bone. Results: Implants were placed successfully in three of four horses. In one horse, due to technical error, the implant was misaligned with the joint spaces. Although the horse exhibited minimal pain, it was euthanatized at the two week follow-up. Implant placement in the remaining three horses was successfully achieved. At eight weeks, radiographically there was evidence of osseous union across the joint spaces. No change in lameness was detected at any point after surgery. At 12 weeks post-surgery, histologically the implants were filled with mineralized osteoid and demonstrated integration with the surrounding tissue. Conclusions: The surgical approach and placement of modified kerf-cut cylinders for arthrodesis of the centrodistal and tarsometatarsal joints were successfully achieved with minimal signs of postoperative pain and a short rehabilitation time period in normal horses.

The research studied a new surgical method for arthrodesis across two joints in horses, using a modified kerf-cut cylinder. The technique showed successful results with minimal postoperative pain and a short rehabilitation period.
Research Method
- The method entailed surgically placing a single modified kerf-cut cylinder to bridge the centrodistal and tarsometatarsal joints of the horses’ legs. An autologous cancellous bone graft was used alongside.
- The sample size was four horses who underwent this surgery unilaterally.
- Post-surgery, horses were checked with lameness examination and radiography at four stages up to 12 weeks. Signs of lameness, stability of the implant, and its integration within the surrounding bone were all monitored.
Research Findings
- In three out of the four horses, the implants were successfully placed. The failed attempt was due to a technical error resulting in misalignment with joint spaces, leading to the euthanization of the horse at 2 weeks.
- Eight weeks post-surgery, there was radiographic evidence of osseous union across the joint spaces in the three successful cases. There was no recorded change in lameness throughout the follow-ups.
- By the 12-week mark, the implants were filled with mineralized osteoid and showed signs of integration with the surrounding tissue, as observed histologically.
Research Conclusion
- The modified kerf-cut cylinder method for arthrodesis was proven successful in the centrodistal and tarsometatarsal joints of horses.
- Even though a case of technical error is reported, generally the technique exhibited minimal signs of post-operative pain and comparatively reduced rehabilitation time.
