A Standing Percutaneous Technique for Proximal Interphalangeal Joint Arthrodesis in Twelve Horses (2014-2017).

The research article discusses a minimally invasive surgery technique for treating osteoarthritis in horses, and records its efficiency based on clinical outcomes in twelve horses. The results showed that a majority of the horses were able to perform at the level of activity as before, if not higher.

Methodology

• The researchers conducted a review of medical records and radiographs of horses that were diagnosed with osteoarthritis in the proximal interphalangeal joint.
• The treatment for these horses was a standing pastern arthrodesis using transarticular screws. This is a procedure in which the joint is fused, restricting motion, but providing pain relief for the affected animal.
• Outcome determination was accomplished via phone interviews with the horse owners, to understand the effects post-treatment.

Results

• The study comprised of 12 horses (15 limbs). The degree of osteoarthritis was severe in 80% of the cases and moderate in 20% of the cases.
• Follow-up was available for 13 limbs (87% of the total cases). According to the owners, about 73% of the horses were able to perform at their previous level of activity or higher post-surgery.
• There were two instances of horses remaining lame, and one that developed a surgical site infection and had to be put down.
• The average recovery time for the horses to return to their previous level of activity was 6.5 months, however, the recovery period varied from 1 to 18 months.

Conclusions

• The research concludes that the stabilization of the proximal interphalangeal joint in horses diagnosed with moderate to severe osteoarthritis can be effectively done using this standing technique.
• The procedure can be performed safely and provides similar outcomes compared to other techniques.
• While most horses could return to their prior level of activity, the results also highlight potential risks such as continued lameness and surgical infections, signaling the need for careful post-operative care.
