Summary

A new endoscopic technique was developed to divide the annular ligament in horses. This minimally invasive approach successfully treated complex tenosynovitis, with most horses returning to athletic soundness.

Area of Science:

  • Veterinary Surgery
  • Equine Orthopedics
  • Minimally Invasive Techniques

Background:

  • Complex tenosynovitis in horses often involves the annular ligament.
  • Surgical intervention is sometimes required for treatment.
  • Minimally invasive techniques offer potential benefits over traditional surgery.

Purpose of the Study:

  • To develop and evaluate an endoscopically assisted technique for annular ligament division.
  • To assess the safety and efficacy of this technique in horses with tenosynovitis.

Main Methods:

  • A novel technique using a slotted cannula and arthroscopic visualization was developed.
  • The procedure was tested on cadaver limbs and then applied to seven horses with tenosynovitis.
  • Tenoscopic examination and adhesiolysis were performed prior to ligament transection.

Main Results:

  • Complete division of the annular ligament was confirmed arthroscopically and post-mortem in cadavers.
  • In horses, the technique successfully treated tenosynovitis, adhesions, and bands.
  • Five of seven horses became sound athletes without recurrence; one had residual lameness, and one was convalescing.

Conclusions:

  • Endoscopically assisted annular ligament transection is a safe and effective treatment for complex equine tenosynovitis.
  • This minimally invasive technique can lead to successful return to athletic function.
  • Further studies may explore long-term outcomes and broader applications.
