Arthroscopic removal of osteochondral fragments from the proximal interphalangeal joint of the pelvic limbs in three horses.

This research article discusses the use of arthroscopic surgery to successfully remove osteochondral fragments from the proximal interphalangeal joint in the pelvic limbs of three horses, which led to alleviation of lameness and joint enlargement.

Study Summary

• Three horses, two Standardbreds and one Thoroughbred, exhibited joint enlargement and lameness. The cause was identified to be osteochondral fragments in the proximal interphalangeal joint of their pelvic limbs.
• These fragments were removed through an arthroscopic procedure, which involved the use of an arthroscope, a type of endoscope that is inserted into the joint through a small incision.
• Accurate placement of the arthroscope into the dorsal joint space was found to be crucial in gaining a clear view of the fragments, thereby allowing for successful extraction.

Post-Operative Results

• After the surgery, there was a marked improvement in the condition of the horses. Two of them were able to return to racing without any joint problems, and the third one was in training to race.

Diagnostic Importance

• The study emphasized the importance of high-detail radiographs in the detection of osteochondral fragments in horses showing symptoms such as joint enlargement or lameness.
• Hence, in order to manage lameness in horses effectively, it is essential to diagnose the cause accurately, and in cases such as this, radiography plays a vital role.
