Luxation of the metacarpophalangeal and metatarsophalangeal joints in horses.

Abstract

Lateral or medial luxation of the metacarpophalangeal or metatarsophalangeal (fetlock) joint in 10 horses is presented. Closed and open fetlock luxation each occurred in five horses. Horses were treated by cast immobilisation after debridement of soft tissue and joint lavage in cases of open luxations. Suture apposition of a ruptured collateral ligament was attempted in three cases. Antibiotic therapy was used in all cases of open fetlock luxation but non-steroidal anti-inflammatory medication was used inconsistently. Whether closed or open, fetlock luxations had a good prognosis for return to breeding status. After treatment, seven horses were used for breeding, one horse was ridden for nine years, one horse remained lame and was destroyed and one horse was lost to follow up.
