Suspensory Ligament Injuries

By Garrett Metcalf, DVM

The suspensory ligament is an important structure to the locomotion, soundness and support of the lower limb of a horse. It is a common tissue that can become injured acutely or sustain chronic injury over time that eventually causes lameness. Horse owners are typically aware of the suspensory ligament but don’t always understand the importance of the structure and what it does biomechanically for the horse. This article will cover anatomy, biomechanical function of the suspensory, types of injuries and treatment options.
