Diagnostic Ultrasound & Musculoskeletal Injuries in Horses
Anatomy of the Forelimb
The majority of equine tendon and ligament injuries occur in the metacarpal (foreleg), metatarsal (hind leg) and pastern regions. The superficial digital flexor tendon (SDFT) and suspensory ligament (SL) are the most commonly affected structures. The SDFT is located just under the skin surface, followed by the deep digital flexor tendon (DDFT) , inferior check ligament and suspensory ligament. In the pastern region, the SDF and DDF tendons are also evaluated as well as the distal sesamoidean ligaments (straight and oblique) While this brochure focuses on these regions, the principles are similar for any musculoskeletal injury. Ultrasound can also be utilized to diagnose injuries in other areas such as the shoulder, stifle, fetlock, sacroiliac and pelvic region.
