in simplest terms the suspensory ligament originates at the back of the knee and runs down to the fetlock where it splits into two branches that attach to the outside surface of the sesamoid bones and the 2 branches continue down the pastern to connect to the flexor tendon between the pastern and the foot. it's function is to support the fetlock during the weight bearing phase of stride. It's a big deal and rarely heals well enough to return to the same condition....as scarring at the injury site leads to rigidity where it needs to be supple. My horse has an old lateral branch injury I wish I had a scanner so I could post his ultrasound scan pictures....you can really see the thickening and scarring.
