The suspensory ligament runs down the back of the cannon bone from just below the knee (or hock). Its job is to support the ankle joint as it sinks under weight and returns to normal when the weight comes off.
The deep digital flexor tendon runs down the back of the leg and behind the heel to attach to the bottom of the coffin bone. Its main job is to flex the leg, but it also plays a support role at the heel, where the tendon fibres fan out to pass over the navicular bone.
Sport horses can bruise bones in the foot and ankle joints, the coffin bone, the ends of the short and long pastern bones and the lower end of the cannon bone. The foot and ankle come under tremendous force and that force is focused on the small areas where these bones meet.
Acute synovitis is inflammation that appears suddenly in a joint, often the ankle, coffin or hock. These joints are enclosed in a capsule of soft tissue; the capsule lining (synovial membrane) produces a thick fluid that lubricates the joint. Stress on the joint can trigger inflammation in the lining and the capsule, causing fluid to turn watery and build up. Over time, repeated joint stress can set off a destructive chain of events that lead to osteoarthritis.

Work strengthens muscles, but overwork leads to strain and pain. The large muscles of the back and hindquarters make up a sport horse's drive train, and they can be strained if asked to work too hard for too long. Most muscle strains are mild and the amount of damage is small, but this is a common injury, and it can be enough to keep your horse from performing his best.
