The callus formed due to splint bone injury can become large and put pressure on the suspensory ligament. Bone heals by formation of a callus over the defective area. Speed and quality of healing is directly related to the blood supply and fracture stability. Rest is required immediately following injury to reduce movement of the fracture site.
For example, racehorses are more likely to have fatigue-related injuries such as stress fractures and injury to the flexor tendons, while western show horses are more likely to have navicular syndrome and English sport horses are more likely to have osteoarthritis or injury to the suspensory ligament.

The size and position of this bony lump determine whether a splint is likely to cause long-term lameness. The lump can interfere with the knee joint or the suspensory ligament, which runs down the back of the cannon bone. [50] Splints force 7% of racehorses to retire. [47] Luxations are joint dislocations and account for 8% of fatal injuries.

Proximal check ligament desmotomy has been shown to return horses to work faster, but is thought by some to predispose to suspensory ligament injury. [citation needed] Mesenchymal stem cells, derived from the affected horse's bone marrow or fat are currently being used as a potential therapy for SDFT tendinitis and other injuries. [11] [12]
The prognosis for a horse with navicular syndrome is guarded. Many times the horse does not return to its former level of competition. Others are retired. Eventually all horses with the syndrome will need to lessen the strenuousness of their work, but with proper management, a horse with navicular syndrome can remain useful for some time.
Below the knee/hock, the tendon is superficial to the suspensory ligament, but deep to the SDFT. Fairly commonly injured by horses doing fast work, the DDFT is round in cross section. Superficial digital flexor : Runs down the back of the leg, behind the carpus and cannon, branches below the fetlock and inserts into the distal side of the 1st ...
Skeleton of the lower forelimb. Each forelimb of the horse runs from the scapula or shoulder blade to the third phalanx (coffin or pedal) bones. In between are the humerus (arm), radius (forearm), elbow joint, ulna (elbow), carpus (knee) bones and joint, large metacarpal (cannon), small metacarpal (splint), sesamoid, fetlock joint, first phalanx (long pastern), pastern joint, second phalanx ...
