Description: A fracture of the sesamoid bone(s) at the back of the fetlock joint. Sesamoid Fracture


Cause: Often occur at the end of a race or work-out when the horse is fatigued.


Treatment: Depends on the location of the fracture. Fractures or chips at the top of the sesamoids are easiest to repair by surgery.  Some of these cases can return to a moderate riding without surgery.  Middle fractures normally need to be repaired with a screw. A fracture or chip at the bottom of the sesamoid is the worst and has the poorest prognosis.


Prognosis: Poor circulation to the sesamoids impedes healing. The suspensory ligament attaches to these bones and is often involved in the injury. The prognosis depends on the location of the fracture and amount of damage to the suspensory ligament. With or without surgery, most horses’ futures may be limited to lower level disciplines, however, some have been able to return without any limitations.
