Management of Primary Injuries of the Medial Collateral Ligament of the Carpus in Two Horses

This case report describes the successful management of two horses with medial carpal collateral ligament injury. This is a rare cause of forelimb lameness and existing reports indicate a poor prognosis for return to athletic function with conservative management. Both horses were treated with a combination of box rest with controlled exercise and high-intensity laser therapy (HILT). Both horses returned to previous athletic function, one at Grand Prix level dressage and one at Novice level eventing. With appropriate management, the prognosis for carpal collateral ligament injury may be good. From this report, it is unclear whether a rehabilitation program including HILT offers improved prognosis compared with a rehabilitation program alone.
