Bucked Shins in horses, also known as dorsal metacarpal sickness is a form of disease with young horses. Bucked shin happens when there is tearing of periosteum tissue which connects muscles to the cannon bone. The problem is common in young horses that take part in high speed races and trainings due to the fact that their bones are less developed and less dense unlike the mature horses. Therefore the bones are not strong enough to withstand the pressure during high speed performance.
Young thoroughbreds often experience this bucked shin disease mostly in the forelimbs and the injury can be bilateral and normally happens sequentially affecting the left leg first. SynNutra Equine strongly advises racehorse owners to closely monitor their horses and have understanding of proper nutrition that will ensure good development of bones. Diagnosis is basically by medical examination and history. Radiography helps in determining the level of periosteal reaction and whether there is stress fracture in the dorsal cortex. Taking rest from performance and altering the training schedules, according to SynNutra Equine, is important to have the inflammation heal.
