Every year thousands of foals are born with flexural and angular limb deformities or deviations at the level of the fetlock and or the carpus, avoiding that they reach their top performance level later in their future or at the sales. Most of these problems could be avoided if they are assisted correctly at an early age. Traditionally many home made devices have been used like PVC pipes and casts, with the disadvan-age that they injure or leave skin marks in the foal’s legs.
