The tough hoof capsule protects sensitive structures within and allows the natural horse to gallop over dry, rocky terrain with apparent impunity. Equids are normally mobile and athletic but when they develop laminitis and become crippled we realise,belatedly, how dependent they were on an intact, functional, pain-free suspensory apparatus of the distal phalanx (SADP). We have evaluated the effect of cooling the distal limb of horses by continuously applying very cold water to the lower limbs of horses (Pollitt and van Eps 2004; Van Eps and Pollitt 2009). Horses were stood in a circulating cold water bath for 72 h. Thus all 4 limbs were subjected to continuous cryotherapy and when removed from the water bath the horses were observed for 4 days. There was mild transient oedema of the distal limbs but no lameness or skin damage. Histological examination of hoof wall lamellae, taken 7 days after cryotherapy commenced, showed no lesions. No adverse clinical effects were noted in the cooled limbs up to one year following cessation of the cryotherapy.
