Fractures of the Distal Phalanx in 72 Racehorses: 1990-2001

Fractures of the equine distal phalanx may be a form of stress-related bone injury much like other stress fractures in the racehorse. Early scintigraphic examination of racehorses with palmar foot pain may identify stress-related bone injury before fracture and allow corrective shoeing to be instituted. These fractures most commonly occur in the lateral aspect of the left forelimb and the medial aspect in the right forelimb. Despite the fact that this injury can lead to osteoarthritis of the distal interphalangeal joint, there is a favorable prognosis for return to racing.
