A four year old, Thoroughbred mare presents for lameness in the left front leg of several weeks duration. At physical examination, there is very mild swelling along the dorsum of the metacarpus. Deep palpation of this region is moderately painful. Lameness is not evident at the walk but is mild after trotting. Radiographs of the metacarpus were taken.
