Degenerative joint disease of the proximal interphalangeal joint was diagnosed in nine joints of six horses. All of the horses were 3 years old or younger and the affected joints were in the hindlimbs. Radiographic evidence of osteochondrosis involving the distal end of the proximal phalanx was apparent in five joints. Lameness and local soft tissue swelling were prominent in all cases. In one horse killed because of lameness, histological examination of joint tissues revealed osteochondrosis as well as severe osteoarthritis. Surgical arthrodesis of the affected joint was performed on two horses, one of which became sound.
