An arthroscopic approach to the palmaroproximal or plantaroproximal pouch of the distal interphalangeal joint was developed in six cadaver limbs and seven limbs of three clinically normal horses. The dorsal aspect of the proximal border and the proximal articular margin of the distal sesamoid (navicular) bone, the palmar aspect of the distal articular margin of the middle phalanx, the collateral sesamoidean ligaments of the distal sesamoid bone, and the joint capsule attachments were readily accessible. Distending the joints with fluid gave access to portions of the articular surface between the distal sesamoid bone and the middle phalanx in all joints, and to a small portion of the distal phalanx in two hind distal interphalangeal joints. Two horses allowed to recover from anesthesia were not lame on days 30 and 37, respectively. Problems encountered initially were difficulty entering the joint, hemarthrosis, and minimal iatrogenic cartilage damage.
