Figure 6-7. Carpus and distal joints of equine thoracic limb. (A) Limb in flexion. Most of the carpal
flexion derives from flexion at radiocarpal and midcarpal joints; the carpometacarpal joint has little
movement. (B) Lateral view of equine thoracic limb in weight‐bearing position. (C) Dorsal view of the
equine carpus. (D) Dorsal view of the bovine carpus. The small first tarsal bone lies on the lateropalmar
side of the joint and cannot be seen in this dorsal view. A, accessory carpal; I, intermediate carpal; MC,
metacarpal; R, radial carpal; U, ulnar carpal.
