Dissection of plantar aspect of left foot
Nerve supply to dorsal interosseous muscles; interior of first metatarsophalangeal joint
The plantar interossei have been detached and removed from the dissection to provide a better view of the dorsal interossei and their nerves. In addition, the capsule of the first metatarsophalangeal joint has been opened by a wide incision to expose the interior of the joint.
