Pedicled Instep Flap and Tibial Nerve Reconstruction in a Cynomolgus Monkey [Macaca fascicularis]

Abstract EN

A male cynomolgus monkey experienced extensive soft tissue trauma to the right caudal calf area.

Some weeks after complete healing of the original wounds, the monkey developed a chronic pressure sore on plantar surface of the heel of its right foot.

A loss of sensitivity in the sole of the foot was hypothesized.

The skin defect was closed by a medial sensate pedicled instep flap followed by counter transplantation of a full thickness graft from the interdigital webspace.

The integrity of the tibial nerve was revised and reconstructed by means of the turnover flap technique.

Both procedures were successful.

This is an uncommon case in an exotic veterinary patient as it demonstrates a reconstructive skin flap procedure for the treatment of a chronic, denervated wound in combination with the successful reconstruction of 2.5 cm gap in the tibial nerve.
