Reconstruction of Severe Palm Injury with Sensate Medial Plantar Artery Flap and Nerve Grafting

Abstract

Summary:. A 28-year-old, healthy man presented with an abrasion injury of the left palm, including a full-thickness glabrous skin defect, an open injury of the carpal tunnel with 50% transection of the median nerve, and a multilevel traction/avulsion injury of the thenar motor branch. He underwent repair with a free medial plantar artery flap, nerve transfer of the palmar cutaneous nerve to the medial plantar cutaneous nerve, grafting of the median nerve, and direct neurotization of the thenar muscles via an end-to-side nerve graft from the median nerve. At 8 months postoperative, both donor and recipient areas had healed completely, and the patient had regained meaningful 2-point discrimination of the palm and fingers, achieved innervation of the thenar muscles, and returned to work as a cook.
