title: Innervated thenar pedicle flap with the palmar cutaneous branch of the median nerve for treating a thumb pulp defect: a case report.
abstract: A 51-year-old male plumber with a thumb pulp defect was treated with a reversed innervated thenar pedicle flap. The flap was based on the radial digital artery originating from the princeps pollicis artery with the palmar cutaneous branch of the median nerve. The flap survived and achieved good innervation with a moving 2-point discrimination of 6 mm at 12 months after surgery. This flap is indicated for patients who hesitate to have tissue taken from the foot. We believe that this flap is a feasible option for reconstructing thumb pulp defects.
