Radial, ulnar, and median nerve palsies caused by a congenital constriction band of the arm: single-stage correction.
Single-stage correction of a congenital constriction band of the arm in an infant with radial, ulnar, and median nerve dysfunction is reported with significant improvement in neurologic function. This was accomplished by thorough preoperative physical examination and neurologic evaluation, circumferential excision of the constricting band, decompression of the involved peripheral nerves, and multiple large Z-plasties for skin closure. Based on the case presented here and a review of the literature, management of patients with congenital constriction rings overlying major nerve trunks should include (1) complete neurologic examination, even in the infant, (2) electromyographic and nerve conduction studies if there is any evidence of nerve dysfunction, (3) early complete excision of the band in one stage if there is no evidence of edema seen with lymphatic or venous obstruction (otherwise, two-stage removal of the band should be planned), and (4) early exploration and decompression of all major peripheral nerves beneath the band if there is any neurologic dysfunction.
