An Uncommon Presentation of Constriction Band Syndrome: A Case Report and Review of Literature

    https://doi.org/10.1142/S2424835522720419Cited by:0 (Source: Crossref)

    One of the rarer manifestations of constriction band syndrome (CBS) is peripheral nerve palsy. We report a 6-year-old child presenting with motor deficits of the median, ulnar and radial nerves and atrophy of the biceps and brachialis atrophy due to CBS. We were unable to find any similar reports in the literature. He had a constriction ring at the upper arm that had undergone multiple z-plasty by another surgeon. On examination, he had medical research council (MRC) grade 1 elbow flexion, weak flexion of fingers and absent extension of fingers and wrist. We used a pedicled pectoralis major myocutaneous flap to restore elbow flexion and the patient achieved M4 flexion of the elbow.

    Level of Evidence: Level V (Therapeutic)
