Isolated high median nerve injuries.

J A Boswick

    Bulletin of the Hospital for Joint Diseases Orthopaedic Institute
    |January 1, 1984
    PubMed
    Summary

    High median nerve injuries often involve brachial artery damage, leading to sensory loss and impaired thumb/index finger movement. Nerve repair successfully restored sensation, with motor function returning to forearm flexors within 6-13 months.

    Area of Science:

    • Neurology
    • Hand Surgery
    • Microsurgery

    Background:

    • High median nerve injuries frequently occur with brachial artery damage.
    • These injuries result in characteristic sensory deficits and motor impairments affecting the thumb and index finger.
    • Restoration of function after nerve injury is a significant clinical challenge.

    Purpose of the Study:

    • To evaluate the outcomes of nerve suture in high median nerve injuries.
    • To assess the recovery of sensibility and motor function following surgical repair.
    • To establish a timeline for functional recovery in the forearm flexors.

    Main Methods:

    • Surgical intervention involving nerve suture for high median nerve injuries.
    • Clinical assessment of sensory recovery based on nerve innervation patterns.
    • Monitoring of motor function, specifically the return of action in forearm flexors.

    Main Results:

    • Nerve suture consistently restored a degree of sensibility.
    • Motor function loss affected the interphalangeal joint of the thumb and index finger.
    • Forearm flexor muscle function returned predictably between 6 and 13 months post-suture.

    Conclusions:

    • Nerve suture is an effective treatment for high median nerve injuries, restoring sensation.
    • Functional recovery, particularly motor function in forearm flexors, follows a predictable timeline after surgical repair.
    • Understanding these recovery patterns aids in patient management and surgical planning for median nerve injuries.
