Pathologic anatomy of the forearm: intersection syndrome.

A B Grundberg, D S Reagan

    The Journal of Hand Surgery
    |March 1, 1985
    PubMed
    Summary

    Intersection syndrome, a common forearm condition, causes pain where specific forearm muscles cross wrist extensors. Operative treatment reveals stenosing tenosynovitis as the primary pathology.

    Area of Science:

    • Orthopedics
    • Anatomy
    • Pathology

    Background:

    • Intersection syndrome is a frequent cause of forearm pain, often misdiagnosed.
    • Symptoms include pain and swelling at the intersection of forearm muscles and wrist extensors.
    • The exact cause remains unclear.

    Purpose of the Study:

    • To investigate the underlying pathology of intersection syndrome.
    • To evaluate operative treatment outcomes for this condition.

    Main Methods:

    • Operative treatment was performed on 13 patients with intersection syndrome.
    • Surgical findings were analyzed to determine the basic pathologic abnormality.

    Main Results:

    • The primary pathological finding in operative cases was stenosing tenosynovitis.
    • This tenosynovitis affected the sheath of the common radial wrist extensors.

    Conclusions:

    • Stenosing tenosynovitis of the common radial wrist extensor sheath is the fundamental pathology in intersection syndrome.
    • Surgical intervention can address this condition.
