Matched distal ulnar resection.

H K Watson, J Y Ryu, R C Burgess

    The Journal of Hand Surgery
    |November 1, 1986
    PubMed
    Summary

    A matched resection arthroplasty for distal radioulnar joint pain preserves key structures, offering reliable pain relief and improved hand function. This surgical technique maintains normal joint alignment and restores painless wrist rotation.

    Area of Science:

    • Orthopedic Surgery
    • Hand Surgery
    • Musculoskeletal Disorders

    Background:

    • Distal radioulnar joint (DRUJ) disorders significantly impair hand function and work capability.
    • Traditional Darrach transverse resection of the distal ulna has been the standard treatment.
    • Limitations of the Darrach procedure include potential instability and altered joint mechanics.

    Purpose of the Study:

    • To evaluate the efficacy and outcomes of a "matched" resection arthroplasty technique for DRUJ disorders.
    • To assess pain relief, functional recovery, and joint alignment preservation following this surgical approach.

    Main Methods:

    • A retrospective study of 44 wrists treated with "matched" resection arthroplasty.
    • This technique preserves the ulnar shaft-styloid axis, triangular fibrocartilage complex, and ligamentous attachments.
    • The distal ulna is resected in a convex curve to match the concave radial metaphysis.

    Main Results:

    • The procedure demonstrated reliability in relieving pain associated with DRUJ disorders.
    • Patients experienced significant restoration of painless pronation (average 80.5 degrees) and supination (average 88.5 degrees).
    • The technique maintained more normal ulnocarpal, radioulnar, and radiocarpal alignment over an average 6.5-year follow-up.

    Conclusions:

    • Matched resection arthroplasty is an effective treatment for painful distal radioulnar joint disorders.
    • The technique offers a reliable method for pain reduction and functional restoration of the wrist.
    • Preservation of anatomical structures leads to improved joint alignment and range of motion.
