    Summary
    This summary is machine-generated.

    Grade III rupture of the ulnar collateral ligament of the thumb, common in skiers, requires accurate diagnosis to prevent disabling symptoms. Metacarpophalangeal joint arthrogram is recommended over stress testing to avoid adductor interposition, guiding treatment with casting or surgery.

    Area of Science:

    • Orthopedic Surgery
    • Sports Medicine
    • Hand Surgery

    Background:

    • Ulnar collateral ligament (UCL) rupture, Grade III, is a frequent thumb injury, particularly in skiers.
    • Inadequate treatment can result in significant functional impairment and disability.
    • Historical diagnostic and treatment approaches have limitations.

    Purpose of the Study:

    • To outline historical diagnostic and treatment methods for Grade III UCL thumb ruptures.
    • To propose an improved diagnostic protocol to prevent iatrogenic adductor interposition.
    • To guide appropriate treatment selection based on diagnostic findings.

    Main Methods:

    • Review of historical diagnostic and treatment strategies for UCL thumb injuries.
    • Recommendation against vigorous clinical stress testing to prevent adductor interposition.

    Related Experiment Videos

  • Proposal of metacarpophalangeal joint arthrography as the preferred diagnostic tool.

    • Main Results:

    • Vigorous stress testing may inadvertently create adductor interposition, complicating diagnosis and treatment.
    • Metacarpophalangeal joint arthrography accurately establishes the diagnosis of UCL rupture.
    • Distinguishing between ruptures with and without adductor interposition is crucial for treatment planning.

    Conclusions:

    • Metacarpophalangeal joint arthrography is recommended for accurate diagnosis of Grade III UCL thumb ruptures.
    • Non-operative management (casting) is advised for ruptures without adductor interposition.
    • Surgical intervention (reduction and repair) is indicated for ruptures with adductor interposition.
