Thumb injuries in downhill skiing

O Engkvist, B Balkfors, U Lindsjö

    Summary
    This summary is machine-generated.

    Thumb injuries, often affecting the ulnar collateral ligament, are common in downhill skiing. Ski pole design, particularly large top plates, may increase thumb injury risk during falls.

    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Biomechanics

    Background:

    • Thumb injuries are a significant concern in downhill skiing, second only to knee injuries.
    • Ulnar collateral ligament (UCL) lesions of the metacarpophalangeal joint account for a substantial proportion of these thumb injuries.

    Purpose of the Study:

    • To investigate the relationship between ski pole design and the incidence of thumb injuries in downhill skiers.
    • To identify specific ski pole features that may mitigate or exacerbate thumb injury risk.

    Main Methods:

    • A case-control study comparing injured skiers with a control group of uninjured skiers.
    • Analysis of injury data to determine the frequency of thumb injuries and their association with different ski pole handle types.

    Main Results:

    • No current ski pole handle design completely eliminates the risk of thumb injury.
    • Ski pole handles with larger top plates were associated with a higher frequency of thumb injuries.
    • The method of gripping the ski pole, including strap usage, did not significantly influence thumb injury occurrence.

    Conclusions:

    • Skiers may retain their grip on ski poles during falls, leading to the pole acting as a fulcrum.
    • This mechanism can force the thumb into hyperextension and abduction, causing UCL injuries.
    • Further research into ski pole design modifications to reduce thumb injury risk is warranted.
