"Normal" talar tilt angle.

    Summary
    This summary is machine-generated.

    Normal talar tilt is minimal in healthy ankles without prior injury. A talar tilt exceeding 5 degrees on stress roentgenograms in young adults likely indicates significant lateral ankle ligament damage.

    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Radiology

    Background:

    • Assessing normal talar tilt is crucial for diagnosing ankle injuries.
    • Previous studies have not definitively established normal talar tilt ranges in healthy young adults.

    Purpose of the Study:

    • To determine the degree of normal talar tilt in individuals without a history of ankle injuries.
    • To establish baseline talar tilt measurements for healthy ankles.

    Main Methods:

    • Manual inversion stress roentgenograms were performed on 404 ankles from 202 healthy U.S. Naval Academy midshipmen.
    • Participants had no history of ankle trauma.

    Main Results:

    • Only 9.7% of ankles exhibited measurable talar tilt.

    Related Experiment Videos

  • A mere 1.7% of ankles showed a talar tilt greater than 5 degrees.
  • Normal talar tilt does not extend to 23 degrees.

    • Conclusions:

    • Healthy ankles in young adults with no trauma history rarely demonstrate significant talar tilt.
    • A talar tilt over 5 degrees in this population strongly suggests injury to lateral ankle supporting structures when evaluated with stress roentgenograms.
