    A survey of young baseball pitchers found elbow abnormalities in 20% of participants. Despite these findings, no direct links were established between pitching activity and elbow issues in this age group.

    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Pediatric Sports Medicine

    Background:

    • Youth baseball pitching places significant stress on the elbow joint.
    • Understanding the prevalence and causes of elbow abnormalities in young athletes is crucial for injury prevention.

    Purpose of the Study:

    • To assess the incidence of elbow symptoms and radiographic changes in 11- and 12-year-old baseball pitchers.
    • To investigate potential correlations between pitching experience and elbow abnormalities.

    Main Methods:

    • Clinical and radiographic examination of 120 pitchers aged 11-12.
    • Data collection on pitching experience, elbow symptoms, flexion contractures, and x-ray findings.

    Main Results:

    • 20% of pitchers reported elbow symptoms, 10% had flexion contractures, and 23% showed radiographic changes related to medial traction stress.

  • 5% exhibited lateral compression findings, but without associated symptoms.
  • No statistically significant correlations were found between pitching experience and observed elbow abnormalities.

    • Conclusions:

    • Elbow abnormalities are present in a notable percentage of young pitchers.
    • Current pitching experience does not appear to correlate with these abnormalities in 11- to 12-year-old athletes.
    • Further research is needed to understand the long-term implications and contributing factors to elbow stress injuries in youth baseball.
