Epiphyseal Injuries in Sports.

The Physician and sportsmedicine·2016

Professional baseball pitchers often exhibit reduced nerve function in their throwing arm, indicating a repetitive use injury affecting the brachial plexus. This finding is crucial for interpreting diagnostic tests in players experiencing arm pain.

Area of Science:

  • Sports Medicine
  • Neurology
  • Orthopedics

Background:

  • Pitcher's arm is a common concern in baseball.
  • Understanding its underlying pathology is essential for player health and performance.

Observation:

  • Reduced sensory nerve action potentials were observed in the throwing arms of most professional and many amateur baseball pitchers studied.
  • Six clinical cases illustrated the range of symptoms associated with pitcher's arm.

Findings:

  • The study suggests pitcher's arm is a pathological condition, likely a repetitive use syndrome impacting the brachial plexus.
  • This condition, while not demonstrably affecting performance, has significant diagnostic implications.

Implications:

  • Electrodiagnostic studies in symptomatic pitchers require careful interpretation due to potential nerve alterations.
  • This research highlights the need for specialized diagnostic approaches for throwing athletes.
  • Further investigation into repetitive use injuries in athletes is warranted.
