Summary

Throwing athletes often experience confusing shoulder pain due to the balance between mobility and stability being stressed. Differentiating shoulder instability from impingement is critical for effective treatment.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanics

Background:

  • The glenohumeral joint requires a balance between mobility and stability.
  • Throwing athletes stress this balance through repetitive microtrauma, leading to shoulder pain.

Purpose of the Study:

  • To provide a comprehensive approach to evaluating anterior shoulder pain in throwing athletes.
  • To discuss the anatomy and biomechanics of the shoulder in this population.
  • To outline treatment options, emphasizing nonoperative interventions.

Main Methods:

  • Review of shoulder anatomy and biomechanics relevant to throwing athletes.
  • Discussion of a systematic approach to history and physical examination.
  • Analysis of diagnostic criteria for differentiating instability and impingement.

Main Results:

  • Understanding anatomy and biomechanics is crucial for accurate diagnosis.
  • Differentiating between shoulder instability and impingement is key for treatment selection.
  • A comprehensive evaluation aids in identifying the source of anterior shoulder pain.

Conclusions:

  • Accurate diagnosis of shoulder pain in throwing athletes requires a deep understanding of anatomy and biomechanics.
  • Distinguishing between instability and impingement is paramount for guiding treatment.
  • Nonoperative interventions are a significant component of managing anterior shoulder pain in throwing athletes.
