Summary

Superior glenoid impingement can injure five key shoulder structures, including the rotator cuff and labrum. Understanding these injuries is crucial for overhead athletes, though clinical signs are still being defined.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Anatomy

Background:

  • Superior glenoid impingement is a newly identified cause of shoulder injury.
  • This condition affects critical shoulder structures, impacting athletes.
  • The clinical presentation and full impact are not yet widely understood.

Purpose of the Study:

  • To define the structures at risk from superior glenoid impingement.
  • To describe the clinical implications and natural history of this injury pattern.
  • To provide a comprehensive overview for overhead athletes and clinicians.

Main Methods:

  • Literature review of superior glenoid impingement.
  • Analysis of anatomical structures involved.
  • Synthesis of clinical findings and natural history data.

Main Results:

  • Identified five key structures at risk: rotator cuff, superior labrum, greater tuberosity, superior glenoid, and inferior glenohumeral ligament.
  • Clinical presentation varies based on the specific structures injured.
  • Natural history is well-documented for overhead athletes.

Conclusions:

  • Superior glenoid impingement poses a risk to multiple shoulder components.
  • Further research is needed to fully elucidate the clinical picture.
  • Awareness is key for managing this injury in athletic populations.
