Abstract
Objective:
To review some of the important biomechanical factors that provide glenohumeral stability, along with the pathologic mechanisms involved in glenohumeral instability of the shoulder.
Data Sources:
Current English medical literature concerning the multiple pathologic factors involved in glenohumeral instability was reviewed.
Data Synthesis:
Multiple dynamic and static factors control glenohumeral instability. Knowledge of normal shoulder anatomy and biomechanics is necessary to interpret pathologic events.
Conclusions/Recommendations:
Dynamic and static factors collectively provide stability to the glenohumeral joint. Disruption or malfunction of these factors causes dysfunction in the shoulder.
Keywords: anatomy, biomechanics, glenohumeral
