Increased Awareness of the Variability of Glenoid Labral Tear Patterns

Xavier A Duralde*

The glenohumeral joint is a minimally constrained joint with a tremendous range of motion. Stability is gained primarily through a group of ligaments within the glenohumeral joint capsule which connect the proximal humerus to the glenoid through the labrum. Damage to this system of ligaments in the glenohumeral joint can lead to instability either through stretching of the ligaments or tearing of their insertions to the glenoid by detachment of the labrum. Instability of the glenohumeral joint varies both in degree and direction depending on the location and severity of the lesion causing it. Instability often presents with distinct patterns of functional and positional limitations and may include a sensation of impending dislocation, loss of strength and control or pain. For many years, anterior stability was thought to encompass 90% of the identified cases with only 10% of patients identified as presenting with some form of posterior instability.
