- Anterior labral periosteal sleeve avulsion (ALPSA)
- Coracohumeral ligament (CHL)
- Humeral avulsion of inferior glenohumeral ligament (HAGL)
- By convention, term refers to anterior band of inferior glenohumeral ligament
- Inferior glenohumeral ligament (IGHL)
- Middle glenohumeral ligament (MGHL)
- Reverse HAGL (RHAGL), avulsion of posterior band of inferior glenohumeral ligament
- Superior glenohumeral ligament (SGHL)
- Glenolabral articular disruption (GLAD)
- Superior labrum tear from anterior to posterior (SLAP)
- By definition involves biceps anchor
- May propagate to involve anterior &/or posterior labrum
Definitions
- Injury to anterior labrum & anterior glenohumeral ligaments
- Multiple different patterns of injury distinguished
