anterior glenolabral injuries

Anterior glenolabral injuries are common in the setting of anterior shoulder dislocation and comprise a number of closely related entities:

• Bankart lesion
• bony Bankart lesion
• anterior labroligamentous periosteal sleeve avulsion (ALPSA)
• Perthes lesion
• glenolabral articular disruption (GLAD)
• humeral avulsion of the glenohumeral ligament (HAGL)
• bony humeral avulsion of the glenohumeral ligament (BHAGL)

These are discussed individually in their respective articles. Below are the key distinguishing features.

• Perthes lesion
  • anterior labrum avulsed, but minimally or undisplaced
  • intact periosteal sleeve lifted off scapular neck
  • inferior glenohumeral ligament complex remains attached to periosteum
• ALPSA
  • similar to Perthes but the inferior glenohumeral ligament complex displaced medially and 'bunched up'
  • labrum displaced inferomedially
• Bankart lesion
  • torn labrum and periosteum
• bony Bankart lesion
  • same as Bankart lesion with associated osteochondral injury of the glenoid rim 
• GLAD
  • only partial tear of the anterior labrum
  • glenoid articular cartilage defect
• HAGL
  • more inferior
  • avulsion of the inferior glenohumeral ligament from its humeral insertion
• BHAGL
  • same as HAGL but with bony avulsion of the medial humerus
