AbER injury
Direct Trauma
Subluxation vs Dislocation
ER reduction“Popped it in myself”
“Went in and out”
“Load and Shift”
Grade 1- up faceGrade 2- on rimGrade 3- over rim
AbER reproduces symptoms
Posterior force relieves symptoms
Inferior translation
Interval lesion
Resolves in external rotation?
Bankart Lesion
Caps-labral complex off glenoid
Classic lesionTraumatic Dislocators
Bony Bankart Lesion
Bankart lesion with anterior glenoid rim fracture
ALPSA lesion
Healed BankartTension off GH ligaments
Release and repair anatomically
Tear/deficiency of interval capsule
Restraint to inferior translation
Sulcus sign
Humeral Avulsion of Glenohumeral Ligaments
≈10% of patients
Pre-op MRI
Usually open Repair
Recently Arthroscopic
Karas, Spang Arthroscopy 2005
Glenolabral Articular Disruption
Superficial anterior-inferior labral tear
Associated with anterior-inferior articular cartilage injury
Posterior Humeral Head Defect
Increased Dislocation Rate
“Remplissage”
Fills defect with infraspinatus
Plain Film

Capsular anatomy Bankart v HAGL
Glenoid insufficiency (CT better)
Interval lesion SLAP Arthrogram improves

1.4/athlete/seasonBuss, AJSM, 2004
External Rotation Immobilization
F/U 15 mos Recurrence IR- 30% ER- 0 Recent information not a
favorable… Probably does work better
than internal rotation (Hovelius 1996; Kiviluoto, 1980)

Nonoperative Treatment Has a Higher Recurrence
Rate than Arthroscopic Repair
