Recurrent Atraumatic Anterior Instability


- See: anterior instability

- Discussion:
    - characterized by dislocation occuring after minor trauma, relative ease of relocation, and evidence of multidirectional instability;
    - this condition is often present in overhead throwing athletes;
    - it may lead to thoracic outlet syndrome (dead arm syndrome);
    - causes: 
             - fracture of both the glenoid rim and the greater tuberosity 
             - fracture of the glenoid rim
             - concomitant rotator cuff tear
             - patients w/ a neurological deficit 
             - abnormal glenoid version
             - abnormal humeral version
             - Hill-Sachs lesion 

- Physical Exam:
    - sulcus sign is often seen in pts with multidirectional instability;
          - look for prominent depression below acromion when inferior traction is applied to wrist; 
          - integrity of the rotator interval capsule can be confirmed by a lessening of the sign on external rotation of the shoulder

- Surgical Treatment:
    - arthroscopic reconstruction 

    - remplissage
