Shoulder Instability



Traumatic Anterior Instability 

History; typically, the humerus is elevated beyond 90 degrees and external rotated. The force is applied at a distance, such as when forearm is trying to block a shot in basketball; the arm is forcefully externally rotated. If the humerus dislocates, a reduction maneuver is often required.

Physical Examination shows; normal appearance in the chronic state, absence of rotator cuff weakness, apprehension with the arm in 90 degrees of abduction and 90 degrees of external rotation.

Nonoperative Treatment includes:

  • Sling for comfort
  • Strengthening
  • Avoid abducted, externally rotated arm position

Operative Treatment includes:

  •      Examination under anesthesia
  • Labral repair to the glenoid fossa
  • Capsulorrhaphy
  • Glenoid fracture repair
