Case Discussion

Typical appearances of an anterior glenohumeral dislocation. 

Anterior shoulder dislocation is by far the most common type of dislocation of the shoulder, and one of the most common joint dislocations anywhere in the body. It usually results from forced abduction, external rotation and extension.

Anterior dislocations can be further divided according to where the humeral head comes to lie:

  • subcoracoid - most common
  • subglenoid
  • subclavicular
  • intrathoracic - very rare
