Anterior dislocations (in which the humeral head is displaced anteriorly in relation to the glenoid), account for as many as 95-98% of shoulder dislocations. [1] The reason is that the muscular and ligamentous support anterior to the humeral head is much less robust than the substantial muscular and bony support afforded posteriorly by the rotator cuff and scapula. Anterior shoulder dislocations may be divided into the following four types:

  • Subcoracoid
  • Subglenoid
  • Subclavicular
  • Intrathoracic
