Seizures and shock are highly associated with posterior instability, because the internal rotators overpower the external rotators with this stimulus, resulting in a posterior shoulder dislocation. Posterior shoulder dislocations are associated with lesser tuberosity fractures, not greater tuberosity fractures. Posterior instability is much less common than is anterior instability and has a lower risk for recurrent instability. Initial management includes immobilization with a gunslinger-type brace, not with a traditional sling and swath.
- It should be suspected in patients with a history of seizure or shock.
