Bilateral posterior shoulder dislocation: the importance of the axillary radiographic view.

Whilst posterior shoulder dislocation is rare, it remains a frequently missed diagnosis. In all patients with a history of seizure, electrocution or similar trauma, where external rotation of the shoulder is limited, we recommend that an axillary or modified axillary view be added to the standard two radiographic shoulder views as routine protocol, to avoid missing a posterior dislocation.
