Axillary nerve injury after anterior glenohumeral dislocation: MR findings in three patients.

Abstract

We performed this study to demonstrate the MR imaging findings that indicate an anterior dislocation has caused an axillary nerve injury. MR images of the shoulder can show findings indicating that an axillary nerve injury has been caused by an anterior shoulder dislocation. All MR examinations should be evaluated for these findings, particularly if the patient has a history of anterior shoulder dislocation.
