Issue:
Could the restrained driver of a passenger sedan suffer an anterior-inferior shoulder dislocation in a front-end motor vehicle collision?

Anterior Glenohumeral Dislocation

Results:
Northstar Biokinetics determined that the shoulder dislocation could not have been caused by the vehicle accident. Because this case involved a frontal collision, the driver’s shoulder would have been subjected to posteriorly directed forces that could not have caused the dislocation; the shoulder restraint and active bracing would have limited forward excursion. In addition, the driver was involved in recreational activities that could have created a traumatic shoulder dislocation.
