<< Managing Dislocations of the Hip, Knee, and Ankle in the Emergency Department (Trauma CME)

Summary

Ninety percent of hip dislocations are posterior and present with internal rotation and adduction, while 10% are anterior and present with external rotation and abduction. The initial physical examination and AP pelvic radiograph is usually sufficient to make the diagnosis; however, additional views, such as Judet views, may be needed to evaluate for associated fractures. Traumatic dislocations of the native hip should be reduced within 6 hours to reduce the risk of long-term complications such as avascular necrosis and posttraumatic arthritis. Due to the high incidence of associated injuries, a thorough trauma evaluation is necessary.
