Hip Joint Dislocation Reduction T2 Emergency Medicine Procedures, 2e YR 2013 FD 2013 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-161352-1 LK accessemergencymedicine.mhmedical.com/content.aspx?aid=57709174 RD 2024/04/16 AB Hip dislocations are true orthopedic emergencies. The Emergency Physician (EP) must be capable of reducing a dislocated hip. Neurovascular damage to the hip and leg is a consequence of a hip dislocation. Avascular necrosis (AVN) may occur in up to 20% of patients with a hip dislocation. Other studies show that AVN following a hip dislocation is a time-dependent phenomenon. The longer a hip is dislocated, the higher the incidence of avascular necrosis. Dislocation of a hip for more than 6 hours almost universally results in this devastating complication.
