Introduction: Luxatio erecta femoris or inferior hip dislocation is the rarest type of hip dislocation. It can be caused by a severe trauma to the hip and the mechanism of injury is often very complex. Very few cases have been reported in the literature, and often associated with other musculoskeletal injuries. Overall about 3026 cases were reported till recently. Case Presentations:We came across five cases of Luxatio erecta femoris from our six year study period from 2015 to 2020. All five cases were males (mean age-28.4 years, age range 20–40 years). All of them were isolated injuries (pure dislocation without any associated femur, acetabular, or pelvic fractures). We will present the details of these cases along with review of literature, trying to unravel the mechanism of such an injuries. Conclusion:With the increase in high energy road traffic accidents, the incidence of luxatio erecta femoris in adults has increased. We could identify all those injuries and treated it with excellent clinical outcome. This type of rare dislocations if properly identified, we can manage it without much delay and very minimal complications. Keywords:Luxatio erecta femoris, dislocation, trauma.

BACKGROUND Around three lakh accidents occur in India every year injuring upto 3,40,000 people. Injuries to the pedestrian occur as a result of acceleration process. There can be an abrasion, contusion, laceration or fracture. Injuries can be grouped as  Primary Impact Injuries: This is the first contact of vehicle over the victim's body. It can be an abrasion or contusion and may bear the design of the part of vehicle which struck the victim. The part of the body involved depends upon the position of the victim or the dimension of the offending vehicle.  Secondary Impact Injuries: Following the primary impact the victim can be scooped up and the vehicle can impact over other parts of his body producing injuries.  Secondary Injuries: These occur when the victim is knocked down following impact. These injuries are as a result of the victim striking the ground or any other intervening object.  Crush Injuries: these are seen when the victim is run over by the vehicle. The severity depends upon the weight of the vehicle. 2
