AbstractHip joint is naturally a very stable joint and tends to require a significant amount of force to dislocate. Dislocation of hips usually occur in young individuals. Traumatic hip dislocations are common in high-energy automobile accidents. The amount of energy, position of hip at the time of trauma and its morphology determines the type of dislocation, its direction and the associated fractures. These factors are to be taken into consideration while assessing the case of hip dislocation in emergency. Such patients require a standard trauma evaluation, a thorough musculoskeletal and neurological examination and detailed radiographic evaluation. Here we present a case of 40-year-old man who sustained posterior hip dislocation with posterior wall acetabular fracture with lipo-hemarthrosis. Urgent open reduction and internal fixation of the posterior acetabular wall was done with recon plate and screws were done. To our knowledge, such injuries occur less often in the literature with such findings. Possible mechanism of injury and operative procedures are discussed
