ABSTRACT
The typical presentation in a posterior dislocation is a shortened, slightly flexed, internally rotated and adducted
limb. This presentation may be altered by injuries to the ipsilateral extremity and acetabulum. Approximately 50% of patients sustain concomitant fractures and major organ or other musculoskeletal injuries, and they should be carefully looked for. Ipsilateral knee, patellar and femur fractures are the commonly associated injuries. Sciatic nerve injury is present in 10-20% of posterior dislocations; therefore, a neurovascular examination of the ipsilateral limb is essential.
