A 19-year-old male was admitted to a hospital for treatment of traumatic fracture-dislocation of the hip sustained in a traffic accident. Closed reduction was directly carried out after diagnosis. However, he was referred to hospital was introduced for surgery. First, stereographic processing of CT figures in the hip was done to determine the therapeutics. It appeared that, if the hip was flexed, the fracture portion would be led to the weight-bearing region. Next, the computer simulation of rotational osteotomy of the femoral head was carried out. This showed that weight bearing of the fracture portion could be avoided by 60° of anterior rotasion. So, 30 days after injury, osteotomy of the femoral head with 60° of anterior rotation was made after fragments were removed. Thus, the simulation for traumatic fracture-dislocation of the hip was not only a useful method for the three-dimensional understanding of the focus, but also the determination of the therapeutics.
