The Added Value of Intraoperative CT Scanner and Screw Navigation in Operative Treatment of Displaced Acetabular Fracture With Dome Impaction

The acetabulum fracture result from a trauma with high energy at the young adult or from a trauma of low energy at the old osteoporotic patient. Anatomic reduction is known to be necessary to give functional result to patient.However, it's technically difficult because of the pelvic bone conformation. The presence of dome impaction makes the surgery more difficult. Per operatory scanner associated to 3D navigation is proved his value-added in spinal surgery.The aim of the study is show that this association permit a technical improvement for the surgeon in the precision of fracture reduction.and restore the articular congruence.
