Role of Multidetector Computed Tomography with Three Dimension Reconstruction in Evaluation of Pelvic Fractures.

Abstract
Background: Pelvic fracture is a serious injury that may be associated with high morbidity and mortality. MDCT is more frequently used for accurate evaluation of pelvic fractures.
Aim of Study: The aim of this work is to evaluate the role of multidetector CT with three dimension reconstruction in diagnosis of pelvic fractures.
Patients and Methods: This prospective study included 70 patients who presented with pelvic fractures and referred from outpatient clinics of Orthopedic Department to the Radiology and Medical Imaging Department, Tanta University Hospital. The present study was performed in the period between February 2018 and March 2019. Their ages ranged from 4 to 82 years; 45 of them were males and 25 were females. All cases underwent multidetector computed tomog-raphy as a rapid, noninvasive diagnostic tool, and the findings were compared with those of plain X-ray.
Results: According to our results patients with partial stable pelvic ring fractures (Tile type B) had higher incidence than stable fractures (54.28%), followed by stable Tile A fractures (28.57%). Young Burgess lateral compression frac-tures had significantly higher incidence (68.57%) especially Young Burgess subtype LC1 (54.28%). All sacral fractures were associated with pelvic ring fratures, Denis zone I was the most common (54.28%). The elementary Judet-Letournel acetabular fractures were the most common (58.82%) espe-cially type posterior wall (20.58%). Hip dislocations and femur head fractures were rare, represented only by 4 cases for each. The most common hip dislocation type was the posterior dislocation represented only by 2 cases (50%).
Conclusion: MDCT with 3D has numerous advantages and accurate in diagnosis of pelvic fratures.
