Application of three-dimensional CT in acetabulum fractures and the Letournel-jutet classification system

Objective To discuss the method of CT three-dimensional reconstruction in acetabulum fractures and the Letournel-judet classification system.Methods Twenty-nine patients with acetabulum fractures were investigated by X-ray and CT three-dimensional reconstruction.According to Letournel-judet classification system of fractures position and direction, 18 cases of simple fractures,including of posterior parietal fractures in 8 cases,posterior column fractures in 3 cases,anterior parietal column fractures in 4 cases, transverse fractures in 3 cases was diagnosed.The diagnosis with complicated fractures was 11 patients,including of posterior parietal and column fractures in 4 cases,anterior parieter and column fractures in 2 cases, T fractures in 3 cases,double column fractures in 2 cases.Results According to CT three-dimensional reconstruction, 16 cases underwent expectant treatment,23 cases underwent operative treatment,with a results of anatomical or proximate to anatomical restitution in all of 23 patients.In the followed-up,there were 8 excellent ,15 good ,the good-excellent rate was 79.3%.Conclusion CT three-dimensional reconstruction have important effects for Letournel-judet classification treatment and operative approaches on acetabulum fracture.
