Three dimensional computed tomography in diagnosis and treatment of acetabular fracture

Objective To discuss the significance of three dimensional computed tomography in the improvement of clinical diagnosis and therapy of acetabular fracture. Methods 3D CT was performed for 57 cases of displaced acetabular fracture before operation in order to understand the fracture type, design the operation scheme and select proper operative approaches. Results The 57 cases were followed up for 12 to 81 months. Curative effects were assessed according to Maffas evaluation system. By clinic criteria, 43 cases were excellent, 6 cases good, and 8 cases acceptable. By X ray criteria, 44 cases were excellent, 6 cases good, and 7 cases acceptable. Conclusion As 3D CT clearly reveals the stereoscopic injured surfaces, it is helpful in determining position and type of the fracture and severity of the injury so that it can facilitate selection of surgical approach, reduction and appropriate internal fixation during operation.
