[Applicational study of 3D reconstruction with spiral computed tomography in evaluation of anatomical complicated bones fracture].

OBJECTIVE: To investigate forensic diagnosis application of three-dimentional reconstruction with spiral computed tomography in fracture of anatomical complicated bones.

METHODS: Selected eleven patients of bone fracture who were examined with SCT 3D and conventional X-ray examination. The location, number and characteristics were observed and analyzed.

RESULTS: In all of eleven patients with bone fractures, X-ray examination could detect thirty-four rib fracture, one scapula fracture, two nasal fracture, one metacarpal bone incomplete fracture and one left tibia-fibula fracture, one pubis fracture. While there were forty-seven rib fracture, one scapula smash fracture, one nasal fracture with obvious displacement and eliminate one misplace, one left tibia-fibula obsolete fracture and one sacroiliac joint dislocation, one No 5 lumbar vertebrae pedicle of vertebrae arch fracture. Combining 3D reconstruction images, coronary and sagittal reconstruction images could show clearly the fracture line, location of fracture, number of fracture, displacement and recovery.

CONCLUSION: 3D reconstruction technique of SCT is a very useful examination method in the objective forensic diagnosis of anatomical complicated bones fracture, it excels the routine X-ray examination.
