Analysis of Pelvic Fracture Healing Status in 198 Cases.

Abstract

Objective To analyze the relationship between the number of pelvic ring fractures, the location of fracture and Tile type of pelvic fracture and pelvic fracture healing status. To discuss how to understand the pelvic malunion, severe pelvic malunion and bony pelvis deformity （destruction） in Classification of the Impairment Related to Injury. Methods One hundred and ninety-eight cases of evaluation of body impairment class of pelvic fracture caused by traffic accident accepted by Zhongcheng Institute of Forensic Science in 2016 were collected. The cases were statistically analyzed in terms of the distribution of the number of pelvic ring fracture, the location of pelvic ring fracture and Tile type of pelvic fracture in various healing statuses. Results There were 16 cases without pelvic ring fracture, 18 cases of single pelvic ring fracture, 91 cases of 2 pelvic ring fractures, 73 cases of 3 or more pelvic ring fractures, 136 cases of anterior or posterior pelvic ring fractures, 46 cases of simultaneous anterior and posterior ring fractures. There were 34 cases of Tile A type, 130 cases of Tile B type and 24 cases of Tile C type. Statistical analysis results showed that, the differences in distribution of the number of pelvic ring fracture, the location of pelvic ring fracture and Tile type of pelvic ring fracture in various healing statuses had statistical significance （P<0.05）. Conclusion In determination of the healing status of pelvic fracture, preliminary judgment can be made by using the number of pelvic ring fracture, status of pelvic ring fracture and Tile type of pelvic fracture. Caution is required when dealing with single pelvic fractures （including dislocations）, and determining the destruction of bony pelvis.
