[Correlation of disability degree and Tile type of pelvic fracture caused by traffic accidents].

OBJECTIVE
To analyze the relevance of Tile type of pelvic fracture and the degree of disability and explore how to understand the malunion and severe malunion of pelvic fracture for the injured in the traffic accidents.


METHODS
Eighty-six cases of pelvic fractures caused by traffic accidents from August 2008 to August 2011 in Forensic Judical Appraisal Institute of Suzhou Municipal Hospital were collected. At first, the grade of disability for every case was evaluated by 3 senior forensic experts independently. Then, the Tile type of pelvic fractures for every case was determined by 3 radiologists independently. At last, the correlation of the types of the fracture with the grades of disabilities was analyzed.


RESULTS
In all the cases there were 19 cases determined as A-type fracture and evaluated as non-grade disability. There were 43 cases determined as B-type fracture. And in these cases there were 41 cases determined as tenth grade of disability, one case as non-grade disability and one case as ninth grade disability. There were 24 cases determined as C-type fracture. And in these cases there were 14 cases evaluated as tenth grade disability and 10 cases evaluated as ninth grade disability. There was a correlation between the grade of disability and the type of the fracture (r = 0.760).


CONCLUSION
The disability degree caused by pelvic fracture correlates significantly with the type of the fracture. The finding is potentially useful to understand the malunion and severe malunion of pelvic fracture in forensic practice.
