Forensic Analysis of 8 Cases on Assessing Traffic Accident Disability Grade of Kümmell's Disease

Objective To provide a reference for the assessment of the disability grade of Kümmell's disease cases, through the analysis of the basic situation, the disability grade and the causality of Kümmell's disease cases. Methods Data of appraised individuals in 8 cases of Kümmell's disease from traffic accident spinal injury cases accepted by the Institute from 2015 to 2017 were collected, and the basic situation, vertebral fracture sites and disability grades of the appraised individuals were analyzed. Results Among 8 cases of appraised individuals, there were 2 males and 6 females, the oldest 75 years and the youngest 50 years, with an average age of 62.5 years, all of whom suffered from single vertebral fracture. Among them, 1 patient had thoracic 11 vertebra fracture, 3 thoracic 12 vertebra fracture, 2 lumbar 1 vertebra fracture, 1 lumbar 2 vertebra fracture, and 1 lumbar 4 vertebra fracture, all of whom were assessed as grade 10 disability. Conclusion In the assessment of disability grade of vertebral fracture, dynamic observation of the vertebral fracture and its recovery should be made based on imaging data. If it is suspected that there is Kümmell's disease, it should be differentiated from other diseases. Also, the disability grade will be assessed according to the corresponding standards when the morphology of the injured vertebral body is relatively stable.
