title: Spinal trauma in mainland China from 2001 to 2007: an epidemiological study based on a nationwide database.
abstract: METHODS
  Descriptive epidemiological study.
  
  
  OBJECTIVE
  To determine the epidemiological characteristics of spinal trauma in Mainland China.
  
  
  BACKGROUND
  To date, a large-scale epidemiological analysis of spinal trauma in Mainland China has not been undertaken.
  
  
  METHODS
  Data were acquired from Chinese Database of Traumas. Patients with International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) coding of 805.x and 806.x (spinal column fracture with and without spinal cord injury) from 2001 to 2007 were identified. Variables assessed included patient demographics, etiology, segmental distribution, and outcomes.
  
  
  RESULTS
  A total of 82,720 patients with spinal trauma were identified, accounting for 4.58% of all trauma patients in the study period. Spinal cord injuries (SCIs) and fracture-dislocations accounted for 16.87% and 7.17% of spinal trauma and 0.74% and 0.32% of all traumas in the same period, respectively. The male-to-female ratio was 2.33:1. About 79.32% of spinal trauma occurred in patients between 20 and 60 years of age. There was an annual increase in incidence during the study period. A total of 64,630 patients (78.13%) had a definitive cause, with motor vehicle accidents identified as the leading etiological factor (33.61%), followed by high falls (31.25%) and trivial falls (23.23%). Lumbar spine was most frequently involved (56.09%), followed by thoracic spine (23.77%), cervical spine (17.75%), and sacrococcygeal vertebrae (2.39%). Fracture-dislocation occurred most frequently in the cervical and lumbar spines, whereas spinal cord injury occurred most frequently in the cervical and thoracic spines. Children younger than 10 years of age were prone to cervical spine injury, whereas adults older than 60 years were more prone to osteoporotic thoracic and lumbar fractures. Overall rate of conservative treatment (55.88%) was higher than that of operative treatment (44.12%). Overall combined cure and improvement rates exceeded 90%. The male mortality rate was twice that of the female population. Lumbar spine injury was the most curable, whereas cervical spine injury was associated with the worst prognosis and the highest medical costs.
  
  
  CONCLUSIONS
  This is the first large-scale epidemiological study of spinal injury in Mainland China. The results obtained have important implications for future public health care planning, public safety, and resource allocation.
