| ABSTRACT |
OBJECTIVE
The purpose of this study is to determine the factors that have effects on the neurological deficit in the patients with thoracolumbar fracture.
METHODS
Forty-eight patients were included. Cause of injury, type of injury, time interval, combined injury, kyphotic angle, spinal canal compromise, sagittal diameter, the most narrow sagittal diameter, transverse diameter, the most narrow transverse diameter, and remained height of vertebra body were concerned as the factors. The patients with American Spinal Injury Association(ASIA) impairment scale grade A to D were considered as having neurology while others with ASIA grade E were considered to be without neurology. The patients with ASIA grade A were classified to paraplegia group and the patients with ASIA grade B to E were not thought to be paraplegia. Statistical analysis for these groups were performed.
RESULTS
Spinal canal compromise (P<0.001) have correlation with neurological deficit. The most narrow sagittal diameter was smaller in the group with deficit than that in the group without deficit (P=0.004). Also, combined injury have correlation with neurology (P=0.028). Spinal canal compromise (P<0.001), sagittal diameter (P=0.032), the most narrow sagittal diameter (P=0.025), and Denis type (P<0.001) also have correlation with paraplegia.
CONCLUSION
The factors of percentage of spinal canal compromise, the most narrow sagittal diameter, and combined injury are predictive of neurological deficit. The patients with paraplegia may be predicted by the factors such as type of injury, spinal canal compromise, sagittal diameter, the most narrow sagittal diameter, and Denis type. |
