CLINICAL ANALYSES OF CERVICAL FRACTURE-DISLOCATION WITHOUT SPINAL CORD INJURY

Objective To investigate the etiology, pathological mechanism and treatment of cervical fracture dislocation without spinal cord injury. Methods Nine patients with cervical fracture dislocation without spinal cord injury were male and aged 22 to 63 years. Based on the clinical symptoms and roentgenographic changes, the injury mechanism was analyzed; and the pathological characteristics and treatment principle were put forward. Results Anterior reduction was employed in all 9 cases. Eight cases were reduced completely while 1 case was reduced partially. After following up 1 to 3 years, 7 cases recovered completely and the other 2 cases relieved their symptoms obviously. No nervous symptoms aggravated during the following up period. Conclusion Fracture dislocation of the cervical spine without spinal cord injury has special pathological mechanism. The surgical intervention is needed for solid fixation and complete decompression without any delayed neurosymptoms.
