From July 1994 to June 1997, we collected eight cases with fracture-dislocation of thoracic or lumbar spine. The cases included four accidental falls from a height and four motorcycle accidents. The injury levels were three T11-12, two T12-L1, two L1-2, and one L2-3. Their pre-operative neurological status was four Frankel A, one Frankel B, two Frankel C and one Frankel E. All eight patients were treated by posterior reduction and internal fixation with VSP (Acromed, Cleveland, U.S.). Meanwhile, posterior or posterolateral fusion was performed with autogenous bone grafts. After 2 year’s follow-up, those four patients with complete neurological deficit pre-operatively remained Frankel A after operations. The other three patients who had incomplete neurological deficit pre-operatively, recovered at least one Frankel grade. One of them even restored completely and returned to his work. The only one who was Frankel E pre-operatively, had no neurological deterioration after operation. In addition, his back pain improved. The degree of neurological impairment after fracture-dislocation of spine depends on the severity of canal compromise and nerve root compression. Despite that reduction can not ensure the recovery of neurological deficit. For long term case, surgical treatment to regain the stability of spine is a rational option. |
