OBJECTIVETo analyze clinical characteristics and therapeutic efficacy of acute traumatic central cervical spinal-cord syndrome without fracture and dislocation,and to investigate its treatment methods.

METHODSClinical data of 47 cases with acute traumatic central cervical spinal-cord syndrome without fracture and dislocation were retrospectively analyzed. There were 3 female and 44 male,with a mean age of 56.2 years (ranging from 46 to 73 years). According to Frankel classification, 30 cases were grade B, 14 cases were grade C and 3 cases were grade D. Forty-two cases were treated without operation, and 5 cases which had significant compression factors or segmental instability were treated with surgical treatment. Among them, 3 cases were treated through anterior approach and 2 cases were treated through posterior approach. Causes of injuries, mechanisms of injuries,findings of imaging, functional impairment of nerve,methods of treatment,and therapeutic efficacy were analyzed.

RESULTSThe average followed-up time was 12 months (ranging form 3 to 84 months), 2 cases of non-operation were dead and 6 were loss. Three months after treatment, some complications occurrenced on 7 patients of non-operation. The majority bequeathed different degree impairment of intrinsic muscles of hands.

CONCLUSIONReduction and fixation through the pedicle of fractured vertebra is an effective therapeutic options to treat the thoracolumbar burst fractures and desearved clinical study and expansion.
