Abstract：Objective To investigate the characteristics of central cord syndrome without fracture or dislocation and assess the effect of surgical management.Methods Twenty-one cases of central cord syndrome without fracture or dislocation were diagnosed with X-ray radiography,CT and MRI and treated surgically.Spinal cord dysfunction and its recovery rate were evaluated using American Spinal Injury Association (ASIA) system.Radiological and clinical evaluation was performed for all cases.Pre-and postoperative ASIA scale and score were statistically analyzed.Results All cases sustained cervical spinal cord compression resulting from cervical disc herniation in 18 cases,of which five were accompanied by ligamentum flavum hypertrophy and reductus,developmental cervical spinal canal stenosis in two cases and posterior longitudinal ligament ossification in one case.Neurological dysfunction involved in the upper extremity in 15 cases and upper and lower extremity in six cases.Mean period of follow-up was 13.5months.ASIA scale was improved from C (n =9) and D (n =12) before operation to C (n =1),D (n =6) and E (n =14) in the last follow-up.ASIA score of motor and sensory dysfunction revealed a (84.3 ±12.5)％ and (62.7 ± 14.6)％ improvements,with significant difference as compared with the preoperative one (P ＜0.05).Conclusions Cervical disc herniation is the major factor of spinal cord compression in central cord syndrome without fracture and dislocation.Neurological dysfunction occurs mostly in the upper extremity.Surgery is an effective method to release spinal cord compression and restore neurological function.
