Methods Clinical data of 68 consecutive patients who underwent surgical treatment from 2003-08-01 to 2006-12-01 were collected. The quantization of the efficacy of operation was made by applying Japanese Orthopedic Association (JOA) scoring system, based on which the recovery rate and satisfaction rate were calculated. In the patients who underwent anterior approach, we compared the recovery rate among the subgroups of different duration of symptoms, age at surgery and the severity of diseases. Any surgery-related complications were also noted. Results 73.5% (50/68) patients underwent anterior approach, with an average recovery rate of (68.21 ± 10.06)% and the satisfaction rate of 88.00%;20.6% patients (14/68) underwent posterior approach, with an average recovery rate of (64.03 ± 7.07)% and the satisfaction rate of 100%. The recovery rate had no significant difference in the two approaches. Only 4 patients (5.9%) underwent anterior and posterior combined approach, and the recovery rate and the satisfaction rate were 65.10% and 100%, respectively. In the group of patients who accepted anterior approach, no significant differences were found in the recovery rates of different age subgroups and different duration of symptom subgroups;the significant differences recovery rates between the moderate and severe subgroups were identified. Minor complications, such as asymptomatic screw misplacement, transient dysphagia/odynophagia, pain related to the donor site and axial syndrome, were observed in a few patients. Conclusion The JOA score can be improved by applying the appropriate approaches and the high recovery and satisfaction rates can be achieved at the same time. The efficacies of anterior and posterior approaches were similar. The complications of surgery were minor. In the patients who underwent anterior approach, the severity of diseases was a predictive factor for the outcome of surgery.展开更多
