Abstract：【Objective】To explore the interim efficacy of different surgical procedures in the treatment of ossification of posterior longitudinal ligament of cervical spine. 【Methods】Ninety-three cases of ossification of posterior longitudinal ligament of cervical spine treated in our hospital from January 2013 to January 2016 were selected. Twenty-seven patients underwent anterior cervical vertebral subtotal resection combined with bone grafting internal fixation as group A. 34 patients underwent posterior single open-door vertebral canal enlargement laminoplasty as group B, and 32 patients underwent total internal fixation with vertebral decompression and lateral mass screw fixation as group C. The Japanese Orthopedic Association (JOA) 17-point method was used to evaluate patients' neurological function and JOA scores before and 1 month after operation. (ROM) percentages and visual analogue scale (VAS) were compared between the three groups after one month. 【Results】The neurologic improvement was found : Excellent in 4 patients (14.8%), Good in 7 patients (25.9%), Fair in 12 patients (44.4%) and Poor in 4 patients (14.8%); 6 patients(17.6%) were found Excellent in the group B, 12 cases (35.2%) Good, 11 cases (32.4%) Fair and 5 cases (14.7%) Poor. The Group C found Excellent in 7 cases (21.9%), Good in 10 cases (31.3%), Fair in 11 cases(34.4% and Poor in 4 cases (12.5%). Neurological improvement rate of three groups of patients was equivalent ; the level of the group A was lower , the difference was statistically significant (P<0.05). Comparison of the incidence of axial symptoms, ROM percentage and VAS score of the three groups of patients found that the group C had lower incidence of axial symptoms, higher ROM percentile and lower VAS score, the difference was statistically significant (P<0.05).【Conclusion】Posterior cervical spine surgery is recommended for patients with ossification of the posterior longitudinal ligament of the cervical spine. The internal fixation of vertebral lamina decompression and lateral mass screw fixation can improve the rate of neurological improvement and decrease the degree of pain.
