Abstract
Objective To compare the efficacy of interbody fusion in the treatment of multi-segment cervi?cal spondylotic myelopathy with different plate fixation. Methods Eighty-four patients with multisegmental cervical spondylotic myelopathy were randomly divided into group A and group B, 42 cases in each group. Both groups were treated with intervertebral fusion with bone graft fusion. While Group A was combined with restric?tive plate, Group B was combined with unrestricted plate. The fusion rates after 12 months, the cervical function and cervical physiological curvature (before operation and 6- and 12-month after operation), the incidence of cervical axis symptoms during follow-up, and the total incidence of postoperative complications were compared between two groups. Results All grafts were fused successfully in two groups. The postoperative JOA scores of both groups were significantly higher (P<0.05). There was no significant difference between the two groups (P>0.05).The curvature of cervical vertebrae increased in both groups (P<0.05), the curvature of cervical ver?tebrae in group A were (14.41 ± 1.31)° and (12.23 ± 1.21)° at 6 months and 12 months, which were respectively higher than those in group B (P<0.05).The incidence of axial symptoms in group A was 4.76%, which was low?er than that in group B(19.05%) (P<0.05). The total incidence of postoperative complications in group A and group B was 4.76% and 7.14%, respectively. Conclusion Intervertebral fusion with bone graft fusion in the treatment of multi-level cervical spondylotic myelopathy can promote graft fusion. Cervical restraint plate can be effective in recuperating physiological curvature and reducing neck axial symptoms.关键词
