ABSTRACT
Objective:To investigate effect of single open-door laminoplasty with mini titanium plate implantation for neurological function of patient with cervical spondylosis, and analyze the correlation-ship between the parameters of clinical effects and parameters of vertical plane of cervical vertebra.Methods: 90 patients with ossification of posterior longitudinal ligament (OPLL) of cervical vertebra or multi-segment cervical spondylosis were enrolled in the research. All of them were implemented the treatment of single open-door laminoplasty with mini titanium plate implantation, and they were followed up for more than 6 months. The iconography parameters and clinical effect parameters of patients among pre-operation, post-operation and last follow up were compared and analyzed.Results: The C2~C7 axial distance of vertical plane, visual test analogue scores of neck and JOA scores of 90 patients at the last follow-up were significant higher than that of preoperative results(t=-2.371,t=3.914,t=22.345,P<0.05), respectively, and the dysfunction index of cervical vertebra of the last follow up were significant lesser than that of pre-operation (t=6.323,P<0.05). There were no correlations-ship between the clinical effect parameters and vertical plane parameters of cervical vertebra of 90 patients.Conclusion: The single open-door laminoplasty with mini titanium plate implantation can significantly improve the neurological function of patients with cervical spondylosis, and there is no significant correlation-ship between clinical effect parameter and sagittal view parameter.
