Clinical application study of modified laminectomy and selective extended decompression plus internal fixation in the treatment of multiple segmental cervical spondylosis
Abstract：ObjectiveTo investigate the clinical effects of application of modified laminectomy,selective decompression and internal fixation in the treatment of patients with multiple segmental cervical spondylosis.MethodsAltogether 84 patients with multiple segmental cervical spondylosis who were treated in our hospital from February 2015 to January 2017 were selected and randomly divided into the control group and the observation group,with 42 cases in each group.The control group was treated with conventional laminectomy decompression and internal fixation,while,the observation group was treated with single-door improved laminectomy and selective decompression combined with internal fixation of the pedicle screw system.The neurological functions,the improvement of cervical functions and the incidence of complications were compared between the two groups.ResultsThe JOA score,NDI score and cervical mobility of the two groups after operation were better than those before operation,the JOA score,NDI score and cervical mobility of the observation group after operation were significantly better than those of the control group,with significant difference (P＜0.05).The incidence of postoperative back pain and C5nerve root paralysis in the observation group was significantly lower than that in the control group,with significant difference(P＜0.05).ConclusionApplication of modified laminectomy,selective decompression combined with internal fixation in the treatment of multiple segmental cervical spondylosis can significantly restore patients′nerve functions and cervical functions,which promotes the improvement of cervical vertebra activity and actively inhibits the complications.
