| Background:In the1950s,Smith-Robinson and Cloward reported the application of anterior cervical discectomy and fusion method for the treatment of cervical disease surgery, afterwards, a variety of posterior interbody fusion appeared in clinic, but how to choose the most effective way of posterior interbody fusion has become the focus of doctors. In recent years, the anterior cervical decompression and interbody fusion has become a widely accepted surgical approach in the treatment of cervical disease. Therefore, the patients with MC+interbody fusion cage in our hospital in recent years were collected and the specific circumstances of the patient, the operation section and the various preoperative and postoperative reference indicators was compared,so as to analyze the efficacy of MC+interbody fusion cage in the treatment of cervical spondylosis.Objective:To explore and analyze the efficacy of MC+interbody fusion cage in the treatment of cervical spondylosis and provide some references for better option in clinic.Methods:From January2011to December2012,54cases patients who accepted cervical spine surgery in our hospital were collected,all patients underwent allogeneic bone anterior cervical decompression and fusion surgery. The patient’s basic information, segmental lesions of cervical intervertebral height and curvature, preoperative and postoperative imaging data, operative time and blood loss, bone healing and fixation-related complications were reviewed and statistically analyzed.Results:52(86segments) of the54patients obtained followed up, due to traffic, cost and other issues, the two exceptions would not get a complete follow-up, the follow-up time was12months. The mean operative time was127.97±21.17minutes and the mean intraoperative blood loss was57.81±26.88ml. The cervical curvature of all patients before preoperative measurements was4.02±0.14mm,the same day after being given cervical lateral, X-ray inspection of the cervical curvature was9.01±0.89mm, at the end of the follow-up, the cervical curvature was8.99±0.1mm. Significant change of the cervical curvature were detected in the preoperative and postoperative and final follow-up, the difference was statistically significant (P<0.05),but no difference was detected between postoperative and final follow-up (P>0.05). Measurements obtained in all cases before surgery intervertebral space was5.06±0.11millimeters,the postoperative measurement was9.02±0.11mm, and the disc space height in the last follow-up was8.99±0.13mm, obvious changes of disc height were found in the preoperative measurement, postoperative measurement and follow-up visit, they could be considered as statistically significant (P<0.05),but no statistical significance was found between the postoperative and final follow-up visit (P>0.05).The preoperative JOA score of the patients was7.13±0.41, last follow-up JOA score was14.39±0.55, which was significantly increased compared with that before treatment, there was significant difference (P<0.05). Single segment, three-segment between two segments except segment increases operative time and slightly prolonged, the cervical curvature, disc height and JOA scores were not statistically significant. Six months after all patients underwent surgery, all segment were essentially100%bony fusion, no fusion cage loose, subsidence and other complications was found.Conclusions:As to the surgical treatment of cervical disease, the use of MC+interbody fusion anterior cervical decompression and fusion surgery can relieve the clinical symptoms significantly compared with that before operation, the intervertebral height and cervical physiological curvature were effectively restored and maintained, and the treatments can obtain satisfactory segmental fusion effect, which significantly improved the neurological function. |
