OBJECTIVE@#To observe the change of cervical curvature and range of motion (ROM) on imaging at 6 months after Hybrid surgery.@*METHODS@#A total of 29 patients with cervical degenerative disease who underwent Hybrid surgery from January 2017 to July 2018 were retrospectively analyzed. Also, they all met the inclusion criteria and had complete preoperative and 6 months postoperative imaging data. There were 11 males and 18 females, aged from 34 to 76 (55.86±10.69) years, and the operation time was from 2 to 4(3.03±0.51) hours. The Cobb angle method was used to measure the changes of cervical curvature and ROM of C@*RESULTS@#There was no statistically significant difference in C@*CONCLUSION@#Hybrid surgery reconstructs the lordotic curvature of the entire cervical spine and the responsible segment, retains the ROM of the cervical replacement segment, and restores the biomechanical function of cervical spine.

OBJECTIVE@#To investigate the clinical effect of anterior cervical Hybrid surgery in the treatment of cervical degenerative diseases (CDD) and observe the incidence of heterotopic ossification of disc replacement segment at 1 year after surgery.@*METHODS@#From January 2015 to April 2018, 35 patients who received anterior cervical hybrid surgery met the inclusion and exclusion criteria and the complete clinical follow up data were analyzed retrospectively. Complete imaging follow-up data were obtained from 24 patients. There were 15 males and 20 females, aged from 39 to 70(55.57±7.73) years old. The amount of bleeding was for 20 to 100 (40.29±18.39) ml, and the hospitalstay was for 4 to 28(11.03±4.63) days, and the follow-up time was(12.97±1.36) months. Clinical outcomes were assessed by the Tanaka Yasushi cervical spondylitis symptom scale 20 score (YT20), and Japanese Orthopaedic Association (JOA) score. The occurrence of heterotopic ossification after Hybrid surgery was evaluated by X-ray according to McAfee standard one year after operation. Patients with or without heterotopic ossificationwere divided into two groups and their clinical effects were compared.@*RESULTS@#At the final follow up, the mean YT20 score and JOA score were significantly higher than those before operation (P <0.05), and the average improvement rate of JOA was (70.66 ±0.44)%. One year after operation, the heterotopic ossification occurred in 10 of 24 segments, with incidence of 41.70%(10/24), including 29.20% in gradeⅠand 12.50% in gradeⅡ. The results of clinical efficacy comparison between patients with and without heterotopic ossification were as follows:there was no significant difference in JOA score before and after operation (@*CONCLUSION@#The short-term clinical effect of Hybrid surgery is satisfactory for cervical degenerative diseases, and the cause of heterotopic ossification still needs tobe further explored.

<p><b>OBJECTIVE</b>To evaluate the intermediate and long-term follow-up effect of posterior dynamic lumbar stabilization in lumbar degenerative disease.</p><p><b>METHODS</b>The clinical outcomes of 96 patients (male 51, female 45, age from 21 to 68 years, mean 41.5 years) whose follow-up time were more than 2 years with lumbar degenerative disease treated by posterior decompression with Wallis posterior dynamic lumbar stabilization implant or combined with posterior lumbar fusion from August 2007 to January 2010 were retrospectively studied, and assessed with visual analogue scale (VAS) and spinal operative standard of Chinese Medical Association. The early and long-term follow-up effect and complications associated with Wallis posterior dynamic lumbar stabilization were recorded. The height of intervertebral space at the treated level in lateral plain film were measured at preoperatively, 3 month postoperatively and last follow-up, respectively. The finds of MRI obtained at over 6 month postoperative were recorded.</p><p><b>RESULTS</b>The operative procedure of Wallis posterior dynamic lumbar stabilization implant was easy and less invasive. The VAS scores were 78 ± 24, 28 ± 16 and 14 ± 12 preoperatively, 3 month postoperatively and last follow-up, respectively. The good or excellent result was 91.7% at the last follow-up. No complication related with Wallis posterior dynamic lumbar stabilization was found. The rate of patient's satisfaction with the Wallis implant operation was 95.8%. The disc height at the treated level in lateral plain film were (8.2 ± 3.7), (10.4 ± 2.6) and (10.1 ± 1.9) mm at preoperatively, 3 month postoperatively and last follow-up, respectively. There is no further degenerative change found in MRI obtained at over 6 month postoperative. MRI 1 year after Wallis procedure showed rehydration of the formerly black disc at the treated level.</p><p><b>CONCLUSIONS</b>It is easy and safe to use Wallis posterior dynamic lumbar stabilization in treatment of degenerative lumbar disease, and the effect of the intermediate and long-term follow-up more than 2 years is good. The Wallis system provides an alternative for treatment of lumbar degenerative disease.</p>
