Enlarging study of posterior cervical decompression responsibility segment

Abstract

Objective To compare the medium-term efficacy of responsibility posterior segmental spinal decompression vs. expansion with traditional C3-C7 posterior decompression for treatment of multilevel cervical spinal stenosis. Methods A retrospective analysis from January 2013 to January 2015 in our hospital was performed on 137 patients undergoing posterior surgery, and responsibility segmental posterior spinal canal decompression group (A, n=64), and traditional C3-C7 posterior decompression group (B, n=73 cases) were set up. According to the results of follow-up, operative time, blood loss, preoperative and postoperative follow-up Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS) score, and neurological improvement rate were analyzed. Results In responsibility segment posterior spinal canal decompression surgery group, pre-operative JOA score was (7.3±1.8), (9.3±1.8) at third month, and (13.1±1.1) at the end of follow-up; the pre-operative VAS score was (8.1±1.1), (6.1±0.9) at third month, and (3.3±0.9) at the end of follow-up. In traditional C3-C7 posterior decompression surgery group, pre-operative JOA score was (7.1±1.7), (9.2±1.7) at third month, and (13.0±1.4) at the end of follow-up; the preoperative VAS was (8.2±1.0), (6.4±0.8) at third month, and (2.9±0.9) at the end of follow-up. Pre-operative and post-operative JOA score between the two groups showed no significant difference (P>0.05), and at the end of follow-up VAS score was statistically significant (P 0.05), and blood loss was reduced and operative time was shortened in responsibility posterior segmental spinal canal decompression group as compared with those in the traditional C3-C7 posterior decompression group (P<0.05). Conclusion Responsibility segment posterior spinal canal decompression can also achieve good clinical efficacy. Responsibility segmental decompression operation time is shorter and blood loss is less, and can better improve the medium-term patients’ subjective symptoms.
