Improved bone knife spinous lamina osteotomy replantation complex treatment of lumbar spinal stenosis / 临床外科杂志

ABSTRACT

Objective To improve bone knife spinous lamina osteotomy replantation complex treatment of lumbar spinal stenosis patients.Methods Retrospective analysis from January 2014 to January 2015,the clinical data of 56 patients with lumbar spinal stenosis disease,all patients were taken modified osteotome bone cutting composite lamina spinous process and implant treatment,through follow-up,the CT,preoperatie and follow-up sessions at the end of the measurement of vertebral canal sagittal diameter,spinal canal diameter,to observe the prognosis and complications,and according to the Japanese orthopaedic society of low back pain score standard(Japanese orthopaedics asso ciation,JOA),the rate of good evaluation of clinical curative effect.Results This group of 56 patients with lumbar spinal stenosis disease,the last follow-up,vertebral canal sagittal diameter,spinal canal diameter,than preoperative significantly increased;JOA score was obviously improve the preoperative;The t test,statistically significant difference(P<0.05);The rate of good clinical curative effect was 96.43%;Follow-up period,all patients by CT review that lamina in situ fusion rate was 100%,no lumbar spinal instability,secondary lumbar spinal stenosis,composite lamina spinous complications such as shift,subsidence,fall off;6 months basic achieve bony healing.Conclusion The modified bone knife spinous lamina osteotomy replantation complex therapeutic effect of lumbar spinal stenosis precise,effective reconstruction of posterior structure stability,integrity,reduce complications,the prognosis is good,worthy of clinical use.
