Abstract:
[Objective] To explore the methods,and effect of transforaminal lumbar interbody fusion for lumbar vertebral degenerative instability and degenerative disc disease with herniated nucleus pulposus by microendoscopic surgery. [Methods] 21 cases who underwent transforaminal lumbar interbody fusion by microendoscopic surgery were analyzed retrospectively. [Results] 21 cases were reviewed after surgery. The postoperative follow-up ranged from 12 months to 24 months. No cases converted to open operation. Operative time averaged 150 minutes. Estimated blood loss averaged 120 mL. Mean length of hospital stay was 8 days. There were no nerve injury occurred during operation.In complications,one case suffered from intervertebral infection. Outcomes were quantified using Oswestry Disability Index. The average Oswestry score decreased from 48.3% preoperatively to 16.5% at 3 month and 14 at 6 month postoperatively. The rate of excellent and good was 97.0%. At last follow-up, all patients had solid fusions by radiographic criteria. [Conclusions] Transforaminal lumbar interbody fusion for lumbar vertebral degenerative instability by microendoscopic surgery has the advantages of shorter skin incision, less tissue damage, less blood loss and quicker postoperative recovery.Keywords:
