Abstract
OBJECTIVE: Transforaminal endoscopic treatment has been reported to be an effective treatment option in patients with lumbar disc herniation. However, it is rarely performed for spinal stenosis because of the limitation of endoscopic working mobility due to the exiting nerve root and foraminous bony structure. The objective of the present study was to describe a novel transforaminal endoscopic decompression technique for spinal stenosis and report the clinical results.
METHODS: From October 2015 to October 2016, 30 consecutive cases were diagnosed as lateral recess stenosis in our institution and underwent transforaminal endoscopic decompression. The visual analog scales(VAS) of back and leg pain and the Oswestry disability index were measured preoperatively and at the follow-up RESULTS: The mean±standard deviation value of the preoperative VAS score for leg pain was 7.6±1.17. The score improved to 2.2±1.11 at 1 week postoperatively, 1.73±0.96 at 4 weeks postoperatively, and 1.63±0.95 at 26 weeks postoperatively (P<0.01). The mean±standard deviation value of the preoperative ODI was 65.69±14.22. The score improved to 24.29±11.89 at 1 week postoperatively, 21.25±9.25 at 4 weeks postoperatively, and 15.62±10.49 at 26 weeks postoperatively (P<0.01). There were no patients with postoperative infection, dural tear, delayed neurological deterioration, or conversion to open surgery.
CONCLUSION: Transforaminal endoscopic decompression under the local anesthesia could be an effective treatment method for the selected group of patients with spinal stenosis.
