Abstract:
Objective To evaluate the clinical outcome of lumbar spinal canal stenosis treated by microen-descopic discectomy. Methods The rear guard intervertebral discoscope was used to carry on unilateral or-bilateral "windowing" to relieve the dura mater spinalis and the nerve root oppression thoroughly. The "C" ann machine or laferal side photography position X was used for localization. Approximately 1.5 cm incision was made under local anesthesia or under the shallow epidural anaesthesia at posterior waist, the pathway tube was implanted after progressive expansion, part of lamina of vertebra was removed by drill, endoscope was inserted under the television surveillance to reveal removed lamina of verfebra, the proliferated cohesed articular process, the plump yellow ligament flava and the bulging intervertebral disc nucleus pulposus tis-sues, the nerve root canal was depressed, to relieve thoroughly its oppression, dura mater and nerve root. Results The follow-up continued from 5 months to 36 months. The evaluation with Nakai scale revealed ex-cellent in 168 cases, good in 9 cases, fair in 6 cases. The rate of good results was 96.7%. Conclusions Totally 183 cases were treated with this procedure posterior microendoscropie discectomy shows minimal inva-sion, less blood loss and quick recovery. The stability of lumbar spine can be reserved. It is safe and effec-tive for treating lumbar disc herniation complicated with spinal stenesis.
