Abstract
We experienced 6 cases of lumbar spinal canal stenosis after compression fracture, for which we performed microendoscopic laminectomy. We examined the usefulness of this approach.
Materials and Methods: We assessed 6 patients who underwent microendoscopic laminectomy between April 2009 and April 2012. The operation was a single-sided approach with bilateral decompression under the METRx system. The parameters examined were the JOA score, Face Rating Score (FRS), the angle and the degree of intervertebral motion before and after the operation, and at the time of the last investigation.
Results: The average JOA score was improved by 8.3 points to 21 points and the average FRS was improved by 5.7 points to 3.0 points. All cases thus showed improvement. The angle of intervertebral motion was 4.8-4.6 degrees, and the degree of intervertebral motion was 0.75-0.98mm. There was no evidence of aggravated instability causing lumbago.
Conclusion: This series revealed neither aggravation of instability nor aggravation of lumbago after surgery.
