Clinical and Radiological Evaluation of Posterior Decompression for Lumbar Canal Stenosis.

Clinical results of 38 cases of lumbar canal stenosis treated by posterior decompression were studied and 10 cases were further evaluated radiologically.In most cases intermittent claudication, intermittent sense of retention, pollakisuria and perineal dysesthesia disappeared postoperatively. However, motor weakness and subjective sensory disturbances, especially in the S1 innervating area persisted postoperatively in the majority of cases.Ten cases were evaluated by both pre- and postoperative CTM, and stenotic changes in the lateral recess were found preoperatively in 4 cases. Three of these cases recovered from intermittent claudication after surgery, although their post-operative CTM revealed that no decompression had been done on the lateral recess. These results suggest that in some cases intermittent claudication is not caused by stenotic changes of the lateral recess.
