Clinical Study for the Spondylolysis with Adjacent Disc Lesion and Spinal Canal Stenosis

Abstract

Clinical study was performed on 40 cases of surgically treated spondylolysis with adjacent disc lesion and spinal canal stenosis. In these cases, appropriate approach must be selected for each of cases. Operative methods which we performed for adjacent disc lesion group were as follows: (1) anterior interbody fusion for adjacent disc and affected disc, (2) anterior interbody fusion for adjacent disc and bone graft in the lytic portion, (3) anterior interbody fusion for adjacent disc and disectomy for affected disc, (4) laminectomy and posterolateral fusion for multiple lesions, and (5) Love's method for adjacent disc. On the other hand, operative methods for spinal canal stenosis group were as follows: (1) laminectomy only, (2) laminectomy and posterolateral fusion, (3) laminectomy and anterior interbody fusion for affected disc, and (4) fenestration operation for multiple lesions.
They were followed more than one year after surgery. Postoperative improving rate more than 80% by J. O. A. score was noted in 76% of adjacent disc lesion group and 62.5% of spinal canal stenosis group.
