// is defined as spinal stenosis that spinal canal, neural canal and foramina lose their normal width by bone, soft tissue orboth; and surgical indicaton exists only, if neurologic deficit and Us progression present. İn vertebral degenerative cases, decompressive surgery does not prevent degenerative development and its aim is only to re-lease. By continuation of steno2an factor, in the long period spinal canal or lateral stenosis repeatation is possi-ble. İn SSK İstanbul Hospital 2nd Orthopaedic and Taumatology Departmen between May 5, 1992, and August 3, 1993 in ten cases (9 female ■ 1 mafe), for treatment of their spinal stenosis's neurologic symptoms, posterior-posterolateral decomprossion + posterior instrumentation + posterior and posterolateral fusion have been per-formed. Preoperatively, ali cases had had neurologic deficit and spinal stenosis was established by CT or/and MRI. Average patient age is 56.3 years (youngest 35. oldest 63). İn ali cases etiology is degenerative stenosis. Spondylolisthetic patients were excluded from this study. Seven cases which can be followed had been evaluated in May 1994. Average follow-up time is 13 months (betvveen 9 and 24 months). Evalualion have been made according to Osıvestry Katz, Frankel criterias and Deniş painwork scale. By the end of follow-up, in three cases, ali neurologic symptoms had been improved. İn three cases had been improved according to preoperative symptoms but they have rately nerve root irritation findings one case have been stating no difterence in her complaints. Some authors think that posterior decompression (laminectomy or laminatcm) is enough is spinal stenosis, but »ve consider that it is necessary to add posterior instrumentation and posterior fusion to this procedure for prevent posterior instability which may be developed in the end of this method.
