Lumbar spinal stenosis: Evaluation of surgical Results in 100 cases

ABSTRACT

Although lumbur spinal stenosis syndrome is extremely common, considerable controversy continues to surround its classification, diagnosis and treatment. The aim of this study is evaluation of results of surgical therapy for lumbar spinal stenosis in 100 patients. In this article, we retrospectively analyzed the clinical, radiologicaLand surgical results of 100 patients operated in our neurosurgical clinics with the diagnosis of lumbar spinal stenosis. Surgical therapy and outcome are discussed with respect to the known facts. After clinical and radiological evaluation, 100 patients were diagnosed with lumbar spinal stenosis. All patients underwent laminectomy and bilateral foraminotomy at the stenotic level. Surgical outcomes were evaluated as very good, good,same, and poor according to the clinical findings. Fifty- three of the patients were males and forty-seven were females.More than half were between the ages of 40 and 60.The most frequently operated level was L4-L5. Ninety two percent of the surgically treated patients demonstrated very good and good outcomes. Our conclusion in lumbar spinal stenosis diagnosed by objective clinical and radiological findings is that decompressive laminectomy and extensive foraminotomy without instrumentation allow a good outcome:
