The diagnosis of lumbar stenosis. Analysis of clinical and radiographic findings in 43 cases.
This study is based on 43 cases of lumbar spinal stenosis-37 involving the spinal canal and 6 involving isolated radicular canals. The clinical features are analysed, also the radiographic investigations currently used in the investigation of this pathological condition. Three distinct clinical syndromes are differentiated; continuous (acute or chronic), intermittent, combined. The last is the most frequent type. All the patients with stenosis of the canal showed significant radiographic changes, the most frequent being total or subtotal block on myelography with posterior impingement on the dural sac. In stenosis of the radicular canal the affected root was either displaced medially or cut off (amputated). Computerised tomography gives less precise results than radiculography.
