[Lumbar canal stenosis in Ouagadougou: aetiological, clinical aspects and prognosis regarding 80 cases]. / Le canal lombaire étroit à Ouagadougou: aspects étiologiques, cliniques et pronostiques sur une étude de 80 cas.

The authors report their experience about 80 cases operated for lumbar spinal stenosis. Etiological clinical aspects and prognosis are studied. Lumbar arthrosis (83.8%) is the most frequent aetiology. The mean age is 50.7 years. Men are most affected than women (sex-ratio 2/1). Heavy work has a part to play in the genesis, in effect it tends to low the age of symptomatic stenosis. Lumbar and radicular pains are the most frequent symptoms (82.5%). Neurogenic intermittent claudication is less frequent (65%). Heavy cases with neurologic complications are frequent (32.5%). Surgical results are satisfactory in 74.3% of the cases. The authors insist in the interest of extensive laminectomy, respecting however as much as possible, the structure of stability of the vertebral column.
