[Lumbar canal stenosis: apropos of 64 cases collected at the neurosurgical clinic of the CHU of Dakar]. / Le canal lombaire étroit: à propos de 64 cas colligés à la clinique neurochirurgicale du CHU de Dakar.

ABSTRACT

From 1980 to 1990, 64 cases of Lumbar canal Stenosis have been recorded and operated on at the neurosurgical clinic. The male sex is prevailing and the breakdown by age groups showed a preponderance of the age sections between 31 and 45 and 46 and 60 years. The sciatic pain was the most frequent starting symptom. As far as the physical signs are concerned, the areflexy of the tendon predominates. The saccoradiculography has established the diagnosis in most of the cases. The laminectomy associated with another technique has permitted to obtain the best result of the treatment. With the advent of the T scan, a better estimation of the lumbar canal will be possible, so as to replace the laminectomy by a more adaptable technique the remeasurement of the lumbar canal.
