Lumbar spinal stenosis

SummaryLumbar spinal stenosis was studied in 106 cases. Causative factors are defined. Three groups are classified according to symptoms. Two factors responsible for the symptoms of cauda equina claudication are considered to be swelling of nerve roots and vasodilatation and the importance of posture is stressed. Finally, the results of conservative and operative treatment are discussed together with the indications.RésuméLes auteurs ont étudié 106 cas de canal lombaire étroit. Ils en rappellent les causes et classent leurs observations en trois groupes en fonction des symptômes présentés.Le syndrome de claudication intermittente de la queue de cheval peut être imputé à deux causes: l'oedème des racines et la vaso-dilatation péri-neurale. On doit également insister sur l'importance des facteurs posturaux.Enfin, les résultats obtenus après traitement conservateur ou chirurgical sont analysés et les indications propres à chacun d'eux précisées.
