β¦ Synopsis
Two patients are described who developed intermittent claudication of the spinal cord which caused spastic paraparesis during walking. The cause in both was multi-level ossification of the ligamentum flavum. Epidural spinal cord evoked potentials showed disappearance of the third negative component in one case, and positive-going waves in the most compressed area. Both patients had excellent neurological improvement after resection of the ossified ligament. R 6 s u m 6 . Prisentation de deux malades atteints du rare syndrome de claudication intermittente de la moelle. Tousles deux pr6sentaient une ossification du ligament jaune (OLF) au niveau du rachis dorsal, plusieurs dtages, induisant une parapaMsie spastique durant la marche sur une certaine distance. Les sympt6mes disparaissaient peu aprks l'arrOt mais rdapparaissaient d~s la reprise de la marche. Les potentiels dvoquds de la moelle dpinibre dpidurale (PEME) ont montrd la disparition du troisikme composant ndgatif dans un cas et dans l' autre des ondes g~ transition positive dans les sites particulidrement comprimds par I'OLF. Les PEME ont facilit( le diagnostic des ldsions en cause et une excellente amdlioration neurologique a dtd obtenue chez les deux patients apr~s r6section de t'OLF.
