title: Intermittent claudication of the spinal cord due to ossification of the ligamentum flavum. A report of two cases.
abstract: 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.
