title: Absence of limitation of straight leg raising in proved lumbar disc lesion: case report.
abstract: The absence of the classical clinical sign of limitation of strainght leg raising is reported in one patient and summarized in 14 others who had all the other clinical signs of disc protrusion and in whom the disc lesion was proved by myelography and at surgery. It is postulated that the absence of this important sign may be explained by the daily habits of patients who stoop and bend to perform their household duties. Such posture leads to an elongation of the nerve roots, which permits a full range of straight leg raising. It is worth remembering that this sign may be absent in some patients with a disc lesion.
