Paraplegia in flexion was described as long ago as 1837, when Ollivier1 reported Pott's disease with thighs flexed on the pelvis, the legs on the thighs. In 1874, Edes2 reported this disorder in a patient with a tumor of the cord just below the cervical enlargement. This account has been omitted in other reviews of the literature.
In 1883, Demange3 reported the disorder in a man, aged 65, who had painful flexion of both legs. Autopsy disclosed two symmetrical regions of softening in the posterior part of three segments of both lenticular nuclei, that on the right extending further into the external capsule and the small mass of gray matter below the anterior extremity of the optic thalamus beneath the middle commissure. No mention is made of disease in the cord.
In 1899 Babinski4 reported his observations on three patients and the results of postmortem examinations.
