In his Cyclopedia of the Diseases of Children, Keating records a statement of Scanzoni that he "had never met with luxations in the newly born, yet they occur, sometimes as congenital lesions, sometimes and not very seldom, at the hip as the result of powerful traction on the lower extremities." The dislocation of one vertebra on another is mentioned by medical writers as a possible cause of birth palsy, but a survey of the literature reveals no description nor report of a case. A brief account is recorded here of a case which may undoubtedly be considered a luxation of the first lumbar on the second lumbar vertebra, occurring at birth and causing a subsequent permanent deformity and permanent flaccid paralysis of both lower extremities below the knees.
