چکیده
The term subluxation has been used in this title because it denotes forward displacement of the last lumbar vertebra on the sacrum without a defect of the interarticular part of the neural arch. Some authorities accept the term spondylolisthesis only when a neural arch defect is present, and describe those cases without such a lesion as subluxation despite the marked attenuation of the neural arch and the giving way of the lumbo-sacral joints. Another term, spondyloptosis (Neugebauer 1888), has also been used to describe the more severe type of displacement. The more extensive the study of the literature the greater becomes the confusion in the distinction between spondylolisthesis and subluxation, and eventually the conclusion must be that spondylolisthesis means nothing more than “ a slipping vertebra,” as its name implies and as Kilian originally described it in 1854, and that separation into spondylolisthesis and subluxation is false. In the study of a series of 319 cases of spondylolisthesis (Newman 1963) five groups were described. These groups were defined on the basis of clinical and radiological observations and of the findings at operation. Lumbo-sacral subluxation, of which the two main causative
