- W4237510588 abstract "RECOGNITION in the living subject of anatomical variations in the spine, which are many and have been known for centuries, is ultimately based upon X-ray evidence. Practically all writers seem to agree that comparatively few variations appear in the cervical and dorsal region compared to the greater percentages that occur in the lumbar and sacral segments. The presence of these changes in the vertebral column when traumatism or pseudotraumatism has occurred, may be mistaken for traumatic as well as non-traumatic lesions of the spine, or other pathologic conditions which may be due to trauma or other causes. Many years ago we heard much about railway spine. To-day this same term, used first by Erichsen in 1868, has insinuated itself among a larger class of people, including the medical profession, as the so-called industrial spine. The occurrence of actual or alleged injuries is of great interest to all medical men, especially to the surgeon and roentgenologist. Anomalies and anatomic variations are of particular interest when one is endeavoring to determine the true etiology and prognosis of back sprains or other injuries to the spine. Vertebral anomalies were noted in 1,122 roentgenograms of the lumbar vertebræ and sacrum. This number represented the negative genito-urinary examinations in a consecutive series of approximately 8,000 patients, who were subjected to X-ray examinations in the Scott and White Clinic. During this period, comparatively few roentgenograms were made of the cervical and dorsal spine except following alleged injuries, therefore it will be impossible from our studies to give any definite data regarding the exact percentage of occurrence of vertebral anomalies in these regions. That these cases were sent to the X-ray department for genito-urinary examinations would indicate that the discovery of these anomalies was quite accidental as they could not possibly have any bearing on the well-being of the individuals, and their occurrence is probably of scientific value only. In this connection, I should like to stress that we should continue to report every possible anomaly. I suggest that we speak of these as normal variations of the spine instead of congenital anomalies, because our studies as well as those of many others seem to indicate that individuals having these peculiarities of development are in a way just as normal as those having the standard pattern. I should like to stress also, first, that one should always endeavor to determine if there has been sufficient trauma to produce the alleged injury, and, second, if the violence or trauma was directed in such a manner as to produce the particular lesion. It must be recognized that any attempt to classify accurately the anomalies of the lumbar region from a study of this region alone is unreliable. As an example, 50 of the 1,122 roentgenograms studied showed an increase to 6 in the number of lumbar vertebræ, and, in 13 cases, 4 lumbar vertebræ were noted." @default.
