The presentation that I1 made a year ago led to the conclusion that vertebral epiphysitis is a disease entity, and that it may be a cause of spinal deformity. That the former is a reasonable conclusion is becom-is more and more evident from a perusal of the French,2 German3 and Italian4 literature in which there has recently appeared a pertinent series of independent observations leading to the same belief. A number of authors have doubted that vertebral epiphysitis is a cause of spinal deformity. It is my purpose here to stress this phase of the subject and to bring more data to bear on this question.
Scheuermann5 in his original article on kyphosis dorsalis juvenilis raises the issue as to whether vertebral epiphysitis is a cause or a result of spinal deformity. He answers it in the affirmative without presenting definite evidence in proof thereof.
