[The differential diagnosis of posttraumatic ossifications in the area of the elbow joint in children].

Clinico-roentgenological observations of 64 patients aged from 4 to 14 years with posttraumatic ossifications in the elbow joint area, of whom 25 were operated upon, enabled the authors to compare the data obtained with the well-known signs of osteogenesis of another etiology. The case history and x-ray examinations are thought by the authors to be the most important methods allowing the nature of this osteogenesis to be differentiated. The main distinctive signs of the posttraumatic ossifications are the development of their roentgenological stages in the special chronological succession.
