This study was prompted by a desire to know more about the appearance of the developing elbow. Certain facts stand out in bold relief to those who interest themselves in injuries about the elbow, or any other joint, in the young. Some of the points to be mentioned are self-evident, and yet a survey of the literature, or the comparative absence of such a literature, makes their mention of value.
This is only one of a series of studies which will be carried out in a like manner on other joints.
In order to study the subject in a systematic manner, I have divided the paper into four parts:
A review of the literature.
Observations on a series of normal elbows at various ages.
Descriptive findings of the individual roentgenograms.
Clinical experience in the treatment of injuries of the elbow.
I. A REVIEW OF THE LITERATURE
