I. INTRODUCTION

Radio-ulnar synostosis, or congenital synostosis of the proximal ends of the radius and ulna, also sometimes called "congenital pronation," is a condition rarely found in one or both forearms of which the most obvious symptom is an inability to hold the hand supine; i. e., . . .

Footnotes
This study was begun in 1921 in collaboration with Dr. Henry Ling Taylor, at that time associated with the Hospital for Crippled and Ruptured, New York. Many circumstances have led to delay in publication: the necessity for prolonged field work; the pressure of other work previously begun. At last, when the analysis was nearly completed, came the serious illness followed by the death, of Dr. Taylor, in consequence of which the senior author has been forced to assume unexpected responsibility of the results.

This study was initiated by a series of cases that came to the clinic of Dr. Taylor, who has provided clinical descriptions of each propositus. The detailed study of the family history in these cases was made by Miss Louise A. Nelson of the Eugenics Record Office of the Carnegie Institution of Washington, Cold Spring Harbor, N. Y. The literature on the subject was looked up and abstracted by Miss Mabel L. Earle of the Eugenics Record Office. For the general discussions and the final form of the whole, C. B. Davenport, Carnegie Institution of Washington, is responsible. Especial thanks are due to Dr. D. D. Ashley for introducing us to the Pa. family (No. 11), and for the use of the roentgenograms relating thereto.
