CINERADIOGRAPHY IN NORMAL AND ABNORMAL WRISTS

Abstract
Preliminary cineradiographic studies of normal and abnormal wrist conditions have been made. Subluxated naviculars, "clicking" wrists, and ununited navicular fractures have been studied. The dynamic alterations differ from patient to patient in conditions which seem similar on routine roentgenograms. The information gained from cine examinations should be a valuable adjunct in pre-treatment diagnosis and planning. The concept of casting navicular fractures to allow both unrestricted thumb motion and unlimited pronation and supination has been explored and is felt to be valid. Future studies of congenital abnormalities, of traumatic and rheumatoid wrist problems, and of adequacy of immobilization by various casts are in progress.
