Radial Dysplasia

Nathanael Olson et al.

Excerpt

Radial club hand is a term describing a group of complex congenital malformations of the radial side of the forearm. It comprises a spectrum of conditions that varies widely from thumb hypoplasia to an absent radius and first ray and includes hypoplasia of the associated muscles, ligaments, tendons, nerves, and blood vessels. Other terms that refer to the same condition are radial dysplasia, radial longitudinal deficiency, and radial ray deficiency.

Jean-Louis Petit described the first case of radial club hand in 1733, who documented a case of a newborn male with bilateral absent radii. Kato, in 1923 reviewed 250 cases of radial clubhand and can be considered the first attempt at a comprehensive study of the condition.
