City, Iowa On the basis of Kirmissons definition of club hand asany permanent deviation of the hand to the forearm, theclassification of Lodi distinguishes dorsal and palmarflexion, radial or ulnar abduction: talipomanus fiexa varaor valga, talipomanus extensa vara or valga. But for prac-tical purposes it is much better to adopt Whitmans dis-tinction of cases of distortion by abnormal restraint andpressure in utero, and cases of deformity associated withdefective development of radius and ulna. Of the latterclass the vast majority show deviation to the radial side,due to partial or total defect of the radius. Of 114 casesreported by Antonelli, 56 were unilateral and the rest bi-lateral cases. Absence of the radius was observed in 44cases. Absence of the radius is therefore the most impor-tant single feature in congenital club hand deformities. Although ulnar deviation is not very uncommon amongcongeni
