Clinical Features and Roentgenograms of Symbrachydactyly

Abstract

Müller and Blauth have suggested that short webbed fingers, atypical cleft hand and acheiria develop as morphological variants of symbrachydactyly. The clinical features and roentgenograms of our 76 patients were analysed. The common features of all types of symbrachydactyly were that all cases were unilateral, various degrees of bone hypoplasia existed in the affected limbs, and in every grade there were some cases with pectoral muscle absence. There seems to be a successive process of formation of atypical cleft hand. Monodactyly and peromelia occur as a result of more severe reduction occurring in the central finger rays of symbrachydactyly of short finger type.
