Abstract
The concept of “numerical variations” encompasses deformities that differ from the normal development of five independent finger rays. They occur as plus or minus variations. A large number of these poly- or oligodactylies can be deduced from an overextensive or incomplete differentiation in width; consequently they appear as partial or total “partitions” or “fusions” of single skeletal rays. W. Müller (1937) demonstrated the mutuality in morphological appearance for these plus or minus variations, using the picture of the more or less peripherally opening “prong”. Identical forms within a single ray (in poly- and oligodactylies) can be present. The difference between such recessive and excessive forms lays only in the direction of the deformity. When systematized from a teratologic point in view, one notices in oligodactylies a line of progression by lack of differentiation in width (fushion, proximal skeletal aplasia) from central to distal segments; in polydactylies, on the other hand, excessive differentiation (partitioning) occurs from distal to central segments.
