Radial club hand or radial dysplasia describes a very rare congential failure of formation of preaxial structures in the upper limb. At its extreme, the most obvious abnormality is that of the skeleton with a hypoplastic or absent radius. However, all soft tissues may be affected.

It may be sporadic, associated with a syndrome or the result of exposure to an external teratogen.

Surgical treatment is usually commenced within the first few years of life and multiple procedures are typically required for more extreme dysplasia.
