Classification

Authoring team

One commonly used system for classifying radial club hand was described by Bayne and Klug in 1987:

  • type 1: short distal radius; radius shorter than ulna but normal form
  • type 2: hypoplastic radius; hypoplastic radius but proximal and distal epiphyses are present
  • type 3: partial absence of radius; distal part of the radius is absent
  • type 4: total absence of radius

Type 4 is the most common, followed by type 1 and then type 3.
