Club hand deformity is one of the congenital hand diseases. This deformity occurs as a result of some problems that occur while the baby is in the mother's womb.

There are two types:

  1.  Radial club hand: It includes the underdevelopment (hypoplasia) or absence of the radius and is accompanied by the disorder of the muscle structure that causes the hand to be bent from the wrist towards the thumb (radial deviation). The thumb may be absent or small (rudimentary), the muscles on that side may not be developed. This may be alone or may be part of a systemic disease or genetic syndrome (such as craniosynostosis, Fanconi anemia, Holt-oram syndrome). It depends on the accompanying conditions. Mild hypoplasia does not require treatment. Complete radial aplasia is performed by plastering, splint and surgical centralization in the first year to stretch the soft tissues. Centralization includes soft tissue release, reposition and stabilization of the hand on the tip of the ulna.
  2. Ulnar club hand: It occurs as a result of lack of development of tissues such as bone and muscle on the ulnar or little finger side of the hand. (Hypoplasia or absence of the ulna) Very often the radius is shortened and curved, finger deformities are common. Since unlar club hand can be found with very severe deformities, treatment should be directed accordingly.
