Q74: Other congenital malformations of limb(s)

Q74.8: Other specified congenital malformations of limb(s)

A malformation may, for example, involve bones being missing or there being supernumerary bones present. The bones may also have an altered shape or be positioned differently to each other than they are normally. The affected part of the body may therefore be differently shaped than normal. The person may be able to use the affected part of the body to a limited extent or not at all.

While developing in the womb, many different types of tissue develop in the body. The organs and body parts develop out of the various types of tissue. A child’s development in the womb being disrupted can cause malformations. Some malformations are hereditary. This means that other family members can also be affected. However, a malformation may also be caused by a harmful influence during pregnancy. They include, for example, maternal or child illnesses.
