Q73: Reduction defects of unspecified limb

Q73.1: Phocomelia, unspecified limb(s)

The arms and legs develop in the first few weeks of pregnancy. This development can be disturbed for various reasons. This may be the case with certain congenital diseases. Taking certain medication during pregnancy can also adversely affect the development of the arms and legs.

The bones in your arms or legs have not developed properly. This disruption in development results in the hands being right on the shoulders or the feet being right on the hips.
