What are Limb Deficiencies?
   Upper and lower limb reduction defects occur when a part of or the entire arm (upper limb) or leg (lower limb) of a fetus fails to form completely during pregnancy. The defect is referred to as a "limb reduction" because a limb is reduced from its normal size or is missing.
