Q65-Q79: Congenital malformations and deformations of the musculoskeletal system
Q71: Reduction defects of upper limb
Reduction defects of the upper limb, grouped under the ICD-10 code Q71, represent a spectrum of congenital conditions where a part or the entire upper limb fails to form properly during embryonic development. These abnormalities are typically present at birth and can range from minor, such as a missing finger, to significant, like the complete absence of an upper limb. The cause of these conditions is often unknown but may be related to genetic factors, environmental influences, or a combination of both. Common symptoms across this group include physical deformities that affect the appearance and function of the arm, hand, fingers, or shoulders. It is important to note that these conditions do not progress or worsen over time, but the extent of the impact on a person's life can vary greatly depending on the severity of the defect.
