Achiria

Achiria is a rare medical condition characterized by the absence of one or both hands at birth. This condition is also known as Hand agenesis or Congenital hand absence.

Causes

The exact cause of Achiria is unknown. However, it is believed to be due to a combination of genetic and environmental factors. Some studies suggest that it may be associated with mutations in certain genes, such as the SHH gene, which is involved in the development of the limbs during embryonic growth. Environmental factors, such as exposure to certain drugs or chemicals during pregnancy, may also play a role.

Symptoms

The primary symptom of Achiria is the absence of one or both hands at birth. This can range from a complete absence of the hand to a partial absence, where only some of the fingers are missing. Other symptoms may include abnormalities in the remaining parts of the arm, such as a shortened forearm or a missing thumb.

Diagnosis

Achiria can be diagnosed during pregnancy through an ultrasound examination. This can reveal the absence of the hand or hands in the fetus. After birth, a physical examination can confirm the diagnosis.

Treatment

There is no cure for Achiria. Treatment focuses on helping the individual adapt to their condition and live a full and active life. This may involve the use of prosthetic devices, physical therapy, and occupational therapy. In some cases, surgery may be performed to improve the function of the remaining parts of the arm.
