Meromelia

Meromelia is a congenital disorder characterized by the partial absence of a limb or limbs. This condition can affect any of the four limbs of the body, and the degree of limb absence varies from individual to individual. The cause of meromelia is often linked to genetic factors, environmental factors, or a combination of both.

Causes

Meromelia can be caused by a variety of factors. These include genetic disorders, exposure to certain drugs or chemicals during pregnancy, or complications during pregnancy. Some of the known causes include:

• Thalidomide Embryopathy: This is a condition caused by the drug thalidomide, which was used to treat morning sickness in pregnant women in the 1950s and 1960s. The drug can interfere with the development of the limbs in the embryo, leading to meromelia.

• Roberts Syndrome: This is a rare genetic disorder that can cause abnormalities in the development of the limbs, including meromelia.

• TAR Syndrome: This is a rare genetic disorder that can cause the absence of the radius bone in the forearm, a condition known as radial aplasia. This can lead to meromelia.

Symptoms

The primary symptom of meromelia is the partial absence of a limb or limbs. The degree of absence can vary widely, from a missing portion of a limb to the complete absence of a limb. Other symptoms can include:

• Shortened limbs
• Missing fingers or toes
• Abnormalities in the bones of the limbs

Diagnosis

Meromelia can often be diagnosed before birth through the use of ultrasound imaging. After birth, a physical examination can confirm the diagnosis. In some cases, genetic testing may be used to identify the cause of the condition.

Treatment

The treatment for meromelia depends on the severity of the condition and the specific needs of the individual. Treatment options can include:

• Prosthetics: These are artificial limbs that can replace the function of the missing limb.
• Orthotics: These are devices that can support the function of the existing limb.
• Physical therapy: This can help improve mobility and strength in the affected limb.
