Limb Abnormalities

Limb Abnormalities

Skeletal limb abnormalities are problems in the bone structure of your arms or legs. They can affect a part of your limb or the entire limb. Usually these problems are present at birth and sometimes babies are born with abnormalities in more than one limb.

Certain diseases or injuries can disturb the normal growth of your bone structure and lead to skeletal abnormalities as well.

Symptoms of Limb Abnormalities

If you’re born with a skeletal limb abnormality, outward symptoms can be obvious, such as:

• a limb that isn’t fully formed or is missing a component
• one leg or arm that is shorter than the other
• legs or arms that aren’t in proportion with the rest of your body

In the case of acquired limb abnormalities, you might not have any external symptoms. Some common signs of an acquired limb abnormality are:

• one leg appears to be shorter than the other leg
• pain in your hip, knee, ankle, or back
• one shoulder looks slumped in comparison to the other
• unusual walking gait such as a limp, rotating your leg in an unusual way, or walking on your toes

How Do Doctors Diagnose Limb Abnormalities?

If the abnormality is present when you’re born, it usually can be diagnosed immediately with a physical examination.

An acquired skeletal abnormality requires a fairly extensive examination. This procedure includes viewing your medical history, taking a physical exam, and measuring your limbs. X-rays, CT scans, and other types of medical imaging also can be used to view underlying bone structure and diagnose abnormalities.

What Treatments Are Available?

There are three primary goals of treatment for congenital limb abnormalities, including:

• encouraging development of the affected limb
• improving the appearance of the affected limb
• helping you adapt to day-to-day issues that may be caused by the abnormality

Your doctor will help you decide the best type of treatment for your specific condition.

Supportive Devices

Your doctor may prescribe an artificial arm or leg, known as a prosthetic limb. It functions in place of a normal limb.

In some cases, your affected limb may be present but weakened. An orthotic brace or splint may be used to support your affected limb so it can function normally.

Occupational or Physical Therapy

In some cases, your doctor may recommend occupational therapy or physical therapy to help exercise and strengthen your affected limb.

Surgery

Sometimes surgery is necessary to repair an abnormality in your leg’s structure. Two types of surgery are epiphysiodesis and femoral shortening. Epiphysiodesis is a carefully timed procedure to stop the normal growth of one leg so that the shorter leg can reach an equal length. Femoral shortening is a procedure where part of the femur, or thigh bone, is removed.

Limb Lengthening

Your doctor might recommend elongating a short limb through a gradual process called limb lengthening. For this procedure, your doctor will cut your bone and use an external device to gradually increase the length of your leg over the course of several months to a year. This procedure can be painful and has a higher potential for complications than other treatments.

Long-Term Outlook For Limb Abnormalities

As a child with a skeletal limb abnormality, you may face a variety of physical and emotional difficulties. Your experience will depend on where the abnormality is located and how severe it is. Possible issues include:

• problems with developing motor skills and other physical milestones
• limitations in sports participation or other activities
• being teased or excluded because of differences in your appearance
• needing help in personal activities, such as eating or bathing

Ongoing medical treatment for skeletal limb abnormalities can assist you in gaining optimal functioning and independence. Many people with some type of limb deformity are able to live productive and healthy lives.

Prevention of Limb Abnormalities

There is no certain way to prevent skeletal limb abnormalities from occurring. Instead, the focus is on early detection and treatment.

Pregnant women can decrease chances of limb abnormalities in their babies by taking a prenatal vitamin that includes folic acid. It’s also recommended that pregnant women avoid tobacco and alcohol use.
