What is pectus carinatum?


Pectus carinatum (PC) is a deformity of the chest which causes the breastbone (sternum) to be pushed out. The condition is also known as "pigeon chest" or "chicken breast." It is less common than pectus excavatum, in which the sternum is pushed in or depressed. Pectus carinatum is thought to affect approximately 1 in 2,000 people in the United States.

PC can be present at a young age, but commonly becomes more evident during puberty at the time of rapid growth. Researchers have not identified the cause of pectus carinatum, but it likely has a genetic component, since as many as 1 in 4 patients have a family history of the condition. Pectus conditions occur more frequently in males than females by a 4:1 ratio.

There is a high correlation between pectus carinatum and scoliosis, but one doesn’t necessarily cause another. Some people may have both characteristics, and some may have just one or the other.

The pectus team at Children’s Mercy are recognized leaders in treating chest wall deformities and are one of the highest volume centers in the country. This means our experience has made us experts in treating a wide range of pectus cases.

What are the symptoms of pectus carinatum?

Children with pectus carinatum do not typically have any significant physical symptoms other than the outward “pigeon chest” appearance. Some patients have chest pain. One of the more common problems associated with pectus carinatum is body image issues. Children are often embarrassed about the appearance of their chest and may avoid activities or social interaction for these reasons.

Can I play sports if I have pectus carinatum?

Yes! People with pectus carinatum should continue participating in all activities they find enjoyable. Some symptoms may be exacerbated with physical activity but the activity itself does not pose a health risk. Pay attention to activities that seem to cause problems and ask your pectus professional if there is any relation.

What are the treatment options?

Nonsurgical treatment with bracing has become the standard of care for correction of pectus carinatum and has been shown to have excellent outcomes. The ideal age to begin bracing is around 11-14 years old dependent on maturity and severity of the pectus carinatum.

In mild cases, observation or no treatment may be recommended. The carinatum will likely continue to enlarge as the child grows during adolescence.

The need for surgery is rare. If bracing has not been successful or those with severe or unusual anatomy, an operation to remove the abnormal rib cartilages may be recommended.

Pectus carinatum brace

Wearing a chest brace for pectus carinatum is an effective treatment because children’s growing bodies are very flexible during childhood and adolescence. That adaptability means children’s chests can more easily be molded into the correct shape as they grow.

Children’s Mercy uses a customized brace, called the dynamic compression system (DCS). The DCS is an external chest compression brace that applies concentrated pressure to the area of the chest with the greatest protrusion. This state-of-the-art brace corrects an abnormal chest shape the way orthodontics corrects crooked teeth. The brace “remodels” the chest by applying gentle pressure to gradually correct the area of protrusion. Worn continuously and adjusted regularly (typically every 6 to 8 weeks) the brace allows the chest to slowly redevelop into a more normal shape. Once skeletal maturity has been reached, the cartilage in the chest and pectus carinatum will stiffen, and the child will no longer be a candidate for nonsurgical repair with using the brace.

What does the brace look like?

The brace made from a light-weight aluminum that is worn around the chest. It provides pressure from both the front and back to direct the breastbone to neutral position. There are cushioned pads that contact the child’s chest. The main pad is positioned to press against the breastbone. The band is adjustable.

Under normal, loose-fitting clothing, the brace is not easily noticeable.

How long does the brace need to be worn?

When a child first begins wearing the brace, he or she should do so for as many hours of the day as possible (23 out of 24 hours a day). Except for during bathing and sports, your child should wear the brace all day and during the night.

Most children will need to wear the brace full time for about 4 to 6 months and be able to decrease the wear to ~2 times per week until skeletal maturity has been reached for a total time in the brace of about 2 years, though that period can vary. After the chest develops a more normal shape, the brace wear will be slowly tapered to reduce the amount of time that your child wears the brace, much like you wear a dental retainer after orthodontic braces are removed.

Is the brace painful or damaging to the skin?

No, the brace should not be painful to wear. Most children say their chest is slightly sore after they first begin wearing the brace, especially on the front of the chest, but ibuprofen (Motrin) or acetaminophen (Tylenol) can ease the discomfort. Minimal redness at the contact sites from wearing the brace is normal. Some patients prefer to wear a thin, tightly-fitting, moisture-wicking shirt underneath.

How much does a Pectus Brace cost?

The estimate of prices and traditional charges for professional service are listed on our Pectus Brace billing information page. Every child is different; therefore, there may be services outside of the pricing performed at the time of service and are not included in this summary.

Once your child has been identified as a pectus brace candidate, the clinical team will reach out to the Children’s Mercy Financial Clearance department to pursue preauthorization if your insurance company will cover this service.

Brace recommendations

  • Wear the brace as often as possible, preferably 23 out of 24 hours per day, excluding showering, swimming or sports. Remember: the brace only works if you wear it! The more you wear it, the faster it will work!
  • Check for skin blanching each time you remove the brace. If the skin does not blanch, leave it off for an hour and check again. Do not replace the brace if the skin will not blanch. Call surgery clinic, (816) 234-3199 for appointment.
  • You may be sore for the first few days. Take Ibuprofen as needed for pain. Ease your way into wearing it.
  • If you are ill with a cough or have an asthma flare up, take frequent brace breaks for deep breathing/coughing.
  • If you wear a shirt under your brace, make sure to pull the wrinkles out.
  • You will want to clean the brace as least once per week or as needed. You may use alcohol or household cleaner wipes or plain soap and water. Do not immerse in water!
  • If a screw is loose, use a Phillips screwdriver to tighten it. Please do not adjust the brace except for the straps. The straps can be adjusted at home as needed.
  • Try to sleep in the brace. You may feel more comfortable with extra pillows or an egg crate mattress for support.
  • Perform the prescribed exercises as instructed and use good posture for the best result.
