How to Correct Pectus Carinatum

Pectus carinatum, also known as “pigeon chest,” is a congenital chest wall deformity characterized by anterior protrusion of the sternum, resembling the breastbone of a chicken or pigeon—hence its name. It is the second most common thoracic deformity after pectus excavatum, though less prevalent than the latter, with an incidence of approximately 1 in 1,000. The male-to-female ratio is about 4:1, and it accounts for 16.7% of all chest wall deformities. Symptoms typically manifest later in life, with over 50% of cases diagnosed after age 11. So, how is pectus carinatum corrected? Below, we address this question.

How to Correct Pectus Carinatum

1. Lifting Weights with Both Hands

Hold weights in both hands, clasp them together in front of your chest, then lift them upward and hold for several seconds before slowly lowering them. Maintain relaxed breathing throughout the exercise and repeat several times.

2. Supine Chest Expansion

Lie supine on a bed, grasp a resistance band or spring exerciser with both hands, and position your arms above your chest. Inhale deeply, then slowly pull the resistance band outward to both sides, hold for approximately three seconds, and exhale while returning to the starting position.

3. Standing Resistance Band Exercise

Grasp the handles of a resistance band with both hands, inhale, slightly bend your elbows, maintain this angle, and pull the band downward toward the front of your lower abdomen. Hold briefly for several seconds, then exhale while allowing your chest muscles to gradually return to their resting position.

Additional Information: Causes of Pectus Carinatum

1. Congenital Pectus Carinatum

This form primarily results from imbalanced development of the ribs and sternum—specifically, accelerated rib growth that pushes the sternum forward. Some affected children have a family history of the condition. Pectus carinatum may coexist with other congenital disorders, such as congenital heart disease, congenital diaphragmatic hernia, or congenital torticollis.

2. Acquired Pectus Carinatum

The vast majority of acquired cases are associated with rickets—specifically, vitamin D deficiency in children, which impairs calcium and phosphorus absorption and disrupts endochondral ossification.

The above outlines methods for correcting pectus carinatum. We hope this information proves helpful.
