Pectus Carinatum

Pectus carinatum also called Pigeon chest, is a deformity of the chest wall in which the sternum and rib cartilage protrude outward. It is much less common than other chest wall deformities, occurs four times more often in boys than in girls and typically becomes more pronounced during the early growth of adolescence. It may occur as a solitary congenital abnormality or in association with other genetic disorders or syndromes.

Pectus carinatum can cause several symptoms, including chest pain, shortness of breath, fatigue and asthma symptoms. Patients may also experience negative psychological impact.The treatment options for pectus carinatum includes surgery and customized dynamic compressor brace.

The FMF Dynamic Compressor System

The FMF Dynamic Compressor System (DCB) was developed by pediatric surgeons Marcelo Martinez-Ferro and Carlos Fraire in Buenos Aires, Argentina.

The basic concept behind the FMF Dynamic Compressor System is to use the precise amount of pressure needed to reshape the chest without causing skin breakdown or so much discomfort that the child will not wear the brace. A special device measures the pounds per square inch that the brace exerts, which is adjusted monthly as the chest slowly assumes a normal shape.

In six years of treatment with 208 patients, Drs. Ferro and Fraire determined that keeping the starting pressures below 2.5 PSI helped avoid the sort of problems that often cause children to give up on treatment. During that time, more than half of their patients completed treatment and of those, 88.4 percent had results that were judged good to excellent in a double blind subjective scale. Average time for wearing the brace was just over 7 hours a day for around 7 months.

The FMF Dynamic Compressor System is not a good alternative for young people who require more than 7.5 PSI compression to achieve correction.
