Trulife Pectus Carinatum Brace is a prefabricated bracing solution for chest wall deformities, including pigeon chest. Features a low-profile design with an anterior panel (4-1/4"W x 3-1/2"H) for a posterior-directed force, a posterior panel (4-3/4"W x 6"H) for an anterior-directed force, and four lateral padded panels that contour around the chest. Panels are made from a low-density polyethylene that is flexible enough to easily conform around the patient's chest to create an intimate and concealed fit. Over time, the patient's body heat helps to mold the plastic panels around the chest for an even better custom fit. Covered in a washable foam liner for additional patient comfort. Ratchet closure and bendable metal components for an adjustable fit. One size fits most up to a 35" chest circumference.What is Pectus Carinatum? Pectus carinatum (PC) is an anterior chest wall deformity associated with abnormal growth and development of the costal rib cartilages and sternum that is observed as an outward protrusion, tilt, or convexity on the anterior chest wall and often includes the sternum and associated ribs. The PC prominence may be either asymmetrical or symmetrical. Accurately identifying the type of Pectus Carinatum deformity is a crucial step in predicting the success of orthotic outcomes. PC orthosis design is based on Wolff ’s Law that when healthy bone and cartilage are loaded with a constant and increasing force, they will adapt, strengthen, and gradually remodel. A PC orthosis has two opposing forces, one directly over the apex of the prominence and one on the thoracic spine. Over time, this continuous force arrests further anterior cartilaginous growth and gradually remodels the rib cage into a more normal, flattened shape. The PC orthosis is worn until skeletal maturity is reached.
