Impact of Risser Stage on Pressure of Correction in Pectus Carinatum

Pectus carinatum (PC) is a deformity of the anterior chest wall which is a common pediatric condition, characterized by an idiopathic overgrowth of the costal cartilages resulting in protrusion of the sternum. Knowing factors influencing pressure of correction may lead successful treatment outcomes. In a study by Lee and colleagues investigating the effectiveness of the orthosis, it was found that patients with advanced Tanner stage of pubertal development had a longer time for correction of deformity. Martinez-Ferro et al proposed that pectus carinatum may return mildly, in approximately 10% of cured patients, particularly if they have been treated before pubertal growth spurts or in case they have cured very rapidly. To the best of our knowledge factors influencing pressure of correction and treatment outcomes after compressive bracing have not been investigated before. Our aim is to investigate impact of Risser stage on pressure of correction in PC.
