IMPROVED STERNAL FIXATION IN THE CORRECTION OF PEDIATRIC PECTUS EXCAVATUM

Pectus excavatum is the most common congenital chest wall deformity; it is manifest by abnormal costal cartilage segments causing sternal depression and rotation. The most popular repair involves resection of the abnormal costal cartilage segments, followed by sternal osteotomy and fixation to the adjacent chest wall. Methods of sternal fixation have included metal bars and struts, K-wires, pins, sutures, synthetic mesh, vascularized rib struts, and large AO plates, but they have not included more recent rigid fixation technology. Current rigid fixation techniques allow incorporation of malleable, low-profile reconstruction plates that can be contoured to correct the three-dimensional aspect of these defects. Three pediatric patients are presented in whom plate fixation was utilized for sternal fixation. Current reconstruction plate technology provides an improved fixation alternative for the correction of congenital chest wall anomalies, as well as offering similar potential advantages for traumatic, oncologic, and reconstructive surgery of the thorax.
