Abstract
Pectus carinatum is characterized by a protruding sternum. This deformity can be surgically corrected through the minimally invasive Abramson technique. In this procedure, a presternal metal correctional bar, secured to rib-attached stabilizers, is implanted to redress the sternum to a neutral position. To anticipate the intended position of the sternum, manual compression is applied over the sternal deformity. We describe a modified version of the Abramson procedure, encompassing a table-mounted PectusAssist™ System which generates a constant mechanical compression over the protruding sternum. The PectusAssist™ System, most importantly, eliminates the necessity of manually applying repetitive pressure on the deformity, and therefore maintains a more stable sternal position. This will ensure accuracy of the template used to bend the bar into its desired configuration. The modification we propose also simplifies presternal tunnel creation as the two bilateral retromuscular tunnels, that need to be connected presternally, are potentially better aligned due to a more stable and reduced position of the sternum. The PectusAssist™ System makes the procedure less labor intensive and reduces variability without interfering with the safety of the procedure. Therefore, we advise standard use of the PectusAssist™ System during minimally invasive repair of pectus carinatum by the Abramson procedure.
