This study reviews the results of our previously described modification of the minimally invasive (Nuss) procedure for correction of pectus excavatum. It utilizes a subxyphoid incision with central fixation to maximize safe bar passage and minimize bar displacement.
Consecutive patients corrected with the modified Nuss procedure between 2010 and 2015 form the basis of this study.
During the study period, 73 patients had correction of their pectus excavatum by the modified Nuss procedure, utilizing subxyphoid incision and central fixation. Average age was 14.3 (range 8–19). 54 patients were male, 19 female. The average Haller index was 4.3 (range 3.2–7.2). No episodes of cardiac perforation, hemothorax or significant pneumothorax were recorded. Bar displacement occurred in two patients (2.7%) with one late recurrence after bar removal.
Our modification of the Nuss procedure is effective at preventing intrathoracic complications and cardiac perforation. Central fixation had a lower rate of bar displacement compared to published reports. Additional efforts are needed to further reduce bar displacement.
