Minimally invasive pectus excavatum repair: migration of bar and ossification.

Minimally invasive repair of pectus excavatum is an effective treatment option, with satisfactory results. Nevertheless, complications may occur during bar removal. We describe the case of a 16-year-old boy operated on for pectus excavatum with the Nuss procedure, who developed bar migration into the rib, with ossification, making its removal very difficult.
