The modern era of correction of pectus excavatum (PE) started in 1949 where Ravitch published the his first paper [1]. Since several modifications to the technique were published, but it was the standard way to correct PE until Nuss orally presented his first work in 1997 and published it in 1998 [2]. This minimally technique changed the strategy for correction and seems now to be the standard technique for surgeons who correct PE. This paper dealed with 45 patients who were corrected through a 10-years course. The age group was from 1 to 15 years and at that time it was thought that the technique could only be used in children and adolescents because the rigidity of the chest in adults was too high. With the growing experience of the technique it has been shown that even patients in the fifties and sixties might be corrected by the Nuss-procedure [3, 4]. The original technique prescribed that the bar length should be from the mid axillary line on each side. The first operations were done without scope assistance but to make the intervention safer using of the thoracoscope is now mandatory. One of the problems with the technique was the risk of rotation of the bar. This was reduced by first adding a stabilizer, then fixing the stabilizer to the bar and finally using several circumcostal sutures around the bar and rib on the opposite site of the stabilizer. These reduced the risk from around 15 to 1 % [5]. Later the use of a shorter bar has been published and this change has shown the same low risk of rotation [6, 7]. Using the shorter bar is easier, using shorter time in the OR, gives the same good cosmetic result and is as stable as using the long original bar.
