In brief
This study reports zero bar dislocation in 114 pectus excavatum patients using bilateral medial stabilizer placement during the Nuss procedure, with immediate return to full activities including sports. The modification achieved superior outcomes compared to standard lateral placement, with only 4% minor complications and no postoperative activity restrictions required.
- Bilateral medial stabilizer placement in Nuss procedure achieved zero bar dislocation in 114 patients over 7 years.
- Immediate return to full activities including sports did not increase bar displacement with medial stabilizer technique.
- Cryoanalgesia combined with medial stabilizers enabled unrestricted postoperative activity without compromising outcomes.
- Overall complication rate was only 4% (wound infections and hematomas), demonstrating safety of the modified approach.
- Single-bar technique with medial stabilizers may eliminate need for traditional postoperative activity restrictions.

Abstract
Purpose
The current standard method for pectus excavatum (PE) repair is the Nuss procedure. One major postoperative complication is the displacement of the implanted metal bar, which is used to remodel the chest wall. Blocking the possible ways that the bar can be displaced with the use of stabilizers and peri/intracostal sutures has reduced the incidence of bar displacement. Despite the modifications, bar dislocation is often reported. We adopted the medial position stabilizer placement method and imposed no postoperative restrictions. In this study, we analyzed the bar dislocation rate with this modification and concurrent postoperative full activity.
Methods
Nuss procedure modification where stabilizers are placed bilaterally in the medial location was done on patients irrespective of age and Haller index greater than 3.25. A single bar was used for all patients. Cryoanalgesia was performed on every patient. No postoperative restrictions were imposed on the patients. Full immediate activities, including sports, were allowed.
Results
114 patients (103 male, 11 female) were analyzed from 2016 to 2023. The median age was 15 years old. There was zero incidence of bar displacement. The combined incidence of other postoperative complications was 4%: 2 wound infections and 2 hematoma formations, both needing incision and drainage.
Conclusion
Bilateral medial stabilizer placement resulted in no incidence of bar dislocation. Return to immediate full activities after the Nuss procedure did not appear to increase the incidence of bar displacement if stabilizers were placed medially.
