Pectus Bar Dislocation: Comparison Between Three Different Stabilization Techniques Adopted in a Single Centre
Topic overview
Single-center study of 468 patients comparing three pectus bar stabilization techniques shows bridge fixation eliminates bar dislocation (0%) compared to single-bar fixation (4.8%) and no stabilizer (8.8%). Bridge fixation is now the preferred stabilization method for MIRPE procedures.
Key takeaways
- Bar dislocation after MIRPE occurred in 8.8% without stabilizers, 4.8% with single-bar fixation, and 0% with bridge fixation technique
- Bridge fixation eliminated bar dislocation entirely in 205 bars over 10 years, making it the preferred stabilization method
- Dislocation defined as bar rotation >30° or lateral displacement >1.5 cm; occurred in 4.1% overall across 733 bars in 468 patients
- Any stabilization technique significantly reduces dislocation risk compared to no stabilizer in pectus excavatum repair
