ZipFix cable-tie implants offer a novel, feasible method for stabilizing Nuss bars in pectus excavatum repair, significantly reducing bar displacement complications.
Area of Science:
- Thoracic Surgery
- Minimally Invasive Surgery
- Biomaterials in Medical Devices
Background:
- Bar displacement is a major complication of the Nuss procedure for pectus excavatum.
- The Nuss procedure is a common surgical technique for correcting pectus excavatum.
Purpose of the Study:
- To report a novel bar fixation method using ZipFix implants.
- To evaluate the feasibility and outcomes of ZipFix for Nuss bar stabilization.
Main Methods:
- A case series of 20 patients undergoing the Nuss procedure with ZipFix stabilization.
- The study period was from July 2015 to September 2020.
Main Results:
- 34 ZipFix implants were used in 20 patients, with most receiving two implants.
- One asymptomatic bar displacement and two wound infections were reported.
- All patients achieved full correction without recurrence of chest wall deformity.
Conclusions:
- The ZipFix technique for Nuss bar fixation is feasible.
- This method shows promise in managing pectus excavatum repair complications.
