Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to determine whether sternal reconstruction using the ZIPFIX system compared to standard wire cerclage could improve bone healing, patient function, and decreased postoperative pain.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Despite a longer time for bone healing and functional recovery, median sternotomy is still the most common approach in cardiac surgery. Sternal closure has traditionally been wire cerclage using stainless steel wires, however, new sternal fixation devices have been developed to improve sternal union. Rigid sternal fixation, although very costly, has demonstrated to be superior to standard wire cerclage both in clinical and biomechanical studies. Although improved sternal healing was observed with rigid plate fixation in a randomized controlled trial in high risk patients, the wound complication rate with plate fixation was almost double that of wire cerclage albeit not statistically significant.

A novel sternal closure system denoted the sternal ZIPFIX system (DePuySynthes, Companies of Johnson and Johnson, West Over, PA, US) is biocompatible Poly-Ether-Ether-Ketone implant that was developed for fast and reliable sternal fixation following median sternotomy. First published case series utilized the sternal ZIPFIX System demonstrating effective sternal stability at 30 days. Another study has demonstrated no significant difference in the incidence of sternal wound infection following the ZIPFIX system compared to standard wire cerclage while Stelly et al., 2015 demonstrated reduced risk of deep sternal wound infection for patients using ZIPFIX. The ZIPFIX system demonstrates a higher resistance of fatigue failure and has a larger implant-to-bone contact area compared to stainless steel wires thereby reducing the risk of bone cut through. Placement of the cable ties are done similar to wire cerclage thereby not affecting time for sternal closure and training.

The objective of this study is to determine whether sternal reconstruction using the ZIPFIX system compared to standard wire cerclage would improve bone healing, patient function, and decrease postoperative pain.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Steel Wires

In this arm, patients will have their sternum closed with steel wires.

Group Type ACTIVE_COMPARATOR

Steel Wires

Intervention Type DEVICE

Control: Steel wires (device) are selected for sternal closure after surgery. Currently, most patients who have a sternotomy during cardiac surgery have their sternum closed with steel wires.

ZipFix Sternal Closure System (Plastic Cables)

In this arm, patients will have their sternum closed with the ZipFix system.

Group Type EXPERIMENTAL

ZipFix Sternal Closure System

Intervention Type DEVICE

Treatment: ZipFix system (device) are selected for sternal closure after surgery. These plastic cables can also be used to close the sternum during bypass surgery.
