Pdf Summary

The DYNACORD suture represents an advanced technology in soft tissue repair designed to minimize suture laxity and improve surgical outcomes. It features a unique silicone/salt core structure that responds dynamically to hydration. When exposed to physiological fluids, the salt particles within the silicone core elute and absorb fluid, causing the core to radially expand by approximately 20%. This expansion pushes the braided suture strands apart, compressing the weave and leading to an axial shortening of about 10% in the suture length.<br /><br />This mechanical behavior allows the suture to tighten after being placed, effectively reducing slack and maintaining tension in double row fixation techniques commonly used in soft tissue repairs. The ability of the DYNACORD suture to self-adjust helps ensure a secure tissue approximation and potentially enhances healing by maintaining consistent tension at the repair site.<br /><br />The design and mode of action of DYNACORD are supported by multiple US patents (US8870915, US9757120, and US9757121), highlighting its innovative approach to soft tissue suturing. The suture is typically hydrated in a 37°C saline bath for 24 hours to simulate post-implantation conditions, demonstrating the expansion and shortening effects crucial to its function.<br /><br />Overall, DYNACORD sutures offer a promising solution for surgeons aiming to improve soft tissue repair durability by reducing suture loosening through a patented core expansion mechanism activated by fluid absorption.
