The OC OsteoBraid™ Loopin is a closed-loop suture that comes with a loop at one end. It allows for easier suturing as the single tail of the suture can be passed through the tissue, and then simply hooked through the loop to create stitches. This method is especially useful for creating uniform stitching and knotless suturing. It can also be used as a suture shuttle for passage of traction sutures through bone tunnels.
