New suture anchor made of VESTAKEEP® PEEK

(PresseBox) ( Essen, )
With the development of the knot-free Plug-n-Twist suture anchor, IST Innovative Shoulder Technology AG and Argomedical AG have created another addition to their successful product portfolio. For the first time, the new suture anchor was made from VESTAKEEP® PEEK from Evonik Industries. Plug-n-Twist anchors are impact anchors for the second row in minimally-invasive arthroscopic sutures on the shoulder's rotator cuff.

In addition to a titanium version, the anchor is now also available in the same product design in a version made of PEEK, a non-resorbable plastic. The use of the new anchor does not require any changes to intraoperative procedures. The long suture threads of the first medial anchor row are pulled through the eyelet in the tip of the Plug-n-Twist anchor and are then fixed in place using the anchor's pressure against the bone. In the so-called interference procedure, the suture threads used for repairing the defect are tightly fitted between bone and anchor for a permanent press fit. Thanks to the rounded tip of the implant, there is significantly less soft tissue irritation when the anchor is inserted in the shoulder.

The innovative design of the Plug-n-Twist anchor allows it to be easily inserted and, if necessary, removed by means of unscrewing.

"PEEK has proven successful as an implant material. It is biocompatible and ideally suited for medical imaging procedures because it does not generate any artifacts," says Dr. Christoph Sternberg of Etzelclinic in Pfäffikon (Switzerland). "Another advantage of using PEEK as an anchor material is its easy handling in any later revision surgery, in case the anchor is severed with a bone saw and has to be removed."
