Various methods and suture patterns are described for repairing flexor / extensor tendons and their use varies by the surgeon’s preference. FiberWire’s superior strength and reliability makes FiberWire an ideal choice when performing a Suture Flexor/Extensor Repair. FiberWire is constructed of a multi-stranded, long chain, ultra-high molecular weight polyethylene (UHMWPE) core with a braided jacket of polyester and UHMWPE. This combination provides a high strength, soft suture with abrasion resistance that virtually eliminates suture breakage during knot tying and is found to be five times more abrasion resistant than standard polyester sutures.
