![]() Suture size definitions are currently based on diameter, a consistent measure for circular monofilament sutures, but not for braided or noncircular sutures.Ĭopyright 2010 American Society for Surgery of the Hand. The optimal suture size to use is CV-3, which has a soft and manageable pliability and great strength, all with the size of about a 20 prolene suture. Failure to meet the United States Pharmacopeia standards for suture diameter is declared in the product information sheet, although surgeons may not be aware of these size variations. ![]() After relating knotted tensile strength to cross-sectional area, Fiberwire was 10% stronger than Prolene, and 25% stronger than Ticron.įiberwire is not only stronger, but also larger than other sutures in the same or even higher suture size category. The 4-0 Fiberwire cross-sectional area was also greater than that of 3-0 Ticron and Prolene (p <. 001), which in turn were larger than 3-0 Prolene (p <. The 3-0 Fiberwire sutures had greater cross-sectional area than the 3-0 Ticron sutures (p <. Prolene and Ticron cross-sections were circular. ![]() Ten strands of each suture material and size had a single throw knot placed, and they were loaded to failure in a micromechanical tester. These were examined by scanning electron microscopy and digitally analyzed for cross-sectional areas. This study sought to define differences in cross-sectional area and knotted tensile strength among Fiberwire, Prolene, and Ticron sutures.įive strands, each of 3-0 and 4-0 Prolene, Ticron, and Fiberwire sutures, were embedded in polymethylmethacrylate and sectioned in a linear precision saw to obtain 10 cross-sections of each material and size. Flexor tendons should be repaired with suture material strong enough to permit early motion and small enough for the resulting knot to allow unimpeded tendon glide and healing. ![]()
