PDS (polydioxanone)
PDS (polydioxanone)
PDS I and II are very long-lasting monofilament absorbable sutures. They are useful
when long-term strength retention is critical. PDS II was developed as a better-handling alternative to PDS I, which was criticized for its less-than-ideal handling characteristics. It retains strength for an extended period of time, with 50% strength retention at 5 weeks, and may take more than 6 months to absorb.
Biosyn (Glycomer 631) Biosyn is another monofilament absorbable suture. It has very good handling characteristics and outstanding initial tensile strength. It retains its strength for at least 3 weeks and takes up to 4 months to absorb completely. If Biosyn is used for superficial closures, the undyed version may be preferable.
