Material & structure
Polyamide, monofilament. Blue USP 7/0–3+4 (EP 0.5–6), undyed USP 5/0–2/0 (EP 1–3).
Properties
Excellent glide properties and very high linear and knot tensile strength, even in fine thread diameters.
Use
Non-resorbable. Used for ligatures, general surgery, orthopaedics and plastic surgery – particularly suitable for skin sutures.
Resorbable sutures?
A suture's degradation rate is measured as strength versus half-life, so a figure of 5 days means at least 50% of the tensile strength remains after 5 days. The time until the suture has fully dissolved is usually much longer.
The times below are therefore half-lives.
