What is PDS II suture?
Polydioxanone (PDS II) is a synthetic, absorbable, monofilament suture made from a polymer of paradioxanone (Figure 2). It has greater initial tensile strength than polyglycolic acid and polyglactin 910 but has the poorest knot security of all the synthetic absorbable sutures.
What type of suture material is PDS?
Polydioxanone (PDS) or poly-p-dioxanone is a slowly absorbable monofilament suture composed of the polyester, poly (p-dioxanone). This is a monofilament with greater strength than monofilament nylon and polypropylene, and with less tissue drag than the multifilament materials.
What color is PDS suture?
PDS sutures also cause minimal tissue reaction. Polydioxanone suture is available in violet colour.
What is Polydioxanone used for?
Polydioxanone is used in the preparation of surgical sutures. Other biomedical applications include orthopedics, plastic surgery, drug delivery, cardiovascular devices, and tissue engineering [48,49].
What is polypropylene suture?
PROLENE Sutures (clear or pigmented) are non-absorbable, sterile surgical sutures composed of an isotactic crystalline steroisomer of polypropylene, a synthetic linear polyolefin. The suture is pigment blue to enhance visibility.
What is a #1 PDS suture?
PDS (polydioxanone suture), a new synthetic absorbable suture, was used in 21 patients undergoing cataract surgery. It still retains 25% of its tensile strength at 42 days but absorption takes 130-180 days.
How is polydioxanone made?
Chemistry. Chemically, polydioxanone is a polymer of multiple repeating ether-ester units. It is obtained by ring-opening polymerization of the monomer p-dioxanone. The process requires heat and an organometallic catalyst like zirconium acetylacetone or zinc L-lactate.
What is a PDO thread facelift?
A PDO thread lift is an FDA-cleared procedure that uses dissolvable sutures to tighten and reposition sagging skin. This procedure is less invasive than facelift surgery and usually performed in less than forty-five minutes.
Is polypropylene suture a nylon?
The results show that both sutures are capable of achieving excellent long-term patency (100%) of anastomosed sites. Polypropylene suture was equivalent to nylon in mechanical integrity of the anastomosis sites but was superior in handling, knotting, and biocompatibility.
