Suture and Suture Materials

Surgical Sutures are normally classified into two types, absorbable and non-absorbable. They can also be classified based on their construction, either mono-filament or multi-filament, coating provided, absorption profile and also whether they are made from natural or synthetic materials. Sutures can also be classified according to their usage e.g. cardiovascular sutures, ophthalmic sutures, general sutures, orthopaedic sutures etc.

Absorbable sutures include :- Polyglycolic Acid sutures, Polyglactin 910 , Catgut, Poliglecaprone 25 and Polydioxanone sutures.

Non-Absorbable sutures include :- Polypropylene sutures, Nylon (poylamide), Polyester, PVDF, silk and stainless steel sutures

Monofilament sutures include :- Polypropylene sutures, Catgut, Nylon, PVDF, Stainless steel, Poliglecaprone and Polydioxanone sutures.

Multifilament or braided sutures include :- PGA sutures, Polyglactin 910, silk and polyester sutures.
