Sutures are used by doctors to approximate the edges of a wound to give it a chance to heal without leaving a big scar. The materials used for this purpose are of many types and have many different properties. There are absorbable (will get absorbed by tissue enzymes and won’t need removing) and non-absorbable (will need to be removed) suture material. The suture material can also be divided by their filament size: monofilament sutures (one filament/fine) or braided sutures (braided together threads for better strength). Sutures can also be synthetic material or natural. Types of available absorbable sutures include: Gut (monofilament), Polydioxanone (synthetic monofilament), monocryl (synthetic, monofilament) and Vicryl (braided). Types of no absorbable sutures include: Nylon (monofilament), Prolene (monofilament), Silk (braided, natural) and polyester (braided, synthetic).
