What are the qualities of ideal suture material?

High tensile strength, predictable loss of tensile strength, inert, excellent handling (no memory and good knot security), inexpensive

Not one suture material has all of these qualities!!!

What is tensile strength in regard to suture material?

Amount of force (psi) that suture can withstand before breaking

What is memory in regard to suture material?

Ability/tendency of suture to return to its original package form

What is capillarity in regard to suture material?

Ability of suture to allow bacteria to wick to interior of strand

What are the characteristics of monofilament suture?

One strand, less traumatic to tissues, more memory, poor knot security, low capillarity

What are the characteristics of multifilament suture?

Composed of more than one strand that is twisted, braided, or sheathed

More traumatic, capillary action, flexible, no memory, good handling and knot security

What is natural suture?

Suture material derived from animal/plant sources

What origin of suture material has the strongest tissue reaction?

Natural suture, especially silk

What are examples of natural suture?

Silk, cotton, catgut, chromic

What is catgut suture derived from?

Sheep intestine

What is chromic suture material?

Tanned catgut with chromic salts

Is synthetic suture inflammatory?

No, little tissue reaction

What are examples of synthetic suture material?

Vicryl, Dexon, PDS, Prolene

What is non-absorbable suture?

Suture material that is not broken down by the body, has constant tensile strength, and can remain intact for up to 2 years

What are examples of non-absorbable suture?

Nylon, polypropylene, stainless steel

What is absorbable suture?

Suture that is broken down by the body, tensile strength decreased within 60 days

How does natural, absorbable suture break down?

By phagocytosis; strongest tissue reaction due to inflammation

How does synthetic, absorbable suture material break down?

By hydrolysis; least reactive with little inflammatory response

Suture Types

How is suture material sized?

Classified by thread diameter from 11-0 (thinnest) up to 7 (thickest). The system functions like a number line with zero as the midpoint: as the number before "-0" increases, the suture becomes thinner (e.g., 4-0 is thinner than 2-0), while for sizes 0 to 7, a higher number indicates a thicker suture
