Suture Materials

Question 1

Tendency for suture to return to its original shape

Answer 1

Memory

Question 2

Degree that suture will deform w/o breaking and maintain its shape

Answer 2

Plasticity

Question 3

Ability to resist deformation and breakage and the stress at which deformation or breakage occurs

Answer 3

Tensile strength

Question 4

Force necessary for a knot to slip

Answer 4

Knot strength

Question 5

Degree of fluid transferred by the suture as a result of absorption

Answer 5

Capillarity

Question 6

Single stranded suture that is less pliable and more susceptible to damage

Answer 6

Monofilament

Question 7

Multiple braided/twisted strands w/greater strength and pliability but increased tendency for bacterial colonization

Answer 7

Multifilament

Question 8

Proteolytic breakdown very fast (gone in 2-3wk), so don’t use this suture in organs

Answer 8

Catgut

Question 9

Twisted suture made from small intestinal submucosa of sheep or intestinal serosa of cattle

Answer 9

Catgut

Question 10

Multifilament suture with minima breakdown during its first two weeks of placement

Answer 10
