Sutures Flashcards
What is memory in suturing?
Tendency for suture to return to its orginal shape
What is plasticity?
degree that suture will deform without breaking and maintain its shape
What is tensile strength?
ability to rsist deformation and breakage and the stress at which deformation or breakage occurs
What is knot strength?
for necessary for knot to slip
What is capillarity?
degree of fluid transferred by the suture as result of absorption
Describe suture size
