Foshion sutures include
Absorbable - Progressive loss of mass and/or volume of suture material does not correlate with initial tensile strength
● Breaking strength - Limit of tensile strength at which suture failure occurs
● Capillarity - Extent to which absorbed fluid is transferred along the suture
● Elasticity - Measure of the ability of the material to regain its original form and length after deformation
● Fluid absorption - Ability to take up fluid after immersion
● Knot-pull tensile strength - Breaking strength of knotted suture material (10-40% weaker after deformation by knot placement)
● Knot strength - Amount of force necessary to cause a knot to slip (related to the coefficient of static friction and plasticity of a given material)
● Memory - Inherent capability of suture to return to or maintain its original gross shape (related to elasticity, plasticity, and diameter)
● Nonabsorbable - Surgical suture material that is relatively unaffected by the biological activities of the body tissues and is therefore permanent unless removed
● Plasticity - Measure of the ability to deform without breaking and to maintain a new form after relief of the deforming force
● Pliability - Ease of handling of suture material; ability to adjust knot tension and to secure knots (related to suture material, filament type, and diameter)
● Straight-pull tensile strength - Linear breaking strength of suture material
● Suture pullout value - The application of force to a loop of suture located where tissue failure occurs, which measures the strength of a particular tissue; variable depending on anatomic site and histologic composition (fat, 0.2 kg; muscle, 1.27 kg; skin, 1.82 kg; fascia, 3.77 kg)
● Tensile strength - Measure of a material or tissue\'s ability to resist deformation and breakage
● Wound breaking strength - Limit of tensile strength of a healing wound at which separation of the wound edges occurs
