Abstract

The article compares the tensile strength and elongation at break of two commonly used nonabsorbable surgical sutures for skin, soft tissue, and surgical wound closure techniques: Silk (natural) and Nylon (synthetic), both with a suture size of 3/0, in three conditions: without a needle attached, with a needle attached, and after knotting. The article also presents the relationship between tensile strength and elongation at break of the sutures under these conditions across different suture lengths used for stitching (experimented with suture lengths of 115 mm, 120 mm, 125 mm, 130 mm, and 135 mm). The research results provide guidance for selecting appropriate sutures according to tissue types or specific suturing technique requirements, thereby supporting clinical decision-making regarding the choice of surgical sutures in medical practice.
