Suture technic and suture-holding capacity. A model study and a theoretical analysis.

D E Holmlund

    American Journal of Surgery
    |November 1, 1977
    PubMed
    Summary

    Suture material strength depends on friction, fiber properties, knot security, and strand integrity. Optimal suture and tying techniques maximize material strength and allow for thinner strands.

    Area of Science:

    • Biomaterials Science
    • Surgical Technology
    • Textile Engineering

    Background:

    • Surgical sutures are critical for wound closure.
    • Understanding suture-holding capacity (SHC) is essential for optimal surgical outcomes.
    • Various suture materials and tying techniques exist, each with unique properties.

    Purpose of the Study:

    • To analyze the suture-holding capacity (SHC) of six representative surgical suture materials.
    • To evaluate the influence of different suture technics on SHC.
    • To identify key factors affecting suture strength and performance.

    Main Methods:

    • Six representative surgical suture materials were tested.
    • Three distinct suture technics were employed: single loop, far-and-near, and near-and-near.
    • Suture-holding capacity was measured and analyzed based on material properties and technics.

    Main Results:

    • SHC is influenced by the coefficient of friction between suture and tissue, fiber distensibility, knot-holding capacity (KHC), and untied strand strength.
    • KHC is most critical with the single loop technic and low friction.
    • The near-and-near technic yielded the strongest sutures for most materials, except Dexon, where far-and-near was superior.
    • High friction reduced the impact of knot strength on SHC for far-and-near and near-and-near technics.

    Conclusions:

    • Optimal selection of suture material and tying technic is crucial for maximizing suture strength.
    • Appropriate technics can leverage the full strength potential of suture materials.
    • The findings suggest that thinner strands can be effectively utilized with correct techniques.
