    The approach to wound closure (Table) is influenced by multiple factors, including time elapsed since initial injury, degree of contamination, amount of tissue damage, wound location, extent of tension or dead space, and the patient’s general and local health.

    Open wound management can be facilitated via skin-stretching devices such as tensioning sutures. Skin has inherent elastic properties that allow approximation of wound edges over small distances. Skin can also extend its natural boundaries through a phenomenon known as mechanical creep.

    When tension is applied gradually over 2 to 4 days, randomly oriented dermal collagen and elastic fibers straighten and elongate, becoming more parallel to tension lines and lengthening the skin. Over time, less force is required to maintain the collagen fibers in their stretched position because the skin’s elastic fibers lose their natural recoil (ie, stress relaxation).

    The goal of tensioning sutures is to take advantage of these properties to stretch the skin and hasten wound closure. In addition, tensioning sutures and similar devices hold dressings in place and prevent retraction of skin edges.
