Types of Suture and Their Common Medical Uses

Types of suture describe the various surgical threads used to close wounds, incisions, and surgical openings. Sutures are essential in medical and surgical care, as they help tissues heal correctly while reducing the risk of infection and excessive scarring. The choice of suture depends on the location of the wound, tissue strength, and healing duration.

Sutures are mainly classified as absorbable sutures and non-absorbable sutures. Absorbable sutures naturally break down in the body over time and are commonly used for internal tissues and organs. These sutures do not require removal and are ideal for areas that heal quickly. Examples include catgut and synthetic absorbable materials.

Non-absorbable sutures remain in the body until removed or may be left permanently when long-term support is needed. Materials such as silk, nylon, and polypropylene are frequently used for skin closure and orthopedic procedures.

Another way to classify sutures is by structure. Monofilament sutures consist of a single smooth strand that lowers infection risk, while multifilament sutures are braided, offering better handling and knot stability. Understanding suture types and materials helps ensure safe wound closure and effective healing.
