Types of Suture: Absorbable and Non-Absorbable Guide

Types of suture play a crucial role in modern surgical procedures by helping close wounds, promote healing, and reduce infection risk. Sutures are broadly classified based on their material, absorption rate, and structure. The two main categories are absorbable sutures and non-absorbable sutures, each used for specific clinical needs.

Absorbable sutures are designed to break down naturally in the body over time and do not require removal. Common examples include Vicryl suture, Chromic Catgut, Plain Catgut, and PDS suture. These sutures are commonly used for internal tissues, muscle layers, and subcutaneous closure where long-term support is not required.

Non-absorbable sutures remain intact until they are removed by a healthcare professional or left permanently in the body. Popular non-absorbable suture types include Silk suture, Nylon suture, Polypropylene (Prolene), and Polyester sutures. They are often used for skin closure, cardiovascular surgery, and orthopedic procedures.

Sutures can also be classified as monofilament sutures, which have a smooth surface and lower infection risk, or multifilament sutures, which offer better knot security but may harbor bacteria. Choosing the correct type of suture depends on wound location, tissue type, healing time, and surgical technique.

Understanding the different types of suture materials helps surgeons ensure optimal wound healing, minimal scarring, and improved patient outcomes.types of suture
