This document discusses suture materials used in surgery. It begins by defining sutures and their purpose in surgery. It then lists the goals of suturing and the ideal properties of suture materials. The document categorizes suture materials based on source (natural, synthetic, metallic), structure (monofilament, multifilament), absorption rate (absorbable, non-absorbable), and coating. Common examples are provided for each category. Key differences between monofilament and multifilament sutures are outlined. Properties like strength, memory, and knot security are discussed in selecting the appropriate suture material.
