Fundamentals of Sutures, Needles, Knot Tying, and Suturing Technique

Suture and needles are the most essential equipment for the surgeon. Their structure and design have evolved thoroughly in the era of modern surgery. Suture varies based on its physical properties including material, construction, absorbability, size, tensile strength, length, and color. Similarly, needles vary in their point type, curvature, strength, length, and color. An array of combinations of sutures and needles has been created with specific surgical tasks in mind. While there is no ultimate suture that will work in any circumstance, certain guiding principles allow the surgeon to choose the best option. Our aim in this chapter is to provide information on the physical properties of suture and needles so that individuals feel comfortable calling for the proper suture for any surgical task.
