Surgical suture

<p>A surgical suture, also known as a stitch or stitches, is a <a href="/facts/Medical_device/uzUHp474">medical device</a> used to hold <a href="/facts/Tissue_(biology)/H7CpML7A">body tissues</a> together and approximate wound edges after an injury or surgery. Application generally involves using a <a href="/facts/Sewing_needle/Vy0HPS3W">needle</a> with an attached length of <a href="/facts/Thread_(yarn)/3RfyulKB">thread</a>. There are numerous types of suture which differ by needle shape and size as well as thread material and characteristics. Selection of surgical suture should be determined by the characteristics and location of the wound or the specific body tissues being approximated.
</p><p>In selecting the needle, thread, and suturing technique to use for a specific patient, a medical care provider must consider the <a href="/facts/Tensile_strength/Cv2jPplR">tensile strength</a> of the specific suture thread needed to efficiently hold the tissues together depending on the mechanical and shear forces acting on the wound as well as the thickness of the tissue being approximated. One must also consider the elasticity of the thread and ability to adapt to different tissues, as well as the memory of the thread material which lends to ease of use for the operator. Different suture characteristics lend way to differing degrees of tissue reaction and the operator must select a suture that minimizes the tissue reaction while still keeping with appropriate tensile strength.
