Answer

Compared with running (continuous) sutures, interrupted sutures are easy to place, have greater tensile strength, and have less potential for causing wound edema and impaired cutaneous circulation. Interrupted sutures also allow the surgeon to make adjustments as needed to properly align wound edges as the wound is sutured. A 2019 study suggested that high-density suture spacing (approximately 5 mm apart) could improve early scar formation, but noted that placing sutures farther apart (approximately 10 mm) results in fewer puncture wounds, decreases tissue trauma, saves surgical time, and conserves suture material. [3]

Disadvantages of interrupted sutures include the length of time required for their placement and the greater risk of crosshatched marks (ie, train tracks) across the suture line. The risk of crosshatching can be minimized by removing sutures early to prevent the development of suture tracks.
