Last week, the Altons discussed less invasive methods of wound closure off the grid like steri-strips, butterfly closures, and medical or industrial glues. Those are great for minor injuries, but they aren’t solid enough to keep some wounds, say over a joint, closed. For that, you need staples or sutures. It’s not hard to learn how to use these items, but how much do you know about the different types of suture materials available. What do you use internally and what do you use on the skin?
