What suture size is appropriate for lower-extremity wounds?

• A. 3-0
• B. 4-0 or larger
• C. 2-0
• D. 5-0

Answer: (B)

Lower-extremity wounds bear more tension from movement and thicker underlying tissue, so the skin closure must be strong enough to hold edges together during healing. A thicker suture for the skin provides greater tensile strength and reduces the risk of tearing or dehiscence when the leg moves or swells. Very fine sutures, while great for low-tension areas where cosmetic appearance matters (like the face), are more prone to breakage on the leg under stress. In practice, you choose a stronger, less-tine suture for leg closures, rather than the finest gauges.
