This stitch is easy and most versatile but can cause 'railroad track' scarring.

• A. Simple Interrupted
• B. Vertical Mattress
• C. Halsted
• D. Continuous Running

Answer: (A)

Simple interrupted stitches are the workhorse of wound closure: easy to learn, adaptable to different wound shapes, and you can adjust tension edge by edge since each stitch is tied separately. The trade-off is that every stitch leaves a puncture in the skin, so closing a longer wound with many of these can create a row of small puncture marks along the scar. When these marks line up, they resemble railroad tracks, especially in skin with noticeable healing. This technique is favored for its versatility and simplicity, but in cosmetic areas you might choose methods that minimize surface punctures, such as subcuticular or buried sutures, to reduce track-like scarring. The other patterns are more specialized—vertical mattress for better edge eversion and tension distribution, Halsted as a variant of interrupted with deep bites, and continuous running for speed—so they don’t align with the combination of broad applicability and potential track marks described here.
