Which stitch requires a backhand technique?

The vertical mattress stitch is specifically designed to facilitate tension distribution across the wound edges, and it is performed using a backhand technique to achieve its unique configuration. This technique involves passing the needle through the tissues in a way that allows for better approximation of the skin edges and provides enhanced wound healing. The vertical mattress stitch not only secures the tissue effectively but also minimizes skin tension, making the wound less likely to break down.

In contrast, other stitches such as the figure of eight and horizontal mattress utilize different techniques and configurations that do not involve the same backhand method. While the figure of eight stitch resembles a figure-eight pattern for securing tissue, it does not specifically require the backhand technique. Similarly, a horizontal mattress stitch, while effective for closing larger wounds, uses a more straightforward approach without necessitating the complex maneuvering involved in the vertical mattress stitch. The buried knot option indicates securing a knot deep within tissue layers but does not specifically highlight the backhand technique typically associated with the vertical mattress stitch.
