What is the purpose of bumpers on tension sutures?

Bumpers on tension sutures are specifically designed to prevent heavy sutures from cutting into the skin. This is particularly important in surgical settings where sutures are under significant tension. When sutures pull tightly on tissue, they can create pressure points that may lead to tissue necrosis or ulceration if not properly managed. The bumpers, which are typically made of soft material or are designed to distribute tension more evenly, act as a cushion or barrier between the suture and the delicate skin. This allows for effective wound closure while minimizing the risk of damage to the surrounding tissue.

The other options, while they might address other aspects of suture care or performance, do not directly relate to the primary function of bumpers. For instance, while bumpers may indirectly influence knot visibility or the overall strength of a suture line, their main role is to protect the skin from the pressure and sharp edges of heavy sutures.
