As with any running buried technique, this approach provides the benefit of permitting rapid placement of a long string of tension relieving sutures. The pulley effect of the multiple throws also permits effective closure of wounds under even marked tension.

That said, it is critical to focus on outstanding knot security, since the entire suture line is held in place by the knots at the beginning and end of the set of suture throws.

Adding an additional tacking knot when utilizing this approach is an option as well, as it may provide additional knot security. Alternatively, one could consider placing an additional knot or leaving a longer suture tail when utilizing this approach.
++
A theoretical benefit of the running approach is that there is less suture material left in situ, since the bulk of retained absorbable suture material is in the knots; as there are knots only at the beginning and end of the row of sutures, this technique theoretically decreases the risk of suture spitting and suture abscess formation.

Suture throws may be placed closer together toward the higher-tension areas at the center of the wound to permit greater mechanical advantage and to allow the pulley effect to have a more profound impact at the center of the wound. The throws may then be spaced farther apart toward the apices where the pulley effect is neither needed nor desired, allowing minimization of the quantity of retained buried absorbable suture material left in the wound.
