- Running sutures are useful for long wounds in which wound
tension has been minimized with properly placed deep sutures and in
which approximation of the wound edges is good. This type of suture may
also be used to secure a split- or full-thickness skin graft.
Theoretically, less scarring occurs with running sutures compared with
interrupted sutures because fewer knots are made with simple running
sutures; however, the number of needle insertions remains the same.
- Advantages
of the simple running suture include quicker placement and more rapid
reapproximation of wound edges, compared with simple interrupted
sutures. Disadvantages include possible crosshatching, the risk of
dehiscence if the suture material ruptures, difficulty in making fine
adjustments along the suture line, and puckering of the suture line when
the stitches are placed in thin skin.
