Step 5.
Pass Free Suture End Up Through
the Suture Loop
For the left index finger to bring the entire suture
end up (arrow) through the loop, the left hand
must release its grip of the suture. During this
interval, tension cannot be maintained continually
on the first throw, allowing the first-throw suture
loop to widen, with subsequent partial separation
of the wound edges.
Step 6.
Advance First Single-Wrap Throw
to Wound Surface
With the suture ends grasped in the palms of the
surgeon’s hands, the tips of the thumbs and index
fingers position the suture ends in a direction (arrows)
perpendicular to that of the wound. The surgeon
applies constant tension to the suture ends, which
advances the first, single-wrap throw of the square
knot to the surface of the wound. Advancement of
the first throw is complete when the divided skin edges
of the mid-portion of the wound are approximated.
