X. instrument-tie technique — square knot (1=1)
formation of the first throw (cont’d)
Step 1.
Position the Needle Holder
The instrument tie is performed with a
needle holder held in the surgeon’s right
hand.
The left hand holds the fixed suture end
between the tips of the thumb and index
finger. The needle holder is positioned
perpendicular to and above the fixed suture
end. By keeping the length of the free suture
end relatively short (<2 cm), it is easy to form
(arrow) suture loops as well as to save suture
material. Because the needle holder passes
the free suture end through the suture loop,
knot construction can be safely accomplished
without detaching the needle from the fixed
suture end.
