Trigger fingers: A checkmark incision
MS Bell
In surgical release of trigger fingers both transverse and longitudinal
incisions are often used in the four fingers; however, in
the thumb, a longitudinal linear incision can be somewhat tight
and tethered and uncomfortable for many months. A transverse
incision runs the risk of potential damage to the superficial
underlying neurovascular bundles and gives less adequate
exposure to longitudinally release the flexor tendon sheath pulley.
A V-shaped incision for trigger thumbs is advocated by many
as the procedure of choice to avoid these two problems.
