| There are many incision and
flap designs for syndactyly release. Common patterns involve a
proximal flap to surface the web space and paired zig zag dorsal and
palmar flaps which interdigitate on the same digit. A potential
pitfall is that the surgeon planning the flaps can not see both sides
of the finger at the same time, and it is possible to plan flaps which
are reversed and exactly the opposite of what was intended. The
simple way to check and prevent this possible error for zig zag flap
designs is that the zigs and zags should look the same, not reversed when
the hand is flipped palmar and dorsal. This is an example.
