  A topologically minimal surface may be isotoped into a normal form with
respect to a fixed triangulation. If the intersection with each tetrahedron is
simply connected, then the pieces of this normal form are triangles,
quadrilaterals, and helicoids. Helical pieces can have any number of positive
or negative twists. We show here that the net twisting of the helical pieces of
any such surface in a given triangulated 3-manifold is bounded.
