title: A positioning fixture for L-shaped rotating undercutting microknives.
abstract: A simple, inexpensive device which controls the insertion, positioning and withdrawal of cortical undercutting microkinives is described. The device aids the "rolling" insertion of an L-shaped microknife which produces a minimum amount of overlying tissue damage while it holds the knife steady during undercutting and allows the blade to be withdrawn by way of the same track through which it was inserted.
