Abstract
An apparatus and method for distracting, in a given direction, and supporting two tissue surfaces is provided. A plurality of wafers are consecutively inserted using a wafer insertion apparatus between the two tissue surfaces to create a column of wafers. A detachable wafer assembly is provided that includes a base wafer initially associated with a track assembly of a wafer insertion apparatus. The base wafer is dislodged from the track assembly so that the base wafer is left within the distraction site as the track assembly is removed. A top cap wafer is provided that is situated at the top of the wafer stack, in which the top cap wafer is larger than the remaining wafers to form a gap surrounding the stack to receive biologic material.
