- 39. Apparatus for the distraction of tissue surfaces in a given direction, comprising a plurality of wafers stackable consecutively one upon another to form a column extending in the given direction, the wafers having top and bottom surfaces enabling them to move with respect to one another in a second direction generally normal to the given direction as a wafer column is formed, and the wafers having opposed leading and trailing ends so cooperatively beveled as to force the top surface of one wafer to engage and ride beneath the bottom surface of another wafer when the leading edge of one wafer is urged in the second direction against the trailing edge of another wafer.
- 72. Apparatus for the distraction of tissue surfaces in a given direction, comprising a guide track having an end portion insertable between the tissue surfaces, and a plurality of wafers configured to travel consecutively along the track to the end portion, the wafers and track being so configured as to form upon the end portion a stacked column extending in the given direction to distract the tissue surfaces.
