Abstract
A fusion implant apparatus for facilitating fusion of adjacent bone structures includes an implant member for positioning between adjacent opposed bone structures. The implant member defines a longitudinal axis and first and second longitudinal ends and has an outer wall dimensioned to engage the opposed bone structures upon positioning therebetween in supporting relation therewith. The outer wall includes at least one thread for facilitating positioning between the opposed bone structures. The implant member has an intermediate portion which defines a cross-sectional dimension transverse to the longitudinal axis which is greater than respective cross-sectional dimensions of the first and second longitudinal ends of the implant member.
