Abstract:
1. An orthopedic implant comprising an impacted mesh body defining an interior chamber, said body comprising: a first end including a first support band extending about a first axis and defining a first opening into said interior chamber and defining a first end surface; and a second end opposite said first end and including a second support band extending about the first axis and defining a second opening into said interior chamber and defining a second end surface; and a longitudinal wall extending along a second axis substantially orthogonal to the first axis and between opposite transverse end walls, said longitudinal wall integral with said first and second support bands to define a one-piece, unitary body, said unitary body having a cross-sectional thickness measured orthogonal to the first axis at said first and second support bands that is greater than a cross-sectional thickness of said longitudinal wall, said longitudinal wall including an exterior surface extending between said first end surface and said second end surface, and wherein said first and second support bands provide the implant with an uninterrupted support band surface extending continuously about an outer perimeter of said first and second ends and flush with said exterior surface of said longitudinal wall and which does not extend beyond said exterior surface of said longitudinal wall in a direction orthogonal to the first axis, said longitudinal wall including a plurality of openings formed therethrough defining a grid pattern; and wherein said first end surface defined by said first support band and said second end surface defined by said second support band each comprise an arcuate end surface having a convex curvature extending along the second axis and between said opposite transverse end walls, said arcuate end surfaces of said first and second support bands defining a maximum height of the implant along the first axis positioned between said opposite transverse end walls that is greater than a height of a bone cavity to inhibit expulsion of the implant from the bone cavity.
