Abstract
An interbody spacer for spinal fusion surgery includes first and second opposite side walls that have open-cell metal foam at upper and lower faces, and a three-dimensional lattice disposed between open-cell metal foam at the upper and lower faces. The open-cell metal foam is in communication with the three-dimensional lattice so that bone growth can enter the three-dimensional lattice from the open-cell metal foam. The interbody spacer may be formed by additive manufacturing.
