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.

A implant removal tool for a tibial baseplate. The implant removal tool includes an adapter having conjugated adapter teeth, a first adapter part, and a second adapter part. The first adapter part supports a cutting guide of the implant removal tool that is integral with the first adapter part, and the second adapter part is slidely coupling with the first adapter part allowing a relative translation between the first and the second adapter part.
