16. Evaluation of the cage subsidence performance of three porous lateral cage designs

Interbody cage subsidence remains a major complication after lumbar spine fusion surgery, particularly in lateral or other procedures that rely on indirect decompression. Porous cages are believed to reduce the risk of cage subsidence. Multiple porous cage designs exist, including 3D printed (3DP) titanium cages with body lattice and microporous endplates, 3DP titanium cages with a truss structure, and PEEK cages with surface porosity. Currently, there is a lack of carefully-controlled biomechanics studies to evaluate their relative performance.
