Description
Jiasheng Chen and ten co-authors compare spine implants in the computer before any patient is involved. Their 2026 study models the rebuilding of a spine after a vertebra is removed whole to treat a tumor. Three reconstructions of the same gap were simulated: a custom 3D-printed prosthesis with an artificial pedicle, a stand-alone printed prosthesis, and the standard titanium mesh cage.
All three stiffened the segment sharply. The printed designs beat the cage in backward bending, cutting motion by fifteen and thirty-six percent. They also spread load more kindly. Stress on the neighboring bone surfaces fell by up to about half, and the prosthesis itself carried the least stress in the stand-alone printed model. The authors credit the printed parts' fit against the bone ends, and suggest the design lowers the risk of the hardware loosening or sinking over time.
