The design and biomechanical study of the 3D-printed implanted cervical vertebral cage

This study demonstrates that the 3D-printed implanted cervical vertebral cage, used with monosegmental slot-expansion decompression, provides a biomechanical stability profile comparable to traditional ACDF, while offering greater subsidence resistance than partial corpectomy. These biomechanical findings suggest that the novel 3D-printed cage design may serve as a stable alternative for slot-expansion decompression. Further in vivo and clinical studies are warranted to confirm its long-term performance.
