Interbody fusion cages made of poly‐ether‐ether‐ketone (PEEK) have been widely used in clinics for spinal disorders treatment; however, they do not integrate well with surrounding bone tissue. Ti‐6Al‐4V (Ti) has demonstrated greater osteoconductivity than PEEK, but the traditional Ti cage is general...
