Abstract: A bone trabecular fusion cage for implanting into an intervertebral disc is disclosed. The fusion cage includes a bone trabecular housing made of titanium alloy powder material with trabecular housing accommodation space therein. A side wall of the bone trabecular housing is provided with a plurality of pores, and sclerotin can grow into the bone trabecular housing through the pores to securely fix the bone trabecular fusion cage in the intervertebral disc; and a liner made of polyether-ether-ketone material and fixed in the accommodating space of the bone trabecular housing, wherein the polyether-ether-ketone liner gpores can provide good elastic modulus of bone. With the product of the present disclosure, bone implantation is not required, the patient recovers fast, and excellent fusion effect can be obtained.
