ABSTRACT
Objective At present, the mainstream surgical mode and the gold standard for the treatment of spine related diseases are still the intervertebral fusion with the intervertebral implantation of the intervertebral fusion device.The intervertebral fusion device routinely used in clinical practice cannot degrade in vivo after implantation, resulting in lifelong foreign body.High elastic modulus also leads to osteoporosis in adjacent vertebral bodies, which leads to implant sinking, stress shielding and'pseudomorphism'of fusion.The ideal biodegradable synthetic intervertebral fusion cage can be progressively degraded and eventually replaced by new bone, which has the advantages of elastic modulus close to cortical bone, good biocompatibility, X-ray permeability and good initial mechanical strength.In this paper, animal analysis of biodegradable intervertebral fusion cage, clinical effect analysis, current shortcomings and future trends were reviewed.
