Abstract:
With development of modern medicine and tissue engineering,spinal implants have been commonly used in clinic for spinal diseases. According to post-implant functional features,the spinal implants are divided into static fixation system (pedicle screw,steel plate and intervertebral fusion) and dynamic fixation system (artificial intervertebral disc and artificial nucleus pulposus). In addition,biocompatibility and mechanics performances are involved in the system. Implant loosening and breakage are primary complications following surgery. Based on rich experience of treatment with various spinal implants and research advances of spinal biomechanics,implant selection is a complex problem and related to many factors. Thus,careful protocol before implantation,biomechanical factor evaluation and their relationships with patient occupation,sex,age and living habit are important.
