Implant Materials for Anterior Column Reconstruction of Cervical Spine Tumor

Abstract

The spine is the most common site of bone metastases. Many cancer patients will ultimately develop spinal metastatic disease with symptomatic epidural spinal cord compression. At present, the main treatment for cervical spine tumors is surgical resection combined with postoperative radiotherapy. Implant materials for cervical spine anterior column reconstruction need to meet amounts of different properties, such as biocompatibility, bioactivity and the ability to maintain long‐term mechanical strength. The selection of different materials determines the surgical efficacy and prognosis of patients to a certain extent. This article provides an overview of a variety of implant materials used for anterior column reconstruction after cervical spine tumor resection, introduces and analyzes their properties, advantages, disadvantages, derivatives, and applications in clinical practice, and looks forward to the future development of implant materials.

Comparison of clinical efficacy of 3D-printed artificial vertebral body and conventional titanium mesh cage in spinal reconstruction after total en bloc spondylectomy for spinal tumors: a systematic review and meta-analysis

“…In the field of spinal surgery, 3D-printed artificial vertebral bodies (AVBs) have a personalized design that can achieve a complete match and closely fit the upper and lower vertebral bodies, reducing the probability of subsidence ( 10 ). Because 3D-printed AVB can simulate the normal human anatomical structure, its reconstruction after spinal tumor resection has more biomechanical characteristics than conventional TMC, and the prosthesis is made of titanium alloy, which has good biocompatibility ( 11 ).…”
