The use of titanium rods has been the gold standard for spinal fusion, but they pose a risk of stress shielding and require bone grafting for fusion. Polyetheretherketone (PEEK) rods have emerged as a promising alternative due to their radiolucency, biocompatibility, and superior mechanical properties.Objective: The purpose of this study is to evaluate the clinical efficacy of PEEK rods in lumbar fusion surgery compared to titanium rods.Methods: This will be a prospective randomized controlled trial. Patients with lumbar degenerative disc disease or spinal stenosis who require single-level or multi-level lumbar fusion surgery will be included in the study. They will be randomized into two groups: the PEEK group and the titanium group. The primary outcome measure will be the fusion rate, assessed by radiographic evidence of fusion at 12 months postoperatively. Secondary outcome measures will include pain intensity, functional status, and complications.Results: It is anticipated that PEEK rods will demonstrate comparable or superior fusion rates to titanium rods. Additionally, PEEK rods may result in reduced pain and complications compared to titanium rods.Conclusion: The use of PEEK rods in lumbar fusion surgery may offer advantages over traditional titanium rods. This study will provide valuable data on the clinical efficacy of PEEK rods in the context of spinal fusion surgery.
