Retrospective Analysis of Outcomes Following Expandable Titanium Cage and Iliac Graft Applications in Patients Undergoing Corpectomy for Cervical Spinal Canal Stenosis

Introduction: This study aimed to compare the clinical and radiological outcomes of iliac crest autografts and expandable titanium cages in anterior cervical column reconstruction among patients undergoing cervical corpectomy for cervical spinal stenosis.Methods: A retrospective analysis of 93 patients who underwent anterior cervical corpectomy between 2016 and 2023 was conducted; 61 were treated with iliac grafts and 32 with expandable cages.Clinical efficacy was assessed using the modified Japanese Orthopaedic Association (mJOA) score, while radiological outcomes were evaluated by measuring cervical lordosis (C2-C7 Cobb angle), intervertebral height, and fusion status, three months post-surgery.Complications, operative duration, and revision surgery rates were also analysed.Results: Both the iliac graft and cage groups demonstrated significant postoperative improvements in mJOA scores (p
