Comparative Analysis of Anterior Corpectomy versus Laminoplasty Efficacy in Radiological Outcomes for Cervical Spondylotic Myelopathy Treatment

Objective This study aims to assess the radiological outcomes of anterior corpectomy compared to laminoplasty in treating Cervical Spondylotic Myelopathy (CSM), focusing on postoperative improvements in key imaging metrics. Materials and Methods A retrospective cohort analysis evaluated 45 patients diagnosed with CSM who underwent anterior corpectomy (21 patients) or laminoplasty (24 patients). Radiological outcomes were measured by comparing preoperative and 6-month postoperative CT and MRI scans, focusing on the Harrison posterior tangent curve, sagittal vertical axis (SVA), cranial tilt, cervical tilt, Jackson stress curve and cobb angle. Results The study found statistically significant improvements in Harrison posterior tangent curve, SVA and cranial tilt measurements for both surgical methods. No significant differences were observed between the two surgical techniques when comparing the ratio of post-operative to pre-operative values. Conclusion Both anterior corpectomy and laminoplasty were effective in altering radiological parameters in the treatment of CSM, with no significant difference in efficacy between the two techniques. These findings underscore the importance of a tailored approach to surgical intervention in CSM, with decisions based on individual patient anatomy and clinical presentation. Further studies with larger patient populations are needed to confirm these results and establish standardized radiological benchmarks for surgical outcomes in CSM treatment.
