Single Surgeon Experience of Adjacent Segment Disease and Related Risk Factors Following Posterior Decompression and Fusion in Lumbar Degenerative Disorders

Background and Aim: This study aims to evaluate the frequency of adjacent segment disease (ASD) its risk factors following posterior decompression fusion in lumbar degenerative disorders. Methods Materials/Patients: retrospective cohort was performed by reviewing records patients with spinal degeneration disorders who underwent surgery needed reoperation from 2013 2019. The participants were divided into two groups, including ASD non-ASD patients, compared terms age, sex, BMI, smoking, level, surgical indications, follow-up times, laminectomy, cross-link device usage, imaging findings, terminating L1, L5 S1, reoperation. Results: Out a total 277 candidates, 181 met inclusion criteria. In gender distribution, 43.3% male 56.7% female. median age 54 years group 48 group. six five Forty (22.1%) developed during this period. final analysis showed significant relationship between indication for reoperation, repeated surgery, use, L1. Conclusion: High body mass index, aging, canal stenosis, laminectomy at upper unit, stenosis imaging, L1 vertebrae are considered ASD.
