Abstract:Adjacent segment degeneration (ASD) refers degenerative disorder of the adjacent disc following spinal fusion, with many risk factors, such as advanced age, overweight, previous degeneration of the segment, osteoporosis, sagittal spine-pelvis imbalance, choice of surgical techniques, number of segments of intraoperative decompression and fusion, destruction extent of anatomical structure involved. The incidence and morbidity of ASDs after lumbar fusion remain relatively high at present, and how to effectively prevent and treat ASDs af- ter lumbar fusion is a hot and difficult topic in the research of spinal degenerative diseases. Therefore, we reviewed the literature reports on adjacent segment degeneration over the past 10 years, aiming to provide further theoretical reference for clinical practice and reduce the inci- dence of adjacent segment degeneration after lumbar fusion to improve the long-term clinical effect of lumbar fusion.
