- Abstract: BACKGROUND:Lumbar decompression and fusion is the most effective surgical method to treat lumbar degenerative spondylolisthesis.In recent years,the sagittal balance of the spine has been widely considered the key factor to adjust the outcome of spinal surgery,and factors that can affect the sagittal balance of the spine indirectly affect the surgical effect and prognosis. OBJECTIVE:To summarize the risk factors that can affect the sagittal balance of the spine during decompression and fusion due to lumbar spondylolisthesis,and play a certain reference role in the surgical treatment of lumbar spondylolisthesis. METHODS:With"lumbar spondylolisthesis,the sagittal plane balance of the spine,surgical treatment,risk factors"as the Chinese search terms,and"lumbar spondylolisthesis,sagittal balance,risk factor"as the English search terms,PubMed,Springer,ScienceDirect,Wanfang,VIP and CNKI were searched respectively.The focus of the search was from January 2010 to January 2023,and a few classic long-term articles were included.Preliminary screening was conducted by reading the title and abstract.After excluding repetitive research in Chinese and English literature,low-quality journals and irrelevant literature,67 articles were finally included for review. RESULTS AND CONCLUSION:(1)Degenerative lumbar spondylolisthesis is an important factor causing spinal canal stenosis and lumbar instability,and is the main cause of low back pain and intermittent claudication.Lumbar decompression,fusion and internal fixation is an effective way to treat degenerative lumbar spondylolisthesis.(2)In the past,the treatment of degenerative lumbar spondylolisthesis with decompression,fusion and fixation focused on thorough exploration and release of nerve roots,reduction of spondylolisthesis and solid internal fixation,but less attention was paid to the balance of sagittal plane of the spine.(3)With the popularization of lumbar decompression,fusion and internal fixation,complications caused by the sagittal imbalance of the spine gradually increased,resulting in poor prognosis of patients and even increased risk of secondary surgery.(4)Previous studies have only discussed the correlation between lumbar sagittal plane parameters and spinal sagittal plane balance,but have not in-depth studied the relevant factors causing spinal sagittal plane imbalance.(5)Our results show that open lumbar fixation and fusion,complete reduction of spondylolisthesis,selection of thicker pedicle screws,selection of larger fusion cages,and autologous bone transplantation are beneficial factors for maintaining sagittal balance.The higher the number of fusion segments,the higher the level of fusion segments is,which is a risk factor for sagittal plane imbalance.
