Vertebral body augmentation for spine-related diseases has the advantages of minimally invasive surgery,obvious postoperative pain relief,and quick postoperative recovery compared with open surgery.It can quickly reconstruct spinal stability,relieve pain,and improve patients' quality of life.Intraoperative injection of bone cement into the diseased vertebral body carries the risk of bone cement leakage during the process.Knowing well the complications is helpful to the timely clinical treatment so as to avoid delays,and understanding the risk factors can facilitate targeted measures to prevent leakage during surgery.Therefore,to understand the consequences of bone cement leakage,leakage incidence rate,related risks factors and preventative measures is conducive to clinical treatment and surgery safety.The authors discuss the complications and risk factors related to bone cement leakage after vertebral body augmentation,in order to deepen the understanding of bone cement leakage,provide reference for clinical work,and improve the safety of surgery.
