Objective: To investigate the risk factors of adjacent osteoporotic vertebral compression fracture(OVCF)in the treatment of OVCF, and to provide guidance for clinical practice. Methods: A retrospective analysis of percutaneous vertebroplasty(PVP) in the treatment of single OVCF and 168 patients who met the inclusion criteria of this study was followed up for at least 2 years to analyze the risk factors of adjacent vertebrae (age, gender, BMI, bone mineral density T value, fracture type, injected). The amount of bone cement, the distribution pattern of bone cement, the severity of preoperative fracture, the relationship of postoperative Cobb angle, and further establish the risk score of re-collapse. Results: This study found 41 patients (24.4%) with adjacent vertebrae fractures, BMI, bone mineral density T value, bone cement injection volume, bone cement distribution pattern and postoperative Cobb angle correction were significantly correlated with the occurrence of adjacent vertebrae refracture. Conclusion: According to BMI, bone mineral density T value, bone cement injection volume, the risk factor scores established by the distribution pattern of cement and the correction of postoperative Cobb angle can effectively predict the adjacent fractures after PVP.
