Abstract:
Objective To investigate the related risk factors of bone cement leakage after percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) of osteoporotic vertebral compression fracture.Methods A retrospective study was made on 108 patients (114 vertebrae) undergone PVP and PKP between January 2008 and June 2014.There were 32 patients with cement leakage and 76 patients without cement leakage.Between-group differences were analyzed in terms of gender,age,number of one-time treated vertebrae,anatomic dissection,surgical procedures (PKP or PVP),integrity of the posterior vertebral wall,puncture approaches (unilateral or bilateral),technical level of surgeons and bone cement volume.Results Bone cement leakage occurred in 36 vertebrae (with the proportion of 31.6％).Cement leakage was associated with number of one-time treated vertebrae,surgical procedures,fractured condition,and bone cement volume (P ＜ 0.05),but not with gender,age,anatomical site of injury,puncture approaches,and technical level of surgeons (P ＞ 0.05).Conclusions Bone cement leakage after PKP or PVP correlated with number of vertebrae with one-time therapy,surgical procedures,fractured condition,and volume of bone cement.A good master of technical procedures and indications and suitable injection of high viscosity bone cement can help reduce the incidence of cement leakage.
