Abstract:[Objective] To explore the risk factors related to bone cement leakage secondary to percutaneous vertebroplasty (PVP) for Kümmell’s disease in the elderly. [Methods] A retrospective study was conducted on 106 elderly patients (134 vertebrae) who underwent PVP for Kümmell’s disease in our department from May 2018 to May 2021. Based on whether or not bone cement leakage happened second- ary to PVP, the patients were fall into the leakage group or non-leakage group. Univariate comparison and binary multiple logistical regres- sion were conducted to search the factors related to the bone cement leakage in PVP. [Results] Of the 106 patients (134 vertebrae) , 57 verte- brae proved of bone cement leakage, accounting for 42.54% (57/134) . In term of univariate comparison, the leakage group was of significant- ly more severe Kümmell’s staging, higher ratio of lumbar involved in the location, higher ratio of vertebral fissures found in vertebral injury typing, greater bone cement volume used, and higher ratio of diffused distribution of bone cement than the non-leakage group (P<0.05) . As results of logistic regression, diffused distribution of bone cement (OR=4.450, 95% CI: 1.989~9.957, P<0.001) , the lumbar involved in frac- ture site (OR=4.380, 95% CI: 1.880~10.202, P=0.004) , greater bone cement amount injected (OR=3.896, 95% CI: 1.133~13.401, P<0.001) and the fissure-like lesion in vertebral body injury (OR=3.518, 95% CI: 1.239~9.995, P<0.001) were independent factors related to bone ce- ment leakage secondary to PVP for Kümmell’s disease in the elderly. [Conclusion] Fracture site in lumbar, diffused distribution of bone ce- ment, more amount of bone cement, and fissure-like lesion are the risk factors for bone cement leakage in PVP, which should be paid atten- tion to for prevention of bone cement leakage in clinical setting.
