Abstract Objective The purpose of this research is to evaluate the risk factors and incidence of pulmonary cement embolism (PCE) during percutaneous vertebroplasty (PVP) or kyphoplasty (PKP) for osteoporotic vertebral compression fractures (OVCFs) based on postoperative computed tomography (CT). Methods A total of 2344 patients who underwent PVP or PKP due to OVCFs in our spine center were analyzed retrospectively. According to the detection of postoperative pulmonary CT, the patients were divided into two groups: pulmonary cement embolism group (PCE group) and non-pulmonary cement embolism group (NPCE group). Demographic data in both groups were compared using the χ2 test for qualitative data and the unpaired t test for quantitative data. Multiple logistic regression analysis was carried out to identify risk factors that were significantly related to the PCE resulting from cement leakage. Results PCE was found in 34 patients (1.9% 34/1782) with pulmonary CT examination after operation. There was no statistically significant difference in the parameters such as age, gender, body mass index (BMI), and cement volume in the two groups. Patients with three or more involved vertebrae had a significantly increased risk to suffer from PCE than those with one involved vertebra (p=0.046 OR 2.412 [95% CI 1.017–5.722]). Patients who suffered thoracic fracture had a significantly increased risk to suffer from PCE than those who suffered thoracolumbar fracture (p=0.001 OR 0.241 [95% CI 0.105–0.550]). And significantly increased PCE risk also was observed in thoracic fracture compared with lumbar fracture patients (p=0.028 OR 0.094 [95% CI 0.114–0.779]). The risk of PCE within 2 weeks after fracture was significantly higher than that after 2 weeks of fracture (p=0.000 OR 0.178 [95% CI 0.074–0.429]). Patients who underwent PVP surgery had a significantly increased PCE risk than those who underwent PKP surgery (p=0.001 OR 0.187 [95% CI 0.069–0.509]). Conclusion The real incidence of PCE is underestimated due to the lack of routine postoperative pulmonary imaging examination. The number of involved vertebrae, fracture location, operation timing, and operation methods are independent risk factors for PCE.

Background: Insufficient cement distribution (ICD) in the fractured area has been advocated to be responsible for unsatisfied pain relief after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCFs). However, little is known about risk factors for the occurrence of ICD. Objective: The present study aimed to identify independent risk factors of the emergence of ICD. Study Design: A retrospective cohort study. Setting: Department of spinal surgery, an affiliated hospital of a medical university. Methods: Patients who underwent PVP for single-level OVCF from January 2012 to September 2014 and met this study’s inclusion criteria were retrospectively reviewed. Associations of ICD with co-variates (age, gender, bone mass density with a T-score, amount of injected cement, cement leakage, fracture level, fracture age, fracture severity grade, and location of the fractured area) and the influence of ICD on pain relief were analyzed. Results: A total of 225 patients were included. ICD was found in 26 (11.6%) patients. Fractured area located in the superior portion of the index vertebra was significantly associated with occurrence of ICD. No further significant associations between the studied co-variates and emergence of ICD were seen in the adjusted analysis. In addition, patients with ICD had significantly higher immediate postoperative visual analog scale scores of back pain compared with those with sufficient cement distribution in the fractured area. Limitation: Location of the fractured area and cement distribution in the fractured area could not be evaluated quantitatively. Conclusions: The incidence of ICD is higher in patients with the fractured area located in the superior portion of the index vertebra and ICD might be responsible for unsatisfied pain relief after PVP for OVCFs.

Abstract Background Percutaneous vertebroplasty related postoperative secondary fractures risk factors were not consistent in patients with osteoporotic vertebral compression Fractures. The purpose was to identify the risk factors of the secondary fractures for osteoporotic vertebral compression fractures after percutaneous vertebroplasty.Methods Potential academic articles were identified from Cochrane Library, Medline, PubMed, Embase, ScienceDirect and other databases. The time range we retrieved from was that from the inception of electronic databases to August 2019. Gray studies were identified from the references of included literature reports. STATA version 11.0 (Stata Corporation, College Station, Texas, USA) was used to analyze the pooled data.Results Fourteen studies involving 1910 patients, 395 of whom had secondary fracture following the surgery were included in this meta-analysis. The results of meta-analysis showed the risk factors of the secondary fractures for osteoporotic vertebral compression fractures after percutaneous vertebroplasty was related to bone mineral density [WMD= -0.518, 95%CI(-0.784,-0.252), P=0.000], cement leakage [RR=0.596, 95%CI (0.444,0.798), P=0.001] and kyphosis after primary operation [WMD=4.510, 95%CI (3.061,6.004),P=0.000], but not to gender, age, body mass index (BMI), cement volume, thoracolumbar spine, and cement injection approaches.Conclusions BMD, cement leakage and kyphosis after primary operation are the risk factors closely correlative to the secondary fracture after percutaneous vertebroplasty. There has not been enough evidence to support the association between the secondary fracture and gender, age, body mass index, cement volume, thoracolumbar spine, and cement injection approach.
