Risk factors and score for recollapse of the augmented vertebrae after percutaneous vertebroplasty in osteoporotic vertebral compression fractures

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.

Abstract Background Osteoporotic vertebral compression fracture (OVCF) is one of the most common fragile fractures, and percutaneous vertebroplasty provides considerable long-term benefits. At the same time, there are many reports of postoperative complications, among which fracture after percutaneous vertebroplasty is one of the complications after vertebroplasty (PVP). Although there are many reports on the risk factors of secondary fracture after PVP at home and abroad, there is no systematic analysis on the related factors of secondary fracture after PVP. Methods The databases, such as CNKI, Wan Fang Database and PubMed, were searched for documents on secondary fractures after percutaneous vertebroplasty published at home and abroad from January 2011 to March 2021. After strictly evaluating the quality of the included studies and extracting data, a meta-analysis was conducted by using Revman 5.3 software. Results A total of 9 articles were included, involving a total of 1882 patients, 340 of them diagnosed as secondary fractures after percutaneous vertebroplasty. Conclusion The additional history of fracture, age, bone mineral density (BMD), bone cement leakage, intravertebral fracture clefts and Cobb Angle might be risk factors related to secondary fractures after percutaneous vertebroplasty for osteoporotic vertebral compression fractures. The height of vertebral anterior and body mass index (BMI) were not correlated.
