Abstract

This study aimed to identify risk factors for failure of conservative treatment of acute OVCFs. The results showed age, BMD, BMI, mFI, and IVC were high-risk factors for failure of conservative treatment of acute OVCFs.This study aimed to identify risk factors for failure of conservative treatment of acute osteoporotic vertebral compression fractures (OVCFs).This is a retrospective study of patients presenting with acute OVCFs who were initiated on conservative treatment for 3 weeks. Conservative treatment was considered to have failed if patients were not satisfied with pain relief or there were bed rest-related complications. These patients progressed to operation. Patients were divided into a conservative treatment failure group (group A) and a conservative treatment group (group B). X-ray, computed tomography and magnetic resonance imaging of two groups were performed on the first visit to our department due to OVCFs. Recorded data for comparison among groups included age, gender, fracture level, bone mineral density (BMD), body mass index (BMI), modified frailty index (mFI), whether the fractures were multiple (≥ 2 vertebral bodies was defined as multiple vertebral fractures) or combined with old fractures, and whether intervertebral cleft (IVC) was present.We collected data from 173 patients who underwent conservative treatment of acute OVCF in our hospital. Of these, 71 had conservative treatment failure, while 102 patients succeeded in long-term conservative treatment. After logistic regression analysis, age, BMD, BMI, mFI, and IVC were identified as high-risk factors for conservative treatment failure (P < 0.05). Age, BMD, BMI, and mFI were included in receiver operating characteristic curve analysis, the result showed that the cutoff value of age was 73.5 years old, of BMI was 23.65 kg/m2, of BMD was − 3.45, and mFI was 2.5.According to the results of this study, patients with high-risk factors should be actively observed during conservative treatment, especially for patients with all of the above risk factors, but further research would be required before considering early-stage treatment policy change.
