A clinical tool to identify older women with back pain at high risk of osteoporotic vertebral fractures (Vfrac): a population-based cohort study with exploratory economic evaluation.

ABSTRACT:

Background

osteoporotic vertebral fractures (OVFs) identify people at high risk of future fractures, but despite this, less than a third come to clinical attention. The objective of this study was to develop a clinical tool to aid health care professionals decide which older women with back pain should have a spinal radiograph.

Methods

a population-based cohort of 1,635 women aged 65+ years with self-reported back pain in the previous 4 months were recruited from primary care. Exposure data were collected through self-completion questionnaires and physical examination, including descriptions of back pain and traditional risk factors for osteoporosis. Outcome was the presence/absence of OVFs on spinal radiographs. Logistic regression models identified independent predictors of OVFs, with the area under the (receiver operating) curve calculated for the final model, and a cut-point was identified.

Results

mean age was 73.9 years and 209 (12.8%) had OVFs. The final Vfrac model comprised 15 predictors of OVF, with an AUC of 0.802 (95% CI: 0.764-0.840). Sensitivity was 72.4% and specificity was 72.9%. Vfrac identified 93% of those with more than one OVF and two-thirds of those with one OVF. Performance was enhanced by inclusion of self-reported back pain descriptors, removal of which reduced AUC to 0.742 (95% CI: 0.696-0.788) and sensitivity to 66.5%. Health economic modelling to support a future trial was favourable.

Conclusions

the Vfrac clinical tool appears to be valid and is improved by the addition of self-reported back pain symptoms. The tool now requires testing to establish real-world clinical and cost-effectiveness.

Project description:Study designA retrospective analysis.PurposeTo investigate the occurrence of central sensitization (CS) in patients with osteoporotic vertebral compression fractures (OVCFs) and identify the association between CS and residual back pain (RBP).Overview of literatureRBP is a vexing complication that affects 6.3%-17.0% of patients with OVCFs who underwent percutaneous vertebroplasty (PVP). Given the negative effect of RBP on patients' psychological and physiological statuses, efforts to preoperatively select patients who are at risk for RBP development have a high priority to offer additional treatment and minimize this complication.MethodsPreoperatively, all 160 patients with OVCFs underwent pressure-pain threshold (PPT), temporal summation (TS), conditioned pain modulation (CPM), and imaging assessments. Pain intensity and pain-related disability were evaluated before and after PVP.ResultsPreoperatively, patients with OVCFs had lower PPTs in both local pain and pain-free areas and lower CPM and higher TS in pain-free areas than healthy participants (p<0.05). Unlike patients with acute fractures, patients with subacute/chronic OVCFs showed higher TS with or without lower CPM in the pain-free area compared with healthy participants (p<0.05). Postoperatively, RBP occurred in 17 of 160 patients (10.6%). All preoperative covariates with significant differences between the RBP and non-RBP groups were subjected to multivariate logistic regression, showing that intravertebral vacuum cleft, posterior fascia edema, numeric rating pain scale scores for low back pain at rest, and TS were independently associated with RBP (p<0.05).ConclusionsAugmented central pain processing may occur in patients with OVCFs, even in the subacute stage, and this preexisting CS may be associated with RBP. Preoperative assessment of TS in pain-free areas may provide additional information for identifying patients who may be at risk of RBP development, which may be beneficial for preventing this complication.

Project description:BackgroundMost patients with osteoporotic vertebral compression fracture (OVCF) obtain pain relief after vertebral augmentation, but some will experience residual back pain (RBP) after surgery. Although several risk factors of RBP have been reported, it is still difficult to estimate the risk of RBP preoperatively. Radiomics is helpful for disease diagnosis and outcome prediction by establishing complementary relationships between human-recognizable and computer-extracted features. However, musculoskeletal radiomics investigations are less frequently reported.ObjectiveThis study aims to establish a radiomics score (rad-score) based nomogram for the preoperative prediction of RBP in OVCF patients.MethodsThe training cohort of 731 OVCF patients was used for nomogram development, and the validation cohort was utilized for performance test. RBP was determined as the score of visual analogue scale ≥ 4 at both 3 and 30 days following surgery. After normalization, the RBP-related radiomics features were selected to create rad-scores. These rad-scores, along with the RBP predictors initially identified by univariate analyses, were included in the multivariate analysis to establish a nomogram for the assessment of the RBP risk in OVCF patients preoperatively.ResultsA total of 81 patients (11.2%) developed RBP postoperatively. We finally selected 8 radiomics features from 1316 features extracted from each segmented image to determine the rad-score. Multivariate analysis revealed that the rad-score plus bone mineral density, intravertebral cleft, and thoracolumbar fascia injury were independent factors of RBP. Our nomograms based on these factors demonstrated good discrimination, calibration, and clinical utility in both training and validation cohorts. Furthermore, it achieved better performance than the rad-score itself, as well as the nomogram only incorporating regular features.ConclusionWe developed and validated a nomogram incorporating the rad-score and regular features for preoperative prediction of the RBP risk in OVCF patients, which contributed to improved surgical outcomes and patient satisfaction.

Project description:Vertebral fractures are frequent clinical consequences of osteoporosis. Considering the demographic change in Europe, the number of vertebral fractures will quite likely increase during the next decades. Apart from pharmaceutic agents and physiotherapy, spinal orthoses are established elements of conservative therapy for vertebral (body) fractures. Recent studies on acute vertebral fractures reported positive effects on back pain, kyphosis and functional disabilities, but the efficacy of active strengthening spinal orthoses in vertebral fractures ≥6 months remains to be established. Eighty hyperkyphotic, community-dwelling women ≥65 years with chronic back pain and vertebral fractures occurred ≥3 months ago were randomly allocated to a group which wore the "Spinomed active" orthoses 2 × 2-3 h/d for 16 weeks (SOG: n = 40) or an untreated control group (CG: n = 40). Study outcomes were back pain intensity, kyphosis angle, trunk strength, back pain induced- and general function and disability, functional ability (chair-rise test) and respiratory function. We applied an intention-to-treat analysis; data were consistently adjusted for baseline values applying an ANCOVA. Observing a compliance of 82 ± 14% with the wearing protocol, we determined large and significant favorable effects for back pain (p = .008), back pain-induced physical disability (p < .001) and kyphosis angle (p < .001). We also demonstrated positive effects on trunk strength (p = .049), functional ability (p = .062) and general function and disability (p = .057), although not all of the parameters reach significance. No relevant changes were observed for respiratory function. After a few further individual adjustments of the orthosis (n = 2), no adverse effects were reported. In summary, the present study provided evidence for the efficacy of an active strengthening spinal orthosis ("Spinomed active") in people with vertebral fractures ≥6 months. Based on our results, we recommend expanding the application of the "Spinomed active" orthosis, which was previously validated for acute vertebral fractures, also to older hyperkyphotic women with osteoporotic vertebral fractures ≥3 months.

Project description:IntroductionOsteoporosis-associated vertebral fractures represent an increasing clinical and public health problem, one with important socioeconomic effects within western countries. The purpose of this study was to analyse demographic, medical, gender and socioeconomic aspects of osteoporotic vertebral fractures of the thoracic or lumbar spine over a period of at least 10-years.Material and methodsIncluded for analysis were 694 patients who had suffered a vertebral fracture due to primary or secondary osteoporosis, and who were treated at our Level-I trauma center between 2000 and 2013. Collected data included demographic, medical and socioeconomic aspects.ResultsClinical results revealed that 669 patients (96%) were treated conservatively. The remaining 25 patients (4%) underwent surgical therapy: 4 were treated with vertebroplasty, 15 with kyphoplasty and 6 patients with posterior stabilization. The mean age was 75.6 years (range: 50-98), with the vast majority of patients being female (n = 515). A statistically significant demographic difference (i.e., increase) in fractures was observed between the age groups 60-69 and 70-79 (p = 0.041). Concerning socioeconomic aspects, statistical analysis showed that the number of sick leaves and the need for professional domestic help was higher in female patients. Concerning treatment costs, statistical analysis did not reveal any significant differences between female and male patients.ConclusionSignificant gender differences-to the detriment of the female population-could be demonstrated within this study. A regrettably low rate of adequate treatment after diagnosis of osteoporosis and its associated fractures-specifically relating to primary and secondary prevention-could also be identified. To prospectively avoid complications and consequential cost increases, more awareness of the necessity for prevention, early diagnosis and adequate treatment of osteoporosis and its related fractures should be considered.
