Abstract
OBJECTIVES: Osteoporotic vertebral fractures are responsible for acute pain and disability that may persist for more than 2 months. We wanted to identify predicting factors for mid-term outcome after vertebroplasty. METHODS: We included consecutive patients who underwent vertebroplasty for fragility fractures with persistent and intense pain between January 2014-June 2016. Outcome was assessed by an independent clinician after 1 month using a standardized questionnaire. Patients were classified as having either a favorable or a poor outcome. Presence of an intravertebral cleft and bone oedema mean signal intensity was assessed by an independent radiologist blinded to the clinical data. Pre-intervention clinical or radiological factors were analysed as predictors for outcome. RESULTS: In the 78 included patients (females 71%, age 75 ± 8.3 years), 61.5% had a favourable outcome. When vertebroplasty was performed within 2 months after fracture, the outcome was favourable in 19 patients (39.6%) and poor in five (16.7%; estimate for favourable outcome: OR = 4.1, 95% CI 1.2-13.8, p = 0.021). Absence of intravertebral cleft on pre-intervention imaging was also a predictor of favourable outcome (OR = 3.7, 95% CI 1.2-11.8, p = 0.024). On pre-intervention MRI, vertebral body oedema intensity signal did not influence the outcome. CONCLUSIONS: In patients with persistent and intense pain after an osteoporotic vertebral fracture, early intervention and absence of intravertebral cleft were predictors of favourable outcome at 1 month after vertebroplasty. KEY POINTS: • Performing vertebroplasty within 2 months following a fragility fracture increases success rate. • Presence of an intravertebral cleft at baseline is a predictor of poor mid-term outcome. • A pre-intervention MRI should be performed to ascertain the indication of vertebroplasty.
