AbstractBackground: The neuropathic characteristics of pain occurring after an osteoporosis (OP)-related fracture are often under-recognized. The aim of this pilot study is to identify, in patients suffering from pain localized on the site of a previous osteoporotic fracture, the presence of neuropathic characteristics, their medical management, and their impact on quality of life. Methods: This pilot cross-sectional study on consecutive patients in University Hospital, Rheumatology Department, Clermont-Ferrand, France, was approved by the Ethics Committee (IRB number 2023-CF34). Pain was evaluated with the Numeric Pain Rating Scale (NPRS), Neuropathic Component of Chronic pain (NCCP) was screened with the DN4 questionnaire, and sleep was assessed with the Pittsburg questionnaire. Depression, anxiety, quality of life, and concomitant treatment were also evaluated. Results were expressed using effect sizes (ESs) and 95% confidence intervals. Results: Fifty new patients with a history of at least one fully documented fragility vertebral fracture (VF) or nonvertebral fracture (NVF) due to osteoporosis, in the last 2 years minus the previous 6 months, were included. Findings show that 21% patients with VF and 28% patients with NVF reported NCCP (DN ≥ 4). NCCP patients had more intense pain (NPRS = 5.1 ± 2.9 vs. 2.9 ± 2.7, ES = 0.82 [0.18; 1.44], p=0.019) and impaired sleep compared to patients without NCCP (ES = 0.71 [0.08; 1.33], p=0.043). A remarkable point was that patients had no specific oral or topical treatment for NCCP and were only taking on demand paracetamol and nonsteroidal anti-inflammatory drugs. Conclusions: Future research should focus on the neuropathic characteristics of pain patients with OP, in order to better manage OP-related pain.Copyright © 2024 Marie-Eva Pickering et al.
