Characteristics of neuropathic pain assessed by the DN4 questionnaire in patients with primary osteoporosis
Main Article Content
Abstract
A cross-sectional descriptive study was conducted on 86 patients diagnosed with primary osteoporosis, presenting with spinal pain and a VAS score ≥ 3 at Bach Mai Hospital from July 2025 to April 2026 to describe neuropathic pain; the DN4 questionnaire was utilized to gather data. The study population exhibited a mean age of 70.4 ± 10 years old, with a predominant female distribution of 87.2%. The prevalence of neuropathic pain according to the DN4 questionnaire was 36.0%. Multivariate logistic regression analysis revealed that a history of prior fracture (AOR = 11.83; 95% CI: 2.91 – 48.07; p < 0.001) and radiographic vertebral compression fracture (AOR = 55.88; 95% CI: 2.45 – 86.06; p = 0.012) were independently associated with the presence of neuropathic pain. In conclusion, neuropathic pain accounts for a significant proportion of primary osteoporosis patients with spinal pain of at least moderate intensity. A history of fracture and radiographic vertebral compression fracture are independent factors associated with neuropathic pain assessed by the DN4 questionnaire.
