APPLICATION OF THE LANSS PAIN SCALE IN ASSESSING NEUROPATHIC PAIN IN PATIENTS WITH PRIMARY OSTEOPOROSIS WITH VERTEBRAL FRACTURES
Main Article Content
Abstract
Objective: To assess pain levels in patients with primary osteoporosis and vertebral fractures using the LANSS Pain Scale (The Leeds Assessment of Neuropathic Symptoms and Signs). Analyze the correlation between the study population's pain levels and clinical and paraclinical factors. Study population: The research was conducted on 80 patients diagnosed with primary osteoporosis according to the WHO 1994 criteria, experiencing spine pain with a VAS pain score ≥ 3 points, and having at least one vertebral fracture confirmed by MRI. The study was conducted at the Center for Rheumatology and Outpatient Clinic, Bach Mai Hospital, from August 2022 to December 2023. Research Methodology: Cross-sectional descriptive study. Results: Most patients had fractures of ≥ 2 vertebrae (58.8%). 83.8% of patients had lumbar vertebral fractures, and 61.3% had thoracic vertebral fractures. Spinal MRI revealed that 87.5% of patients had new vertebrae fractures. The prevalence of neuropathic pain in patients with primary osteoporosis with vertebral fractures according to the LANSS Pain Scale was 37.5%. The risk of neuropathic pain in the age group >70 was 3.62 times higher than the age group ≤70, and those with a VAS score ≥ 7 had a 3.62 times higher risk than those with a VAS score < 7. The risk of neuropathic pain in the group with a fracture of ≥ 2 vertebrae was 4.7 times higher than in the group with a fracture of 1 vertebra. Regarding spinal MRI, the group with posterior vertebral wall protrusion had a 5.75 times higher risk of neuropathic pain than the group without, and the group with spinal canal stenosis had a 6.71 times higher risk than the group without. Conclusion: The risk of spine pain due to neuropathic causes increases in the age group >70, those with a VAS score >7, compression of ≥ 2 vertebrae, MRI showing posterior vertebral wall protrusion, and spinal canal stenosis. These differences are statistically significant with p < 0.05
