Correlation between Degree of Radiologic Signs of Osteoarthritis and Functional Status in Patients with Chronic Mechanical Low Back Pain

ABSTRACT

Background: Osteoarthritis is the most intervening factors in producing mechanical low back pain (LBP). We aimed to evaluate the correlation between radiologic signs of osteoarthritis and functional status in patients with chronic mechanical LBP. Methods: Severity of osteoarthritis and disability were evaluated with Kellgren and Lawrence Grading Scale (K&L) by simple lumbar X-ray and Oswestry Disability Questionnaire (ODQ) respectively. Results: Although there was no significant correlation between ODQ and K&L score in general, the correlation was seen in female group (P = 0.024, r = 0.207). Conclusions: Mechanical LBP provides more disability in females suffering from more advanced osteoarthritis.
