Relationship between Disability and Radiographic Findings of Lumbar Disc Degeneration in Sample of Iraqi Patients with Mechanical Low Backache
Background: Disability related to chronic low back pain is a complex and multidimensional phenomenon all over the world. Aims of study: To evaluate the associations of x-ray features of lumbar disk degeneration with severity of disability among patients with mechanical low back pain. Patients and Methods: A cross-sectional study was conducted on a total of 300 patients with chronic mechanical low back pain. Severity of disability was measured using Modified Oswestry Disability Index and intensity of backache was assessed using numeric rating scale (0 -10). X-ray features of lumbar disc degeneration according to Lane classification and spondylolisthesis were assessed in lateral recumbent lumbar x-rays. Results: the mean age of our sample was 52.45 ± 7.87. The findings of disc space narrowing were mild in 65.7%, moderate in 28.7%, and severe in 5.6%, where the presence of osteophytes were small in 76.9%, moderate in 20.5%, and large in 2.6%. Regarding disability, two third of cases were focused on minimal disability followed by moderate, severe, and crippled as (26%), (6%) and (2%) respectively. There was highly significant association between women and pain radiation to legs (p-value=0.004). Obesity and overweight had meaningless effects on all markers. Conclusions: The severity of disability was significantly more in women, high intensity of lower back pain, presence of pain radiating to legs, moderate/severe disc space narrowing on x-ray and disc degenerative disease score on x-ray, while age, presence of osteophytes and spondylolisthesis, body mass index and pain duration were not associated with severity of disability.
