Evaluation Of Bone Mineral Density In Patients With Chronic Low Back Pain

Study Design: This was designed as a retrospective study.Purpose: We investigated the relationship between bone mineral density (BMD) and chronic lower back pain (LBP).Overview of Literature: In spite of a large number of epidemiological surveys on the prevalence of LBP and BMD measurements completed separately in the general population, the relationship between the two has not been well documented.Methods: The study included 171 patients with chronic LBP who underwent the BMD study. The control group was selected from our database regarding BMD without LBP.Results: A total of 678 subjects, aged 18 to 100 years (mean, 49.9 +/- 12.9 years) were included in the study, 25% (n=171) of the subjects had LBP. Compared to those patients without LBP, patients exhibiting LBP had statistically significant lower mean weight, hip and spine BMD and T-score. Lower BMD and T-scores were significant regardless of the age group, gender, menopausal status, and obesity classification.Conclusions: Chronic LBP has a negative correlation with hip and spine bone mineral density.
