Comparison of PA spine, lateral spine, and femoral BMD measurements to determine bone loss in ankylosing spondylitis

摘要: To evaluate bone loss in the early- and late-stage ankylosing spondylitis (AS) patients using posteroanterior (PA) lateral lumbar femoral mineral density (BMD) measurement methods. Eighty-six AS 50 control subjects were enrolled. PA spine, femur BMD values of controls measured. The presence any syndesmophytes or compression fractures was determined. Patients divided as early (<10 years) late stage (≥10 according to onset inflammatory pain. Mean spinal similar (p = 0.460). Femoral spine significantly lower 0.012 p 0.001). When comparing groups, mean found be group 0.005), while (although statistically not significant) group. At least one fracture present 28 % patients. Although significant, higher those with fractures. 0.034 0.004). Lateral Bone is increased compared subjects. at reflects risk better than measurements.
