Abstract
- <bold>Background: </bold>To measure volumetric bone mineral density (vBMD) with quantitative computed tomography (QCT) in the proximal femur of ankylosing spondylitis (AS) patients with hip involvement and analyze their correlations with radiographic and clinical parameters.<bold>Methods: </bold>Sixty-five AS inpatients were enrolled in this study. The bone mineral density was measured by QCT and dual-energy x-ray absorptiometry (DXA), respectively. The morphological parameters of the proximal femur were measured on digital anteroposterior (AP) radiographs of the pelvis. The correlations between them were analyzed by SPSS software.<bold>Results: </bold>The average trabecular vBMD measured at the femoral neck was 136.38 ± 25.58 mg/cm3. According to the BASRI-Hip score, group A consisted of 39 hips (0-2 score) and group B consisted of 26 hips (3-4 score). There were significant differences regarding trabecular CTXA equivalent T-score between group A and B at the femoral neck (p = 0.004); intertrochanteric region (p < 0.001) and greater trochanter (p = 0.001). The trabecular CTXA equivalent T-score at femoral neck had a negative correlation with disease duration (r = - 0.311, p = 0.012) and with CBR (r = - 0.319, p = 0.010).<bold>Conclusions: </bold>The low trabecular bone density at the site of the hip was associated with the duration of disease progression and degree of hip involvement. Meanwhile, it had a correlation with hip function status although we failed to confirm a significant relationship between hip vBMD and disease activity. [ABSTRACT FROM AUTHOR]
