In most previous reports of OA, bone mineral density (BMD) changes in the subtrochanteric region have not been clarified, whilst BMD of the femoral neck and trochanteric region has been well investigated. In our current study, we investigated the BMD ratio compared to the contralateral side in the whole proximal femurs of hip OA patients. We aimed to clarify the morphologic factor that may influence these BMD ratios. We performed dual energy X-ray absorptiometry (DEXA) analysis of 69 hip joints from unilateral progressed OA cases. The minimum joint space, center edge angle, Sharp angle, acetabular head index, neck-shaft angle, and leg length discrepancy were also measured as radiographic factors. The correlation between BMD ratio and radiographic morphologic factors was then evaluated by logistic regression. The BMD ratio was higher in the femoral neck than in the distal region. In terms of radiographic factors, the neck-shaft angle was revealed to influence the decreased BMD ratio in the distal subtrochanteric part, whilst the leg length discrepancy and Sharp angle showed a relationship with the increased BMD ratio in the proximal neck region. The discrepancy in the BMD ratio between the femoral neck and the distal subtrochanteric region in the proximal femur is influenced by several morphologic factors.
