摘要：Operation is one of the choices for the treatment of hip fractures in elders. However, how to assess the bone mineral density ( BMD ) and bone structure pre-operation are challenging. Dual-energy x-rays absorptiometry ( DXA ) is widely used for BMD measurement of the hip, but limited in elder hip fractures due to the pain leading to the difficulty of positioning. Furthermore, DXA is unable to measure the BMD of the femoral head. In this commentary, we introduced "Beijing Jishuitan hospital sailing project" experience which is to combine the routine clinical hip CT scan with the quantitative computed tomography ( QCT ) of the hip for elder hip fractures. With a single hip CT scan, the details of the hip fracture can be shown, meanwhile the CT data are used for QCT analysis of the the hip, in which the DXA-equivalent BMD is measured. BMD of the femoral head, neck and trochanteric area can be measured as well. All measurements are very useful for the pre-operation planning. QCT is utilizing the clinical CT scan with QCT calibration phantom and software, further post-processing of CT data, with no additional radiation. We completed more than 3000 cases of QCT and it is proved to be very successful, so we recommend to use QCT for hip fractures.
