Parameters of bone mass in the upper end of the femur--the thickness of the calcar femorale and the pattern of the trabeculae--were evaluated in preoperative films of patients who had undergone total hip replacement. Patients with primary coxarthrosis rarely showed signs of osteoporosis; on the contrary, one of the parameters of bone mass was above average in the coxarthrosis cases. However, there was no difference, in the preoperative films, between hips that later went on to show signs of mechanical loosening of the stem prosthesis and hips that remained intact in this respect.
在接受全髋关节置换术患者的术前X光片中，对股骨上端的骨量参数——股骨距厚度和小梁模式进行了评估。原发性髋关节病患者很少表现出骨质疏松的迹象；相反，在髋关节病病例中，其中一项骨量参数高于平均水平。然而，在术前X光片中，后来出现假体柄机械性松动迹象的髋关节与在这方面保持完好的髋关节之间没有差异。
