A new method of measuring the distal torsion of the femoral bone is introduced. The term "torsion" is defined, and the etiology of femoral torsion is scrutinized. The sources of error are discussed after a description of the process of measurement and of the calculation of the angle of torsion. The aim and value of this method are, firstly, to supply evidence for the existence of a prearthrosis factor of the patellofemoral joint, and, secondly, to be of practical importance for the consequences of surgery. These consequences will be discussed elsewhere.
介绍了一种测量股骨远端扭转的新方法。定义了“扭转”一词，并仔细研究了股骨扭转的病因。在描述测量过程和扭转角度计算之后，讨论了误差来源。该方法的目的和价值，首先是为髌股关节关节病前期因素的存在提供证据，其次是对手术后果具有实际重要性。这些后果将在其他地方讨论。
