Three-dimensional imaging of hip joint preparations was carried out by means of computed tomography (CT). On the assumption that the head of the femur and acetabulum are incongruent, a special experimental design was used to quantify the extent and direction of the gliding movement of the head and socket. A series of CT images in the supine and prone positions was made from hip preparations, and the cartilage was visualized by injecting a contrast medium. In all the preparations dorsal movement was noted in the supine position, and ventral movement in the prone position. Cryomicrotome slices of the hip preparations were used to verify the results of our CT scans and the measurements correlated with the anatomical examinations. Thus, there is a certain amount of play in the hip joint-it is not an ideal ball-and-socket joint. This knowledge is important for the planing and success of hip adjustment surgery.
通过计算机断层扫描（CT）对髋关节标本进行三维成像。假设股骨头部和髋臼不匹配，采用一种特殊的实验设计来量化股骨头与髋臼窝滑动运动的程度和方向。从髋关节标本获取仰卧位和俯卧位的一系列CT图像，并通过注射造影剂使软骨可视化。在所有标本中，仰卧位时观察到背侧运动，俯卧位时观察到腹侧运动。髋关节标本的冷冻切片用于验证CT扫描结果，测量结果与解剖学检查相关。因此，髋关节存在一定程度的间隙——它不是一个理想的球窝关节。这一认识对于髋关节调整手术的规划和成功至关重要。
