Computed tomography images of 35 shoulders of 34 patients with recurrent anterior dislocation and 13 shoulders of 13 healthy normal volunteers were used to determine the location of the Hill-Sachs lesion in reference to the location of the bare area using computed tomography.
We measured the location, and size of the Hill-Sachs lesion and the bare area, and described them on a clock face on the humeral head.
The Hill-Sachs lesion was observed in slices between 0-3 and 22-24 mm distal from the top of the humeral head. The bare area was located only in slices 19-21 mm and below.
From these data, we concluded that the Hill-Sachs lesion exists in the area between 0 and 24 mm from the top of the humeral head, and the inferior portion of the Hill-Sachs lesion overlaps the bare area if it extends beyond 19 mm from the top of the humeral head.
使用34例复发性前脱位患者的35个肩部以及13名健康正常志愿者的13个肩部的计算机断层扫描图像，通过计算机断层扫描确定希尔-萨克斯损伤相对于裸区的位置。
我们测量了希尔-萨克斯损伤和裸区的位置及大小，并在肱骨头的钟面上进行描述。
在距肱骨头顶部远端0 - 3毫米和22 - 24毫米之间的切片中观察到希尔-萨克斯损伤。裸区仅位于19 - 21毫米及以下的切片中。
根据这些数据，我们得出结论，希尔-萨克斯损伤存在于距肱骨头顶部0至24毫米的区域内，如果其从肱骨头顶部延伸超过19毫米，希尔-萨克斯损伤的下部与裸区重叠。
