Abstract
Introduction
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.
Method
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.
Results
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.
Conclusion
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.
