The purpose of this study was to measure the new footprints of the supraspinatus and infraspinatus we previously reported on. 20 shoulders of 12 cadavers were used in this study. We measured the maximum length and width of the footprint of the supraspinatus and infraspinatus. The distances from the three landmarks; the anterior margin of the greater tuberosity, the border between the highest and middle impressions and the anterior edge of the sulcus, to the border between the supraspinatus and infraspinatus were measured. The footprint of the supraspinatus had an average maximum length of 12.6 mm and width of 6.9 mm. That of the infraspinatus had an average maximum length of 32.7 mm and width of 10.2 mm. On the lateral margin of the greater tuberosity, the border between the supraspinatus and infraspinatus was 1.3 mm posterior to the anterior margin of the greater tuberosity and 6.9 mm anterior to the border between the highest and middle impression. On the medial margin, the border between the supraspinatus and infraspinatus was 12.6 mm posterior to the anterior margin of the greater tuberosity, 2.0 mm anterior to the border between the highest and middle impressions and 13.8 mm anterior to the anterior edge of the sulcus. These numeric data, which supplement our previous reports about humeral insertion of the supraspinatus and infraspinatus, could help the surgeons in the diagnosis and repair of rotator cuff tears.
