The goal of the project was to quantify measurements of the insertion of the rotator cuff muscles and superior capsule in three-dimensions.
Cadaveric specimens were dissected down to the level of the rotator cuff/capsular complex. Each of the four rotator cuff muscles (subscapularis, supraspinatus, infraspinatus, and teres minor) were removed individually from the humerus and marked, followed by the superior capsule on the humerus and scapula. A laser scanning system was to make three-dimensional models of each of the specimen. The perimeter of each insertion was also digitized with a probe and incorporated into the models. The surface area and centroid of each insertion were calculated and measurements along the surface of the longest dimension and perpendicular dimension through the centroid as well the distance from the centroid to the apex of the bicipital groove were made.
The infraspinatus had the largest insertion area at 277.7 mm2, followed by the subscapularis (262.8 mm2), the teres minor (251.0 mm2), and the supraspinatus had the smaller insertion area (133.7 mm2).
The subscapularis, infraspinatus, and teres minor have larger insertions areas on the humerus when compared to the supraspinatus.
