Abstract

Indentation testing was performed on both the bursal and articular sides of the supraspinatus tendon to measure the compressive stiffness of the supraspinatus tendon and to determine whether regional difference exists in the bursal and articular side of the tendon. The overall initial stiffness on the bursal and articular sides of the tendon was significantly different. On the bursal side, the anterior third had a significantly higher stiffness than the other thirds on the average. On the articular side, initial stiffness at location 10 mm proximal to the greater tuberosity was significantly higher than the rest on average. The compressive stiffness of the supraspinatus tendon was found to be non-homogeneous throughout the structure.
