Mechanism of Mersilene suture alleviated hook pressure of hook plate. Hook of hook plate will provide strongly vertical stability by attached to inferior cortex of acromion. However, in hook plate fixation without Mersilene suture augmentation, high pressure of hook tip will cause subacromial osteolysis and possible loss of reduction of AC joint (Red arrow). With Mersilene suture augmentation, pressure of hook tip will be alleviated and decreased possible of subacromial osteolysis and provide vertical stability after remove hook plate (Blue arrow)
