The aim of this study was to clarify the relationship between superior migration of the humeral head and torn tendon on massive rotator cuff tear. We studied 23 shoulders in 17 patients of massive rotator cuff tear seen from April 2004 to March 2007 in our hospital. There were 15 men and 2 women, their mean age was 70.5 years old (range, 56-81 years old), right-side 16 shoulders and left-side 7 shoulders. We evaluated the superior migration of the humeral head by X-rays on the supine and standing position, and torn tendon size by MRI. We evaluated whether rupture of the long head of the biceps tendon (LHB) led to the superior migration of the humeral head. On X-rays, superior migration of the humeral head were recognized in 7 shoulders in both the supine and standing positions, 13 shoulders were so only in the supine position. Three shoulders were recognized neither in the supine nor standing position. On MRI, all 7 shoulders showed superior migration in the standing position recognized complete tears in supraspinatus, infraspinatus and subscapularis tendon, and 19 of 20 shoulders in the supine position recognized rupture of the LHB tendon. In massive rotator cuff tear, the superior migration in the supine position will take place if the LHB tendon is ruptured, and thus further the superior migration in the standing position will take place if the infraspinatus and subscapularis are torn completely, because the depressor for the humeral head is lost.
