Diagnosis of subscapularis tendon rupture is difficult because it can frequently be reduced and specific symptoms are few. Recently, there have been many reports on the effectiveness of MRI to diagnose rupture of the subscapularis tendon. We found MRI to be very effective for confirming rupture as reported, although we only experienced two examples. We report on the arthrography, MRI, and surgical findings in these cases. Amalgamating RSD immediately after the operation improve the symptoms of one case limitation in the ROM in the other case did not improve although the pain disappeared in both cases after operating.
We also report on our method of rebuilding the damage to the rotater interval which amalgamates with rupture of the subscapularis tendon. We believe that restoration of the rotater cuff interval is very important for successful treatment of this disease.
