Ruptured muscles in the arm can be more subtle
Proximal biceps rupture:
Rupture of the long head of the biceps at the shoulder makes the arm muscle look bigger. There is no loss of function because the muscle has another attachment at the shoulder. Surgery is not needed. Proximal biceps rupture is part of rotator cuff degeneration. |
Distal biceps rupture:
