title: Magnetic resonance imaging analysis of the subscapularis muscle after arthroscopic and open shoulder stabilization.
abstract: To evaluate the subscapularis muscle (SSC) after arthroscopic and open shoulder stabilization, three groups [after arthroscopic (A), after open shoulder stabilization (B), healthy volunteers (0)] underwent magnetic resonance imaging. Magnetic resonance parameters were compared with clinical SSC tests and shoulder scores. From Group 0 to B, the diameters of the SSC decreased, and the fatty degeneration of the upper SSC increased (P<.05) from Group 0 and A to B according to clinical findings. The functional shoulder scores did not differ (P>.05). Magnetic resonance analysis provides reasons of postoperative SSC dysfunction.
