dc.description.abstractSubscapularis tendon tears are a well-established cause of shoulder pain. The objective of the current study was to evaluate the associated shoulder pathology in patients with full-thickness subscapularis tendon tears using magnetic resonance imaging. Forty-seven magnetic resonance imaging studies taken between 2008 and 2009 with a diagnosis of full-thickness subscapularis tendon tears were reviewed. The size of the subscapularis tendon tear, amount of muscle volume loss, Goutallier grade, biceps tendon pathology, coracohumeral distance, and associated rotator cuff tears were recorded. Statistical analysis was performed. Patients 55 years and older vs those 54 years and younger had an average subscapularis tear size of 35 vs 19 mm, an average Goutallier grade of 2.7 vs 0.8, and a total muscle volume loss of 25% vs 5%, respectively. Patients with a dislocated vs normal biceps tendons had an average subscapularis tear size of 37 vs 23 mm, an average Goutallier grade of 3 vs 0.9, and a total muscle volume loss of 28% vs 7%, respectively. Patients with vs without concomitant rotator cuff tears had an average subscapularis tear size of 32 vs 17 mm, an average Goutallier grade of 2.3 vs 0.6, and a total muscle volume loss of 21% vs 3%, respectively. Overall average coracohumeral distance measured in the axial plane was 10.8+/-4.6 mm. Average coracaohumeral distance was 14.8 vs 8.1 mm in patients with a Goutallier grade of 0 vs 3 or 4, resepectively, and 13.6 vs 8.5 mm in patients with no rotator cuff tear vs those with a supra- and infraspinatus tear, respectively.Increased age, dislocated biceps tendons, and concomitant rotator cuff tears in patients with full-thickness subscapularis tendon tears are associated with larger subscapularis tendon tear size, higher Goutallier grades, and increased subscapularis muscle volume loss. Decreased coracohumeral distance is associated with a higher Goutallier grade and rotator cuff tears.
