Diagnostic difficulties in the radiological assessment of subscapularis tears

Abstract Background Radiological evaluation of rotator cuff tears are sensitive and specific. Accuracy may be low in diagnosing subscapularis tears. Materials and methods We retrospectively reviewed shoulder arthroscopies performed by two surgeons over 45 months. We reviewed patients who had subscap...

Description
Summary:Abstract Background Radiological evaluation of rotator cuff tears are sensitive and specific. Accuracy may be low in diagnosing subscapularis tears. Materials and methods We retrospectively reviewed shoulder arthroscopies performed by two surgeons over 45 months. We reviewed patients who had subscapularis repairs and their preoperative imaging. Result 286 cases had imaging (193 MRIs, 93 USS) with 77 subscapularis repairs. MRI suggested 31 tears, arthroscopy confirmed 16 (30% sensitivity, 89% specificity). USS suggested 6 tears, arthroscopy confirmed 4 (13% Sensitivity, 97% specificity). Discussion Results demonstrated low accuracy for preoperative radiological subscapularis tear assessment. This has logistical, diagnostic and implications on treatment.
