The high frequency of superior labrum, biceps tendon, and superior rotator cuff pathologies in patients with subscapularis tears: A cohort study.

Abstract

The purpose of this study was to assess the frequency of superior labrum anterior posterior (SLAP) lesions, long head of biceps tendon (LHBT) pathologies, and superior rotator cuff tears accompanying subscapularis tears. We hypothesised that LHBT lesions, superior rotator cuff tears, and especially SLAP lesions were very frequent with subscapularis tears. The digital files of patients who underwent shoulder arthroscopy were reviewed retrospectively. One hundred and eleven patients with subscapularis tears evident on surgery videos were examined. Superior labrum, LHBT, and superior rotator cuff lesions were investigated by the authors of this study. The statistical analyses were made with SPSS statistics software, and significance was set at P<0.05 value. There were 111 patients with both subscapularis tears and surgery videos. The mean age was 58.09±10.21, and 63.1% of the patients were female. 98.2% of the 111 patients had a SLAP lesion. 7.2% of those were SLAP I and 91% were SLAP II lesions while 1.8% were healthy. The 75.7% of the patients had a LHBT pathology, and 83.8% had superior cuff tear. Subscapularis tears were almost always accompanied by SLAP lesions. On the other hand, biceps tendon pathologies and superior rotator cuff tears were also very frequent with subscapularis tears. Prognostic study, Level IV (retrospective cohort study).
