Özet
Background/aim: The purpose of this study is to investigate whether the etiological factors accepted as causes of idiopathic subscapularis
tears are true or not when the comparison is made with the opposite side healthy shoulder of the patients who underwent arthroscopic
repair for an isolated subscapularis tear.
Materials and methods: Sixteen patients who underwent shoulder arthroscopy between February 2016 and January 2018 and
were diagnosed with isolated subscapularis tear were evaluated. The coracohumeral distance (CHDax), coracoid overlap (CO), and
tuberculum minus cysts (TMC) were evaluated on the axial images of the MRI studies while the acromiohumeral distance (AHDsag),
CHDsag, and subscapularis tendon slip number (STSN) on the sagittal oblique images and the AHDcor and SLAP lesion on the coronal
oblique images. Degeneration of the coracoacromial ligament was evaluated during arthroscopy.
Results: The mean CHDsag (11.26–10.08), CHDax (10.63–9.98), CO (14.2–15.43), AHDsag (8–7.66), and AHDcor (7.65–7.68)
measurements (operated side-healthy side, respectively) were statistically similar (p > 0.05). No statistically significant difference was
found between TMC and STSN in healthy and operated shoulders (p > 0.05). There was mild coracoacromial ligament fraying in 4
(25%) and obvious coracoacromial ligament fraying in 8 (50%) which indicated subacromial impingement in 75% of the patients.
Conclusion: The parameters of the coracoid process did not reveal any significant difference between the operated (for an isolated
subscapularis tear) and opposite-side healthy shoulders of the patients. However, coracoacromial ligament degeneration was present in
75% of the patients
