“…In previous reports, changes at the lesser tuberosity such as lesser tuberosity cysts and cortical irregularities were associated with subscapularis tendon tears (1,(13)(14)(15). However, the data acquired in this study failed to show that the lesser tuberosity changes, including cyst formations and bone marrow edema, would be reliable MRI features indicating the presence of a subscapularis tendon tear.…”

Background The diagnostic accuracy of magnetic resonance imaging (MRI) is low for detecting a subscapularis tendon tear. Purpose To identify MRI findings that may predict the presence of a clinically significant subscapularis tendon tear requiring surgical repair. Material and Methods We reviewed shoulder MR images of patients who had undergone arthroscopic rotator cuff repair at our institution between June 2018 and May 2019. Patients were divided into two groups: the study group (n = 51), with an intermediate- to high-grade partial thickness tear of the subscapularis tendon suspected on preoperative MRI and intermediate or higher grade of the tendon tear proven on arthroscopy; and the control group (n = 18), with an intermediate- to high-grade partial thickness tear of the subscapularis tendon suspected on preoperative MRI but no tear or low-grade partial thickness tear of the tendon shown on arthroscopy. Preoperative MR images were retrospectively evaluated by two readers for the size of the subscapularis tendon tear, bone reactions at the lesser tuberosity, and long head of the biceps tendon (LHBT) pathology. Results The subscapularis tendon tear measured by reader 2 was larger in the study group than in the control group. The prevalence of a tear ( P = 0.006 for reader 1; P = 0.011 for reader 2) and malposition ( P < 0.001 for both readers) of the LHBT were significantly greater in the study group. Conclusion A tear and malposition of the LHBT on MR images may predict the presence of a clinically significant subscapularis tendon tear.

“…The strong relationship of the cysts with the rotator cuff tendons, as well as the TMCs with the subscapularis tendon, was previously reported by several studies [ 22 , 23 , 34 ]. In the current study, the TMC was fewer in the operated shoulder than in the healthy ones.…”

“…The SCI syndrome has been investigated a number of times in a number of studies with a number of parameters. There have been reported results opposite to one another, even in papers with quite similar study designs [ 2 , 6 , 7 , 9 , 17 , 22 , 23 ]. The instinct was mostly towards the existence of this syndrome which paves the way for subscapularis tendon tear.…”

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.

“…Celikyay et al 49 found that the presence of cystic change on or around the lesser tuberosity was strongly associated with LHBT and subscapularis tears. Razmjou et al 46 examined patients with associated rotator cuff disease undergoing arthroscopy and noted 100% sensitivity of MRI for detection of subluxation or dislocation of the LHBT.…”
