“…Prior studies have reported different degrees of relationship between the two. 6,[22][23][24] Regardless of the findings reported by the prior studies, those studies differed in statistical design from the current study. Two prior studies compared the frequency of LT cysts in SBT groups and in normal SBT groups, using w 2 tests.…”

Background: The association between tuberosity cysts and rotator cuff tears (RCTs) and the nature of the major contributing factors to tuberosity cyst formation continue to be controversial. The purpose of our study was to evaluate the strength of associations of RCT and various factors involved in the chronicity of RCT with tuberosity cysts, using magnetic resonance imaging (MRI) and radiographs. Methods: We reviewed consecutive patients with various disease entities between August 2004 and July 2013. After excluding unsuitable patients, this study involved 1007 shoulders of 906 consecutive patients. Each tuberosity cyst was categorized as an anterior greater tuberosity (GT), posterior GT, lesser tuberosity, and bare-area cyst. The odds ratios (ORs) and 95% confidence intervals (CIs) between the tuberosity cysts and various factors were evaluated by logistic regression analyses; p-value was set below 0.05. Results: Anterior GT cysts and posterior GT cysts on MRI or anterior GT cysts on radiographs were significantly associated with supraspinatus tendon (SST) tears (p 0.019) and infraspinatus tendon (IST) tears (p 0.004). Among the shoulder pathologies, RCTs only significantly associated with cyst formation (OR 4.23, 95% CI 3.17-5.65; p < 0.001). The retraction grade of Patte was significantly associated with anterior GT cyst (OR 3.65, 95% CI 2.42-5.48; p < 0.001). Conclusion: Detecting an anterior GT cyst in a radiograph, even a low prevalence, in a patient with symptomatic shoulder indicates a need to consider RCT, especially of the SST, IST, and a high possibility of a retracted tear.

“…Sixteen studies (53%) were conducted prospectively; one study did not mention time of enrollment. Ten studies reported abnormalities in asymptomatic volunteers 1,11,16,18,21,23,24,33,39,47 ; 5 studies (4 of which were cadaver studies) reported prevalence in the general population 10,14,26,28,49 ; 8 included symptomatic patients 6,7,31,36,44,46,50,51 ; and 7 described patients with acute or chronic shoulder dislocations. 3,27,29,38,42,43,52 The majority of the studies used ultrasound to image the rotator cuff (43%; 13 of 30).…”

“…The axillary view can show alterations of the lesser tuberosity, such as irregularities or cysts, which argue in favour of a SSC tendon lesion [21]. Anterior subluxation of the humeral head can also be seen on this view [22].…”

Multi-modal imaging of the subscapularis muscle

The subscapularis (SSC) muscle is the most powerful of the rotator cuff muscles, and plays an important role in shoulder motion and stabilization. SSC tendon tear is quite uncommon, compared to the supraspinatus (SSP) tendon, and, most of the time, part of a large rupture of the rotator cuff. Various complementary imaging techniques can be used to obtain an accurate diagnosis of SSC tendon lesions, as well as their extension and muscular impact. Pre-operative diagnosis by imaging is a key issue, since a lesion of the SSC tendon impacts on treatment, surgical approach, and post-operative functional prognosis of rotator cuff injuries. Radiologists should be aware of the SSC anatomy, variability in radiological presentation of muscle or tendon injury, and particular mechanisms that may lead to a SSC injury, such as coracoid impingement.Teaching Points• Isolated subscapularis (SSC) tendon tears are uncommon. • Classically, partial thickness SSC tendon tears start superomedially and progress inferolaterally. • Long head of biceps tendon medial dislocation can indirectly signify SSC tendon tears. • SSC tendon injury is associated with anterior shoulder instability. • Dynamic ultrasound study of the SSC helps to diagnose coracoid impingement.

Cysts Within and Adjacent to the Lesser Tuberosity and Their Association With Rotator Cuff Abnormalities

Abstract: Cysts located within the lesser tuberosity are rare and are indicative of subscapularis and supraspinatus tendon abnormalities.
