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.

“… Subacromial-subdeltoid (SASD) bursitis: SASD bursitis is defined by thickening or distention of the bursa. This can been seen as a low intensity signal in T1 and increased signal intensity on T2, PD-weighted images or PDFS- weighted sequences [ 21 ]. RC tendinosis: On MRI, tendinosis appears as swelling and an increased signal on low TE images, such as PDFS, STIR or T2 with fat suppression or an intermediate signal on T2- weighted images.…”

“… RC tendinosis: On MRI, tendinosis appears as swelling and an increased signal on low TE images, such as PDFS, STIR or T2 with fat suppression or an intermediate signal on T2- weighted images. However, the signal is not as bright as fluid [ 21 , 22 ]. Calcific tendinosis is defined as the deposition of calcium within or around the rotator cuff tendons.…”

BackgroundPrevious studies on shoulder patients have suggested that the prevalence of rotator cuff or bursa abnormalities are weakly related to symptoms and that similar findings are often found in asymptomatic persons. In addition, it is largely unknown whether structural changes identified by magnetic resonance imaging (MRI) affect outcome after treatment for shoulder pain. The purpose of this study was therefore to evaluate the presence of structural changes on MRI in patients with subacromial pain syndrome and to determine to what extent these changes are associated with symptoms and predict outcome after treatment (evaluated by the Shoulder Pain and Disability Index (SPADI)).MethodsA prospective, observational assessment of a subset of shoulder patients who were included in a randomized study was performed. All participants had an MRI of the shoulder. An MRI total score for findings at the AC joint, subacromial bursa and rotator cuff was calculated. Multiple linear regression analysis was applied to examine the relationship between the MRI total score and the outcome measure at baseline and to examine to what extent the MRI total score was associated with the change in the SPADI score from baseline to the one year follow-up.ResultsThere was a weak, inverse association between the SPADI score at baseline and the MRI total score (β = −3.1, with 95% CI −5.9 to −0.34; p = 0.03), i.e. the SPADI score was higher for patients with a lower MRI total score. There was an association between the change in the SPADI score from baseline to the one year follow-up and the MRI total score (β = 8.1, 95% CI -12.3 to −3.8; p < 0.001), with a poorer outcome for patients with a higher MRI total score. Both tendinosis (p = 0.01) and bursitis (p = 0.04) were associated with a poorer outcome after one year.ConclusionsIn this study, MRI findings were significantly associated with the change in the SPADI score from baseline and to one year follow-up, with a poorer outcome after treatment for the patients with higher MRI total score, tendinosis and bursitis on MRI.Trial registrationClinicaltrials.gov no NCT01441830.

“…MRI is an accurate technique used in the evaluation of tendinopathies (Yablon and Jacobson 2015 ) By combining MRI data with reverse engineering, we can look forward to boosting the performance of biomaterials from the architectural and anatomical points of view. The commercial exploitation of such patient-specific implants,that can respect patient anatomy is still an undetermined but their effective production will contribute to improving clinical outcomes and patient quality of life.…”

The treatment of painful chronic tendinopathy is challenging. Multiple non-invasive and tendon-invasive methods are used. When traditional non-invasive treatments fail, the injections of platelet-rich plasma autologous blood or cortisone have become increasingly favored. However, there is little scientific evidence from human studies supporting injection treatment. As the last resort, intra- or peritendinous open or endoscopic surgery are employed even though these also show varying results. This ESSKA basic science committee current concepts review follows the first part on the biology, biomechanics and anatomy of tendinopathies, to provide a comprehensive overview of the latest treatment options for tendinopathy as reported in the literature.
