“…Fontenelle et al compared the mechanical properties of the supraspinatus tendon in two different age groups using SWE ( 2 ). They evaluated the right shoulder of 38 healthy individuals between 20 and 35 years old and over 60 years of age in a level of evidence III study.…”

“…One study showed a softer supraspinatus tendon after 60 years of age. Another study showed increased stiffness in LHBT in tendinosis conditions (1,2). In postsurgical status after supraspinatus tendon repair, SWE seems to show different short-term and long-term results concerning two newly published articles (8,11).…”

“…Dynamic SE (SWE) uses an acoustic radiation force to create and propagate shear waves. This method measures the shear wave speed to evaluate mechanical properties of tissues to visualize tissue displacements to allow the examiner to infer information regarding the tissular biomechanics (1)(2)(3). Both methods are operator-dependent and have yielded favorable inter-rater reliability (4,5).…”

Sonoelastography is a relatively new non-invasive imaging tool to assess the in vivo qualitative and quantitative biomechanical properties of various tissues. Two types of sonoelastography (SE) are commonly explored: strain and shear wave. Sonoelastography can be used in multiple medical subspecialties to assess pathological tissular changes by obtaining mechanical properties, shear wave speed, and strain ratio data. Although there are various radiological imaging methods, such as MRI or CT scan, to assess musculoskeletal structures (muscles, tendons, joint capsules), SE is more accessible since this approach is of low cost and does not involve radiation. As of 2018, SE has garnered promising data in multiple studies. Preliminary clinico-radiological correlations have been established to bridge tissue biomechanical findings with their respective clinical pathologies. Specifically, concerning the shoulder complex, recent findings have described mechanical tissue changes in shoulder capsulitis. The long head of the biceps and supraspinatus SE were among the recently studied structures with conditions regarding impingement, tendinosis, and tears. Since ultrasonography has established itself as an important tool in shoulder evaluation, it completes the history and physical examination skills of the clinicians. This study will provide an update on the most recent findings on SE of shoulder structures.

“…This may affect the SWE values of tissues. In a study, Fontenella et al[ 23 ] analyzed of the supraspinatus tendon in differential age groups and they found a difference between the means of the shear modulus measured by the SSI elastography, indicating a significant decrease of the shear modulus with the chronological age progression. The patients and healthy volunteers in our study were in similar age groups and were all male.…”

Anterior shoulder instability is the most common form of shoulder instability and is seen in 1.7 to 2% of the general population. [1][2][3] Traumatic shoulder instability or dislocation is often seen as an avulsion of the anterior inferior labrum and the lesion is called Bankart lesion. [4] Static factors such as the glenoid labrum, capsuloligamentous structures, bone formations forming the joint, dynamic factors such as the muscles forming the shoulder girdle, negative intra-articular pressure, and joint adhesion-cohesion forces stabilize the glenohumeral joint. [5] As the soft tissues play an active role in shoulder stabilization, the deterioration of the balance in these soft tissues plays an important role in the formation of traumatic or atraumatic dislocations.Objectives: This study aims to evaluate the soft tissue stiffness which has a prominent role in shoulder instability using ultrasound (US) shear wave elastography (SWE) and to compare the results with healthy shoulders.Patients and methods: Between December 2018 and January 2020, a total of 33 male patients (mean age: 26±4.3 years; range, 18 to 35 years) who underwent arthroscopic repair for traumatic isolated anterior glenohumeral instability were included in this prospective study. The shoulder girdle was evaluated with US SWE in patients with traumatic anterior instability. Deltoid (D), supraspinatus (SS), infraspinatus (IS), subscapularis (SSC), and long head of biceps (LHB) tendons forming the shoulder girdle and anterior labrum (L) were evaluated with SWE. The elasticity and velocity of the tissues were quantitatively measured. The operated shoulders of 33 patients due to isolated traumatic anterior instability were named Group 1, while the healthy shoulders of these patients were named Group 2. Thirty volunteers with healthy shoulders were considered as the control group (Group 3, n=30).Results: All three groups were compared in terms of SS, D, LHB, and SSC tendon velocity and elasticity; however, no statistically significant difference was observed among the groups (p<0.05). The anterior labrum of these three groups did not significantly differ in terms of SWE measurements (p<0.05). Conclusion:The stiffness of shoulder girdle muscle tendons and labrum measured with US SWE does not constitute a risk factor for traumatic anterior shoulder instability.
