Introduction Significant fatty infiltration of the supraspinatus muscle is an important prognostic indicator for the likelihood of supraspinatus tendon repair failure. Two‐dimensional shear wave elastography (2D‐SWE) has the ability to quantitatively assess muscle stiffness. Presented is a pilot study comparing 2D‐SWE with the gold standard of magnetic resonance imaging (MRI) fatty infiltration grading. Methods 2D‐SWE measurements were prospectively obtained in 152 shoulders of participants presenting for shoulder MRI examinations. 2D‐SWE measurements were obtained in the anterior and posterior aspects in the superficial half of the supraspinatus muscle and compared to MRI Goutallier grading of fatty infiltration as assessed by three observers. Region of interest measurements were placed within the elastogram (a) randomly, (b) at the highest colour‐coded region, and (c) within the most common colour code. Results t‐test reveals a statistically significant difference (P = .002) between the mean of eight randomly placed 2D‐SWE samples with Goutallier 1 (mean shear wave speed [SWS] = 2.49) and 2 (mean SWS = 2.24). Although the difference was statistically significant, the large overlap of the SWS distributions between Goutallier grades 1 and 2 indicates that SWS is a poor predictor of Goutallier grading. Conclusion Random SWS sampling throughout the superficial supraspinatus muscle highly correlates with MRI Goutallier grading but lacks accuracy.

Rotator cuff tear is a common shoulder injury that causes shoulder dysfunction and pain. Although surgical repair is the primary treatment for rotator cuff tear, it is well recognized that impaired force exertion of muscles connecting to the involved tendon and subsequent complemental change in the force exertion of synergist muscles persist even after repair. This study aimed to identify the compensation strategy of shoulder abductors by examining how synergist muscles respond to supraspinatus (SSP) muscle force deficit in patients with rotator cuff repair. Muscle shear modulus, an index of muscle force, was assessed for SSP, infraspinatus, upper trapezius, and middle deltoid muscles in repaired and contralateral control shoulders of 15 patients with unilateral tendon repair of the SSP muscle using ultrasound shear wave elastography while the patients passively or actively held their arm in shoulder abduction. In the repaired shoulder, the shear modulus of the SSP muscle declined, whereas that of other synergist muscles did not differ relative to that of the control. To find the association between the affected SSP and each of the synergist muscles, a regression analysis was used to assess the shear moduli at the population level. However, no association was observed between them. At the individual level, there was a tendency of variation among patients with regard to a specific muscle whose shear modulus complementarily increased. These results suggest that the compensation strategy for SSP muscle force deficit varies among individuals, being nonstereotypical in patients with rotator cuff injury.

Objective To investigate muscle stiffness in patients with idiopathic inflammatory myopathies (IIM) using shear wave elastography (SWE) and to correlate the results with muscle strength and MRI features of myositis. Materials and methods Muscle shear wave velocity (SWV) was measured in 23 active IIM patients (13 females, mean age 50.4 ± 16.1 years) and 23 matched healthy controls (13 females, mean age 50.7 ± 16.2 years). The investigated muscles included the vastus lateralis (VL), rectus femoris (RF), vastus medialis (VM) vastus intermedius (VI), biceps femoris (BF), semitendinosus (ST), semimembranosus (SM) and the biceps brachii (BB) scanned during relaxed resting and passive stretching positions. Participants performed multiple tests to evaluate their muscle strength. IIM patients had a thigh MRI to assess degrees of oedema, fatty infiltration and atrophy. Results In the resting position, IIM patients had a 12.9–22.2% significantly lower SWV ( p < 0.05) for the quadriceps and hamstrings, but not BB. There was no difference during passive stretching. The SWV for VL, VI and BF showed moderate correlations with the muscle strength tests ranging from r = 0.47 to r = 0.70 (all p < 0.05). Lower SWV was associated with greater MRI scores of oedema ( p = 0.001) and atrophy ( p = 0.006). However, SWV did not correlate with fatty infiltration ( r < 0.3; p = 0.28), creatine kinase ( r = 0.28; p = 0.19) or disease duration ( r = 0.26; p = 0.24). Conclusion Shear wave elastography may detect abnormal reduced thigh stiffness in IIM patients. SWE measurements were significantly associated with muscle weakness and MRI signs of oedema and atrophy. Future research should investigate this new technology for monitoring disease activity.
