“…The reliability and validity of elastographic measurements have been investigated in several studies (Park et al, 2014, Yoon et al, 2014). Regarding the muscular tissues, in particular, the crural and the brachial muscles have been shown to have good measurement reliably with satisfactory ICCs (Brandenburg et al, 2015, Koo et al, 2013, Koo et al, 2014, Taniguchi et al, 2015).…”

“…The technique is fast, convenient and applicable to a variety of clinical scenarios in which other approaches would potentially be inadequate. To date, it has been used successfully for breast cancers diagnosis (Athanasiou et al, 2010, Park et al, 2014) and liver fibrosis staging (Ferraioli et al, 2014, Yoon et al, 2014). In addition, quantitative assessments of material properties of muscles have also been investigated by in vivo and in vitro studies (Akagi and Kusama, 2015, Hirata et al, 2015, Hug et al, 2013, Miyamoto et al, 2015, Itoigawa et al, 2015, Koo et al, 2014, Akagi et al, 2012).…”

Ultrasound imaging has been used to evaluate various shoulder pathologies, whereas, quantification of the rotator cuff muscle stiffness using shear wave elastography (SWE) has not been verified. The purpose of this study was to investigate the reliability and feasibility of SWE measurements for the quantification of supraspinatus (SSP) muscle elasticity. Thirty cadaveric shoulders (18 intact and 12 with torn rotator cuff) were used. Intra- and inter-observer reliability was evaluated on an established SWE technique for measuring the SSP muscle elasticity. To assess the effect of overlying soft tissues above the SSP muscle, SWE values were measured with the transducer placed on the skin, on the subcutaneous fat after removing the skin, on the trapezius muscle after removing the subcutaneous fat, and directly on the SSP muscle. In addition, SWE measurements on 4 shoulder positions (0°, 30°, 60°, and 90° abduction) were compared in those with/without rotator cuff tears. Intra- and inter-observer reliability of SWE measurements were excellent for all regions in SSP muscle. Also, removing the overlying soft tissue showed no significant difference on SWE values measured in the SSP muscle. The SSP muscle with 0° abduction showed large SWE values, whereas, shoulders with large-massive tear showed smaller variation throughout the adduction-abduction positions. SWE is a reliable and feasible tool for quantitatively assessing the SSP muscle elasticity. This study also presented SWE measurements on the SSP muscle under various shoulder abduction positions which might help characterize patterns in accordance to the size of rotator cuff tears.

“…For example, lesion depth was one of the factors influencing the false-positive rate of SWE in the breast [20]. This is due to the fact that soft tissue attenuates ultrasound and elastic waves and as a result blocks the acoustic radiation force of shear wave from reaching deep locations [21]. Although the mechanism for differences in reproducibility in the prostate according to location cannot be fully explained, the operator should be aware of this and take extra caution when performing SWE in these areas.…”

“…In particular, shear wave elastography (SWE) evaluates the propagation velocity distribution of the shear waves generated by a focused acoustic push pulse to reconstruct quantitative data of tissue shear modulus 20 . This has been successfully used clinically for breast cancers diagnosis 21 and liver fibrosis staging 22 . In addition, passive stiffness of skeletal muscles, including the supraspinatus muscle, has been assessed using SWE by in vivo and ex vivo studies 23-26 .…”

Purpose To investigate the alteration of passive stiffness in the supraspinatus muscle after double-row (DR) and knotless transosseous-equivalent (KL-TOE) repair techniques, using the shear wave elastography (SWE) in cadavers with rotator cuff tears. We also aimed to compare altered muscular stiffness after these repairs to that obtained from shoulders with intact rotator cuff tendon. Methods Twelve fresh-frozen cadaveric shoulders with rotator cuff tear (tear size; small [6], medium-large [6]) were used. Passive stiffness of four anatomical regions in the supraspinatus muscle was measured based on an established SWE method. Each specimen underwent DR and KL-TOE footprint repairs at 30° glenohumeral abduction. SWE values, obtained at 0°, 10°, 20°, 30°, 60°, and 90° abduction, were assessed in 3 different conditions: preoperative (torn) and postoperative conditions with the 2 techniques. The increase ratio of SWE values after repair was compared among the four regions to assess stiffness distribution. In addition, SWE values were obtained on 12 shoulders with intact rotator cuff tendons as control. Results In shoulders with medium-large size tears, supraspinatus muscles showed an increased passive stiffness after rotator cuff repairs, and this was significantly observed at adducted positions. KL-TOE repair showed uniform stiffness changes among the four regions of the supraspinatus muscle (mean, 189-218% increase after repair), whereas, DR repair caused a significantly heterogeneous stiffness distribution within the muscle (mean, 187-319% after repair, P = 0.002). Although a repair-induced increase in muscle stiffness was observed also in small size tear, there were no significant differences in repaired stiffness changes between DR and KL-TOE (mean, 127-138% and 127-130% after repairs, respectively). Shoulders with intact rotator cuff tendon showed uniform SWE values among the four regions of the supraspinatus muscle (mean, 38.2-43.0 kPa). Conclusion Passive stiffness of the supraspinatus muscle increases after rotator cuff repairs for medium-large size tears. KL-TOE technique for the medium-large size tear provided a more uniform stiffness distribution across the repaired supraspinatus muscles compared to the DR technique. Clinical Relevance Based on this insight investigating rotator cuff muscle stiffness changes, further studies using SWE may determine the optimal repair technique for various sizes of rotator cuff tears.
