“…Elastographic quantification of pathological tendon elasticity has already been studied in humans, and it has been verified that in acute Achilles tendon injuries and in cases of Queravin's tenosynovitis, there is a significant reduction in stiffness, observed by this imaging technique 25,26 . Our findings also demonstrate that quantitative analysis using ARFI elastography increases the reliability of the results obtained by the qualitative study, in addition to establishing a cutoff point to determine the lesion in its acute form (T1 and T2), with good sensitivity and specificity values.…”

The objectives of this prospective, experimental study were to describe changes in the stiffness of the equine superficial digital flexor tendon (SDFT) after induced injury, deep digital flexor tendon (DDFT), accessory ligament (AL‐DDFT), and suspensory ligament (SL) during 90 days of healing using acoustic radiation force impulse (ARFI) elastography. Eight healthy horses were selected. Preinjury B mode and ARFI evaluations were performed bilaterally in the palmar metacarpal region. Injury was induced only on the left forelimb (G2) by a single injection of collagenase in SDFT, 15 cm distal to the accessory carpal bone. The right forelimb was used as a control (G1). Evaluations were performed at eight timepoints: one before injury (T0) and seven (T1‐T7) after injury (3, 15, 30, 40, 60, 75, and 90 days post‐induction). Tendinopathies were visualized as hypoechoic areas with loss of parallel tendon fiber pattern. Injured SDFTs presented mainly cool colors (soft) from T1 to T3, and from T4, there was an increase in warm colors (hard), close to the appearance of tendons of G1. In the first four timepoints, there was a decrease in stiffness compared to G1 (P < 0.001). On T1 and T2, a cutoff value <6.21 m/s to determine tendinopathy of the SDFT was established (75.8% sensitivity and 92.03% specificity). Stiffness changes in the DDFT, AL‐DDFT, and SL of injured limbs occurred at different timepoints. Tendinopathy significantly altered the stiffness of the injured tendon and the adjacent tissues. ARFI made it possible to detect these changes, helping to monitor the reparation of this injury.

“…While this preliminary case-control study had a limited sample size, the finding of stiffer tendons with AIA was intriguing given that affected tendons have been shown to be softer than healthy normal tendons in other studies [16]. For example, Turkay et al demonstrated that adult patients with de Quervain tenosynovitis had slower SW velocities (suggesting softer tendons) than healthy adults in the first extensor compartment of the hand [17]. Conversely, SWE studies of the median nerve in the assessment of carpal tunnel syndrome have shown increased SW velocities in patients relative to controls [18].…”

Aromatase inhibitor-induced arthralgia (AIA) comprises significant, activity-limiting musculoskeletal symptoms, including joint pain, myalgia, and joint stiffness. We conducted a prospective feasibility study in postmenopausal women diagnosed with early-stage (0–3) hormone receptor positive (HR+) breast cancer who were candidates for treatment with adjuvant AI therapy (n = 16). Tendons of the hands and wrists and the median nerve were imaged using gray-scale and power Doppler ultrasound (US) and US SWE. Arthralgia symptoms were evaluated using the Breast Cancer Prevention Trial (BCPT) Symptom Checklist musculoskeletal subscale (MS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and stiffness subscales. At baseline, there were significant differences in the SW velocities of tendons between dominant and nondominant hands. Increased velocity in 2 of 6 tendons and the median nerve was associated with greater pain at baseline, whereas slower velocity of the extensor digitorum tendon (suggesting decreased stiffness) was associated with a higher WOMAC stiffness score. Increased SW velocity (suggestive of increased stiffness) at baseline in the abductor pollicis longus tendon was associated with a worsening of all three pain and stiffness measures by 6 months. Future studies should evaluate SWE scores related to AIA outcomes in a larger sample size.

“…SWE was also used to identify the increased stiffness of tendons and their sheath in 40 patients with DQD symptoms in comparison with 40 healthy subjects. The authors found significant differences between the two groups with a SWE value of 40.5kPA as the cut-off for the diagnosis of DQD [46]. US-guided procedures with a steroid injection or release of the retinaculum have proven efficacy for symptom relief, thus avoiding the need for surgery.…”
