PURPOSE: Early diagnosis of attritional wear of the flexor pollicis longus (FPL) tendon is essential in preventing subsequent tendon rupture. There are currently few objective methods of assessing FPL attrition. We hypothesized that color Doppler imaging could visibly detect FPL tendon attrition, and analyzed our results. METHODS: We evaluated ultrasound imaging of the contact between the FPL tendon and a volar locking plate using the real-time B-mode and Doppler waveforms of the FPL tendon using the continuous Doppler wave mode in 40 patients who underwent fixation of the distal volar locking plate for distal radius fracture...

Acute calcific tendinopathy of the popliteus tendon is a rare medical entity associated with significant patient discomfort. We present the case of a previously healthy 48-year-old female who presented to the emergency department with acute onset of left knee pain. Initial radiographs revealed calcifications within the posterolateral compartment of the knee. Ultrasound imaging demonstrated a swollen and hypoechoic popliteus tendon with an increased color Doppler signal at the periphery of the tendon as well as calcification in the tendon and adjacent soft tissues...

Sonographically detectable intratendinous blood flow (IBF) is found in 50-88% of Achilles tendinopathy patients as well as in up to 35% of asymptomatic Achilles tendons (AT). Although IBF is frequently associated with tendon pathology, it may also represent a physiological regulation e.g. due to increased blood flow in response to exercise. Therefore, this study aimed to investigate the acute effects of a standardized running exercise protocol on IBF assessed with Doppler ultrasound (DU) "Advanced dynamic flow" in healthy ATs...

By virtue of their anatomical location between muscles and bones, tendons make it possible to transform contractile force to joint rotation and locomotion. However, tendons do not behave as rigid links, but exhibit viscoelastic tensile properties, thereby affecting the length and contractile force in the in-series muscle, but also storing and releasing elastic stain energy as some tendons are stretched and recoiled in a cyclic manner during locomotion. In the late 90s, advancements were made in the application of ultrasound scanning that allowed quantifying the tensile deformability and mechanical properties of human tendons in vivo...

Juvenile Idiopathic Arthritis is a heterogeneous condition and an important cause of acquired disability in children. Evidence supports early treatment to prevent future complications. This relies on prompt diagnosis, achieved by a high index of clinical suspicion and supportive evidence, including the detection of joint and or tendon inflammation. Ultrasound is a readily accessible, well tolerated, safe and accurate modality for assessing joints and the surrounding soft tissues. It can also be used to guide therapy into those joints and tendon sheaths, resistant to systemic treatments...

A 50-year-old lady presented with a right foot mass and pain for 1year. Magnetic resonance imaging showed a 3.9×3.2×5cm mass on plantar side of the forefoot deep to the major flexor tendons and plantar aponeurosis and inferior to 1st-4th metatarsals. The mass extended dorsally through the intermetatarsal space to the foot dorsum. Ultrasound guided biopsy was performed, which confirmed it was a fibroma. This case was further complicated by pathological fracture of the 3rd metatarsal. It was resected through a dorsal incision and surgical dislocation of the 2nd and 3rd tarsometatarsal joints...

Post-activation potentiation can improve athletic performance, but the underlying mechanisms are poorly understood. This study investigated the effect of conditioning hops on triceps surae muscle force and tendon strain and its contribution to potentiated stretch-shortening cycle (SSC) performance. Thirty-two subjects participated in two experiments. In both experiments, subjects performed three drop jumps (DJs) after prior conditioning with 10 maximal hops, three unconditioned DJs served as control. Ground reaction forces, kinematics, and triceps surae electromyographic activity were recorded...

PURPOSE: Although platelet-rich plasma (PRP) injection has shown controversial results for the treatment of Achilles tendinopathy, it remains the most used biological treatment. Recent findings seem to demonstrate that the stromal vascular fraction (SVF) within adipose tissue may counteract the impaired tendon homeostasis. The aim of this study was to prospectively compare the efficacy of PRP and SVF injection for the treatment of non-insertional Achilles tendinopathy. METHODS: Fourty-four patients were recruited in the study; 23 of them were assigned to the PRP group whereas 21 to the SVF group, treated unilaterally or bilaterally for a total of 28 tendons per group...

OBJECTIVES: To provide musculoskeletal ultrasound (MSKUS) images of hand anatomy in the position of hemiparetic flexion as a reference for spasticity injections. After a stroke, spasticity can result in anatomic distortion of the hand. Spasticity may require treatment with botulinum toxin or phenol injections. Anatomic distortion may decrease the accuracy of injections. Standard anatomic references are of limited utility because they are not in this spastic hemiparetic position. There presently is no anatomic reference in the literature for these spastic postures...
