INTRODUCTION: The standard therapy of intra-articular and extra-articular distal radius fractures consists of open reduction and stabilization using palmar osteosynthesis with an angularly stable plate. The integrity of the flexor pollicis longus tendon (FPLT) may be mechanically affected by the plate, with rupture rates between 1 and 12% reported in the literature, occurring during a postoperative time period from 4 to 120 months. The aim of this study was to investigate the position of the tendon in relation to the distal edge of the plate using high-resolution ultrasonic imaging...

We report two rare cases of existing or worsening symptoms due to Kienböck's disease after distal radius fracture (DRF). During examination, radiographs show changes in the lunate bone; there was persistent wrist pain after treatment for DRF. In each case, surgeries were performed: A combined therapy (bone marrow transfusion, bone peg graft, external fixation, and low intensity pulsed ultrasound) for one, as well as carpal coalition for another. The etiology of these case presentations suggest that a compression fracture of the lunate due to a DRF resulted in softening and sclerosis...

The radial nerve has a long and tortuous course in the upper limb. Injury to the nerve can occur due to a multitude of causes at many potential sites along its course. The most common site of involvement is in the proximal forearm affecting the posterior interosseous branch while the main branch of the radial nerve is injured in fractures of the humeral shaft. Signs and symptoms of radial neuropathy depend upon the site of injury. Injury to the nerve distal to innervation of triceps brachii results in loss of extensor function with sparing of function of the triceps resulting in the characteristic 'wrist drop'...

Introduction: The incidence rate of true non-traumatic radial artery aneurysms (RAAs) is low, and very few cases have been described. The majority are traumatic in origin and are iatrogenic pseudo-aneurysms following arterial cannulation. However, other rare causes such as vascular tumors, connective tissue diseases, and occupational injury have also been reported. Only eight cases were reported as idiopathic true RAA. Herein, I describe a case of true idiopathic distal RAA, which was managed by surgical repair...

BACKGROUND: Proximal brachial plexus blocks can lead to an extended period of motor paralysis and delay the return of motor function. This could influence patient satisfaction, and extend hospitalizations. The aim of the study is to compare a selective distal nerve block of the arm to a proximal axillary block, both ultrasound-guided, in terms of their motor block intensity of the elbow. Our hypothesis is that a selective nerve block of the arm would result in a different motor block of the elbow, compared to the axillary block...

Background: High frequency ultrasound is often used to measure the thickness of fluid in peripheral joints and bursae of healthy asymptomatic populations. Two major steps critical to this procedure are obtaining the detection rates and analyzing the relevant factors. Methods: Healthy Chinese adult volunteers with no history of arthritis, past trauma or surgery and joint pain were enrolled in this study. Ultrasonography was performed on the bilateral shoulders, elbows, wrists, metacarpophalangeal joints (MCP) 1-5, proximal interphalangeal joints (PIP) 1-5, distal interphalangeal joints (DIP) 2-5, suprapatellar knees, ankles, metatarsophalangeal joints (MTP) 1-5, subacromial and subdeltoid bursae, deep infrapatellar bursae, retrocalcaneal bursae and long biceps tendons in B mode...

OBJECTIVES: To use high-resolution imaging to characterise palindromic rheumatism (PR) and to compare the imaging pattern observed to that seen in new-onset rheumatoid arthritis (NORA). METHODS: Ultrasound (US) assessment of synovitis, tenosynovitis and non-synovial extracapsular inflammation (ECI) was performed during and between flares in a prospective treatment-naive PR cohort. MRI of the flaring region was performed where possible. For comparison, the same US assessment was also performed in anticyclic citrullinated peptide (CCP) positive individuals with musculoskeletal symptoms (CCP+ at risk) and patients with NORA...

Ellis Niemantsverdriet, Annette H M van der Helm-van Mil
Tenosynovitis is traditionally recognised at physical examination in patients with inflammatory rheumatic diseases, such as, e.g. psoriatic arthritis and (longstanding) rheumatoid arthritis (RA). The increasing use of sensitive imaging techniques (ultrasound, magnetic resonance imaging (MRI)) has recently revealed that subclinical tenosynovitis is prevalent in early RA and in patients in different phases of RA development (asymptomatic state, arthralgia, early arthritis). In this review, the recent findings on MRI-detected tenosynovitis and associations with RA development are highlighted, and an overview of the most reported inflamed tendon locations within the hand and wrist of patients in different disease phases is provided...

With the ability to detect volumetric changes of contracting muscles, ultrasound (US) was a potential technique in the field of human-machine interface (HMI). Compared to the US imaging (B-mode US), the signal from a static single-element US transducer, A-mode US, was a more cost-effective and convenient way towards the real-world application, particularly the wearables. This study compared the performance of the single-channel A-mode US with single-channel surface electromyogram (sEMG) signals, one of the most popular signal modalities for wrist and finger gesture recognition...
