OBJECTIVE: The present study was performed to localize the articular deposition of monosodium urate (MSU) crystal in joints. We compare the detection efficiencies of dual-energy CT (DECT) and ultrasound scans. METHODS: Analyses by DECT and ultrasound were performed with 184 bilateral joints of the lower limbs of 54 consecutive gout patients. All joints were categorized into (1) knee, (2) ankle, (3) MTP1, and (4) MTP2, and sorted into those with and those without detectable MSU deposition...

BACKGROUND: Unilateral lower limb amputation can alter the tissue morphology leading to increase future risk of degenerative secondary disorders. METHODS: Thirty-four consecutive male patients with unilateral lower limb amputations of different levels and 34 well matched male controls were included. To explore whether the ankles of traumatic lower limb amputees were undergoing morphological changes, three different tissue types i.e. talar cartilage, plantar fascia and Achilles tendon thicknesses in the intact limb of the lower limb amputee and healthy controls were measured by using ultrasound...

Chondroma is a benign cartilaginous tumor composed of mature hyaline cartilage and represents only 2.38% of all osteocartilaginous tumors; cases that arise in the preauricular region are rarely found in the literature. This article presents an 80-year-old man with preauricular swelling on the right side and pain with no limitation of joint motion. This patient was evaluated by preoperative clinical manifestation, fine needle aspiration, ultrasound, and magnetic resonance imaging (MRI) scans. The MRI shows a solid lobulated lesion between the masseter muscle and the parotid gland whereas fine-needle aspiration did not provide a diagnosis...

BACKGROUND: Prevention of hemarthrosis is the key factor in the adequate management of people with hemophilia (PWH). If hemarthrosis occurs, early diagnosis of joint damage is essential to make personalized treatments. This study is aimed at gaining an understanding of the ability of point-of-care ultrasound (US) using the `Hemophilia Early Arthropathy Detection with Ultrasound´ (HEAD-US) protocol to detect abnormalities in joints without history of hemarthrosis and clinically asymptomatic joints of PWH...

Chest wall neoplasms mainly include malignancies, metastatic in particular. Differential diagnosis should include clinical data; tumor location, extent, delineation; the degree of homogeneity; the presence of calcifications; the nature of bone destruction and the degree of vascularization. The aim of the paper is to present both the benefits and limitations of ultrasound for the diagnosis of chest wall neoplasms. The neoplastic process may be limited to the chest wall; it may spread from the chest wall into the intrathoracic structures or spread from the inside of the chest towards the chest wall...

Enzyme-induced articular cartilage degeneration resembling osteoarthritis was evaluated using a newly defined acoustic parameter, the "averaged magnitude ratio" (AMR), which has been suggested as an indicator of articular cartilage degeneration. In vitro experiments were conducted on porcine cartilage samples digested with trypsin for 2 h (n = 10) and 4 h (n = 13) and healthy control samples (n = 13). AMR was determined with 15- and 25-MHz ultrasound, and the integrated reflection coefficient (IRC) and apparent integrated backscattering coefficient (AIB) were also calculated for comparison...

Applying cricoid pressure is a common practice when intubating patients thought to be at risk of pulmonary aspiration. Recently, the perceived benefits of applying cricoid pressure have been questioned. Prior research has shown that cricoid pressure is applied incorrectly and that palpation of adjacent anatomy of the cricothyroid membrane is also inaccurate. We compared physical palpation to ultrasound for identifying the location of the cricoid cartilage using a total of 50 assessments. The median distance to target was 10 mm...

A 56-year-old man presented with a painless scrotal lump, enlarging over the preceding 1 month. The lump was roughly 1 cm in size, and located in his left hemiscrotum and separate from the testis. An ultrasound revealed an echogenic focus with dystrophic tissue calcification. Subsequent surgical excision and histopathological analysis revealed it to be late-stage myositis ossificans, a benign, extraosseous formation of the bone or cartilage. We report of only the second described case of myositis ossificans of the spermatic cord in the literature to date...

Background Despite being promising, the use of ultrasound (US) in the assessment of musculoskeletal manifestations of systemic lupus erythematosus (SLE) is still limited. Literature on this topic is scarce and the spectrum and clinical relevance of US abnormalities has not yet been outlined. With this paper, we aim to explore the panel of joint and tendon US findings in a group of SLE patients. Methods Twenty-five consecutive SLE patients, with current or medical history of musculoskeletal symptoms, were studied...

Using the thyromental distance (TMD) measured based on the ultrasonographic location of the thyroid cartilage prominence as the criterion, we investigated the accuracy of TMD measurement by surface landmark identification of the thyroid cartilage prominence. Twenty-nine anesthetist resident volunteers were recruited, including 10 first-year residents, 9 second-year residents and 10 third-year residents. Each volunteer measured the other 28 volunteers' TMD. Then, the thyroid cartilage prominence of each volunteer was identified by ultrasonography of the junction of the vocal cord and thyroid cartilage, and the TMD was measured precisely...

OBJECTIVE: To compare ultrasound-detected abnormalities, namely double contour sign (DCS) and hyperechoic aggregates (HAGs), at two sites (knee and first metatarsophalangeal [1st MTP] joints) versus six sites (knee joint, 1st MTP joint, radiocarpal joint, talar joint, patellar tendon and triceps tendon) in gout patients. METHODS: Forty-seven clinically diagnosed gout patients and 50 subjects (serum uric acid < 7 mg/dL) as controls were included. DCS was looked for at three articular cartilage sites (first metatarsal, tibiotalar and femoral condyle), whereas HAGs were looked for at one joint site (radiocarpal joint) and two tendon sites (patellar tendon and triceps tendon)...

BACKGROUND: Assessment of the joint cartilage using ultrasound (US) imaging is important. OBJECTIVE: Our aim was to investigate the reliabilities of ultrasonographic measurements for talus dome (TCT) and metacarpal cartilage thicknesses (MCT). METHODS: Twenty healthy volunteers were recruited in the study. Every day, five physiatrists measured eight joint cartilage thicknesses. They repeated all the measurements in five consecutive days. RESULTS: Intra-observer intraclass correlation coefficient (ICC) values were "excellent" for all MCTs, except for the 3rd left MCT on the 1st day, 4th left MCT on the 1st day and 4th right MCT on the 3rd day which were "good"...

BACKGROUND: Matching the frequency of the driving force to that of the system's natural frequency of vibration results in greater amplitude response. Thus we hypothesize that applying ultrasound at the chondrocyte's resonant frequency will result in greater deformation than applying similar ultrasound power at a frequency outside of the resonant bandwidth. Based on this resonant hypothesis, our group previously confirmed theoretically and experimentally that ultrasound stimulation of suspended chondrocytes at resonance (5 MHz) maximized gene expression of load inducible genes...

This study investigated the therapeutic potential of low-intensity pulsed ultrasound (LIPUS) in post-traumatic osteoarthritis (PTOA). Intra-articular fracture of the medial tibial plateau was surgically created in 30 rats. LIPUS was applied to the operated joints either for the first 2 wk (LIPUS1-2 group) or in weeks 4 and 5 after intra-articular fracture (LIPUS4-5 group). In controls, the operated knees were not treated with LIPUS (LIPUS0 group). The rats were monitored with weekly gait analysis and euthanized at week 8...

Ultrasound has become the primary diagnostic tool in traumatic, inflammatory and degenerative soft tissue conditions. It is also used to monitor the condition of joints, ligaments, cartilage and muscles. Its widespread availability as well as cases of unsatisfactory quality of equipment and the lack of appropriate training of ultrasound examiners are reasons why standards need to be set for equipment requirements, the scope of ultrasound assessment and examiner's experience. The paper discusses ultrasound criteria that are common for many specialties as well as detailed criteria for the examined regions and structures along with their description...

BACKGROUND: Chronic arthropathy occurs in approximately two thirds of patients with hereditary haemochromatosis (HH). The aim was to study inflammatory and structural lesions in patients with HH with (HH-A) and without arthropathy (HH-WA) using ultrasonography. METHODS: This was a cross-sectional study of 26 patients with HH-A, 24 with HH-WA and 37 with hand osteoarthritis (HOA). Clinical examination was performed in 68 joints, and we retrieved data on hand function, pain and global disease activity (all using a visual analogue scale (VAS)), morning stiffness and ferritin levels...

The effects of low intensity pulsed ultrasound (LIPUS) on proliferation and chondrogenic differentiation of human mesenchymal stem cells (hMSCs) seeded on 3D printed poly-(ethylene glycol)-diacrylate (PEG-DA) scaffolds with varying pore geometries (square and hexagonal channels) were investigated. The scaffold with square pores resulted in higher hMSC growth and chondrogenic differentiation than a solid or a hexagonally porous scaffold. The optimal LIPUS parameters at 1.5 MHz were found to be 100 mW/cm(2) and 20% duty cycle...
