Abstract
OBJECTIVE Given the ability of ultrasound imaging (USI) to depict tissue-specific morphological changes before the onset of pain and before the point of irreversible structural damage, USI could play a fundamental role in earlier detection and assessment of foot osteoarthritis (OA). The current guidelines require further refinement of anatomical landmarks to establish a standardized imaging procedure to improve the interpretability and reproducibility between studies evaluating the first metatarsophalangeal joint (MTPJ). The aims were to develop an USI acquisition procedure and grading system to examine OA features in the first MTPJ and to determine intra-examiner and inter-examiner reliability of a newly developed USI acquisition procedure. DESIGN Thirty participants with first MTPJ OA confirmed radiographically with the use of the La Trobe Foot Atlas were included. An experienced sonographer applied a newly developed USI procedure to examine the following features: joint effusion, synovial hypertrophy, synovitis, joint space narrowing, osteophytes, and cartilage thickness. A semiquantitative grading system was applied to all features. A continuous measure was also examined for osteophyte size, joint space narrowing, and cartilage thickness. To determine the intra-examiner and inter-examiner reliability, an experienced radiologist and sonographer applied the developed grading system to the images acquired from two imaging sessions. Intra-examiner and inter-examiner reliability were calculated using intraclass correlation coefficients (ICCs). RESULTS ICCs for intra-examiner between session reliability ranged from 0.58 to 0.92 for semiquantitative grading and 0.39 to 0.94 for continuous measures. Joint effusion and osteophytes achieved the highest intra-examiner reliability (ICC = 0.78-0.94). ICCs for session one inter-examiner reliability ranged from 0.61 to 1.0 for semiquantitative grading; all continuous measures had an ICC of 1. ICCs for session two inter-examiner reliability ranged from 0.55 to 1.0 for semiquantitative grading and 0.9 to 0.97 for continuous measures. Inter-examiner reliability was good for grading joint effusion (ICC = 0.55-0.62) and was excellent for all other USI features (ICC = 0.77-1.0). CONCLUSION The USI acquisition procedure and grading system are reliable in evaluating first MTPJ OA features in participants with radiologically confirmed OA. The study will inform the methodological development of an ultrasound atlas for grading the degree of osteoarthritic change in the first MTPJ.

Interobserver reliability of classifying shoulder calcific tendinopathy on plain radiography and ultrasound. Rev Esp Cir Ortop Traumatol (Engl Ed) 2023:S1888-4415(23)00263-1. [PMID: 38110150 DOI: 10.1016/j.recot.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 11/22/2023] [Accepted: 12/11/2023] [Indexed: 12/20/2023] Open
Abstract
INTRODUCTION Shoulder calcific tendinopathy is a frequent cause of shoulder pain. Diagnosis is usually based on ultrasound (US) and/or X-ray. US is considered an inherently operator-dependent imaging modality and, interobserver variability has previously been described by experts in the musculoskeletal US. The main objective of this study is to assess the interobserver agreement for shoulder calcific tendinopathy attending to the size, type, and location of calcium analyzed in plain film and ultrasound among trained musculoskeletal radiologists. MATERIAL AND METHODS From June 2018 to May 2019, we conducted a prospective study. Patients diagnosed with shoulder pain related to calcific tendinopathy were included. Two different experienced musculoskeletal radiologists evaluated independently the plain film and the US. RESULTS Forty patients, with a mean age of 54.6 years, were included. Cohen's kappa coefficient of 0.721 and 0.761 was obtained for the type of calcium encountered in plain film and the US, respectively. The location of calcification obtained a coefficient of 0.927 and 0.760 in plain film and US, respectively. The size of the calcification presented an intraclass correlation coefficient (ICC) of 0.891 and 0.86 in plain film and US respectively. No statistically significant differences were found in either measurement. CONCLUSION This study shows very good interobserver reliability of type and size measurement (plain film and US) of shoulder calcifying tendinopathy in experienced musculoskeletal radiologists.

Abstract
As a radiation-free and dynamic imaging tool, musculoskeletal ultrasound improves diagnostic and therapeutic safety. With its growing application, the demand for training opportunities rises rapidly. Therefore, this work was aimed at mapping the current state of musculoskeletal ultrasonography education. A systematic literature search was conducted in January 2022 in the medical databases Embase, PubMed and Google Scholar. By use of specifically selected keywords, matching publications were filtered; then abstracts were screened independently by two authors and the inclusion of each publication was checked against pre-defined criteria according to the PICO (Population, Intervention, Comparator, Outcomes) scheme. Full-text versions of included publications were reviewed, and relevant information was extracted. Finally, 67 publications were included. Our results revealed a wide variety of course concepts and programs that have been implemented in different disciplines. Musculoskeletal ultrasonography training especially addresses residents in rheumatology, radiology and physical medicine and rehabilitation. International institutions, such as the European League Against Rheumatism and the Pan-American League of Associations for Rheumatology, have suggested guidelines and curricula to promote standardized ultrasound training. The development of alternative teaching methods incorporating e-learning, peer teaching and distance learning on mobile ultrasound devices and the determination of international guidelines could facilitate overcoming the remaining obstacles still to be passed. In conclusion, it can be stated that there is a broad consensus that standardized musculoskeletal ultrasound curricula would improve training and facilitate the implementation of new training programs.

Abstract
Purpose: Bursitis is a common musculoskeletal cause of shoulder pain and treatment varies, thus correctly diagnosing and grading bursitis is paramount in deciding management. Our aim was to assess reliability in grading shoulder bursitis on ultrasonography among fellowship trained musculoskeletal radiologists at our institution. Methods: Retrospective study of patients diagnosed with bursitis on ultrasonography. Single-sonographic images of the subacromial-subdeltoid bursa were collected for each patient and randomized to form a test-bank of varying degrees of bursitis. Three months after the test was administered, the cases were randomized and readministered. The radiologists graded each case as: within normal limits, mild, moderate or severe. Intraobserver variability was measured using Cohen's kappa coefficient. Linear regression model was performed to assess correlation between years of experience and kappa. Results: 10 radiologists reviewed 70 cases of bursitis. Kappa values ranged from .53 to .91, indicating 'moderate' to 'almost perfect' variability amongst radiologists. A moderate positive correlation of improving variability (r = .69) with increasing years of experience exists. Conclusion: Fellowship trained musculoskeletal radiologists were able to grade shoulder bursitis with moderate to almost perfect variability, with a positive correlation of improved variability with increasing experience. This may help clinicians choose the correct treatment more confidently in their patients with shoulder pain.

Immediate Effects of Long-Axis Talocrural Thrust Manipulation on the Length of the Anterior Talofibular and Calcaneofibular Ligaments Measured With Musculoskeletal Ultrasound Imaging. J Manipulative Physiol Ther 2022; 45:153-162. [PMID: 35753871 DOI: 10.1016/j.jmpt.2022.03.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 03/22/2022] [Accepted: 03/22/2022] [Indexed: 11/22/2022]
Abstract
OBJECTIVE The aim of the present study was to measure the immediate effect of a thrust manipulation on the length of the anterior talofibular and calcaneofibular ligaments in healthy patients. METHODS A convenience sample of 47 healthy patients were recruited for this quasi-experimental study. The patients had an age range from 22 to 54 years, with a mean age of 30.36 years. There were 23 female patients and 24 male patients. Musculoskeletal ultrasound imaging was used to measure the length of the anterior talofibular and calcaneofibular ligaments before and immediately after a high-velocity long-axis thrust manipulation of the talocrural joint during various validated test positions. RESULTS A single long-axis thrust manipulation did not result in a significant change in the length of the anterior talofibular ligament (P = .325). Additionally, there was no significant difference in calcaneofibular length after a long-axis thrust manipulation (P = .26). CONCLUSION The results indicate that the length of the anterior talofibular and calcaneofibular ligament did not significantly change after a single long-axis thrust manipulation of the talocrural joint in healthy patients. It appears that the joint capsule of the talocrural joint reached end-range during the manipulation before the ligament undergoes plastic length changes; thus, the increase in joint range of motion after a thrust manipulation was probably not due to increased plastic length changes of the anterior talofibular and calcaneofibular ligaments.

Abstract
Ultrasound can be used to assess injury and structural changes to the soft-tissue structure of the foot. It may be useful to assess the feet of people with diabetes who are at increased risk of plantar soft-tissue pathological changes. The aim of this study was to determine if ultrasound measurements of plantar soft-tissue thickness and assessments of tissue acoustic characteristics are reliable in people with and without diabetes mellitus. A repeated measures design was used to determine intra-observer reliability for ultrasound measurements of plantar skin and fat pad thickness and intra- and inter-observer reliability of plantar skin and fat pad tissue characterisation assessments made at foot sites which are at risk of tissue injury in people with diabetes. Thickness measurements and tissue characterisation assessments were obtained at the heel and forefoot in both the unloaded and compressed states and included discrete layers of the plantar tissues: skin, microchamber, horizontal fibrous band, macrochamber and total soft-tissue depth. At each site, relative intra-observer reliability was achieved for the measurement of at least one plantar tissue layer. The total soft-tissue thickness measured in the unloaded state (ICC 0.925-0.976) demonstrated intra-observer reliability and is the most sensitive for detecting small change on repeated measures. Intra-observer agreement was demonstrated for tissue characteristic assessments of the skin at the heel (k = 0.70), fat pad at the lateral sesamoid region (k = 0.70) and both skin and fat pad at the second (k = 0.80, k = 0.70 respectively) and third metatarsal heads (k = 0.90, k = 0.79 respectively). However, acceptable inter-observer agreement was not demonstrated for any tissue characteristic assessment, therefore the use of multiple observers should be avoided when making these assessments.

Abstract
OBJECTIVES To systematically review the literature on inter- and intra-rater reliability of scoring ultrasound and MRI changes in hand osteoarthritis (OA). METHODS Medline, EMBASE, CINHAL, Web of Science and AMED were searched from inception to January 2020. Kappa (K), weighted Kappa (Kw) and intra-class correlation coefficients (ICC) for dichotomous, semi-quantitative and summated scores respectively, and their 95% confidence intervals (CI) were pooled using random-effects model. Heterogeneity between studies was assessed and reliability estimates were interpreted using Landis-Koch's classification. RESULTS Fifty studies met the inclusion criteria (33 ultrasound, 21 MRI). The pooled K(95% CI) for inter-rater reliability was substantial for ultrasound-detected osteophytes [0.66 (0.54, 0.79)], grey-scale synovitis (GSS) [0.64 (0.32, 0.97)], and power Doppler (PD) [0.76, (0.47, 1.05)]; whereas intra-rater reliability was almost perfect for osteophytes [0.82 (0.80, 0.84)], central bone erosions (CBEs) [0.83 (0.78, 0.89)], and effusion [0.83 (0.74, 0.91)]; and substantial for GSS [0.64 (0.49, 0.79)] and PD [0.70 (0.59, 0.80)].Inter-rater reliability for dichotomous assessment was substantial for MRI-detected CBEs [0.75 (0.67, 0.83)] and synovitis [0.69 (0.51, 0.87)]; slight for osteophytes [0.14 (0.04, 0.25)]; and almost perfect for sum score of osteophytes, CBEs, joint space narrowing (JSN), and bone marrow lesions (BMLs) (0.81-0.89). Intra-rater reliability was almost perfect for sum score of MRI synovitis [0.92 (0.87, 0.96)], BMLs [0.88 (0.78, 0.98)], osteophytes [0.86 (0.74, 0.98)], CBEs [0.83 (0.66, 1.00)] and JSN [0.91 (0.87, 0.91)]. CONCLUSION Ultrasound and MRI are reliable in detecting hand OA features. Ultrasound may be preferred due to low-cost and increasing availability.

Abstract
PURPOSE Given the increasing research interest in ultrasound plantar aponeurosis (PA) thickness measurements, this study aimed to analyze the inter and intra-rater reliability of independent sonograms and to identify the error related to the image analysis procedure. METHODS Twenty-one healthy men participated in this study. Imaging of PA consisted of two independent sonograms per subject. Two raters (R1 and R2) evaluated each sonogram twice using standardized steps. Precision of the image analysis procedure was analyzed using the Bland and Altman plot and Intraclass Correlation Coefficient (ICC). Agreement estimates and ICC were used to assess absolute and relative inter and intra-rater reliability. RESULTS Reliability of PA thickness was found to depend strongly on the number of images acquired per subject. Intra-rater agreement for single measurements were 0.696 (R1) and 0.495 (R2), whereas average measurements yielded values of 0.821 (R1) and 0.662 (R2), respectively. Precision within a sonogram varied from ICC values of 0.873 to 0.960 (intra-rater) and 0.670 to 0.822 (inter-rater). CONCLUSION Most part of the error in PA thickness measurements seems to be related to the sonogram acquisition process and not to the visual inspection of the image. To minimize error, average values of a minimum of two images per subject should be used. The moderate agreement between raters found in this study ratifies the need of all measurements being made by the same rater or group of raters. If a single rater evaluates all subjects, performing multiple measurements over one image does not seem to affect ICC as much as acquiring multiple images.

Abstract
The presence of blood or calcium in the musculoskeletal (MSK) system may be linked to specific pathological conditions. The ability of MRI for calcium detection is usually limited compared with other techniques such as CT. In a similar manner, the accuracy of MRI for detection and evaluation of hemorrhage in soft tissues is closely linked to the degree of degradation of blood products. Blood and calcium are substances that cause local inhomogeneity of the magnetic field resulting in susceptibility artifacts. To try to evaluate these substances, specific MRI sequences which are highly sensitive to these local magnetic field inhomogeneities such as Susceptibility Weighted Imaging (SWI) have been developed and successfully applied in the Central Nervous System, but scarcely used in MSK. SWI may increase the overall sensitivity of MRI to detect blood and calcium in several clinical scenarios such as degenerative joint disease or bone and soft tissue lesion assessment and discriminate between both compounds, something which is not always possible with conventional MRI approaches. In this paper, physical basis and technical adjustment for SWI acquisition at MSK are detailed reviewing the potential application of SWI in different MSK clinical scenarios.

Abstract
Aim: Intussusception, the most common abdominal emergency in early childhood, is frequently misdiagnosed at initial presentation. The effect of using point-of-care ultrasonography (POCUS) by emergency medicine physicians on pediatric intussusception misdiagnosis rate remains unclear. Here, we summarize outcomes and misdiagnoses before and after training junior and senior physicians on using POCUS for diagnosing intussusception and compared their performance levels. Materials and Methods: This observational cohort analysis included patients with suspected intussusception who visited a pediatric emergency department (ED) between January 2017 and December 2019. All enrolled patients were evaluated by junior (<10-year experience) or senior attending physicians. Misdiagnosis was defined as a finding of negative air reduction or confirmation of diagnosis on ED revisit or admission. The misdiagnosis rates and outcomes before and after POCUS training for intussusception diagnosis were evaluated and performance of the junior and senior physicians was compared. Results: Of the 167 enrolled patients, 130 were confirmed to have intussusception by air reduction. Misdiagnosis rate was significantly lower in the post-training patient group after training than in the pre-training patient group (43.7 vs. 12.7%, P < 0.001). After training, fewer misdiagnoses were made by the junior (59.1 vs. 25.9%, P = 0.003) and senior (31.7 vs. 0%, P < 0.001) physicians. In the post-training patient group, the door-to-reduction time and rate of ultrasonography consultation with an expert also decreased significantly (118.2 ± 124.5 vs. 198 ± 250.2 min, P = 0.006). Abdominal pain (80.9%) was the most common symptom of intussusception, followed by vomiting (58.3%), fever (17.8%), bloody stool (15.4%), and diarrhea (14.2%). Even after training, the presenting symptoms of intussusception often leading junior physicians to misdiagnosis were diarrhea and fever. Conclusions: A brief POCUS training leads to decreased misdiagnosis rates in both the senior and junior physicians. Junior physicians should increase their awareness regarding diarrhea and fever being the presenting symptoms of intussusception, particularly in early childhood. Combining clinical judgment and POCUS results forms the core principle of the evaluation of children with intussusception.

Abstract
Study Design: A quasi-experimentalBackground: The talar tilt test and the anterior drawer test are clinically used to evaluate the length of the anterotalofibular (ATFL) and calcaneofibular (CFL) ligaments. Based on the current literature, there is no clear diagnostic utility or preference for either test. This study investigated ligament lengthening during these special tests and compared the talar tilt test to the long axis distraction test for the CFL length.Methods: A convenience sample of 47 healthy subjects were recruited for this study. Musculoskeletal ultrasound imaging (MSK US) was used to measure the length of the ATFL and CFL during the talar tilt and anterior drawer tests. Additionally, CFL lengthening during the talar tilt was compared to the long axis distraction test.Outcomes: A significant difference was found (p < .001) in ATFL length between the talar tilt and anterior drawer test. This indicates that the talar tilt test is preferred to maximally lengthen the ATFL. There was a significant difference in CFL length (p < .001) between the talar tilt test and the long axis distraction test.Discussion: The results of this study identified that the talar tilt test resulted in more ATFL lengthening than the anterior drawer test and thus is the preferred test to assess ligament length. Additionally, both the long axis distraction test and the talar tilt test cause lengthening of the CFL. Therefore, the long axis distraction test can be used as a differentiation test to determine if either the ATFL or the CFL is the structure with increased laxity.

Abstract
Ultrasound (US) assists in the determination of the pathology underlying greater trochanteric pain syndrome (GTPS); however, there exists no consensus regarding the US criteria used to define these pathologies. We aim to explore these US definitions and their associated prevalence. "Trochanteric bursitis" was defined in 10 studies (13 included studies) and was heterogeneously described. "Tendinopathy" was defined in 4 studies, while 7 studies defined "tendinosis." "Tendon tears" were defined in 8 studies, 6 of which distinguished between "partial- and full-thickness tears." Tendon pathology was most frequent in 5 studies (prevalence: 7%-93%), and bursitis in 2 studies (prevalence: 10%-75%); 3 studies had equal distribution. Methodological quality was limited in the descriptions of GTPS and US approaches. Together, we document the lack of standardized US definitions of the pathologies underlying GTPS. This may explain the heterogenous prevalence of US findings. Standardized definitions are needed to improve the reliability of future GTPS studies.

Abstract
BACKGROUND/AND PURPOSE Musculoskeletal ultrasound imaging (MSK US) is an emerging diagnostic tool in physical therapy, which allows for dynamic visualization of tissues in real time. Plantar fasciitis is a common condition causing heel and arch pain and has been related with degenerative changes in the plantar fascia resulting in tissue thickening. Instrument Assisted Soft Tissue Mobilization (IASTM) is an intervention that allows clinicians deep penetration to treat tissues. The mechanical forces caused by IASTM might cause localized tissue trauma leading to stimulation of the body's natural inflammation and healing processes. The purpose of this case report is to demonstrate the use of ultrasound imaging to guide the decision-making process and to discern the optimal location for the application of IASTM. CASE DESCRIPTION The subject was a 46-year-old female yoga practitioner and runner, who presented with right foot pain. The clinical impression was formulated based on the combination of traditional physical therapy examination procedures and MSK US imaging findings of the plantar fascia demonstrating thickness and tendinosis like changes within the plantar fascia 3 cm distally from the calcaneus. OUTCOMES The subject was seen for eight treatment sessions over four weeks, at which time the goals of normal ankle dorsiflexion, no pain with palpation of the plantar fascia, negative windlass test, and no reported pain during gait were achieved. DISCUSSION This case report illustrates the use of MSK US imaging as a method to objectively assess tissue quality and guide decision-making when managing patients with plantar fascia related pain. MSK US was used to determine the optimal location for the application of IASTM during the conservative management of a runner with plantar fasciitis. LEVEL OF EVIDENCE Therapy, Level 5.

Abstract
Aim To develop a standardised ultrasound imaging (USI)-based criteria for the diagnosis of tendinopathy that aligns with the continuum model of tendon pathology. Secondary aims were to assess both the intra-rater and inter-rater reliability of the criteria. Methods A criteria was developed following a face validity assessment and a total of 31 Achilles tendon ultrasound images were analysed. Intra-rater and inter-rater reliability were assessed for overall tendinopathy stage (normal, reactive/early dysrepair or late dysrepair/degenerative) as well as for individual parameters (thickness, echogenicity and vascularity). Quadratic weighted kappa (kw) was used to report on reliability. Results Intra-rater reliability was ‘substantial’ for overall tendinopathy staging (kw rater A; 0.77, 95% CI 0.59 to 0.94, rater B; 0.70, 95% CI 0.52 to 0.89) and ranged from ‘substantial’ to ‘almost perfect’ for thickness (kw rater A; 0.75, 95% CI 0.59 to 0.90, rater B; 0.84, 95% CI 0.71 to 0.98), echogenicity (kw rater A; 0.78, 95% CI 0.62 to 0.95, rater B; 0.73, 95% CI 0.58 to 0.89) and vascularity (kw rater A; 0.86, 95% CI 0.74 to 0.98, rater B; 0.89, 95% CI 0.79 to 0.99). Inter-rater reliability ranged from ‘substantial’ to ‘almost perfect’ for overall tendinopathy staging (kw round 1; 0.75, 95% CI 0.58 to 0.91, round 2; 0.81, 95% CI 0.63 to 0.99), thickness (kw round 1; 0.65, 95% CI 0.48 to 0.83, round 2; 0.77, 95% CI 0.60 to 0.93), echogenicity (kw round 1; 0.70, 95% CI 0.54 to 0.85, round 2; 0.76, 95% CI 0.58 to 0.94) and vascularity (kw round 1; 0.89, 95% CI 0.79 to 0.99, round 2; 0.86, 95% CI 0.74 to 0.98). Inter-rater reliability increased from ‘substantial’ in round 1 (kw 0.75, 95% CI 0.58 to 0.91) to ‘almost perfect’ in round 2 (0.81, 95% CI 0.63 to 0.99). Conclusion Intra-rater and inter-rater reliability were ‘substantial’ to ‘almost perfect’ when utilising an USI-based criteria to diagnose Achilles tendinopathy. This is the first study to use the continuum model of tendon pathology to develop an USI-based criteria to diagnose tendinopathy.

Abstract
OBJECTIVE Musculoskeletal pain is a common complaint among patients with primary Sjogren's syndrome (pSS). Joints clinical examination is oftenly normal. A periarticular origin of this pain may be possible. Since clinical examination lacks sensitivity and precision, the use of musculoskeletal ultrasound (US) is more interesting in the evaluation of the entheses involvement, as it is shown to be a more sensitive tool. Our objective was to assess, by an ultrasonographic study, the entheses involvement in the widespread pain of patients with pSS. METHODS This is a prospective study including 25 women with pSS and 25 age and sex matched healthy controls. An ultrasound examination, using grey scale and Doppler US, of five enthesitic sites (distal quadricipital, proximal patellar, distal patellar, distal Achillian and distal brachial tricipital) sought bilaterally the following lesions: hypoechogenicity, thickening, loss of fibrillar structure, erosions, enthesophytes, calcifications or Doppler hypervascularisation. A final score was calculated by summing the abnormalities scores of all entheses. RESULTS The mean age was 53.2±11.3 years in the pSS group and 50.6±9.7 years in the control group. The mean number of pathological entheses on ultrasound was 3.92±1.93 in the pSS group versus 4.52±2.27 in the control group (P>0.05). The total score for enthesitis abnormalities was 4.96±2.59 versus 5.72±2.92 (P>0.05), respectively. There was a positive correlation between total score of ultrasound enthesitic abnormalities and age in both groups. CONCLUSION In patients with pSS, clinically painful sites were more frequently found than in US. Musculoskeletal pain was not due to enthesitis.

Abstract
Juvenile idiopathic arthritis (JIA) is a heterogeneous group of chronic inflammatory arthritides that if inadequately treated, may be associated with chronic disability and deformity. Early diagnosis and treatment initiation is essential in the management of patients with JIA. Conventional means of evaluation of disease presence, disease activity and response to therapy including physical exam, labs and x-rays are at times limited and may be insufficient in making an accurate assessment. Musculoskeletal ultrasound (MSUS) is a well-established modality that is patient and family-friendly, non-invasive, does not require sedation and can be performed at the bedside in real-time. MSUS offers information that cannot be attained by standard outcome measures, and may help to advance both diagnosis and treatment of patients with JIA ultimately improving patient outcomes. This review explores the background of MSUS and the current evidence to support its potential role as a diagnostic, disease activity monitoring and interventional tool.

Abstract
BACKGROUND Regardless of fibular status, the presence of a superficial deltoid ligament disruption or a combination of deep and superficial deltoid ligament disruption is central to the decision-making process in treating ankle fractures. The aims of the present study were to test whether ultrasonography can assess deltoid ligament integrity and to determine its validity and reliability by comparing it with gravity stress radiography. METHODS A consecutive series of 81 eligible patients with a nondisplaced or minimally displaced fibula fracture identified on a standard radiograph were prospectively enrolled. All patients underwent gravity stress radiography and ultrasonography. Image analysis included the layer type, integrity, and tear site of the deltoid ligament. Ultrasound validity and intra- and interobserver reliability were assessed by the interpretations of the first author and an independent observer who were blinded to the results. RESULTS Of all patients, 64 (79.0%) had a deltoid ligament disruption; most of the tears were of both the superficial and deep layers, partial and proximal attachment tears, and only 8 (12.5%) were complete tears. Patients with an intact deltoid ligament had a mean medial clear space (MCS) value of 2.7 ± 0.5 mm, and those with deltoid ligament tears had a mean MCS value of 5.9 ± 3.4 mm (P < .001). In a comparison between ultrasonography and gravity radiography, we found a sensitivity of 100% versus 97%, a specificity of 90% versus 100%, a positive predictive value of 97% versus 100%, and a negative predictive value of 100% versus 90%, respectively. The intra- and interobserver reliability was evaluated as almost perfect in all conditions. In a comparison between ultrasonography and gravity radiography, we found a sensitivity of 100% versus 97%, a specificity of 90% versus 100%, a positive predictive value of 97% versus 100%, and a negative predictive value of 100% versus 90%, respectively. CONCLUSION Ultrasonography proved to be an accurate tool, allowing the identification of deltoid ligament disruption and the involved components in a more dynamic fashion. Its relative ease of use and lack of ionizing radiation make it a useful and confident technique that can be performed by an orthopedist. LEVEL OF EVIDENCE Level II, prospective comparative study.

Abstract
Background: Clinical decision-making within the physical therapy treatment process typically follows the hypothetical-deductive method. The accuracy and reliability of clinical tests affect this reasoning process. Musculoskeletal ultrasound imaging (MSK US) is an emerging valid and reliable diagnostic tool in physical therapy. MSK US allows for dynamic visualization of tissues in real time with devices that are often portable.Case Description: The patient was a 55-year-old female, who presented by direct access. She had been suffering from cervicogenic headaches since the age of 18. It was hypothesized that this patient presented with a right rotation positional default of atlas and facet hypomobility at C5-6.Outcomes: After six visits (over 7 weeks) of manual therapy interventions, the patient reported that her headaches and neck pain were no longer present. Her physical therapy goals had been met and she was discharged with the instruction to continue working on her posture correction and self-management.Discussion: This case report describes the use of MSK US imaging as part of the clinical decision-making process when treating a patient with cervicogenic headaches. This case illustrates the successful management using manual therapy to restore position, mobility, decrease muscle tone, and normalize upright posture. Complementary research is necessary to further validate MSK US imaging as the preferred method to objectivize joint mobility and guide decision-making. Additionally, the cause-effect relationship between the treatment and positive outcomes in this case report has to be further validated.

Abstract
Objective To determine whether optical spectral transmission (OST) can be used to assess synovitis in hand and wrist joints of patients with hand osteoarthritis (OA). Design Hand and wrist joints of 47 primary hand OA patients with at least one clinically inflamed hand or wrist joint were assessed for synovitis by OST and ultrasound (US). Associations between standardized OST and US synovitis were studied in linear mixed effects models, across all joint types together and individually for wrist, proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints, and were adjusted for OA features that showed associations with US synovitis. Diagnostic performance was determined using receiver operator characteristic (ROC) curves analysis, with US as reference standard. Results Altogether, 6.7% of joints showed US synovitis. Statistically significant associations between OST scores and US synovitis were found for all joints combined (Δ0.37SD, p<0.001) and PIP joints (Δ0.81SD, p<0.001), but not for DIP (Δ0.14SD, p = 0.484) or wrist joints (Δ0.37SD, p = 0.178). All associations were independent of other OA features, i.e. osteophytes and dorsal vascularity. Analysis of diagnostic performance of OST, revealed an area under the ROC curve (AUC-ROC) of 0.74 for all joints together (p<0.001), 0.69 for PIP joints (p<0.001), 0.54 for DIP joints (p = 0.486), and 0.61 for wrist joints (p = 0.234). Conclusions OST scores and US synovitis are statistically significantly associated, independent of osteophytes and dorsal vascularity. At this stage, OST performs fair in the assessment of synovitis in PIP joints of hand OA patients.

Abstract
PURPOSE This study aimed at investigating the prevalence of crystal deposits with knee osteoarthritis (OA) by ultrasonography and measure the inflammatory burden associated with crystal deposits in OA using WOMAC score. METHODS Adult patients with primary knee OA diagnosed according to the American College of Rheumatology criteria were included. Participants were subjected to history taking, clinical examination, knee US, and plain radiography. The EULAR and the OMERACT ultrasonography definitions and scanning protocols were used. RESULTS Fifty-three patients (44 females, 9 males) were enrolled. Mean values were 53.5 years ± 8.3 SD for age and 42.5 months ± 49.5 SD for disease duration. Crystals were detected by US in 73/106 knees (68.9%). Plain radiography revealed chondrocalcinosis in three patients. Mean values for WOMAC pain, stiffness, and disability scores were 14.38 ± 3.99, 4.93 ± 2.06, and 49.61 ± 13.06, respectively, with insignificant differences relative to presence of crystals (P > 0.05). Regression analysis revealed a 4.1-fold increase in the incidence of sonographic crystals with bursitis (OR = 4.13, CI = 1.5-11.2, p = 0.01) and a 3.2-fold increase in the incidence of sonographic crystals with synovial effusion (OR = 3.16, CI = 1.34-7.44, p = 0.01). CONCLUSION Subclinical crystals were detected in a considerable number of patients with primary knee OA. The incidence of crystal deposits was significantly higher in patients with bursitis and knee effusion.

Abstract
Background The detection of joint swelling caused by synovitis is important for the diagnosis of inflammatory arthritis. Ultrasound (US) and MRI have proven to be more sensitive and reliable than physical examination, but they are time-consuming and expensive. The automated breast volume scanner was developed to acquire serial B-mode pictures of the female breast and these can be analyzed in all three dimensions. Objectives To analyze the value of automated B-mode ultrasound employing the ABVS system in detecting synovitis of the finger joints compared to manual ultrasound (mUS) and physical examination, using MRI as the gold standard. Methods 19 consecutive patients suffering from active rheumatoid (n=15) or psoriatic (n=4) arthritis were included. Automated and mUS were conducted with a linear array (ACUSON S2000™, 11 MHz). Multiplanar reconstruction enabled examination of the images for the presence of synovitis. Results 90% of the hand joints were assessable by automated ultrasound. Automated US detected 12.0, mUS 14.2, MRI 13.4, and clinical examination 4.1 positive joints - i. e. joints with synovitis - on average per patient. The inter-observer reliability of both assessors for automated and mUS, MRI, and physical examination, was 66.9%, 72.7%, 95.1%, and 88.9%, respectively. 84.3% of the joints classified as positive on MRI were confirmed by automated ultrasound, 85.5% on mUS, and 36.0 on physical examination. This translated into a sensitivity of 83.5%, 85.5%, and 36.0% for the three methods, respectively. Conclusion: Automated ultrasound is a promising ultrasound method for assessing small joints in patients with inflammatory arthritis.

Abstract
With the introduction of new biologics such as anti-TNF-alpha antibodies and other therapies in the treatment of inflammatory arthritis, capable of halting joint destruction and functional disability, there are new pressures on diagnostic and prognostic imaging. Early demonstration of pre-erosive inflammatory features and monitoring of the long-term effects of treatment are becoming increasingly important. Early detection of synovitis offers advantages in terms of allowing early instigation of therapy and may allow the identification of those patients displaying more aggressive disease who might benefit from early intervention with expensive DMARD therapy. Advanced imaging techniques such as ultrasound (US) and magnetic resonance imaging (MRI) have focussed on the demonstration and quantification of synovitis and allow early diagnosis of inflammatory arthropathies such as rheumatoid arthritis (RA) and psoriatic arthritis (PsA). Synovitis represents a potential surrogate measure of disease activity that can be monitored using either MRI or US; the techniques have, generally, focused on monitoring synovial volume or quality as assessed by its vascularity. However to achieve these goals, standardisation and validation of US and MRI are required to ensure accurate diagnosis, reproducibility and reliability. Each modality has different strengths and weaknesses and levels of validation. This article aims to increase the awareness of radiologists and rheumatologists about this field and to encourage them to participate and contribute to the ongoing development of these modalities. Without this collaboration, it is unlikely that these modalities will reach their full potential in the field of rheumatological imaging. This review is in two parts. The first part addresses the role of US and colour or power Doppler sonography (PDUS) in the detection and monitoring of synovitis in inflammatory arthropathies. The second part will look at advanced MR imaging and Dynamic contrast-enhanced MRI techniques and in particular how they are applied to the monitoring of the disease process.

Abstract
Objectives Although RA patients achieve clinical remission, risk of flare still exists. Given the association between US synovitis and increased risk of flare, it is of clinical interest whether these patients report a different health status. Therefore, our aim was to evaluate the frequency of US remission in RA patients in clinical remission and to compare the health status of RA patients in clinical remission with those who were also in US remission. Methods In a prospective study, we included 89 RA patients (aged >17 years) treated with a synthetic DMARD and a TNF inhibitor who were in remission (DAS in 44 joints ⩽2.4 and swollen joint count ⩽1). Demographic characteristics, swollen and tender joints, laboratory variables, US (MCP2-5, PIP2-5, wrists and MTP2-5) and patient-reported outcomes (general health, functional ability, fatigue, depression and anxiety, pain and morning stiffness) were recorded at two consecutive visits (3 months apart). US remission was defined as grey scale grade ⩽1 and power Doppler = 0. Results At visit 1, 39% of patients were in US remission. At visit 2, 32% of patients were in US remission. At visit 1, functional ability (HAQ) was scored lower by patients in US remission (P = 0.029). At visit 2, HAQ scores were similar (P = 0.928). At visit 2, Hospital Anxiety and Depression Scale anxiety score and visual analog scale pain were significantly higher in patients in US remission. Similar levels were found for the other patient-reported outcomes. Conclusion One-third of RA patients in clinical remission were in US remission. In our study population, we could not find a clear association between health status of RA patients and being in US remission.

Abstract
BACKGROUND To decrease the burden of disease of rheumatoid arthritis (RA), patients at risk for RA need to be identified as early as possible, preferably when no clinically apparent synovitis can be detected. Up to now, it has been fairly difficult to identify those patients with arthralgia who develop inflammatory arthritis (IA), but recent studies using ultrasound (US) suggest that earlier detection is possible. We aimed to identify patients with arthralgia developing IA within 1 year using US to detect subclinical synovitis at first consultation. METHODS In a multi-centre cohort study, we followed patients with arthralgia with at least two painful joints of the hands, feet or shoulders without clinical synovitis over 1 year. Symptom duration was < 1 year, and symptoms were not explained by other conditions. At baseline and at 6 and 12 months, data were collected for physical examinations, laboratory values and diagnoses. At baseline, we examined 26 joints ultrasonographically (bilateral metacarpophalangeal joints 2-5, proximal interphalangeal joints 2-5, wrist and metatarsophalangeal joints 2-5). Scoring was done semi-quantitatively on greyscale (GS; 0-3) and power Doppler (PD; 0-3) images. US synovitis was defined as GS ≥ 2 and/or PD ≥ 1. IA was defined as clinical soft tissue swelling. Sensitivity and specificity were used to assess the diagnostic value of US for the development of IA. Univariate logistic regression was used to analyse the association between independent variables and the incidence of IA. For multivariate logistic regression, the strongest variables (p < 0.157) were selected. Missing values for independent variables were imputed. RESULTS A total of 196 patients were included, and 159 completed 12 months of follow-up. Thirty-one (16%) patients developed IA, of whom 59% showed US synovitis at baseline. The sensitivity and specificity of US synovitis were 59% and 68%, respectively. If no joints were positive on US, negative predictive value was 89%. In the multivariate logistic regression, age (OR 1.1), the presence of morning stiffness for > 30 minutes (OR 3.3) and PD signal (OR 3.4) were associated with incident IA. CONCLUSIONS The presence of PD signal, morning stiffness for > 30 minutes and age at baseline were independently associated with the development of IA. Regarding the value of US in the diagnostic workup of patients with early arthralgia at risk for IA, US did perform well in ruling out IA in patients who did not have US synovitis.

Abstract
OBJECTIVE The aim of this study was to evaluate the diagnostic agreement when a general practitioner and subsequently a specialist (radiologist/gynecologist) performed point-of-care ultrasound examinations for certain abdominal and gynecological conditions of low to moderate complexity. DESIGN A prospective study of inter-rater reliability and agreement. SETTING Patients were recruited and initially scanned in general practice. The validation examinations were conducted in a hospital setting. SUBJECTS A convenient sample of 114 patients presenting with abdominal pain or discomfort, possible pregnancy or known risk factors toward abdominal aortic aneurism were included. MAIN OUTCOME MEASURES Inter-rater agreement (Kappa statistic and percentage agreement) between ultrasound examinations by general practitioner and specialist for the following conditions: gallstones, ascites, abdominal aorta >5 cm, intrauterine pregnancy and gestational age. RESULTS An overall Kappa value of 0.93 (95% confidence interval (CI): 0.87-0.98) was obtained. Ascites, abdominal aortic diameter >5cm, and intrauterine pregnancy showed Kappa values of 1. CONCLUSION Our study showed that general practitioners performing point-of-care ultrasound examinations with low-to-moderate complexity had a very high rate of inter-rater agreement compared with specialists.

Abstract
[Purpose] The purpose of this study was to assess intra-rater and inter-rater reliability of musculoskeletal ultrasound (MSKUS) as a tool to measure supraspinatus tendon thickness in healthy subjects. [Subjects and Methods] Twenty healthy subjects were assessed in similar sitting position. Two experienced musculoskeletal ultrasound specialists measured supraspinatus tendon thickness. Tendon was measured twice in one day by each of two raters with an interval of one hour for within day reliability and was re-measured following one week for between days reliability. Data analysis was performed using the intraclass correlation coefficient (ICC) and standard error of measurement (SEM). [Results] Results reflected excellent within day intra-rater and inter-rater reliability with Mean ± standard deviation (SD)=5.14 ± 0.83 and 5.17 ± 0.78, ICC (2,1)=0.89-0.93 and ICC (2,2)=0.98 (0.95-0.99) and SEM=0.18-0.18 and 0.17 while between days intra-rater rater and inter-rater reliability with Mean ± SD=5.14 ± 0.83 and 5.17 ± 0.78, ICC(2,1)=0.88-0.90 and ICC(2,2)=0.95 (0.88-0.98), SEM=0.17-0.38 and 0.17 [Conclusion] The results of the current study indicate that MSKUS is a reliable tool for measuring supraspinatus tendon thickness in healthy subjects.

Abstract
Ultrasound has become popular among rheumatologists as the first-choice imaging investigation for the evaluation and monitoring of osteoarthritis (OA). Because of recent improvement in technology, ultrasound has the ability to demonstrate and assess the minimal structural abnormalities, which involve the pathophysiology and progression of OA, such as articular cartilage, synovial tissue, bony cortex, and other soft tissue. Nowadays, ultrasonography is a promising technique for assessing soft tissue abnormalities such as joint effusion, synovial hypertrophy, Baker cyst, and other structural changes including the decrease in cartilage thickness, meniscus bulging, and formation of osteophyte. Ultrasonography not only possesses diagnostic potential in knee OA but also reveals long-term predictability for disease progress as imaging biomarker. Ultrasonography has also been proven as a useful tool in guiding therapeutic interventions and monitoring treatment effectiveness. This review addresses the utility, reliability, and potential utilization of ultrasonography as an imaging technique in knee OA.

Abstract
BACKGROUND Limited quantitative, physiological evidence exists regarding the effectiveness of Kinesio® Taping methods, particularly with respect to the potential ability to impact underlying physiological joint space and structures. To better understand the impact of these techniques, the underlying physiological processes must be investigated in addition to the examination of more subjective measures related to pain in unhealthy tissues. HYPOTHESIS/PURPOSE The purpose of this study was to determine whether the Kinesio® Taping Space Correction Method created a significant difference in patellofemoral joint space, as quantified by diagnostic ultrasound. STUDY DESIGN Pre-test/post-test prospective cohort study. METHODS Thirty-two participants with bilaterally healthy knees and no past history of surgery took part in the study. For each participant, diagnostic ultrasound was utilized to collect three measurements: the patellofemoral joint space, the distance from the skin to the superficial patella, and distance from the skin to the patellar tendon. The Kinesio® Taping Space Correction Method was then applied. After a ten-minute waiting period in a non-weight bearing position, all three measurements were repeated. Each participant served as his or her own control. RESULTS Paired t tests showed a statistically significant difference (mean difference = 1.1 mm, t[3,1] = 2.823, p = 0.008, g = .465) between baseline and taped conditions in the space between the posterior surface of the patella to the medial femoral condyle. Neither the distance from the skin to the superficial patella nor the distance from the skin to the patellar tendon increased to a statistically significant degree. CONCLUSIONS The application of the Kinesio® Taping Space Correction Method increases the patellofemoral joint space in healthy adults by increasing the distance between the patella and the medial femoral condyle, though it does not increase the distance from the skin to the superficial patella nor to the patellar tendon.

Abstract
Background Three-dimensional (3D) ultrasound of the shoulder is characterized by a comparable accuracy to two-dimensional (2D) ultrasound. No studies investigating 2D versus 3D inter-rater reliability in the detection of supraspinatus tendon tears taking into account the level of experience of the raters have been carried out so far. Objectives The aim of this study was to determine the inter-rater reliability in the analysis of 3D ultrasound image sets of the supraspinatus tendon between sonographer with different levels of experience. Patients and methods Non-interventional, prospective, observational pilot study of 2309 images of 127 adult patients suffering from unilateral shoulder pain. 3D ultrasound image sets were scored by three raters independently. The intra-and interrater reliabilities were calculated. Results There was an excellent intra-rater reliability of rater A in the overall classification of supraspinatus tendon tears (2D vs 3D κ = 0.892, pairwise reliability 93.81%, 3D scoring round 1 vs 3D scoring round 2 κ = 0.875, pairwise reliability 92.857%). The inter-rater reliability was only moderate compared to rater B on 3D (κ = 0.497, pairwise reliability 70.95%) and fair compared to rater C (κ = 0.238, pairwise reliability 42.38%). Conclusions The reliability of 3D ultrasound of the supraspinatus tendon depends on the level of experience of the sonographer. Experience in 2D ultrasound does not seem to be sufficient for the analysis of 3D ultrasound imaging sets. Therefore, for a 3D ultrasound analysis new diagnostic criteria have to be established and taught even to experienced 2D sonographers to improve reproducibility.

Abstract
Background: Arthrosonography has proven to be more sensitive and reliable for the detection of synovitis than clinical examination, but a comprehensive examination of small joints is time-consuming. The automated breast volume scanner (ABVS) has been developed to allow automatic and reproducible series of consecutive B-mode pictures of the female breast. Objectives: To analyze the comparability of ABVS and conventional manual ultrasonography (mUS) for the detection of synovitis in hands and feet of patients with rheumatoid arthritis (RA). Methods: 45 patients with early and established active rheumatoid arthritis were recruited for this trial. All subjects were assessed clinically and by manual (Esaote MyLab70) and automated ultrasound (ACUSON S2000™ ABVS). The wrists, the metacarpophalangeal and proximal interphalangeal joints of the hands and the metatarsophalangeal joints of the feet were examined. Results: A total of 2 340 joint aspects were examined with both methods. ABVS detected 291 grade 1, 124 grade 2, 100 grade 3 cases of synovitis (515 in total) compared to 267, 180 and 145 cases of synovitis (592 in total) with mUS. 242 erosions and 52 cases of tenosynovitis were found by ABVS compared to 244 erosions and 99 cases of tenosynovitis found by mUS. Kappa coefficients for the agreement between both methods ranged from 0.51 in PIP joints to 0.71 in MCP joints. The correlations with clinical parameters as well as interrater agreements were comparable for both ultrasound methods. Conclusion: Based on the results, ABVS seems to be a promising technology for the comprehensive and time-saving assessment of synovitis in RA.

Abstract
AIM To evaluate the inter-rater reliability of measuring structural changes in the tendon of patients, clinically diagnosed with supraspinatus tendinopathy (cases) and healthy participants (controls), on ultrasound (US) images captured by standardised procedures. METHODS A total of 40 participants (24 patients) were included for assessing inter-rater reliability of measurements of fibrillar disruption, neovascularity, as well as the number and total length of calcifications and tendon thickness. Linear weighted κ, intraclass correlation (ICC), SEM, limits of agreement (LOA) and minimal detectable change (MDC) were used to evaluate reliability. RESULTS 'Moderate-almost perfect' κ was found for grading fibrillar disruption, neovascularity and number of calcifications (k 0.60-0.96). For total length of calcifications and tendon thickness, ICC was 'excellent' (0.85-0.90), with SEM(Agreement) ranging from 0.63 to 2.94 mm and MDC(group) ranging from 0.28 to 1.29 mm. In general, SEM, LOA and MDC showed larger variation for calcifications than for tendon thickness. CONCLUSIONS Inter-rater reliability was moderate to almost perfect when a standardised procedure was applied for measuring structural changes on captured US images and movie sequences of relevance for patients with supraspinatus tendinopathy. Future studies should test intra-rater and inter-rater reliability of the method in vivo for use in clinical practice, in addition to validation against a gold standard, such as MRI.

PURPOSE Rotator cuff (RC) tendinopathy has been widely ascribed to impingement of the supraspinatus tendon (SsT) in the subacromial space, measured as the acromiohumeral distance (AHD). Ultrasound (US) is suitable for measuring AHD and SsT thickness, but few reliability studies have been carried out in symptomatic populations, and interrater reliability is unconfirmed. This study aimed to examine the intrarater and interrater reliability of US measurements of AHD and SsT thickness in asymptomatic control subjects and patients with RC tendinopathy. METHODS Seventy participants were recruited and grouped as healthy controls (n = 25) and RC tendinopathy (n = 45). Repeated US measurements of AHD and SsT thickness were obtained by one rater in both groups and by two raters in the RC tendinopathy group. RESULTS Intrarater and interrater reliability coefficients were excellent for both measurements (intraclass correlation > 0.92), but the intrarater reliability was superior. The minimal detectable change values in the symptomatic group were 0.7 mm for AHD and 0.6 mm for SsT thickness for a single experienced examiner; the values rose to 1.2 mm and 1.3 mm, respectively, for the pair of examiners. CONCLUSIONS The results support the reliability of US for the measurement of AHD and SsT thickness in patients with symptomatic RC tendinopathy and provide minimal detectable change values for use in future research studies.

Abstract
Musculoskeletal ultrasound (MSUS) training is now a required component of physiatry residency, but formal curriculum guidelines are not yet required or established. The authors' objective was to assess the educational value of a collaborative residency MSUS training program. The authors designed a structured MSUS training curriculum for residents based on the authors' experience and previous literature. Twenty-five residents participated in this MSUS curriculum designed by faculty and chief residents. Resident volunteers were trained by the faculty as "table trainers" who taught their peers in small groups. Hands-on MSUS training sessions were led by a Physical Medicine and Rehabilitation faculty MSUS expert. A Likert scale-formatted questionnaire assessed resident-perceived value of the curriculum. Response rate was 96% (22 of 23). Self-reported MSUS knowledge comparing precurriculum and postcurriculum implementation resulted in significant improvement (P = 0.001). Peer teaching was highly valued, with 86% of residents rating it "very" or "extremely" beneficial (mean [SD] score, 3.9 [1.1]). Self-guided learning, by supplemental scanning and reading, was rated "beneficial" or "very beneficial" by 73% of residents (3.0 [0.7]). The authors' successful pilot program may serve as a teaching model for other residency programs.

JOURNAL OF RESEARCH IN MEDICAL SCIENCES 2016; 21:134. [PMID: 28331520 PMCID: PMC5348830 DOI: 10.4103/1735-1995.196616] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2016] [Revised: 08/08/2016] [Accepted: 09/07/2016] [Indexed: 11/08/2022]
Abstract
Background: This study aimed to compare the percentage of detection of periarthritis in patients with rheumatoid arthritis using clinical examination and ultrasound methods. Materials and Methods: This study is a cross-sectional study which was conducted in Al-Zahra Hospital (Isfahan, Iran) during 2014–2015. In our study, ninety patients were selected based on the American College of Rheumatology 2010 criteria. All patients were examined by a rheumatologist to find the existence of effusion, and the data were filled in the checklist. The ultrasonography for detecting effusion in periarticular structures was done by an expert radiologist with two methods, including high-resolution ultrasonography and power Doppler. The percentage of effusion existence found by physical examination was compared by sonography, and the Chi-square and t-tests were used for data analysis. Results: The percentage of effusion found in areas with physical examination by rheumatologist was lower than the frequency distribution of effusions found by sonography (8.3% VS 14.2%) (P < 0.001). In sonography, rotator cuff tendonitis is the most common periarthritis. Other findings in sonography were biceps tendinitis (10 cases), wrist tendonitis (13 cases), olecranon bursitis (9 cases), golfers elbow (4 cases), tennis elbow (4 cases), trochanteric bursitis (6 cases), anserine bursitis (6 cases), prepatellar bursitis (11 cases), and ankle tendonitis (7 cases). Tenderness on physical examination was found in 15% of the cases, and the evidence of periarthritis was found in 21/7% through sonography (P < 0.001) and 34% through Doppler sonography (P < 0.001). Conclusion: The percentage of periarthritis detection by ultrasonography and power Doppler sonography was higher than clinical examination. Hence, the ultrasonography is more accurate than physical examination.

Abstract
Objective High resolution ultrasonography is a non-painful and non-invasive imaging technique which is useful for the assessment of shoulder pain causes, as clinical examination often does not allow an exact diagnosis. The aim of this study was to compare the findings of clinical examination and high resolution ultrasonography in patients presenting with painful shoulder. Methods Non-interventional observational study of 100 adult patients suffering from unilateral shoulder pain. Exclusion criteria were shoulder fractures, prior shoulder joint surgery and shoulder injections in the past month. The physicians performing the most common clinical shoulder examinations were blinded to the results of the high resolution ultrasonography and vice versa. Results In order to detect pathology of the m. supraspinatus tendon, the Hawkins and Kennedy impingement test showed the highest sensitivity (0.86) whereas the Jobe supraspinatus test showed the highest specificity (0.55). To identify m. subscapularis tendon pathology the Gerber lift off test showed a sensitivity of 1, whereas the belly press test showed the higher specificity (0.72). The infraspinatus test showed a high sensitivity (0.90) and specificity (0.74). All AC tests (painful arc IIa, AC joint tendernessb, cross body adduction stress testc) showed high specificities (a0.96, b0.99, c0.96). Evaluating the long biceps tendon, the palm up test showed the highest sensitivity (0.47) and the Yergason test the highest specificity (0.88). Conclusion Knowledge of sensitivity and specificity of various clinical tests is important for the interpretation of clinical examination test results. High resolution ultrasonography is needed in most cases to establish a clear diagnosis.

Abstract
OBJECTIVE To test the reliability of the consensus-based ultrasound (US) definitions of elementary gout lesions in patients. METHODS Eight patients with microscopically proven gout were evaluated by 16 sonographers for signs of double contour (DC), aggregates, erosions, and tophi in the first metatarsophalangeal joint and the knee bilaterally. The patients were examined twice using B-mode US to test agreement and inter- and intraobserver reliability of the elementary components. RESULTS The prevalence of the lesions were DC 52.8%, tophus 61.1%, aggregates 29.8%, and erosions 32.4%. The intraobserver reliability was good for all lesions except DC, where it was moderate. The best reliability per lesion was seen for tophus (κ 0.73, 95% CI 0.61-0.85) and lowest for DC (κ 0.53, 95% CI 0.38-0.67). The interobserver reliability was good for tophus and erosions, but fair to moderate for aggregates and DC, respectively. The best reliability was seen for erosions (κ 0.74, 95% CI 0.65-0.81) and lowest for aggregates (κ 0.21, 95% CI 0.04-0.37). CONCLUSION This is the first step to test consensus-based US definitions on elementary lesions in patients with gout. High intraobserver reliability was found when applying the definition in patients on all elementary lesions while interobserver reliability was moderate to low. Further studies are needed to improve the interobserver reliability, particularly for DC and aggregates.

Abstract
PURPOSE To evaluate the diagnostic performance of susceptibility-weighted imaging (SWI) and standard shoulder joint magnetic resonance (MR) sequences in comparison to that of conventional radiography for the identification of calcifications in the rotator cuff in patients with calcific tendonitis. MATERIALS AND METHODS The institutional review board approved this prospective study. Written informed consent was obtained from all subjects. Fifty-four patients clinically suspected of having calcific tendonitis of the rotator cuff were included. On radiographs (the standard of reference), 27 patients had positive calcification findings, and 27 did not. Standard MR sequences and SWI, including magnitude and phase imaging, were performed. The diameter of calcifications was measured to assess intermodality correlations. Sensitivity, specificity, and intra- and interobserver agreement were calculated. Phantom measurements were performed to assess the detection limit of SWI. RESULTS Fifty-six calcifications were detected with radiography in 27 patients. Most (55 calcifications, 98%) could be identified as calcifications by using SWI. Standard T1- and T2-weighted sequences were used to identify 33 calcifications (59%). SWI yielded a sensitivity of 98% (95% confidence interval [CI]: 0.943, 1) and specificity of 96% (95% CI: 0.886, 1) for the identification of calcifications when compared with radiography. Standard rotator cuff MR sequences yielded a sensitivity of 59% (95% CI: 0.422, 0.758) and specificity of 67% (95% CI: 0.493, 0.847). Diameter measurements demonstrated a high correlation between SWI and radiography (R(2) = 0.90), with overestimation of lesion diameter at SWI (mean ± standard deviation for SWI, 7.6 mm ± 5.4; for radiography, 5.3 mm ± 5.1). SWI yielded higher interobserver agreement (R(2) = 0.99, P < .001; 95% CI: 0.989, 0.996) compared with standard MR sequences (R(2) = 0.67, P = .62; 95% CI: 0.703, 0.899). In phantom experiments, SWI and computed tomography were used to identify small calcifications that were missed at radiography. CONCLUSION SWI enables the reliable detection of calcifications in the rotator cuff in patients with calcific tendonitis by using conventional radiography as a reference and offers better sensitivity and specificity than standard rotator cuff MR sequences.

Abstract
Structural damage in rheumatoid arthritis (RA) occurs early if inflammation is not treated promptly. Treatment targeted to reduce inflammation, in particular, that of synovial inflammation in the joints (synovitis), has been recommended as standard treat-to-target recommendations by rheumatologists. The goal is to achieve disease remission (i.e., no disease activity). Several accepted remission criteria have not always equated to the complete absence of true inflammation. Over the last decade, musculoskeletal ultrasonography has been demonstrated to detect subclinical synovitis not appreciated by routine clinical or laboratory assessments, with the Power Doppler modality allowing clinicians to more readily appreciate true inflammation. Thus, targeting therapy to Power Doppler activity may provide superior outcomes compared with treating to clinical targets alone, making it an attractive marker of disease activity in RA. However, more validation on its true benefits such as its benefits to patients in regard to patient related outcomes and issues with standardized training in acquisition and interpretation of power Doppler findings are required.

Abstract
OBJECTIVES The primary aim of this study was to assess the ultrasonographic features of hip joints in patients with mucopolysaccharidosis (MPS) type I and II in comparison with healthy population. The secondary aims were to correlate these features with clinical measures and to evaluate the utility of ultrasound in the diagnosis of MPS disease. MATERIALS AND METHODS Sixteen MPS I (n = 3) and II (n = 13) patients were enrolled in the present study and underwent clinical and radiological evaluation, and bilateral high-resolution ultrasonography (US) of hip joints. The distance from the femoral neck to joint capsule (synovial joint space, SJS), joint effusion, synovial hyperthrophy, and local pathological vascularization were evaluated. The results were compared to the healthy population and correlated with clinical and radiological measures. RESULTS 1. There was a difference in US SJS between children with MPS disease and the normative value for healthy population (7mm). Mean values of SJS were 15.81 ± 4.08 cm (right hip joints) and 15.69 ± 4.19 cm (left joints). 2. No inflammatory joint abnormalities were detected in MPS patients. 3. There was a clear correlation between US SJS and patients' age and height, while no clear correlation was observed between SJS and disease severity. CONCLUSIONS 1. Patients with MPS I and II present specific features in hip joint ultrasonography. 2. The data suggests that ultrasonography might be effective in the evaluation of hip joint involvement in patients with MPS and might present a valuable tool in facilitating the diagnosis and follow up of the disease.

Abstract
Musculoskeletal ultrasound (US) now thrives as an established imaging modality for the investigation and management of chronic inflammatory arthritis. We summarize here results of the Outcome Measures in Rheumatology (OMERACT) US working group (WG) projects of the last 2 years. These results were reported at the OMERACT 12 meeting at the plenary session and discussed during breakout sessions. Topics included standardization of US use in rheumatic disease over the last decade and its contribution to understanding musculoskeletal diseases. This is the first update report of WG activities in validating US as an outcome measure in musculoskeletal inflammatory and degenerative diseases, including pediatric arthritis, since the OMERACT 11 meeting.

Abstract
Introduction Analyses of large clinical datasets from early arthritis cohorts permit the development of algorithms that may be used for outcome prediction in individual patients. The value added by routine use of musculoskeletal ultrasound (MSUS) in an early arthritis setting, as a component of such predictive algorithms, remains to be determined. Methods The authors undertook a retrospective analysis of a large, true-to-life, observational inception cohort of early arthritis patients in Newcastle upon Tyne, UK, which included patients with inflammatory arthralgia but no clinically swollen joints. A pragmatic, 10-minute MSUS assessment protocol was developed, and applied to each of these patients at baseline. Logistic regression was used to develop two "risk metrics" that predicted the development of a persistent inflammatory arthritis (PIA), with or without the inclusion of MSUS parameters. Results A total of 379 enrolled patients were assigned definitive diagnoses after ≥12 months follow-up (median 28 months), of whom 162 (42%) developed a persistent inflammatory arthritis. A risk metric derived from 12 baseline clinical and serological parameters alone had an excellent discriminatory utility with respect to an outcome of PIA (area under receiver operator characteristic (ROC) curve 0.91; 95% CI 0.88 to 0.94). The discriminatory utility of a similar metric, which incorporated MSUS parameters, was not significantly superior (area under ROC curve 0.91; 95% CI 0.89 to 0.94). Neither did this approach identify an added value of MSUS over the use of routine clinical parameters in an algorithm for discriminating PIA patients whose outcome diagnosis was rheumatoid arthritis (RA). Conclusions MSUS use as a routine component of assessment in an early arthritis clinic did not add substantial discriminatory value to a risk metric for predicting PIA.

Abstract
Carpal tunnel syndrome (CTS) may be caused by subclinical tenosynovitis which may be detected by ultrasonography (US). The objective of this study is to investigate whether ultrasonography has a place in the workup of idiopathic CTS patients. Therefore, we investigated the prevalence of tenosynovitis and its association with the clinical outcome of surgery. A cohort of 31 consecutive idiopathic CTS patients (33 wrists) who were a candidate for carpal tunnel release (CTR) surgery was assessed using greyscale ultrasonography (GSUS) and power Doppler ultrasonography (PDUS). Peroperatively, tenosynovitis was evaluated macroscopically by the surgeon. Tissue samples from areas macroscopically suspected for tenosynovitis were taken for histological evaluation. The clinical outcome of the operation was assessed after 6 months and if applicable alternative diagnoses for the CTS were proposed. US tenosynovitis (OMERACT) was detected preoperatively in 58 % of the wrists. Peroperatively, macroscopic tenosynovitis was detected visually in 88 % of the wrists. Histological evaluation demonstrated a limited influx of lymphocytes indicative of a mild chronic inflammatory response in 19 %. Non-specific reactive changes were observed in 78 % of the cases. Ultrasonographically defined tenosynovitis was associated with an OR of 2.81 (95 % CI 0.61-13) for responding well to surgery. Most cases of ultrasonographic and peroperatively defined tenosynovitis were classified by histology as reactive changes. The presence of ultrasonographic tenosynovitis might be associated with a better clinical outcome of surgery.

Diagnostic value of clinical tests for degenerative rotator cuff disease in medical practice. Ann Phys Rehabil Med 2014; 57:228-43.

Abstract
OBJECTIVES To assess the diagnostic value of clinical tests for degenerative rotator cuff disease (DRCD) in medical practice. METHODS Patients with DRCD were prospectively included. Eleven clinical tests of the rotator cuff have been done. One radiologist performed ultrasonography (US) of the shoulder. Results of US were expressed as normal tendon, tendinopathy or full-thickness tear (the reference). For each clinical test and each US criteria, sensitivity, specificity, negative predictive value and positive predictive value, accuracy, negative likelihood ratio (NLR) and positive likelihood ratio (PLR) were calculated. Clinical relevance was defined as PLR ≥2 and NLR ≤0.5. RESULTS For 35 patients (39 shoulders), Jobe (PLR: 2.08, NLR: 0.31) and full-can (2, 0.5) test results were relevant for diagnosis of supraspinatus tears and resisted lateral rotation (2.42, 0.5) for infraspinatus tears, with weakness as response criteria. The lift-off test (8.50, 0.27) was relevant for subscapularis tears with lag sign as response criteria. Yergason's test (3.7, 0.41) was relevant for tendinopathy of the long head of the biceps with pain as a response criterion. There was no relevant clinical test for diagnosis of tendinopathy of supraspinatus, infraspinatus or subscapularis. CONCLUSIONS Five of 11 clinical tests were relevant for degenerative rotator cuff disease.
