RESUMO
PURPOSE: Adhesive Capsulitis (AC) is a musculoskeletal disorder initially described by Codman in 1934. The disease is characterized by pain-limited restriction in active and passive glenohumeral range of motion (ROM) despite the lack of a structural deficit. In the last decades, arthroscopy and magnetic resonance imaging (MRI) has been the only diagnostic tools able to highlight the characteristic alterations of the glenohumeral capsular-ligament apparatus in AC; nevertheless, both arthroscopy and MRI are burdened by intrinsic limitations. The aim of this narrative review is to summarize the most significant evidence supporting the use of ultrasound (US) for the diagnosis of AC. METHODS: We extensively searched via PubMed library the terms "frozen-shoulder" and "adhesive capsulitis" each combined with "ultrasound". RESULTS: We found 3723 papers on PubMed and selected those inherent to AC diagnosis, US imaging, correlation with arthroscopic and MRI findings. Forty papers which were strictly related to the topic of this narrative review were initially chosen, then 20 studies which described and exploited US for AC diagnosis were finally included. Coracohumeral ligament (2.65 ± 0.4 mm) and axillary pouch thickening (3.34 ± 0.8 mm), as well as an increase in vascularity at rotator interval (78/214, 36.44%), represented the commonest US signs useful for AC diagnosis and for which the most significant cut-off values were reported. CONCLUSIONS: The evidence collected in this review testify that musculoskeletal US is as reliable as MRI for AC diagnosis, therefore we believe that in this context US should be considered a first-line imaging technique.

OBJECTIVE: To study the usefulness of ultrasonography (US) in predicting the diagnostic outcome in patients with polymyalgic symptoms. METHODS: Sixty-one elderly patients with polymyalgic syndrome were recruited in a secondary care setting and followed up in a prospective way. Clinical, laboratory, and US data obtained at onset were re-evaluated after 1 year when diagnostic outcome was defined. RESULTS: A diagnostic shift was observed in 32 polymyalgic patients (52%). Calcium pyrophosphate deposition disease (CPDD) was diagnosed in nine patients, elderly-onset rheumatoid arthritis (EORA) in 18, and elderly-onset spondyloarthritis (EOSpA) in five. In polymyalgia rheumatica (PMR) patients US demonstrated synovitis in 90% of cases, in both proximal (90%) and peripheral joints (41%). The best predictive US model for the definitive diagnosis of PMR comprised: the presence of subacromial-subdeltoid bursitis [odds ratio (OR) 5.603, p = 0.003], low frequency of wrist (OR 0.074, p < 0.001), metacarpophalangeal (OR 0.052, p < 0.001), and metatarsophalangeal effusion/synovitis (OR 0.107, p < 0.027), low frequency of knee menisci chondrocalcinosis (OR 0.091, p = 0.013), tendinous calcaneal calcifications (OR 0.078, p = 0.006), and Achilles enthesitis (OR 0.107, p = 0.027), and low power Doppler US (PDUS) scores at wrist (OR 0.052, p < 0.001). CONCLUSIONS: US and PDUS can be useful in distinguishing, at onset of disease, pure PMR from other diseases mimicking this condition.

INTRODUCTION: The aim of this study was to evaluate the role of bedside ultrasonography (US) in early diagnosis of musculoskeletal complications (MSC) of acquired brain injuries, to describe its incidence and US features in a neurorehabilitation setting. MATERIALS AND METHODS: All 163 patients admitted in tertiary-level neurorehabilitation unit with diagnosis of stroke or severe brain injury (SBI), with symptoms or signs of musculoskeletal pathology, underwent bedside US. RESULTS: MSC were diagnosed in 51.5%. In 86.9% US clarified diagnosis and/or modified therapeutic approach. Shoulder pain was observed in 27.6%. US showed a shoulder subluxation in 73.3% and a frozen shoulder in 8.8% of painful shoulders. In all the cases rotator cuff abnormalities were noted. Wrist-hand syndrome was observed in 29.4%. US showed mild effusion in wrist joints and tendon sheaths and subcutaneous edema without significant vascularity. Neurogenic heterotopic ossification was observed in 1.8%. US demonstrated the "zone phenomenon" or heterogeneously hypoechoic mass with low resistance vessels within the lesions. Contractures and spasticity were observed in 18.4%. US allowed reliable guidance for Botulinum toxin A injection. Relapsing osteoarthritis and acute arthritis were diagnosed in 15.3% and 7.3% respectively. Patients with MSC had lower Functional Independence Measurement (FIM) and Katz index scores in discharge (p < 0.04 and p < 0.0294 respectively) and more length of hospital stay (p = 0.0024). DISCUSSION: Musculoskeletal pathology frequently complicates the course of acquired brain injuries and it delays functional recovery. Bedside US is a cheap and sensitive diagnostic tool and it can aid clinicians to define diagnosis and to choose therapeutic approach.
RESUMO
Hand joint involvement in rheumatic diseases is often precocious and predominant as compared to other skeleton-muscular regions. Clinical examination not always allows for easy detection of fluid outpouring and synovial involvement, and undoubtedly does not allow to diagnose pathognomonic bone alterations of several rheumatic conditions. Articular ultrasonography is an innocuous methodology, easily reproducible and directly applied by a rheumatologist. The aim of this vignette is to present ultrasonography elementary lesions of the hand for a prompt diagnosis.

The aim of this retrospective, cross-sectional, controlled, non-population-based study was to evaluate the specificity and sensitivity of quantitative ultrasonometry (QUS) of the heel and of dual-energy X-ray absorptiometry (DXA) in the prediction of morphometric vertebral fracture in postmenopausal women and to establish whether the combination of the two devices could improve the capacity to identify the presence of vertebral fracture. Also, we tried to identify the best T-score threshold for high risk of vertebral fracture for both QUS and DXA, highlighting the discrepancies between the two methodologies and between the various sites examined with DXA. From 6,300 patients examined by DXA (total body, lumbar spine, total femur, femoral neck), QUS and DXA vertebral morphometry (MXA), we selected 764 postmenopausal women with nontraumatic vertebral fractures; 770 postmenopausal women with normal morphometry were chosen as a control group. Logistic regression analysis yielded odds ratios (ORs) for bone mineral density (BMD) measurements and QUS that were comparable: BMD-total body 4.16, BMD-lumbar spine 4.80, BMD-total femur 3.77, BMD-femoral neck 3.86, and QUS 4.41, without statistical differences even after correction for different confounding variables (menopausal years, weight, height, body mass index, and age). The ORs obtained from different combinations of QUS and DXA results did not show statistically significant differences compared to those from a single method alone. The sensitivity and specificity of all measurements were determined by area using the receiver operating characteristic curve; these were 0.94 for total body, 0.95 for lumbar spine, 0.86 for total femur, 0.89 for femoral neck, and 0.93 for QUS, without statistical difference. The areas under the curve obtained from the combination of QUS and DXA were higher but without statistical significance compared to QUS alone. In conclusion, both QUS and DXA were able to discriminate women with fracture from women without fracture and independently contributed to determining the association with fracture. The combination of QUS and BMD did not improve the diagnostic ability of either individual technique. We found different diagnostic thresholds for QUS and DXA.

OBJECTIVE: To study heel fat pad (HFP) inflammatory-oedematous lesions in selected patients with rheumatoid arthritis (RA) using ultrasonography (US) and power Doppler US (PDUS), to describe and compare US features of these lesions with those obtained with magnetic resonance imaging (MRI), and to describe changes in the lesions after a short-term follow-up with conventional or anti-tumour necrosis factor-alpha (TNFalpha) therapy. METHODS: Twelve heels of eight RA outpatients with HFP inflammatory-oedematous lesions were studied by US, PDUS, and unenhanced MRI. All the patients were followed up and US was performed after 3 months. Five patients started on anti-TNFalpha therapy. RESULTS: HFP lesions appeared at US as a heterogeneous and hypoechoic subcalcaneal mass, with loss of normal lobular structure and increased thickness of HFP, because of focal rupture of fibrous septae with oedema and fluid. PDUS showed peripheral vascularization of HFP lesions in 9/12 heels. In 3/12 heels some vascular signals was also detectable inside the lesion, always along the residual echoic septa. No detectable flow was observed within the central fluid-filled spaces. MRI of the HFP lesions showed areas of mean intensity in T1-weighted sequences and high intensity in T2-weighted sequences, with poorly or well-defined margins. After 3 months, PDUS showed reduction in HFP lesion vascularity (associated with reduction in pain) in 10/12 heels, while poor regression of grey-scale US abnormalities was observed. CONCLUSIONS: Both US and MRI are capable of demonstrating structural abnormalities in the HFP. PDUS is useful to assess and monitor inflammatory vascularization of the HFP lesions.

OBJECTIVE: To investigate by high frequency ultrasonography the appearance of calcium pyrophosphate dihydrate (CPPD) calcifications, in the most commonly affected sites in CPPD disease, and the relationship between ultrasonographic CPPD deposits and the presence of CPPD crystals in synovial fluid. METHODS: Three ultrasonographic patterns of CPPD calcification were identified and 11 patients enrolled. A control group comprised 13 patients with no evidence of CPPD deposits. Synovial fluid was aspirated from all patients and controls and examined for identification of crystals. All patients underwent a standard radiography examination at the same sites investigated by ultrasound. RESULTS: In all patients with ultrasonographically defined CPPD deposits, CPPD crystals were found in the synovial fluid. In two cases, standard radiographic examination did not show evidence of the calcific deposits that were identified by ultrasonography. CPPD crystals were not found in the synovial fluid of controls. In four control group patients, ultrasonography identified calcifications defined as deposits of another nature. CONCLUSIONS: The ultrasonographic pattern used in this study for the diagnosis of CPPD disease demonstrated a very high correlation with the presence of CPPD crystals in synovial fluid. Ultrasonography demonstrated a sensitivity and specificity at least equal to that of radiography in identifying CPPD crystal calcifications.

BACKGROUND: Heel fat pad inflammation and degeneration have been frequently proved to cause talalgia. Painful heel fat pad is often confused with plantar fasciitis, and only magnetic resonance imaging (MRI) or ultrasonography (US) can differentiate these conditions. Scanty data are available about heel fat pad involvement in the course of chronic polyarthritis. OBJECTIVE: To investigate with US the heel fat pad involvement in patients with rheumatoid arthritis (RA) and spondyloarthropathies (SpA); to describe and compare the clinical and sonographic features of this lesion in the two groups. METHODS: The heels of 181 consecutive outpatients with RA and 160 with SpA were studied by US and radiography. A control group of 60 healthy subjects was examined by US. RESULTS: Two different patterns of involvement of the heel fat pad were observed. The inflammatory-oedematous pattern was more frequent in patients with RA (6.6%) than in those with SpA (1.8%), and was associated with talalgia--even if it was not associated with plantar fasciitis or enthesophyte (bony spur). The degenerative-atrophic pattern was less frequent (1.1% in RA, 1.9% in SpA), and was associated with plantar fasciitis and subcalcaneal enthesophyte. CONCLUSIONS: The inflammatory-oedematous lesion of the heel fat-pad is relatively frequent in RA and causes subcalcaneal pain. Degenerative-atrophic changes of the heel fat pad can be observed in RA and SpA, and seem to be associated with chronic abnormalities of the plantar fascia and of its enthesis.

OBJECTIVE: The aim of this study was to evaluate bone mass and bone ultrasonometry in patients affected with systemic sclerosis (SSc). METHODS: Fifty-five patients (mean age 54.1 +/- 14.1 years; 25 premenopausal, and 30 postmenopausal women) affected with SSc (in a limited, intermediate or diffused form) and 60 age-matched healthy controls (30 premenopausal, and 30 postmenopausal women) were studied for Bone Mineral Density (BMD) measured by fan-beam x-ray densitometry, Stiffness Index (SI) measured by ultrasonometry of the heel, inflammation indices (erithrocyte sedimentation rate, C-reactive protein), and autoantibodies (ANA, ENA). Examinations were also carried out in order to determine any internal organ involvement. None of the patients had previously received steroid treatment. RESULTS: BMD was significantly lower in the SSc group than in the control group, whether it was expressed in g/cm2 (lumbar spine: 0.980 vs 1.241, p < 0.01; femoral neck: 0.832 vs 0.955, p < 0.05; total body 1.050 vs 1.168, p < 0.01) or by T- and Z-score (lumbar spine: T = -2.48; Z = -1.10; femoral neck: T = -1.69; Z = -0.55; total body: T = -1.11; Z = -0.48). SI was also altered (75.8 vs 96.2, p < 0.01; T = -2.10, Z = -1.12). BMD and SI were lower in women with the diffuse form of skin involvement. BMD and SI were lower in women in whom one or more internal organs were involved. CONCLUSION: SSc patients had reduced BMD and SI that was more marked in the diffuse form and in those with internal organ involvement and that became more marked with age and estrogen deficiency. This demineralisation was not related to the inflammation indices, disease duration, or to the immunological pattern.

OBJECTIVE: To establish by ultrasonography (US) the frequency of calcaneal entheses involvement in erosive osteoarthritis (EOA), nodal osteoarthritis (NOA), RA and PsA, and to compare these results in order to aid clinicians in the differential diagnosis among these diseases. A comparison between US results and radiography was also made. METHODS: The heels of 56 consecutive outpatients with EOA, 209 with NOA, 158 with RA and 125 with PsA were studied by US and radiography. A control group of 50 subjects was examined by US. RESULTS: US showed no significant difference in inferior calcaneal enthesophytosis among the four diseases. The frequency of posterioinferior enthesophytosis was lower in RA (34%) in comparison with the other diseases (57% in EOA, 47% in NOA, 49% in PsA). Achilles enthesitis was found in 8% of PsA and in 2% of RA. Retrocalcaneal bursitis was found in 18% of RA and in 6% of PsA. Posterior erosions were present in 12% of RA and 5% of PsA. Inferior erosions were present in 6% of RA and in 1% of PsA. Plantar fasciitis was found in 26% of RA, in 37% of PsA, and in 15% of NOA and 12% of EOA. Subcalcaneal panniculitis was observed in 10% of RA and in 1% of PsA. In the control group, only posterioinferior and inferior enthesophytosis (22% and 18% respectively) were found. Kappa statistics show excellent agreement between US and radiography in detecting posterioinferior (kappa = 0.89) and inferior enthesophytosis (kappa = 0.83), and entheseal erosions (kappa = 0.86). CONCLUSIONS: The calcaneal lesions that could be found in EOA are similar to those observed in NOA. The frequency of calcaneal enthesophytosis is similar in EOA, NOA, and PsA, but inflammatory lesions of calcaneal entheses and of the adjacent bursae are more frequent in RA and in PsA. In terms of heel involvement, EOA seems to be similar to NOA. US shows an excellent concordance with radiography in detecting entheseal cortical bone abnormalities.

The aim of this placebo-controlled study was to determine whether once-weekly clodronate could prevent osteoporosis in patients with arthritis at the start of corticosteroid therapy. One hundred sixty-three patients, 18 to 90 years of age, with rheumatoid or psoriatic arthritis, were randomly assigned to receive either clodronate (100 mg im/week) plus calcium and vitamin D (1000 mg and 800 UI, respectively) or calcium and vitamin D alone. Patients had started therapy with prednisone or its equivalent within the previous 100 days and had bone mineral density <2.5 SD below mean young normal values at the lumbar spine or femoral neck. The primary outcome was the difference between the two treatment groups at months 12, 24, 36, and 48 in the mean percentage change from baseline in the bone mineral density of the lumbar spine, femur (neck and total), and total body. Secondary measurements included changes in the stiffness index evaluated by ultrasound measurements and the rate of new vertebral fractures. The bone density and stiffness did not change significantly in the clodronate plus calcium and vitamin D group, whereas it declined significantly in the calcium plus vitamin D group. The difference between treatment groups at 48 months in the mean change from baseline was 8.78 +/- 1.4% for the lumbar spine (P < 0.01), 7.31 +/- 1.12% for the femoral neck (P < 0.01), 7.92 +/- 1.93% for the trochanter (P < 0.01), 8.39 +/- 1.80% for total femur (P < 0.01), 6.94 +/- 1.09% for total body (P < 0.01), and 9.38 +/- 2.21% for stiffness of os calcis (P < 0.01). Depending on the skeletal regions evaluated, 85 to 98% of patients treated with clodronate had a densitometric change lower than the lowest significant densitometric difference. One hundred percent of patients treated with calcium plus vitamin D had a densitometric decrease greater than the lowest significant difference. The relative risk of vertebral fractures and multiple vertebral fractures in the clodronate group compared to the calcium plus vitamin D group was 0.63 (0.35-0.98, 95% CI) and 0.25 (0.15-0.91, 95% CI), respectively. We concluded that pulsatory administration of im clodronate once weekly is a safe therapy for preventing corticosteroid induced osteoporosis in patients with arthritis.

Enthesitis is an inflammatory lesion of the tendon, ligament and capsular insertions into the bone, and it is a fundamental element in the diagnosis of spondyloarthropathies. Sonography is the method of choice for studying periarticular soft tissues because it is capable of detecting both the early (oedema, thickening) and late alterations (erosions and enthesophytes); it is also an inexpensive, biologically harmless and easily repeatable technique. The aim of this study was to compare the prevalence of quadricipital enthesitis in psoriatic arthritis (PsA) and rheumatoid arthritis (RA) patients, and to document any clinical and echostructural differences in this lesion between the two diseases. The results show that enthesitis is more frequent in PsA patients, more than half of whom are asymptomatic. Knee inflammation was found in the PsA patients with enthesitis regardless of the concomitant presence of joint effusion; none of the RA patients suffered from enthesitis alone. Quadricipital enthesitis is more frequent in male patients. There was no significant correlation between the presence of peripatellar psoriatic lesions and enthesitis. Sonographic examinations of patients with enthesitis revealed that those with RA had predominantly inflammatory lesions, whereas PsA patients also showed major new bone deposition.

OBJECTIVE: To evaluate the efficacy of extracorporeal shock wave treatment (ESWT) in calcaneal enthesophytosis. METHODS: 60 patients (43 women, 17 men) were examined who had talalgia associated with heel spur. A single blind randomised study was performed in which 30 patients underwent a regular treatment (group 1) and 30 a simulated one (shocks of 0 mJ/mm(2) energy were applied) (group 2). Variations in symptoms were evaluated by visual analogue scale (VAS). Variations in the dimension of enthesophytosis were evaluated by x ray examination. Variations in the grade of enthesitis were evaluated by sonography. RESULTS: A significant decrease of VAS was seen in group 1. Examination by x ray showed morphological modifications (reduction of the larger diameter >1 mm) of the enthesophytosis in nine (30%) patients. Sonography did not show significant changes in the grade of enthesitis just after the end of the treatment, but a significant reduction was seen after one month. In the control group no significant decrease of VAS was seen. No modification was observed by x ray examination or sonography. CONCLUSION: ESWT is safe and improves the symptoms of most patients with a painful heel, it can also structurally modify enthesophytosis, and reduce inflammatory oedema.

OBJECTIVE: Little information is available concerning bone mass in patients with psoriatic arthritis (PsA): the existence of less severe periarticular osteoporosis is considered possible, but there are no data concerning the existence of systemic osteoporosis. We investigated bone mineral density (BMD) in patients with PsA. METHODS: We studied 186 patients with non-axial PsA and 100 healthy subjects, equally divided into 3 groups: women of child-bearing age, women in menopause, and men. No patient had previously received steroid treatment. In all patients, evaluation was made of disease duration, inflammation indices (erythrocyte sedimentation rate, C-reactive protein), functional indices (Steinbrocker scale), and the Health Assessment Questionnaire (HAQ). BMD was measured by fan-beam x-ray densitometry of the lumbar spine, femur, and total body (evaluating the whole skeleton, as well as the spine, trunk, and upper and lower limbs). Ultrasound densitometry of the heel was also performed. RESULTS: BMD was significantly lower in the arthritic than in the healthy subjects regardless of sex, menopausal status, or age, as expressed in g/cm2 (lumbar spine 1.112 vs 1.326; femoral neck 0.870 vs 1.006; total body 1.125 vs 1.203) or by T and Z scores (lumbar T = -1.36, Z = -0.98; femoral neck T = -1.12, Z = -0.83; total body T = -1.09, Z = -0.65). Ultrasound densitometry of the heel was similarly altered (stiffness 96 vs 77; T -1.78; Z -1.29). Among the PsA patients, demineralization in at least one skeletal region was observed in 67% of premenopausal women (marked in 11%), 100% of postmenopausal women (marked in 47%), and 80% of the men (marked in 29%). In premenopausal women, demineralization did not correlate with the disease variables; in postmenopausal women and the men, it correlated with a decline in the functional indices and the HAQ score. This was confirmed by analysis of the relative risk of osteoporosis expressed in odds ratios (HAQ: 1.6; age: 1.4; years since menopause: 1.7). CONCLUSION: Demineralization was observed in more than 2/3 of our PsA patients without axial involvement. This demineralization was not related to the indices of inflammation or disease duration, but there is a delayed correlation with HAQ score, as well as age and the number of years since menopause.
