RESUMEN
OBJECTIVE: To examine associations of pain sensitisation with tender and painful joint counts and presence of widespread pain in people with hand osteoarthritis (OA). METHODS: Pressure pain thresholds (PPT) at a painful finger joint and the tibialis anterior muscle, and temporal summation (TS) were measured in 291 persons with hand OA. We examined whether sex-standardised PPT and TS values were associated with assessor-reported tender hand joint count, self-reported painful hand and total body joint counts and presence of widespread pain using linear and logistic regression analyses adjusted for age, sex, body mass index, education and OA severity. RESULTS: People with lower PPTs at the painful finger joint (measure of peripheral and/or central sensitisation) had more tender and painful hand joints than people with higher PPTs. PPT at tibialis anterior (measure of central sensitisation) was associated with painful total body joint count (beta=-0.82, 95% CI -1.28 to -0.35) and presence of widespread pain (OR=0.57, 95% CI 0.43 to 0.77). The associations between TS (measure of central sensitisation) and joint counts in the hands and the total body were statistically non-significant. CONCLUSION: This cross-sectional study suggested that pain sensitisation (ie, lower PPTs) was associated with joint counts and widespread pain in hand OA. This knowledge may be used for improved pain phenotyping of people with hand OA, which may contribute to better pain management through more personalised medicine. Further studies are needed to assess whether a reduction of pain sensitisation leads to a decrease in tender and painful joint counts.

OBJECTIVES: To investigate whether Fluorescence Optical Imaging (FOI) enhancement and MRI-defined synovitis are associated with pain and physical function in hand OA patients. METHODS: Bilateral FOI scans and MRI of the dominant hand were available for 221 patients. Finger joints were examined for tenderness on palpation. Pain in individual finger joints during the last 24 h and last 6 weeks and hand pain intensity by the Australian/Canadian hand index and Numeric Rating Scale were self-reported. On joint level, we applied logistic regression with generalized estimating equations to examine whether FOI enhancement and MRI-defined synovitis were associated with pain in the same joint. On subject level, we applied linear regression to assess whether FOI and MRI sum scores were associated with pain intensity and physical function. RESULTS: Metacarpophalangeal and thumb base joints were excluded from analyses due to little/no FOI enhancement. Finger joints with FOI enhancement on the composite image had higher odds (95% CI) of pain during the last 6 weeks [grade 1: 1.4 (1.2-1.6); grade 2-3: 2.1 (1.7-2.6)]. Similar results were found for joint pain during the last 24 h and joint tenderness in fingers. Numerically stronger associations were found between MRI-defined synovitis and finger joint pain/tenderness. FOI and MRI sum scores demonstrated no/weak associations with hand pain and physical function. CONCLUSION: FOI enhancement and MRI-defined synovitis were associated with pain in the same finger joint. None of the imaging modalities demonstrated consistent associations with pain, stiffness and physical function on subject level.

BACKGROUND: Current health policy states that patients with osteoarthritis (OA) should mainly be managed in primary health care. Still, research shows that patients with hand OA have poor access to recommended treatment in primary care, and in Norway, they are increasingly referred to rheumatologist consultations in specialist care. In this randomized controlled non-inferiority trial, we will test if a new model, where patients referred to consultation in specialist health care receive their first consultation by an occupational therapy (OT) specialist, is as safe and effective as the traditional model, where they receive their first consultation by a rheumatologist. More specifically, we will answer the following questions: 1. What are the characteristics of patients with hand OA referred to specialist health care with regards to joint affection, disease activity, symptoms and function? 2. Is OT-led hand OA care as effective and safe as rheumatologist-led care with respect to treatment response, disease activity, symptoms, function and patient satisfaction? 3. Is OT-led hand OA care equal to, or more cost effective than rheumatologist-led care? 4. Which factors, regardless of hand OA care, predict improvement 6 and 12 months after baseline? METHODS: Participants will be patients with hand OA diagnosed by a general practitioner and referred for consultation at one of two Norwegian departments of rheumatology. Those who agree will attend a clinical assessment and report their symptoms and function in validated outcome measures, before they are randomly selected to receive their first consultation by an OT specialist (n = 200) or by a rheumatologist (n = 200). OTs may refer patients to a rheumatologist consultation and vice versa. The primary outcome will be the number of patients classified as OMERACT/OARSI-responders after six months. Secondary outcomes are pain, function and satisfaction with care over the twelve-month trial period. The analysis of the primary outcome will be done by logistic regression. A two-sided 95% confidence interval for the difference in response probability will be formed, and non-inferiority of OT-led care will be claimed if the upper endpoint of this interval does not exceed 15%. DISCUSSION: The findings will improve access to evidence-based management of people with hand OA. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03102788.

Objective: This study aims to increase the understanding of pain mechanisms in hand OA and explore potential risk factors for pain development or worsening in a biopsychosocial framework. Another important aim is to validate potential soluble and imaging OA biomarkers. Design: The follow-up examination of the Nor-Hand hospital-based observational cohort study started in October 2019 and was completed in May 2021. In total, 212 of the 300 participants with hand OA who were examined at baseline attended the follow-up study. The participants underwent clinical joint examinations, medical and functional assessments, quantitative sensory testing, fluorescence optical imaging, ultrasound of the hands, acromioclavicular joints, feet, knees and hips, conventional radiographs of the hands and feet and magnetic resonance imaging of the dominant hand. Blood and urine samples were collected, and all participants answered questions about demographic factors and OA-related questionnaires. Associations between disease variables and symptoms will be examined in cross-sectional and longitudinal analyses. Longitudinal analyses will be performed to assess the predictive value of baseline variables on hand OA outcomes. Conclusion: Current knowledge about predictors for disease progression in hand OA is limited, but with longitudinal data we will be able to explore the predictive value of baseline variables on hand OA outcomes, such as changes in patient-reported outcomes or changes in soluble and imaging biomarkers. This provides a unique opportunity to gain more knowledge about the natural disease course of hand OA.
RESUMEN
OBJECTIVE: To explore whether ultrasound-detected gray-scale synovitis and power Doppler activity in the interphalangeal and first carpometacarpal (CMC1) joints are associated with pain and physical function in patients with hand osteoarthritis (OA). METHODS: A total of 290 patients with hand OA underwent an ultrasound examination of the bilateral interphalangeal and CMC1 joints. Using logistic regression analyses with generalized estimating equations, we examined whether grade 0-3 gray-scale synovitis and power Doppler activity were associated with pain in the same joint. Using linear regression analyses, we examined whether the degree of inflammation was associated with numeric rating scale and Australian/Canadian (AUSCAN) Osteoarthritis Hand Index hand pain, AUSCAN physical function, and grip strength scores. Analyses were made separately for interphalangeal and CMC1 joints, and adjusted for age, sex, body mass index, psychosocial factors, use of analgesics, and presence of osteophytes. RESULTS: At joint level, increasing gray-scale synovitis severity was associated with higher odds of pain upon palpation in both the interphalangeal (grade 2-3; odds ratio [OR] 3.17 [95% confidence interval (95% CI) 2.35, 4.28]) and CMC1 joints (grade 2-3; OR 4.40 [95% CI 2.10, 9.24]). Similar associations were found for power Doppler activity and joint pain in the previous 24 hours and 6 weeks. Power Doppler activity in CMC1 was also related to overall hand pain/physical function and lower grip strength. CONCLUSION: Inflammation in both the interphalangeal and CMC1 joints was associated with pain in the same joint. However, associations with hand pain, reduced physical function, and lower grip strength were only present for inflammation in the CMC1 joints, suggesting that lowering CMC1 inflammation is an important treatment target.

OBJECTIVE: It is currently unknown whether osteoarthritis (OA) is inherited mainly from the mother, father, or both. This study was undertaken to explore the effect of maternal and paternal factors on hip, knee, and hand OA in offspring. METHODS: Participants from the Musculoskeletal Pain in Ullensaker Study (MUST) (69% female; mean ± SD age 64 ± 9 years) and a Norwegian OA twin study (Nor-Twin) (56% female; 49 ± 11 years) reported whether their mother and/or father had OA. Using a recurrence risk estimation approach, we calculated whether maternal and paternal OA increased the risk of 1) surgically defined hip and knee OA (i.e., total joint replacement) and 2) clinically defined hip, knee, and hand OA (i.e., the American College of Rheumatology criteria) using logistic regression. Relative risks (RRs) with 95% confidence intervals (95% CIs) were calculated. RESULTS: Maternal OA consistently increased the risk of offspring OA across different OA locations and severities. Having a mother with OA increased the risk of any OA in daughters (RR 1.13 [95% CI 1.02-1.25] in the MUST cohort; RR 1.44 [95% CI 1.05-1.97] in the Nor-Twin cohort) but not (or with less certainty) in sons (RR 1.16 [95% CI 0.95-1.43] in the MUST cohort; RR 1.31 [95% CI 0.71-2.41] in the Nor-Twin cohort). Having a father with OA was less likely to increase the risk of any OA in daughters (RR 1.00 [95% CI 0.85-1.16] in the MUST cohort; RR 1.52 [95% CI 0.94-2.46] in the Nor-Twin cohort) and sons (RR 1.08 [95% CI 0.83-1.41] in the MUST cohort; RR 0.93 [95% CI 0.35-2.48] in the Nor-Twin cohort). CONCLUSION: OA in the mother increased the risk of surgically and clinically defined hip, knee, and hand OA in offspring, particularly in daughters. Our findings imply that heredity of OA may be linked to maternal genes and/or maternal-specific factors such as the fetal environment.

OBJECTIVE: To assess the benefits and harms of exercise compared with other interventions, including placebo or no intervention, in people with hand osteoarthritis (OA). METHODS: Systematic review using Cochrane Collaboration methodology. Six electronic databases were searched up until September 2015. INCLUSION CRITERIA: randomized or controlled clinical trials comparing therapeutic exercise versus no exercise, or comparing different exercise programs. MAIN OUTCOMES: hand pain, hand function, finger joint stiffness, quality of life, adverse events, and withdrawals because of adverse effects. Risk of bias and quality of the evidence were assessed. RESULTS: Seven trials were included in the review, and up to 5 trials (n = 381) were included in the pooled analyses with data from postintervention. Compared to no exercise, low-quality evidence indicated that exercise may improve hand pain [5 trials, standardized mean difference (SMD) -0.27, 95% CI -0.47 to -0.07], hand function (4 trials, SMD -0.28, 95% CI -0.58 to 0.02), and finger joint stiffness (4 trials, SMD -0.36, 95% CI -0.58 to -0.15) in people with hand OA. Quality of life was evaluated by 1 study (113 participants) showing very low-quality evidence for no difference. Three studies reported on adverse events, which were very few and not severe. CONCLUSION: Pooled results from 5 studies with low risk of bias showed low-quality evidence for small to moderate beneficial effects of exercise on hand pain, function, and finger joint stiffness postintervention. Estimated effect sizes were small, and whether they represent a clinically important change may be debated.

INTRODUCTION: We have limited knowledge about the underlying disease mechanisms and causes of pain in hand osteoarthritis (OA). Consequently, no disease-modifying drug exists, and more knowledge about the pathogenesis of hand OA is needed, as well as a validation of different outcome measures. Our first aim of this study is to explore the validity of various imaging modalities for the assessment of hand OA. Second, we want to gain a better understanding of the disease processes, with a special focus on pain mechanisms. METHODS AND ANALYSIS: The Nor-Hand study is a hospital-based observational study including 300 patients with evidence of hand OA by ultrasound and/or clinical examination. The baseline examination consists of functional tests and joint assessment of the hands, medical assessment, pain sensitisation tests, ultrasound (hands, acromioclavicular joint, hips, knees and feet), CT and MRI of the dominant hand, conventional radiographs of the hands and feet, fluorescence optical imaging of the hands, collection of blood and urine samples as well as self-reported demographic factors and OA-related questionnaires. Two follow-up examinations are planned. Cross-sectional analyses will be used to investigate agreements and associations between different relevant measures at the baseline examination, whereas the longitudinal data will be used for evaluation of predictors for clinical outcomes. ETHICS AND DISSEMINATION: The protocol is approved by the Norwegian Regional Committee for Medical and Health Research Ethics (Ref. no: 2014/2057). The participants receive oral and written information about the project and sign a consent form before participation. They can, whenever they want, withdraw from the study, and all de-identified data will be safely stored on the research server at Diakonhjemmet Hospital. Results will be presented at international and national congresses and in peer-reviewed rheumatology journals. TRIAL REGISTRATION NUMBER: NCT03083548; Pre-results.

BACKGROUND: Structural pathology may be present in joints without radiographic evidence of osteoarthritis (OA). Ultrasound is a sensitive tool for early detection of osteophytes. Our aim was to explore whether ultrasound-detected osteophytes (in radiographically and clinically normal finger joints) predicted the development of radiographic and clinical hand OA 5 years later. METHODS: We included finger joints without radiographic OA (Kellgren-Lawrence grade (KLG)=0; n=301) or no clinical bony enlargements (n=717) at baseline and examined whether ultrasound-detected osteophytes predicted incident radiographic OA (KLG ≥1, osteophytes or joint space narrowing (JSN)) or incident clinical bony enlargement (dependent variables) in the same joints 5 years later. We applied logistic regression with generalised estimating equations adjusted for age, sex, body mass index and follow-up time. RESULTS: Ultrasound demonstrated osteophytes in 86/301 (28.6%) joints without radiographic OA and 392/717 (54.7%) joints without clinical bony enlargement. These osteophytes were confirmed in the majority of joints where MRI assessment was available. Significant associations were found between ultrasound-detected osteophytes and development of both radiographic OA (OR=4.1, 95% CI 2.0 to 8.1) and clinical bony enlargement (OR=3.5, 95% CI 2.4 to 5.1) and also incident radiographic osteophytes (OR=4.2, 95% CI 2.1 to 8.5) and JSN (OR=5.3, 95% CI 2.1 to 13.4). CONCLUSION: Ultrasound-detected osteophytes predicted incident radiographic and clinical hand OA 5 years later. These results support the use of ultrasound for early detection of OA.
RESUMEN
BACKGROUND: Hand osteoarthritis (OA) is a prevalent joint disease that may lead to pain, stiffness and problems in performing hand-related activities of daily living. Currently, no cure for OA is known, and non-pharmacological modalities are recommended as first-line care. A positive effect of exercise in hip and knee OA has been documented, but the effect of exercise on hand OA remains uncertain. OBJECTIVES: To assess the benefits and harms of exercise compared with other interventions, including placebo or no intervention, in people with hand OA. Main outcomes are hand pain and hand function. SEARCH METHODS: We searched six electronic databases up until September 2015. SELECTION CRITERIA: All randomised and controlled clinical trials comparing therapeutic exercise versus no exercise or comparing different exercise programmes. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials, extracted data, assessed risk of bias and assessed the quality of the body of evidence using the GRADE approach. Outcomes consisted of both continuous (hand pain, physical function, finger joint stiffness and quality of life) and dichotomous outcomes (proportions of adverse events and withdrawals). MAIN RESULTS: We included seven studies in the review. Most studies were free from selection and reporting bias, but one study was available only as a congress abstract. It was not possible to blind participants to treatment allocation, and although most studies reported blinded outcome assessors, some outcomes (pain, function, stiffness and quality of life) were self-reported. The results may be vulnerable to performance and detection bias owing to unblinded participants and self-reported outcomes. Two studies with high drop-out rates may be vulnerable to attrition bias. We downgraded the overall quality of the body of evidence to low owing to potential detection bias (lack of blinding of participants on self-reported outcomes) and imprecision (studies were few, the number of participants was limited and confidence intervals were wide for the outcomes pain, function and joint stiffness). For quality of life, adverse events and withdrawals due to adverse events, we further downgraded the overall quality of the body of evidence to very low because studies were very few and confidence intervals were very wide.Low-quality evidence from five trials (381 participants) indicated that exercise reduced hand pain (standardised mean difference (SMD) -0.27, 95% confidence interval (CI) -0.47 to -0.07) post intervention. The absolute reduction in pain for the exercise group, compared with the control group, was 5% (1% to 9%) on a 0 to 10 point scale. Pain was estimated to be 3.9 points on this scale (0 = no pain) in the control group, and exercise reduced pain by 0.5 points (95% CI 0.1 to 0.9; number needed to treat for an additional beneficial outcome (NNTB) 9).Four studies (369 participants) indicated that exercise improved hand function (SMD -0.28, 95% CI -0.58 to 0.02) post intervention. The absolute improvement in function noted in the exercise group, compared with the control group, was 6% (0.4% worsening to 13% improvement). Function was estimated at 14.5 points on a 0 to 36 point scale (0 = no physical disability) in the control group, and exercise improved function by 2.2 points (95% CI -0.2 to 4.6; NNTB 9).One study (113 participants) evaluated quality of life, and the effect of exercise on quality of life is currently uncertain (mean difference (MD) 0.30, 95% CI -3.72 to 4.32). The absolute improvement in quality of life for the exercise group, compared with the control group, was 0.3% (4% worsening to 4% improvement). Quality of life was 50.4 points on a 0 to 100 point scale (100 = maximum quality of life) in the control group, and the mean score in the exercise group was 0.3 points higher (3.5 points lower to 4.1 points higher).Four studies (369 participants) indicated that exercise reduced finger joint stiffness (SMD -0.36, 95% CI -0.58 to -0.15) post intervention. The absolute reduction in finger joint stiffness for the exercise group, compared with the control group, was 7% (3% to 10%). Finger joint stiffness was estimated at 4.5 points on a 0 to 10 point scale (0 = no stiffness) in the control group, and exercise improved stiffness by 0.7 points (95% CI 0.3 to 1.0; NNTB 7).Three studies reported intervention-related adverse events and withdrawals due to adverse events. The few reported adverse events consisted of increased finger joint inflammation and hand pain. Low-quality evidence from the three studies showed an increased likelihood of adverse events (risk ratio (RR) 4.55, 95% CI 0.53 to 39.31) and of withdrawals due to adverse events in the exercise group compared with the control group (RR 2.88, 95% CI 0.30 to 27.18), but the effect is uncertain and further research may change the estimates.Included studies did not measure radiographic joint structure changes. Two studies provided six-month follow-up data (220 participants), and one (102 participants) provided 12-month follow-up data. The positive effect of exercise on pain, function and joint stiffness was not sustained at medium- and long-term follow-up.The exercise intervention varied largely in terms of dosage, content and number of supervised sessions. Participants were instructed to exercise two to three times a week in four studies, daily in two studies and three to four times daily in another study. Exercise interventions in all seven studies aimed to improve muscle strength and joint stability or function, but the numbers and types of exercises varied largely across studies. Four studies reported adherence to the exercise programme; in three studies, this was self-reported. Self-reported adherence to the recommended frequency of exercise sessions ranged between 78% and 94%. In the fourth study, 67% fulfilled at least 16 of the 18 scheduled exercise sessions. AUTHORS' CONCLUSIONS: When we pooled results from five studies, we found low-quality evidence showing small beneficial effects of exercise on hand pain, function and finger joint stiffness. Estimated effect sizes were small, and whether they represent a clinically important change may be debated. One study reported quality of life, and the effect is uncertain. Three studies reported on adverse events, which were very few and were not severe.

Objective: . The aim was to explore the agreement between 1.0 T MRI and conventional radiography (CR) to detect progression of hand OA over 5 years and the associations between structural progression and incident joint tenderness. Methods: Paired radiographs and paired MRIs of the second-fifth IP joints of the dominant hand from 69 hand OA patients were read for osteophytes, joint space narrowing and erosions. Patients with two or more joints demonstrating progression of any structural feature(s) were classified as progressors per imaging modality. Agreement between methods to detect progressors was evaluated with κ and intraclass correlation coefficients. At the joint level, the associations between methods to detect progression were explored with generalized estimating equations. Likewise, we analysed the associations between progression per imaging modality and incident pain. Results: MRI (58.0%) and CR (62.3%) detected similar numbers of progressors. The agreement between methods to detect progressors was good (κ = 0.61). We found good agreement between methods regarding the number of progressive joints (intraclass correlation coefficient = 0.61, 95% CI: 0.43, 0.76). At the joint level, MRI progression was associated with radiographic progression (P < 0.001). Incident joint tenderness was more common in joints with progression by MRI and CR, but statistically significance was not reached. Conclusion: Both 1.0 T MRI and CR detect a similar amount of progression over 5 years in patients with hand OA, although not in exactly the same joints. As CR assesses more joints for a lower cost, CR should be the imaging modality of choice rather than 1.0 T MRI in observational studies with a long period of follow-up.

OBJECTIVE: To examine whether ultrasound predicts radiographic hand osteoarthritis (OA) progression after 5â years. METHODS: We included 78 participants (71 women, mean (SD) age 67.8 (5.2) years) from the Oslo Hand OA cohort with ultrasound examination (gray-scale (GS) synovitis and power Doppler (PD) signals) at baseline and conventional radiographs and clinical examination at baseline and 5-year follow-up. Radiographic progression was defined as an increase in global OA according to the Kellgren-Lawrence (KL) scale or progression of individual radiographic OA features. We examined whether baseline ultrasound features and clinical examination predicted radiographic progression using generalised estimating equations, adjusted for age, sex, body mass index and follow-up time. RESULTS: Radiographic progression occurred in 17.9% joints for KL, 12.1% for joint space narrowing, 11.7% for osteophytes and 4.5% for erosions. Ultrasound-detected inflammation predicted KL progression, and dose-response associations were observed for GS synovitis grade 1 (OR=2.8, 95% CI 1.8 to 4.2), grade 2 (OR=3.6, 95% CI 2.2 to 5.8) and grade 3 (OR=15.2, 95% CI 6.9 to 33.6), and for PD signal grade 1 (OR=2.9, 95% CI 1.2 to 6.8) and grades 2-3 (OR=12.0, 95% CI 3.5 to 41.0). Significant associations were also observed between ultrasound inflammation and progression of all individual radiographic features, and between clinical soft tissue swelling at baseline and radiographic progression. CONCLUSIONS: Ultrasound-detected GS synovitis and PD signals were significantly associated with radiographic progression after 5â years. This study supports the use of ultrasound as a tool to detect patients with hand OA who are likely to progress.

OBJECTIVES: To explore whether changes of MRI-defined synovitis and bone marrow lesions (BMLs) are related to changes in joint tenderness in a 5-year longitudinal study of the Oslo hand osteoarthritis (OA) cohort. METHODS: We included 70 patients (63 women, mean (SD) age 67.9 (5.5) years). BMLs and contrast-enhanced synovitis in the distal and proximal interphalangeal joints were evaluated on 0-3 scales in n=69 and n=48 patients, respectively. Among joints without tenderness at baseline, we explored whether increasing/incident synovitis and BMLs were associated with incident joint tenderness using generalised estimating equations. Among joints with tenderness at baseline, we explored whether decreasing or resolution of synovitis and BMLs were associated with loss of joint tenderness. We adjusted for age, sex, body mass index, follow-up time and changes in radiographic OA. RESULTS: Among joints without tenderness at baseline, increasing/incident synovitis and BMLs were seen in 45 of 220 (20.5%) and 47 of 312 (15.1%) joints, respectively. Statistically significant associations to incident joint tenderness were found for increasing/incident synovitis (OR=2.66, 95% CI 1.38 to 5.11) and BMLs (OR=2.85, 95% CI 1.23 to 6.58) independent of structural progression. We found a trend that resolution of synovitis (OR=1.72, 95% CI 0.80 to 3.68) and moderate/large decreases of BMLs (OR=1.90, 95% CI 0.57 to 6.33) were associated with loss of joint tenderness, but these associations were non-significant. CONCLUSIONS: The Oslo hand OA cohort is the first study with longitudinal hand MRIs. Increasing synovitis and BMLs were significantly associated with incident joint tenderness, whereas no significant associations were found for decreasing or loss of synovitis and BMLs.

OBJECTIVES: To examine whether MRI features predict radiographic progression including erosive evolution in patients from the Oslo hand osteoarthritis (OA) cohort, which is the first longitudinal hand OA study with available MRI. METHODS: We included 74 patients (91% female, mean (SD) age of 67.9 (5.3) years) with MRI of the dominant hand and conventional radiographs taken at baseline and 5-year follow-up. Baseline MRIs were read according to the Oslo hand OA MRI score. We used three definitions of radiographic progression: Progression of joint space narrowing (JSN, grades 0-3), increased Kellgren-Lawrence score (grades 0-4) or incident erosions (absent/present). For each definition, we examined whether MRI features predicted radiographic progression in the same joint using Generalised Estimating Equations. We adjusted for age, sex, Body Mass Index, follow-up time and other erosive joints (the latter for analyses on incident erosions only). RESULTS: MRI-defined moderate/severe synovitis (OR=3.52, 95% CI 1.29 to 9.59), bone marrow lesions (BML) (OR=2.73, 95% CI 1.29 to 5.78) and JSN (severe JSN: OR=11.05, 95% CI 3.22 to 37.90) at baseline predicted progression of radiographic JSN. Similar results were found for increasing Kellgren-Lawrence score, except for weaker association for JSN. Baseline synovitis, BMLs, JSN, bone damage, osteophytes and malalignment were significantly associated with development of radiographic erosions, of which malalignment showed the strongest association (OR=10.18, 95% CI 2.01 to 51.64). CONCLUSIONS: BMLs, synovitis and JSN were the strongest predictors for radiographic progression. Malalignment was associated with incident erosions only. Future studies should explore whether reducing BMLs and inflammation can decrease the risk of structural progression.

AIMS: To explore the feasibility and assess the effect of a prefabricated soft thumb-base orthosis on pain, hand strength, and activity performance in persons with osteoarthritis of the CMC joint. METHODS: In this randomized controlled trial, 29 patients received hand exercises only (control group) and 30 patients received hand exercises and an orthosis (orthosis group). The primary outcome was pain, while secondary outcomes included grip and pinch strength, and self-reported symptoms and activity performance. Outcome assessments, and measures of grip strength and pain with and without orthosis in the orthosis group, were made after two months. RESULTS: 55 participants (mean age 70.5 years) completed all assessments. There were no significant differences between the groups in primary or secondary outcomes after two months. However, in the orthosis group, pain was significantly less when wearing the orthosis than when not wearing it. Participants reported that the orthosis felt uncomfortable during activities involving water and one-third wanted more support of the CMC joint. CONCLUSIONS: A soft prefabricated orthosis seems to have an immediate pain-relieving effect during use, but no effects in terms of less hand pain, or improved strength or activity performance when not worn.

BACKGROUND: Knowledge about the prevalence and consequences of osteoarthritis (OA) in the Norwegian population is limited. This study has been designed to gain a greater understanding of musculoskeletal pain in the general population with a focus on clinically and radiologically confirmed OA, as well as risk factors, consequences, and management of OA. METHODS/DESIGN: The Musculoskeletal pain in Ullensaker STudy (MUST) has been designed as an observational study comprising a population-based postal survey and a comprehensive clinical examination of a sub-sample with self-reported OA (MUST OA cohort). All inhabitants in Ullensaker municipality, Norway, aged 40 to 79 years receive the initial population-based postal survey questionnaire with questions about life style, general health, musculoskeletal pain, self-reported OA, comorbidities, health care utilisation, medication use, and functional ability. Participants who self-report OA in their hip, knee and/or hand joints are asked to attend a comprehensive clinical examination at Diakonhjemmet Hospital, Oslo, including a comprehensive medical examination, performance-based functional tests, different imaging modalities, cardiovascular assessment, blood and urine samples, and a number of patient-reported questionnaires including five OA disease specific instruments. Data will be merged with six national data registries. A subsample of those who receive the questionnaire has previously participated in postal surveys conducted in 1990, 1994, and 2004 with data on musculoskeletal pain and functional ability in addition to demographic characteristics and a number of health related factors. This subsample constitutes a population based cohort with 20 years follow-up. DISCUSSION: This protocol describes the design of an observational population-based study that will involve the collection of data from a postal survey on musculoskeletal pain, and a comprehensive clinical examination on those with self-reported hand, hip and/or knee OA. These data, in addition to data from national registries, will provide unique insights into clinically and radiologically confirmed OA with respect to risk factors, consequences, and management.

OBJECTIVE: To investigate the reliability of ultrasonographic assessment of osteophytes and explore the concordance of osteophytes detected by ultrasound, MRI, conventional radiography (CR) and clinical joint examination in patients with hand osteoarthritis (HOA). METHODS: The study included 127 HOA patients (116 women, mean age 68.6 years (SD 5.8)) with ultrasound, CR and clinical examination of both hands and MRI of dominant hand. Osteophytes were assessed by all imaging modalities on 0-3 scales, whereas clinical bony enlargement was assessed as absent/present. An ultrasound atlas of ostephytes was developed, and the intra and inter-reader reliability of scoring ultrasound osteophytes on still images using the atlas as reference was examined. The reliability for ultrasound readings was examined with κ and percentage exact agreement (PEA) and percentage close agreement (PCA), and the sensitivity, specificity and PEA/PCA of ultrasound was calculated in comparison with MRI, CR and clinical examination. RESULTS: Ultrasound had high sensitivity (0.83) and specificity (0.75) in detecting osteophytes compared with MRI, with excellent PCA (96.1%). Moderate/large osteophytes (grade 2-3) were demonstrated more often by ultrasound (n=401) than by MRI (n=288) in 851 interphalangeal joints. Ultrasound detected more osteophytes (53.2%) than CR (30.0%) and clinical examination (36.9%). Intra and inter-reader reliability of ultrasound was excellent (PEA >88%, PCA 100% and weighted kappa >0.91). CONCLUSION: Ultrasound can reliably assess osteophytes in patients with HOA. Good agreement was found between osteophytes detected by ultrasound and MRI, while ultrasound was more sensitive than CR and clinical examination, which could be due to a multiplanar joint demonstration by ultrasound.

OBJECTIVES: To examine the construct validity of MRI in the detection of structural hand osteoarthritis features with conventional radiography (CR) as reference and explore the association between radiographic severity and MRI-defined pathology. METHODS: 106 hand osteoarthritis patients (97 women, mean age 68.9 years (SD 5.6)) had 1.0T contrast-enhanced MRI and CR of the dominant hand. The 2nd-5th interphalangeal joints were scored according to the preliminary Oslo hand osteoarthritis MRI score and Kellgren-Lawrence (KL) scale and Osteoarthritis Research Society International atlas for radiographs. The authors compared the number of joints with structural features by MRI and CR (Wilcoxon signed-rank test) and examined concordance at the individual joint level. The OR of MRI features in joints with doubtful (KL grade 1), mild (2) and moderate/severe (≥3) radiographic osteoarthritis was estimated by generalised estimating equations (KL grade 0 as reference). RESULTS: MRI detected approximately twice as many joints with erosions and osteophytes compared with CR (p<0.001), but identification of joint space narrowing, cysts and malalignment was similar. The sensitivity of MRI was very high for osteophytes (1.00) and erosions (0.95), while specificity was lower (0.22 and 0.63). The prevalence of most MRI features increased with radiographic severity, but synovitis was more frequent in joints with mild osteoarthritis (OR2.1, 95% CI 1.4 to 3.2) than in moderate/severe osteoarthritis (OR1.4, 95% CI 1.0 to 2.2). CONCLUSION: MRI detected more osteophytes and erosions than CR, suggesting that erosive osteoarthritis may be more common than indicated by CR. Synovitis was most common in mild osteoarthritis. Whether this is due to burn-out of inflammation in late disease must be investigated further.
