Radiographic scoring methods in hand osteoarthritis - a systematic literature search and descriptive review

OBJECTIVE\nThis systematic literature review aimed to evaluate the use of conventional radiography (CR) in hand osteoarthritis (OA) and to assess the metric properties of the different radiographic scoring methods.\nDESIGN\nMedical literature databases up to November 2013 were systematically reviewed for studies reporting on radiographic scoring of structural damage in hand OA. The use and metric properties of the scoring methods, including discrimination (reliability, sensitivity to change), feasibility and validity, were evaluated.\nRESULTS\nOf the 48 included studies, 10 provided data on reliability, 11 on sensitivity to change, four on feasibility and 36 on validity of radiographic scoring methods. Thirteen different scoring methods have been used in studies evaluating radiographic hand OA. The number of examined joints differed extensively and the obtained scores were analyzed in various ways. The reliability of the assessed radiographic scoring methods was good for all evaluated scoring methods, for both cross-sectional and longitudinal radiographic scoring. The responsiveness to change was similar for all evaluated scoring methods. There were no major differences in feasibility between the evaluated scoring methods, although the evidence was limited. There was limited knowledge about the validity of radiographic OA findings compared with clinical nodules and deformities, whereas there was better evidence for an association between radiographic findings and symptoms and hand function.\nCONCLUSIONS\nSeveral radiographic scoring methods are used in hand OA literature. To enhance comparability across studies in hand OA, consensus has to be reached on a preferred scoring method, the examined joints and the used presentation of data.Pathophysiology and treatment of rheumatic disease

Can gait patterns be explained by joint structure in people with and without radiographic knee osteoarthritis?: Data from the IMI-APPROACH cohort

Objective To determine the association between joint structure and gait in patients with knee osteoarthritis (OA). Methods IMI-APPROACH recruited 297 clinical knee OA patients. Gait data was collected (GaitSmart®) and OA-related joint measures determined from knee radiographs (KIDA) and MRIs (qMRI/MOAKS). Patients were divided into those with/without radiographic OA (ROA). Principal component analyses (PCA) were performed on gait parameters; linear regression models were used to evaluate whether image-based structural and demographic parameters were associated with gait principal components. Results Two hundred seventy-one patients (age median 68.0, BMI 27.0, 77% female) could be analyzed; 149 (55%) had ROA. PCA identifed two components: upper leg (primarily walking speed, stride duration, hip range of motion [ROM], thigh ROM) and lower leg (calf ROM, knee ROM in swing and stance phases). Increased age, BMI, and radiographic subchondral bone density (sclerosis), decreased radiographic varus angle deviation, and female sex were statistically signifcantly associated with worse lower leg gait (i.e. reduced ROM) in patients without ROA (R2=0.24); in ROA patients, increased BMI, radiographic osteophytes, MRI meniscal extrusion and female sex showed signifcantly worse lower leg gait (R2=0.18). Higher BMI was signifcantly associated with reduced upper leg function for non-ROA patients (R2=0.05); ROA patients with male sex, higher BMI and less MRI synovitis showed signifcantly worse upper leg gait (R2=0.12). Conclusion Structural OA pathology was signifcantly associated with gait in patients with clinical knee OA, though BMI may be more important. While associations were not strong, these results provide a signifcant association between OA symptoms (gait) and joint structure.Pathophysiology and treatment of rheumatic disease

Development of classification criteria for hand osteoarthritis: comparative analyses of persons with and without hand osteoarthritis

Objectives Further knowledge about typical hand osteoarthritis (OA) characteristics is needed for the development of new classification criteria for hand OA.Methods In a cross-sectional multi-centre international study, a convenience sample of patients from primary and secondary/tertiary care with a physician-based hand OA diagnosis (n = 128) were compared with controls with hand complaints due to inflammatory or non-inflammatory conditions (n = 70). We examined whether self-reported, clinical, radiographic and laboratory findings were associated with hand OA using logistic regression analyses. Discrimination between groups was assessed by calculating the area under receiver operating curves (AUC).Results Strong associations with hand OA were observed for radiographic osteophytes (OR = 1.62, 95% CI 1.40 to 1.88) and joint space narrowing (JSN) (OR = 1.57, 95% CI 1.36 to 1.82) in the distal interphalangeal (DIP) joints with excellent discrimination (AUC = 0.82 for both). For osteophytes and JSN, we found acceptable discrimination between groups in the proximal interphalangeal joints (AUC = 0.77 and 0.78, respectively), but poorer discrimination in the first carpometacarpal joints (AUC = 0.67 and 0.63, respectively). Painful DIP joints were associated with hand OA, but were less able to discriminate between groups (AUC = 0.67). Age and family history of OA were positively associated with hand OA, whereas negative associations were found for pain, stiffness and soft tissue swelling in metacarpophalangeal joints, pain and marginal erosions in wrists, longer morning stiffness, inflammatory biomarkers and autoantibodies.Conclusions Differences in symptoms, clinical findings, radiographic changes and laboratory tests were found in patients with hand OA versus controls. Radiographic OA features, especially in DIP joints, were best suited to discriminate between groups.Clinical epidemiolog

Prolonged morning stiffness is common in hand OA and does not preclude a diagnosis of hand osteoarthritis

Objective: Prolonged morning stiffness (>60 min) is considered a symptom of inflammatory arthritis, but has a poor discriminative ability. Knowledge about morning stiffness in patients with hand osteoarthritis (OA) is lacking. We therefore studied morning stiffness in patients with hand OA. Design: Patients with primary hand OA according to their treating rheumatologist in the Hand OSTeo-Arthritis in Secondary care (HOSTAS) cohort were studied. Severity of morning stiffness was examined with Australian/Canadian hand OA index (AUSCAN) and presence and duration of morning stiffness were examined with a standardized questionnaire. Association of patient and disease characteristics with prolonged morning stiffness (>60 min) were analyzed with logistic regression. Results: In total 519 of 538 patients had available data about duration of morning stiffness, of whom 89 (17%) had prolonged morning stiffness. Severity of stiffness was mild in 158 of 525 (30%), intermediate in 194 (37%), severe in 97 (18%) and extreme in 19 (4%) patients. Patients with prolonged morning stiffness reported more pain, worse physical function and had a reduced mental and physical quality of life. Patients with prolonged morning stiffness also had more severe radiographic disease, although the association did not reach statistical significance. Conclusions: Prolonged and severe morning stiffness are frequently present in patients with hand OA. Patients with these symptoms report more pain in general and have a lower quality of life than patients that do not report these symptoms. Prolonged morning stiffness does not preclude a diagnosis of hand OA. (c) 2022 The Authors. Published by Elsevier Ltd on behalf of Osteoarthritis Research Society International.
