Reliability of Assessing Hand Osteoarthritis on Digital Photographs and Associations With Radiographic and Clinical Findings.

Marshall M, Jonsson H, Helgadottir GP, Nicholls E, van der Windt D, Myers H, Dziedzic K - Arthritis Care Res (Hoboken) (2014)

Bottom Line: At the joint level, photographic hand OA grade was positively associated with radiographic OA grade (Spearman's ρ = 0.19-0.57, P < 0.001) and the number of clinical features (Spearman's ρ = 0.36-0.59, P < 0.001).At the person level, individuals with higher global photographic OA scores had higher summed K/L scores and higher percentages meeting the American College of Rheumatology clinical hand OA criteria.This photographic scoring system was reliable and a good indicator of hand OA in a separate younger community-dwelling population than the development cohort.

In this study, the associations of photographic hand osteoarthritis (OA) with radiographic OA and clinical features were examined to explore the construct validity of hand photography as an indicator of hand OA. An example of a hand photograph and its corresponding radiographic image is shown.

fig01: In this study, the associations of photographic hand osteoarthritis (OA) with radiographic OA and clinical features were examined to explore the construct validity of hand photography as an indicator of hand OA. An example of a hand photograph and its corresponding radiographic image is shown.

Mentions: The associations of photographic hand OA with radiographic OA and clinical features were examined to explore the construct validity of hand photography as an indicator of hand OA (example in Figure 1). For each hand joint and joint group, the frequency of 1) mild (K/L score of 2) and moderate to severe (K/L score ≥3) radiographic OA and 2) the number of clinical features present on the hand examination were determined for each photographic hand OA grade (range 0–3). The radiographic grade and numbers of clinical features for a joint group were determined by the highest radiographic grade and greatest number of clinical features that were present in any of the joints within a group, respectively. Spearman's rank correlation coefficients were calculated to assess the strength and statistical significance of associations of photographic hand OA score with radiographic OA and clinical features at the joint and joint group level. Additionally, global hand OA scores (range 0–9) were compared at the person level using descriptive statistics to 1) summed K/L radiographic scores for all 10 hand joints divided into quartiles and 2) the presence of clinical hand OA according to the ACR criteria (where hand pain was present on most or all days) (7), relaxed ACR criteria (where hand pain was present on some, most, or all days), and the clinical features of hand OA using the ACR criteria (not including the presence of hand pain).
