Abstract

Purpose: An atlas for grading hand osteoarthritis (OA) on photographs has been shown to be reliable and associated with clinical examination and radiographic features in a population of older adults (aged ≥69 years) from the AGES-Reykjavik study. The objective of this research was to determine if this atlas was reliable and to assess its association with radiographic and clinical features in a different younger community-dwelling population.

Methods: Participants were community-dwelling older adults (≥50 years) in North Staffordshire, UK with self-reported hand pain or hand problems in the last year who attended a research clinic. High quality photographs taken at a set distance in a standardised position were graded for the presence of hand OA using an established atlas. Hand radiographs were graded for OA using the Kellgren Lawrence grading system and the presence of clinical features (nodes, bony enlargement, deformity) was determined on physical examination by trained assessors.

Results: Following exclusions 558 participants (mean age 64 years, 62% female) were included in the analyses. Overall reliability for scoring each joint and joint group was good (mean intra-rater ICC =0.79, mean inter-rater ICC =0.71). For each joint and joint group photographic hand OA was positively associated with grade of radiographic OA (rho 0.19-0.57, p<0.001) and the number of clinical features present on an examination (rho 0.36-0.59, p<0.001). At the person level, individuals with higher global photographic hand OA scores had higher summed K&L scores and had higher percentages meeting the ACR clinical hand OA criteria.

Conclusions: This photographic scoring system for hand OA has been shown to be reliable and associated with both radiographic and clinical features in a different and younger community-dwelling population to that in which it was developed. This method of data collection offers researchers an feasible alternative to the physical examination and maybe of particular use to large studies and those spread over a wide geographic areas.
