Abstract

Objective: We aimed to determine whether hand joints develop an accelerated form of osteoarthritis (OA) and to characterize individuals who develop accelerated hand osteoarthritis (AHOA).

Methods: We evaluated 3519 participants in the Osteoarthritis Initiative with complete data for baseline and 48-month radiographic hand osteoarthritis (HOA). One reader scored posteroanterior radiographs of the dominant hand using a modified Kellgren-Lawrence (KL) scale and another reader scored the presence of central or marginal erosions. A third reader read images flagged for signs of diseases other than OA. We defined AHOA as ≥ 1 joints that progressed from a KL grade of 0 or 1 at baseline to KL grade 3 or 4 at 48 months.

Results: The definition of AHOA was met by 1% over 4 years: 37 hands had 1 joint affected and 1 hand had 2 joints affected. At baseline, adults who developed AHOA were more likely to have hand pain (37% vs 22%), radiographic HOA (71% vs 36%), as well as central (22% vs 7%) and marginal erosions (11% vs 2%) in other joints compared to those without AHOA. Adults with AHOA were more likely to develop new erosions over 48 months (central 35%, marginal 5%) than those without AHOA (central 5%, marginal 1%). The most common locations of accelerated OA were the second metacarpophalangeal and first carpometacarpal joint.

Conclusion: Accelerated OA can occur in the hand, especially among digits commonly used for pinching and fine motor skills.
