Abstract
OBJECTIVES: To investigate the associations of radiographic finger joint osteoarthritis (ROA), hand laterality (right/left) and anatomical location within the hand, with finger joint pain. METHODS: Radiographs of both hands of 295 female dentists and 248 female teachers were examined for the presence of osteoarthritis in each finger joint, using grades 0 = no OA, 1 = doubtful OA, 2 = mild OA, 3 = moderate OA, 4 = severe OA. Information on the occurrence of pain in each finger joint during the past 30 days and hand laterality was obtained by questionnaire. RESULTS: Compared with subjects with no ROA, the prevalence ratio (PR) of finger joint pain was 1.92 [95% confidence interval (CI) 1.61-2.34] among those with mild ROA and 5.34 (4.51-6.54) among those with at least moderate ROA, based on a multivariate log-binomial regression model. Pain was slightly more common in the right than in the left hand (1.27; 1.15-1.40). Compared with the little finger, more pain occurred in the thumb (2.67; 2.25-3.16), the index finger (1.76; 1.50-2.07) and the middle finger (1.47; 1.24-1.74). Further, pain was more common in the proximal interphalangeal (1.77; 1.56-2.00) and the distal interphalangeal (1.51; 1.29-1.76) joints than in the metacarpophalangeal joints. The strength of the association between ROA and finger joint pain increased with the severity of pain. CONCLUSIONS: Our findings suggest that ROA, anatomic localization within the hand, and hand laterality have independent effects on finger joint pain.
