Osteoarthritis

Hand joints without radiographic osteoarthritis maintain their joint space width over 4 years despite what’s happening elsewhere in the hand

Rheumatology (Oxford)Published Cohort study

Authors' conclusion

Hand OA is not a systemic disease of cartilage.

Study context

Population
Osteoarthritis Initiative participants with baseline and 48-month hand radiographs; distal and proximal IP joints
Participants
3,368 participants
Exposure
Radiographically normal joints in hands with incident or prevalent hand OA vs hands without OA
  • No hand OAn = 1,054reference
  • Incident hand OAn = 102
  • Prevalent hand OAn = 2,212
Outcome
JSW loss in radiographically normal (KL 0) joints
Follow-up
4 years
Methodological detailslongitudinal, semi-automated joint space width (JSW) measurement, unpooled effect sizes
  • Longitudinal
  • Semi-automated JSW measurement
  • Unpooled effect sizes

Main finding

As reported in the abstract

JSW loss in radiographically normal joints

Small differences in JSW loss, unlikely to be clinically important, between no hand OA and incident or prevalent hand OA (effect size range)

−0.01-0.24

Observational data: associations, not effects.

Further findings

JSW loss dichotomized on meaningful change and other secondary analyses

Findings robust
