Damage to the plantar plates of the metatarsophalangeal joints has been suggested as a cause of forefoot pain and deformity in patients with rheumatoid arthritis (RA). This study looked at 68 plantar plates in patients with RA and forefoot pain using high resolution 3T MRI. Plantar plate pathology was revealed in all patients. However, high signal at the insertion on T2-weighted images (often interpreted as a tear) is not indicative of a tear in patients with RA.
