Within the recent years more research have focused on IMB in patients with rheumatologic disorders. There is emerging evidence that IMB is an inflammatory alteration in line with synovitis in patients with RA, and presence of IMB have been linked to the early stages of RA, especially due to the focus of the published literature.~The clinical implications of the presence of IMB for the patients are yet to be understood. Limited studies have linked the occurrence of IMB to foot impairment, but no studies have been conducted investigating the direct association between forefoot pain and the presence/absence of IMB.
The aim of the study is to investigate the incidence and clinical implications of intermetatarsal bursitis (IMB) in patients with rheumatoid arthritis (RA).~The hypothesis is that IMB is a cause of pain in patients with RA.
