Abstract

Although distal tibial oblique osteotomy (DTOO) has usually been indicated for non-inflammatory diseases such as osteoarthritis, we encountered three patients with rheumatoid arthritis (RA) who underwent DTOO. We evaluated radiographic parameters and clinical scores, including self-reported scores for the foot and ankle (SAFE-Q) and the Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot scale. In all three cases, radiographic improvements were achieved along with improvements in SAFE-Q and JSSF scores after mid-term follow-up. Supramalleolar osteotomy including DTOO could be indicated even for inflammatory diseases such as RA, if erosive changes are not evident in the ankle joint.

Keywords: ankle joint; distal tibial oblique osteotomy (DTOO); erosive/ destructive change; rheumatoid arthritis (RA).
