Roseomonas gilardii rarely causes infection in humans. We report that a patient with underlying rheumatoid arthritis and diabetes developed wrist septic arthritis and osteomyelitis due to Roseomonas after steroid joint injection. After antibiotic and surgical treatment, the condition of the patient improved. We reviewed previously reported cases of soft tissue, joint and bone infection related to Roseomonas to understand the characteristics of joint and bone infection of Roseomonas.
