[Insufficiency fractures of the feet and lower limbs in rheumatoid arthritis]

Insufficiency fractures are generally a rare event, especially of the hindfoot. These are often overlooked in the initial stage, however, they must be regarded as a differential diagnosis in the range of possible causes in patients with rheumatoid arthritis and unclear complaints.

Outpatients in an arthritis care unit from 2009-2011 were analyzed for fractures of the hindfoot and distal tibia.

A total of six patients with seven fractures without adequate trauma were found in the cohort. All patients had received disease modifying therapy and corticosteroids. All fractures could be successfully treated without surgery.

Insufficiency fractures in patients with rheumatoid arthritis are a typical finding after several years of the disease. They are directly related to the disease and medication and can usually be successfully treated conservatively.
