Summary

We present the second documented case of primary septic arthritis of the talonavicular joint. This patient had a number of medical comorbidities, including chronic widespread pain including the ipsilateral limb, which made diagnosis an even greater challenge. Although a clinical diagnosis, joint fluid aspiration remains the gold standard. Prompt surgical drainage with adjuvant antibiotic treatment is recommended, and management requires a multidisciplinary team approach. The aim of treatment is to avoid the sequelae of joint destruction, pain and foot deformity.
