Clinical history |
|---|
A 25 year old carpenter presented with a two day history of intense pain in the left ankle. The pain started suddenly when he injured the ankle while working in the joinery, and had been getting steadily worse ever since. The patient was known to suffer from a chronic haematological disorder, and had previously experienced multiple similar episodes affecting in particular the left ankle and right knee joints, often following minor trauma.
On examination he held the ankle dorsiflexed and was unable to weight bear. Movement was limited in all directions. The ankle appeared swollen and was exquisitely tender to palpation. Examination was otherwise normal. The patient was apyrexial. Serological tests (rheumatoid factor, erythrocyte sedimentation rate, C reactive protein) were negative. Plain radiographs and magnetic resonance images of the knee and ankle joints were obtained.
