[Multiple osteo-articular involvement due to methicillin-resistant Staphylococcus aureus septicaemia: clinical and therapeutic evaluation]

Here we report a rare case of septic spondilodiskitis by methicillin-resistant Staphylococcus aureus, complicated by the atypical involvement of two articular sites such as manubrio-clavicular joints and right wrist. The source of the septic process was identified in hand's eczematous lesions and paronychia. A first therapeutical attempt performed by combining teicoplanin with netilmicin or rifampicin was useless. A new course with vancomycin instead of teicoplanin favoured the prompt remission of symptoms. Following 10 weeks of continuous treatment, we observed the complete disappearance of all radiological signs of vertebral damage. Though rarely, polyarthritis may complicate a Staphylococcus aureus bacteraemia. An adequate chemio-antibiotic course may lead to definitive recovery and avoid surgery.
