Obturator internus pyomyositis: iatrogenic haematogenous spread.

Abstract

Obturator internus pyomyositis is a rare disorder that should be on the differential diagnosis in a child who presents with a fever, limp, abdominal or groin pain. We present a case of a 5-year-old girl successfully treated with open drainage following failed medical management. We postulate the source of infection to be secondary to an infected elastic stable intramedullary nail in the forearm that was protruding through the skin.
