The treatment of Reflex Sympathetic Dystrophy in a 9 year-old boy with long standing symptoms

Reflex sympathetic dystrophy is an uncommonly reported entity in children and it continues to be underdiagnosed. Compared with adult, childhood reflex sympathetic dystrophy is of unknown etiology and has a better prognosis. The most common therapy in children is progressive mobilization supported by antiphlogistic, analgesic drugs, psychological and physical therapy. We report an interesting case of reflex sympathetic dystrophy of the left knee joint of a nine years old child with symptoms insisting more than four years and recalcitrant to the above treatments. The use of intravenous regional anaesthesia with lidocaine 0.5% and methylprednisolone was successful. No other reports seem to exist on the use of lidocaine 0.5% and methylprednisolone for the therapy of reflex sympathetic dystrophy in children. The treatment is simple, safe and well tolerated by children. Psychological factors should not be underestimated. Early diagnosis and aggressive therapy are important factors for the full recovery of the patients.
