RESUMEN
Base on the clinical characteristics of septic arthritis in a group of systemic lupus erythematosus patients,this study has found out that high systemic lupus erythematosus disease activity index,leucopenia,high cumulative dose of glucocorticoid,methylprednisolone intravenous pulse therapy and joint cavity puncture were closely correlated with septic arthritis.Once septic arthritis is suspected,culture specimens should be collected and appropriate antibiotics are suggested immediately.Also,surgical drainage is a very useful approach.
RESUMEN
We report a case of delayed diagnosis of osteomyelitis of the scapula extending to glenoid, with secondary septic arthritis of glenohumeral joint in a 6-month-old female infant. We performed urgent arthrotomy of the shoulder joint through an anterior approach with drainage of pus from the scapula through a posterior approach and prescribed intravenous antibiotics. Diagnosis was delayed as the patient initially presented with pneumonia, for which she was treated in the neonatal intensive care unit; at that time, all medical efforts were directed toward saving her life. Had the diagnosis been made earlier, septic arthritis of the shoulder might have been prevented. Diagnosis of septic shoulder arthritis is rare and difficult, requiring a high index of suspicion.
