Pyomyositis of the obturator internus muscle extending to septic arthritis of the hip in a child: a case reportAmari, Rui; Yokoi, HiromichiJournal of Pediatric Orthopaedics B: January 2014 - Volume 23 - Issue 1 - p 55–58 doi: 10.1097/BPB.0b013e328365295d HIP Buy Abstract Author InformationAuthors Article MetricsMetrics We report a case of primary pyomyositis in the obturator internus muscle. Pyomyositis involving muscles around the hip needs to be differentiated from septic arthritis because these infections show similar symptoms. Management with antibiotics can avoid the need for surgical intervention. Uncontrolled pyomyosistis can cause sequelae such as septic shock, osteomyelitis of adjacent bone, and septic arthritis. Awareness of this condition will facilitate correct diagnosis and early treatment.
