Obturator internus muscle (OIM) abscess is an uncommon condition often mistaken for bacterial infection of the hip joint. If the OIM abscess is accompanied by a septic hip, it becomes more difficult to make a diagnosis. Surgical drainage of OIM abscess is difficult because it is located at a deep part of the pelvic cavity. Therefore, intravenous antibiotic therapy or image-guided aspiration were used as a treatment method instead of surgical drainage. When drainage of the abscess was inadequate, prolonged antibiotic treatment was necessary. Here, we report a 12-year boy with abscess in the OIM and ipsilateral pyogenic arthritis of the hip which was accompanied by acute osteomyelitis of the triradiate cartilage of the acetabulum. The patient was successfully treated by surgical drainage of the abscess using the Stoppa approach and arthroscopic irrigation of the hip joint. Staphylococcus aureuswas the causative organism which was sensitive to oxacillin.
闭孔内肌（OIM）脓肿是一种罕见病症，常被误诊为髋关节细菌感染。如果OIM脓肿伴有化脓性髋关节炎，诊断就会更加困难。由于OIM脓肿位于盆腔深部，对其进行手术引流很困难。因此，静脉注射抗生素治疗或影像引导下穿刺抽吸被用作替代手术引流的治疗方法。当脓肿引流不充分时，需要延长抗生素治疗时间。在此，我们报告一名12岁男孩，患有OIM脓肿及同侧髋关节化脓性关节炎，并伴有髋臼三辐射软骨急性骨髓炎。采用Stoppa入路对脓肿进行手术引流并对髋关节进行关节镜冲洗，成功治愈了该患者。金黄色葡萄球菌是病原体，对苯唑西林敏感。
