[Infection of the hip joint following psoas abscess. Case report and literature review].

Infection of the hip joint following psoas abscess is uncommon. In fact, only two cases have been reported in the literature. The clinical aspect of psoas abscess is characterised only by unspecific back pain and hip pain, which are responsible for delayed diagnosis. MRT and culture of joint aspirate can permit early diagnosis. The preferred treatment is immediate surgical intervention with debridement, drainage and antibiotic therapy. Percutaneous drainage of psoas abscess alone only rarely is sufficient. In cases of infected hip joint, resection arthroplasty often cannot be avoided. Following complete decline of inflammatory parameters and certain absence of bacteria confirmed by repeated joint aspiration, prosthetic joint replacement is possible. This decision should be made on an individual basis, because Girdlestone hip also can lead to a satisfactory result concerning pain relief and functional outcome.
