title: [Psoas abscess after anterior spinal fusion].
abstract: We present 3 cases of secondary psoas abscess after anterior spinal fusion. Psoas abscess is still a rare clinical entity. It is often associated with unspecific symptomatology and may present as late infection. A high index of suspicion is required for early diagnosis and treatment. Computed tomography is the imaging technology of choice. Treatment includes open abscess drainage and antibiotic therapy. In secondary psoas abscess causative treatment of the primary infection focus is essential. For psoas abscess after anterior spondylodesis this includes treatment of a deep wound infection. Predisposing factors for postoperative infection are large implants, bone grafting, long operating times, previous spinal surgery, immunodeficiency and metabolic disorders. Usually several operations are necessary to eradicate infection. As long as stability is guaranteed, implant materials should be removed. Continuing antibiotic therapy for 2-3 weeks after normalization of infectious parameters is suggested. Delayed therapy results in an increase of the morbidity and mortality of psoas abscess.
