BackgroundOsteitis of the posterior wall of the spinal canal is an exceptional complication after peridural anesthesia. Prognosis depends on early diagnosis based on clinical signs and imaging data.Case ReportA 73-year-old man was hospitalized for lower back pain and fever of 3 weeks duration after a total hip arthroplasty performed under general anesthesia. Computed tomography and magnetic resonance imaging of the lumbar spine disclosed osteitis of the spinal processes. Local bacteriology sample evidenced Pseudomonas aeruginosa. Outcome was favorable after a 6-month treatment.DiscussionData in the French and English literature (since 1948) on bone infections following epidural anesthesia have included 5 cases of spondylodiscitis and 1 case of posterior wall osteitis. The diagnosis is suggested by the clinical presentation. Standard x-rays contribute little. Early diagnosis in the infraradiological phase can be obtained with bone scintigraphy. Computed tomography or magnetic resonance imaging are currently highly contributive to diagnosis and follow-up after treatment. Contamination may be direct or via the blood stream or result from an extension of a neighboring infectious focus. Antibiotic therapy and immobilization are indicated. Rigorous application of strict aseptic procedures during lumbar puncture and use of the epidural catheter are crucial for prevention.
