- W2051205620 abstract "Infections of the vertebral column can result in ver tebral osteomyelitis with or without epidural abscess. Moreover, spontaneous infection arising from the epidu ral space can occur, leading to epidural abscess. Whether these infections arise spontaneously or postoperatively, they can progress rapidly and cause severe neurologi cal deficits. Despite the wide availability of intravenous antibiotics and advanced surgical techniques in recent decades, vertebral osteomyelitis and epidural abscess re main problematic and are major causes of debilitating neurological injury and morbidity. Appropriate treat ment of vertebral osteomyelitis and epidural abscess is essential to prevent calamitous consequences, including paralysis and death. Physicians and practitioners should first be aware of the natural history and risk factors associated with these diseases to perform appropriate diagnostic modalities. Speedy and accurate diagnosis is the first essential step to direct timely treatments. Although vertebral osteomyelitis and epidural abscess are considered to be rare historically, their incidence appears to be increasing in recent years compared with that in the first half of the 20th century.2 This disparity in epidemiology results from a number of factors, including improved neuroimaging capabilities, better awareness of these diseases, an increased number of elderly individuals, and a greater number of immuno compromised patients, from cancer survivors to individu als with human immunodeficiency virus (HIV) infection. At the same time, there is a growing rate of illicit drug abuse in the United States as well as a greater incidence of methicillinresistant Staphylococcus aureus infections. Despite having sophisticated imaging techniques and labo ratory studies, the rate of misdiagnosis at presentation for vertebral osteomyelitis and epidural abscess is still high, with an average rate of approximately 50%.3,5,7 Symptomatic vertebral osteomyelitis and epidural abscess with neurological deficits have long been con sidered surgical emergencies. The goal of surgery is to provide direct decompression of spinal cord and nerves to prevent neurological deterioration and reverse neu rological deficits. Since local inflammation leading to thrombophlebitis or venous congestion is thought to be the mechanism of neurological injury in some cases, sur gical debridement can also remove the inciting organisms and factors to reduce the risk of vascularrelated neuro logical complications. On the other hand, the treatment of neurologically intact patients with vertebral osteomyelitis alone or minimal epidural abscess is quite controversial. Successful medical treatment for these types of cases has been reported, as have cases of failed medical treat ment resulting in neurological decline.1,3,4,6,8 The scarcity of these cases along with the wide variation in clinical presentations makes it difficult to conduct any largescale observational studies. Furthermore, conducting a randomized study of treatment in these diseases raises ethical concerns because of the potential for progressive and devastating outcomes with the failure of treatment. Hence, physicians are largely dependent on anecdotal ex perience, animal studies, literature case reports, and un controlled clinical series to gain knowledge and treatment guidance for vertebral osteomyelitis and epidural abscess. In this issue of Neurosurgical Focus, articles on the diagnosis, medical management, surgical treatment, and clinical outcomes related to vertebral osteomyelitis and spinal epidural abscess are included. We hope that read ers will find pertinent information on the management of vertebral osteomyelitis and spinal epidural abscess from the articles in this issue.
