Acute osteomyelitis

Osteomyelitis is a complex disease, and a number of classification systems have emerged, e.g. the Waldvogel system, which divides osteomyelitis into hematogenous, contiguous and chronic (Carek, Dickerson and Sack, 2001, 2413). In this system, contiguous osteomyelitis is secondary to a contiguous focus of infection and either has no generalized vascular disease, or there is generalized vascular disease present. Chronic osteomyelitis in this system has necrotic bone. The newer Cierny-Mader classification system is based on the disease status, not its chronicity, etiology, or other factors. The terms "acute" and "chronic are not used in this system, and the stages are dynamic, changing with the patient's medical condition, successful antibiotic treatment, and other treatments. There may be special circumstances under which neith

hargy, and irritability (Carek, Dickerson and Sack, 2001). There is tenderness over the bone and a decreased range of motion in the adjacent joints, and there may be drainage at the local area of the infection if an injury has occurred. Subacute and chronic forms are usually secondary to an open wound, and cause localized bone pain, erythema, and drainage at the affected area. The standard signs of subacute and chronic osteomyelitis are draining sinus tracts, deformity, instability, and local signs of impaired vascularity, range of motion and neurological status. Deep musculoskeletal infections associated with fractures can occur. In vertebral osteomyelitis, patients can experience pain in the chest, abdomen, arm, or leg because inflammation in the spine puts pressure on nerve roots serving these areas (Carson-DeWitt, 2001). When the infection interferes with blood flow to a part of the bone, the bone served by those blood vessels will die. Acute osteomyelitis involves infection of the periosteum, and/or the medullary cavity (Cunha, 2002). It may be acquired hematogenously after closed trauma, with the bacteria reaching the metaphyseal blood vessels of the bone and initiating the infection process. Bacteria in the smal
