Is radiography sensitive for the detection of acute osteomyelitis in the early clinical setting? No. The radiographic findings of acute osteomyelitis take time to develop, typically 1 to 2 weeks, although this depends on the severity of the infection. Therefore, radiographic findings may not be present in early or very low-grade infections.
What differential diagnoses may simulate the appearance of acute osteomyelitis on radiographs? Traumatic changes and postsurgical findings are the most common mimickers of osteomyelitis on radiographs. In particular, healing fractures result in periosteal reaction, and surgical defects can simulate the appearance of osteolysis. Comparison studies, and in particular, accurate and pertinent clinical history, can obviate …
What is the most specific finding of acute osteomyelitis on radiographs? Osseous destruction subjacent to a soft tissue ulcer.
What are the primary findings of acute osteomyelitis on radiographs? Bone destruction (osteolysis), osteopenia, and periosteal reaction, particularly if located adjacent to a soft tissue ulcer
What is the role of nuclear medicine techniques in the diagnosis of musculoskeletal infection? Technetium-99m ( 99m Tc) methylene diphosphonate (MDP) bone scintigraphy (“bone scan”), Indium-111 ( 111 In) white blood cell (WBC) scintigraphy (“WBC scan”), and fluorine-18 ( 18 F)-fluorodeoxyglucose (FDG) positron emission tomography (PET) are available nuclear medicine techniques that can be used to diagnose musculoskeletal infection. Currently, their …

Clinical significance of an abscess Abscesses are difficult to treat with antimicrobial agents alone, particularly when large in size. They often require drainage for complete treatment. In contradistinction, a phlegmon cannot be drained (because it does not contain an organized pocket of fluid) and therefore is generally treated with antimicrobial agents alone.
what is the first line imaging modality used to diagnose musculoskeletal infection? Radiography. It is fast, inexpensive, and frequently the only imaging modality necessary to establish a diagnosis of infection.
