Imaging of the musculoskeletal system

Musculoskeletal (MSK) plain film radiography remains an integral part of MSK imaging especially in emergency medicine and its interpretation is an important skill to learn. Other imaging modalities are being utilised increasingly to complement plain films in the investigation of musculoskeletal pathology.In this article musculoskeletal disease is discussed under the headings of trauma, infection, neoplastic disease, arthritis and metabolic bone disease. The various imaging modalities including their strengths and weaknesses are discussed. Emphasis is placed on the imaging modalities most appropriate in specific clinical settings and key radiological findings are described and examples included.
