Upper and Lower Extremities

Advances in computed tomography (CT) technology over the past decade and the increasing availability of the modality, particularly in emergency room (ER) departments, have resulted in increased use of CT for musculoskeletal imaging. Radiographs remain the primary modality for diagnosing fractures, monitoring progress of healing, assessing for hardware complications, and for initial evaluation of the majority of musculoskeletal complaints. However, CT is a valuable tool for further fracture characterization and treatment planning, detection of radiographically occult fractures, visualization of the degree of union about an arthrodesis or fracture, and diagnosis of hardware related complications. Recent advances have shown utility for early detection of crystal load in gout and in guidance for radiofrequency ablation of osteoid osteoma.
