Ultrasonography for the Busy Orthopaedic Surgeon: The Lower Extremity.

Ultrasonography has the potential to become a fundamental component of the diagnosis and management of musculoskeletal conditions and injuries. Moreover, in the context of modern healthcare systems that are focused on optimizing value, ultrasonography has the advantage of minimizing costs when compared with other advanced imaging modalities. Because of its low cost, lack of radiation exposure, speed, and capability to diagnose dynamic conditions, more orthopaedic surgeons are routinely integrating musculoskeletal ultrasonography into their daily practice. It is important to provide a comprehensive review of and approach to common musculoskeletal conditions of the lower extremity for the busy orthopaedic surgeon.
