Focus on POCUS Point of Care Ultrasound in the Upper Extremity.

Ultrasound technologies are infrequently utilized in orthopedics as a first line diagnostic method, however, advances in technology and the applied techniques have opened the door for how and when ultrasound can be used. One specific avenue is the use of point of care ultrasound in which ultrasound is used at the time of initial patient evaluation by the evaluating physician. This use expedites time to diagnosis and can even guide therapeutic interventions. In the past two decades there have been numerous studies demonstrating the effectiveness of ultrasound for the diagnosis of many orthopedic conditions in the upper extremity, often demonstrating that it can be used in the place of and with greater diagnostic accuracy than magnetic resonance imaging. This review elaborates on these topics and lays a groundwork for how to incorporate point of care ultrasound into a modern orthopedic practice.
