Glenohumeral joint effusion assessment with point-of-care ultrasound.

Ultrasound has favorable diagnostic accuracy for detecting glenohumeral joint effusions. This article describes an easy-to-learn and interpret limited glenohumeral joint ultrasound examination that can help guide further evaluation and treatment. We report on a patient ultimately diagnosed with septic arthritis of the glenohumeral joint, the associated joint effusion having been detected on bedside ultrasound. This ultrasound examination is applicable to generalist PAs and those working in orthopedics and acute care settings.
