Video: Musculoskeletal ultrasound imaging of the elbow: part 2, Pathology.

OBJECTIVE: The purpose of this video article is to aid examiners in clinical practice in identifying intraarticular and extraarticular pathologic changes in the elbow, including intraarticular structures, fluid in the joint, arthritis, synovitis, and loose bodies.

CONCLUSION: Common pathologic findings can be identified with a standardized ultrasound technique based on landmarks, and intraarticular injection and aspiration, dynamic imaging, and ulnar stress maneuvers can be performed. Extraarticular pathologic findings are evaluated in an approach based on quadrants.
