摘要
Background: Identification of fluid in the elbow joint by physical examination alone can be challenging. Ultrasound can assist in the diagnosis of elbow effusion, and guide aspiration of the effusion. Objectives: We illustrate the anatomy and ultrasound guidance technique of a posterior approach to elbow arthrocentesis using examples of normal and pathologic elbow joint ultrasound images. Discussion: The posterior distal humerus at the level of the olecranon fossa provides an excellent acoustic window into the joint space. This location also provides a safe path for the performance of ultrasound-guided arthrocentesis. Conclusion: Ultrasound-guided arthrocentesis of the elbow from a posterior approach is a helpful technique to guide the aspiration of the painful swollen elbow.
