Musculoskeletal - Posterior Elbow Joint Injection
Caption
92 y/o M presented with moderate to severe osteoarthritis on elbow x-ray who was treated with ultrasound-guided corticosteroid joint injection. Video shows transverse view of the posterior elbow as corticosteroid is injected with a posterolateral approach deep to the posterior elbow fat pad located in the olecranon fossa. This area is continuous with the elbow joint capsule. Posterolateral approach is advantageous due to decreased risk of disrupting neurovascular structures or the articular cartilage from other approaches to the joint space. Posterior approach is also advantageous compared to lateral approach in moderate to severe arthritis due to limited access to the radiocapitellar joint space.
