Elbow joint injection. A. Transducer and needle positioning for simulated elbow joint injection. B. On a longitudinal US scan, the humeroradial joint is depicted underneath the common extensor tendon (Comm Ext T). A 21-gauge needle (arrow) is inserted into the joint using an out-of-plane approach

Olecranon bursitis aspiration. Fluid and synovial hypertrophy (asterisk) are seen within the inflamed olecranon bursa. A. An 18-gauge needle (arrows) is inserted into the bursa using an in-plane approach and fluid is aspirated for diagnostic purposes

Common extensor tendon dry needling. A. Transducer and needle positioning for simulated common extensor tendon dry needling. B. The common extensor tendon (Comm Ext T) is thickened and degenerated at its attachment to the lateral epicondyle. A 21-gauge needle (arrows) is inserted into the degenerated areas of the tendon using an in-plane distal-to-proximal approach, and repeated punctures are performed

Radiocarpal joint injection. A. Transducer and needle positioning for simulated radiocarpal joint injection. B. On a longitudinal scan, the radiocarpal dorsal recess is thickened (asterisks) in a rheumatoid arthritis patient. A 25-gauge needle (arrow) is inserted into the joint using an out-of-plane approach to perform joint injection

De Quervain’s tenosynovitis injection. A. Transducer and needle positioning for simulated De Quervain’s tenosynovitis injection. B. On an axial US scan, the abductor pollicis longus (Abd pl) and extensor pollicis brevis (Ext pb) tendons are thickened and rounded due to tendinosis. The extensor retinaculum forming the roof of the I extensor compartment (asterisks) is thickened. A 25-gauge needle (arrow) is inserted underneath the retinaculum using an in-plane lateral-to-medial approach

Trigger finger injection. A. Transducer and needle positioning for simulated trigger finger injection. B. At the level of the metacarpal head (Met), the flexor tendons (Flex) are shown, and the A1 pulley (asterisks) is thickened. A 25-gauge needle (arrows) is inserted underneath the pulley using an in-plane axial approach
