Answer

The elbow is held in 90° flexion. The olecranon process, the lateral epicondyle, and the radial head are palpated. The needle is then inserted laterally into the triangle formed by these three structures. (See the image below.)

Approach to aspiration of elbow joint, with landma Approach to aspiration of elbow joint, with landmarks labeled. LE = lateral epicondyle; R = radial head; O = olecranon.
