As its name suggests the Brachioradialis is related to the radius. Anatomically the origin is at Upper two-thirds of anterior aspect of lateral supracondylar ridge of humerus (i.e. lateral part of shaft of humerus, 5–7.5 cm (2–3”) above elbow joint). It inserts in to the lower end or the radius just above the styloid process. Problems with trigger points in the Brachioradialis muscle often present classically as pain in the thumb on shaking hands, pain in the elbow and weakness of grip. Because it is a wrist extensor, it can often become involved in extensor overuse syndromes.
The brachioradialis is part of the superficial muscle group and forms the lateral border of the cubital fossa. The muscle belly is prominent when working against resistance. It is often worth looking for trigger points in the triceps muscle if there is a longstanding issue in the Brachioradialis muscle. A classic presentation of Brachioradialis trigger points is thumb pain in people who shake a lot of hands – this is sometimes called politicians thumb.
