Brachioradialis

Dr Jeremy Jones et al.

Brachioradialis is a flexor at the elbow and works with biceps brachii and brachialis. Is it located in the superficial layer of the posterior compartment of the forearm and is particularly useful in elbow stabilisation.

Despite the bulk of the muscle being visible from the anterior surface of the forearm, it is a posterior compartment muscle and thus, its innervation derives from the posterior compartment. It is one of the three muscles forming the mobile wad of Henry.

Summary

  • origin: proximal 2/3 of lateral supracondylar ridge of humerus
  • insertion: lateral surface of distal end of radius just proximal to styloid process of radius.
  • innervation: radial nerve (C5, C6)
  • action: flexor of the elbow with particular use in stabilisation
