Anatomy Of The Brachioradialis Muscle - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the anatomy of the Brachioradialis muscle. Origin: the proximal 2/3 of the lateral supracondylar ridge of the humerus. Insertion: the lateral surface of the styloid process of the radius. Innervation: the radial nerve. Function: initiation of pronation, initiation of supination, and flexion of the elbow in mid prone position. The brachioradialis muscle and tendon have an anatomical relationship that is very important and a lot of other features that are clinically significant. The superficial radial nerve runs distally in the forearm under the brachioradialis and lateral to the radial artery. Patient can get Wartenberg syndrome when the superficial radial nerve is compressed by the scissoring effect of the brachioradialis and ECRL tendon during forearm pronation. Cervical radiculopathy of C6 the brachioradialis reflex is affected, so its reflex is C6. The brachioradialis and the wrist extensors have the same root which is C6. So wrist extension and brachioradialis reflex come from C6 from the radial nerve. In C6 we will find: the Brachioradialis reflex is affected with weakness of wrist extension, also there will be paresthesis of the thumb and possibly the index finger. The inverted radial reflex means: tapping of the distal brachioradialis tendon produces ipsilateral finger flexion and it is usually seen when the spinal cord is compressed. The brachioradialis is also important in volar approach to the radius. You reach the radius by the approach between the brachioradialis (radial nerve) and the pronator teres (median nerve) in the proximal forearm. Approach is done between the brachioradialis and flexor carpi radialis in the distal forearm. Be careful of the superficial radial sensory nerve when doing the approach, especially in the distal forearm. The radial nerve lies in the distal humerus between the brachioradialis and the brachialis muscles anteriorly. Approach the radial nerve in the distal humerus between these two muscles. The radial nerve gives three branches before it splits: 1- Brachioradialis. 2- ECRL. 3- ECRB. The brachioradialis is the first muscle to be innervated by the radial nerve, and it is the first muscle to show recovery after injury to the radial nerve. So when you have a radial nerve palsy, you will test the brachioradialis muscle to see if there is any activity or function. Remember: the nerve recover about 1mm per day. If injury to the nerve is at the spiral groove, or at specific location of a fracture, measure the distance between the spiral groove laterally and the brachioradialis, or between the fracture and the brachioradialis. If the distance is 10-12cm then the brachioradialis will show activity approximately after 120 days, which is about 4 months. Just be patient and follow the recovery. If after 4 months there was no recovery of the nerve, then exploration of the radial nerve should be done and possible tendon transfer.
