Tennis Elbow Muscle (ECRB) - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the anatomy of the extensor carpi radialis brevis muscle (ECRB).
Lateral side of elbow:
- The muscle that is involved in the condition of tennis elbow is the extensor carpi radialis brevis muscle.
- This muscle is an important muscle although its name suggests it is small and not important.
- The ECRB muscle originates from the lateral epicondyle of the humerus (commin extensor tendon).
- The ERCB muscle is inserted into the base of the dorsal aspect of the 3rd metacarpal.
The ERCB muscle gets its nerve supply from the radial nerve.
The function of the ERCB is to extend and abduct the hand at the wrist joint.
The ERCB is located in the 2nd dorsal compartment on the radial side of the lister’s tubercle.
Some conditions associated with the ECRB muscle:
1- Tennis elbow: (lateral epicondyle) is an overuse injury that causes inflammation, tendinosis and lateral elbow pain at the origin of the ECRB tendon.
The pathology of the ECRB tendon in tennis elbow shows disorganized collagen, vascular hyperplasia and fibroblast hypertrophy.
Treatment is usually given with rest, therapy, injection or surgery as a last resort.
2- Intersection syndrome: the pain from intersection syndrome is felt in the top of the forearm, where two muscles that connect to the thumb cross over the underlying wrist tendon.
Inflammation of the ECRL/ECRB as they intersect with the APL and the EPB.
3- The ECRB muscle is important in dorsal approach to the radius: the Thompson dorsal approach to the proximal radius may be used for exposure of the posterior aspect of the radial shaft.
The incision is made in between the two muscles of the ECRB and the extensor digitorum.
4- In tennis elbow surgery, excessive release of the tendon (ECRB) and the lateral side of the elbow can cause elbow instability.
Excessive release of the ECRB tendon (the origin) during tennis elbow surgery can cause injury to the ulnar humeral collateral ligament and elbow instability.
Please note the proximity of the origin of the ECRB tendon to the ulnar humeral collateral ligament, the ligament is close to the tendon and can be injured due to excessive release.
5- Tendon transfer in high radial nerve palsy: the injury to the radial nerve results in wrist drop due to paralysis of the wrist extensors.
The pronator teres transfer to the ECRB is a very popular tendon transfer in high radial nerve palsy, used to restore wrist extension.

ABSTRACT
Radial nerve palsy is a debilitating nerve injury that results in lost of wrist and finger extension, which classically presents as wrist drop. The two reconstructive options for managing this injury are tendon transfers and nerve transfers, each with their advantages and disadvantages. Nerve transfers are able to provide independent finger extension, however there is an associated prolonged recovery period in comparison to tendon transfers for radial nerve palsy. Electing the appropriate surgical management depends on the patient’s demands and needs. Nerve transfers for radial nerve palsy includes two transfers: (1) FCR to PIN and (2) FDS to ECRB. The tendon transfer for wrist extension can be elected for an early outcome and includes the transfer of the pronator teres to ECRB tendon. In this case, the patient presented three months following a severe MVC and suffered a radial nerve transection associated with a humeral facture. Due to the patient’s needs, the median to radial nerve transfers were elected with the pronator teres to ECRB tendon transfer. To restore radial nerve sensation, an end-to-side nerve transfer was additionally performed and included the radial sensory nerve end-to-side into the sensory component of the median nerve.
