A marked reduction of activity in extensor carpi radialis brevis
(44%) and biceps brachii (23%) was observed while the patient performed a gripping task with the scapula position actively corrected, compared to no correction.
Lateral epicondylitis, or "tennis elbow," refers to chronic micro-tearing of the extensor carpi radialis brevis
and/or extensor digitorum communis.
The WDFHO enables persons with tetraplegic SCI to attain a functional tenodesis grasp that creates enough passive tension in the paralyzed thumb and finger flexor muscles (such as flexor pollicis longus, flexor digitorum superficialis, and flexor digitorum profundus) with active wrist extension by contraction of the innervated extensor carpi radialis brevis
(ECRB) and extensor carpi radialis longus (ECRL).
It bifurcates at the level of the elbow joint into the superficial nerve, which courses dorsally under the extensor carpi radialis brevis
, and the PIN, which dives under the superficial head of the supinator muscle and continues along with the posterior interosseous artery to supply all of deeper lying extensor muscles.
This is due to the relative preservation of the extensor carpi radialis longus (ECRL) along with a non-functional extensor carpi ulnaris (ECU) that is dynamically not balancing the action of the functioning ECRL and extensor carpi radialis brevis
a) Transfer of pronator teres (PT) to extensor carpi radialis brevis
(ECRB) for wrist extension,
This anomalous muscle has been described as a flexor carpi radialis brevis
By contrast, the 38th edition of Gray's (1995) consists of 2092 pages and on page 845 the muscle is now called extensor carpi radialis brevis
(ECRB); this formidable book weighs 8 3/4 pounds
The Nirschl repair involves freeing tendinosis tissue from the extensor carpi radialis brevis
muscle through a 1.
Close attention was paid to two specific muscles, the extensor carpi radialis brevis
(ECRB) and the extensor digitorium communis (EDC), which are located beside each other in the forearm and originate from the bony prominence on the outside of the elbow.
Because the ulnar shaft fracture was proximal, the incision was carried further proximally in a lateral approach to the radiocapitellar joint, between the extensor carpi radialis longus and extensor carpi radialis brevis
and the radial collateral ligament.
