Pronator teres syndrome. Pronator teres syndrome is a compression neuropathy of the median nerve at the elbow. It is rare compared to compression at the wrist (carpal tunnel syndrome) or isolated injury of the anterior interosseous branch of the median nerve (anterior interosseous syndrome).
The Pronator teres test is an indication of the syndrome—the patient reports pain when attempting to pronate the forearm against resistance while extending the elbow simultaneously. The physician may notice an enlarged pronator teres muscle. Tinel's sign the area around the pronator teres heads should be positive. [clarification needed] The ...
The anconeus muscle (or anconaeus / anconæus) is a small muscle on the posterior aspect of the elbow joint. Some consider anconeus to be a continuation of the triceps brachii muscle. [ 1 ][ 2 ][ 3 ] Some sources consider it to be part of the posterior compartment of the arm, [ 4 ] while others consider it part of the posterior compartment of ...
Superficial muscles of the chest and front of the arm. (Lacertus fibrosus visible as white band at lower right.) The bicipital aponeurosis (also known as lacertus fibrosus) is a broad aponeurosis of the biceps brachii, which is located in the cubital fossa of the elbow. It separates superficial from deep structures in much of the fossa.
The pronator teres is a muscle (located mainly in the forearm) that, along with the Pronator quadratus muscle pronator quadratus, serves to pronate the forearm (turning it so that the palm faces posteriorly when from the anatomical position). It has two origins, at the medial humeral supracondylar ridge and the medial side of the coronoid ...
Extensor pollicis longus muscle is labeled in purple. In human anatomy, the extensor pollicis longus muscle (EPL) is a skeletal muscle located dorsally on the forearm. It is much larger than the extensor pollicis brevis, the origin of which it partly covers and acts to stretch the thumb together with this muscle.
Extensor digitorum brevis manus is an extra or accessory muscle on the backside (dorsum) of the hand. It was first described by Albinus in 1758. [1] The muscles lies in the fourth extensor compartment of the wrist, and is relatively rare. [2] It has a prevalence of 4% in the general population according to a meta-analysis. [3]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example). Its symptoms include pain, tingling ...
