The brachioradialis muscle is a versatile motor muscle and is used for different transfers in tetraplegic patients. In IC 1 it is used to restore wrist extension, while in IC 2–8 it is used to restore finger extension (m.extensor digitorum communis) and finger (m.flexor digitorum profundus) or thumb flexion (m.flexor pollicis longus).

The anterior interosseous nerve is a branch of the median nerve, with a large sensory branch to the wrist bones, which arises just below the elbow. It passes distally, anteriorly along the interosseous membrane and innervates flexor pollicis longus, flexor digitorum profundus to index and middle finger as well as pronator quadratus, and supplies sensory feedback from the wrist bones, i.e. the ...
The wrist may be immobilized in order to prevent further use and inflammation. When surgery is needed, the flexor retinaculum is either completely severed or lengthened. [5] Surgery to divide the flexor retinaculum is the most common procedure. [citation needed] The scar tissue will eventually fill the gap left by surgery. The intent is that ...
These three muscles act as flexors at the elbow joint. [5] The extensor carpi radialis brevis and longus are both weak flexors at the elbow joint. Brevis moves the arm from ulnar abduction to its mid-position and flexes dorsally. Longus is a weak pronator in the flexed arm and a supinator in the outstretched arm.
In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder, thus decreasing the angle between the upper arm and the forearm.
The brachioradialis, flexor of the elbow, is unusual in that it is located in the posterior compartment, but it is actually a muscle of flexor / anterior compartment of the forearm. The anconeus, assisting in extension of the elbow joint, is by some considered part of the posterior compartment of the arm.
The radial nerve innervates the finger extensors and the thumb abductor; that is, the muscles that extend at the wrist and metacarpophalangeal joints (knuckles) and abduct and extend the thumb. The median nerve innervates the flexors of the wrist and digits, the abductors and opponens of the thumb, the first and second lumbricals. The ulnar ...
Any fracture in the elbow region or upper arm may lead to Volkmann's ischemic contracture, but it is especially associated with supracondylar fracture of the humerus. It is also caused by fractures of the forearm bones if they cause bleeding from the major blood vessels of the forearm. [citation needed]
