The Radial Forearm Flap Anatomic considerations. Preoperative Assessment. The skin of the volar forearm provides relatively thin and reliable coverage for a wide variety of defects. Because the radial aspect of the arm is hair bearing, the amount and quality of the hair is a consideration in using this flap for resurfacing.

- Madelung deformity is an epiphyseal growth plate disturbance characterised by dorsal and radial bowing of the radius with resultant cosmetic effects and decreased grip strength.It can be bilateral in 50-66% of patients.he deformity is characterised by: 1  dorsal and radial bowing of the radius. 2  exaggerated palmar (up to 35°) and ulnar tilt (up to 60°) of the radiocarpal articulation 3. 3  failure of ossification of the ulnar side of the distal radial epiphysis.

Palmar Radial Extrinsic Wrist Ligament - long radiolunate ligament : - parallel to radioscaphocapitate ligament, runs from the palmar rim of the distal part of the radius to the radial margin of palmar horn of lunate; - radiolunate ligament (RLL): this goes on to pass from lunate to triquetrum as lunotriquetral ligament; Discussion: - short radiolunate ligament: - arises from palmar fibers of TFCC, originates from palmar margin of distal part of radius and inserts into proximal part of palmar surface of lunate;

Pronator Teres: Functional Anatomy Guide Notably, it also plays a minor role in elbow flexion. It is part of the superficial anterior compartment of the forearm. The pronator teres, which has a humeral head and an ulnar head, is found lateral to the palmaris longus and medial to the flexor carpi radialis.

Brachioradialis The brachioradialis is a stronger elbow flexor when the forearm is in a midposition between supination and pronation at the radioulnar joint. When pronated, the brachioradialis is more active during elbow flexion since the biceps brachii is in a mechanical disadvantage.

Posterior compartment of the forearm The posterior compartment of the forearm (or extensor compartment) contains 12 muscles which are chiefly responsible for extension of the wrist and digits, and supination of the forearm. It is separated from the anterior compartment by the interosseous membrane between the radius and ulna.he brachioradialis, flexor of the elbow, is unusual in that it is located in the posterior compartment, but it is actually in the anterior compartment of the forearm.

Anatomy Anatomy. The bones of your forearm are the radius and the ulna. If you hold your arms at your side with your palms facing up, the ulna is the bone closest to your body and the radius is closest to your thumb. The ulna is larger at the elbow — it forms the point of your elbow — and the radius is larger at the wrist. The primary motion of the forearm is rotation: the ability to turn our palms up or down. The ulna stays still while the radius rotates around it.

Ulnar artery Wrist. At the wrist the ulnar artery is covered by the integument and the volar carpal ligament, and lies upon the Flexor retinaculum of the hand. On its medial side is the pisiform bone, and, somewhat behind the artery, the ulnar nerve. Peculiarities

UV becomes more positive in pronation. 3  Negative ulnar variance UV decreases in supination.

Radial nerve Muscles of the posterior forearm. All the labelled muscles (that is, all the visible muscles except the ones on the dorsal hand and one at top left) are innervated by the radial nerve, and represent all muscles innervated by the radial nerve except for the supinator.ith the lateral and medial heads of the triceps innervated, the radial nerve emerges from the radial groove on the lateral aspect of the humerus. At this point, it pierces the lateral intermuscular septum and enters the anterior compartment of the arm.

Colles' fracture See also: Distal radius fracture. A Colles' fracture, is a fracture of the distal radius in the forearm with dorsal (posterior) and radial displacement of the wrist and hand.

Wrist Anatomy The radial collateral ligament (RCL) is on the thumb side of the wrist. It starts on the outer edge of the radius on a small bump called the radial styloid. It connects to the side of the scaphoid, the carpal bone below the thumb. The RCL prevents the wrist from bending too far to the side (away from the thumb).

- The Henry approach is the volar approach to the forearm. The internervous plane is pronator teres (median) and brachioradialis (radial nerve). The arm should be supinated to move the PIN away from the surgical field.

Muscles in the Anterior Compartment of the Forearm Superficial Compartment. The superficial muscles in the anterior compartment are the flexor carpi ulnaris, palmaris longus, flexor carpi radialis and pronator teres. They all originate from a common tendon, which arises from the medial epicondyle of the humerus.

Radial Nerve Course and Muscular Innervation. The radial nerve is the nerve of the posterior arm. This is the case for both the upper arm (three heads of the triceps) as well as the forearm (wrist and finger extensors). The nerve originates from the posterior cord of the brachial plexus (from the ventral rami of C5-T1).

Cardiovascular System of the Arm and Hand The radial artery supplies blood along the lateral side of the forearm and wrist just superficial to the radius bone. As the radial artery passes through the wrist, it approaches the surface of the skin, providing a convenient location for measuring pulse rate.

Pronator teres syndrome In the proximal forearm it gives rise to the anterior interosseous nerve which innervates the flexor of the thumb (FPL), the flexor digitorum profundus of the index finger (FDP IF), and the pronator quadratus, and terminates in a sensory branch to the bones of the wrist, i.e., the carpal tunnel.

Radial nerve It innervates the medial and lateralheads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.he radial nerve originates as a terminal branch of the posterior cord of the brachial plexus. It goes through the arm, first in the posterior compartment of the arm, and later in the anterior compartment of the arm, and continues in the posterior compartment of the forearm.

- The distal radius is part of the radius, one of the two bones in the forearm. The distal radius is the name given to the end of the bone that helps form the wrist joint. The distal radius articulates with three of the eight carpal bones of the wrist. This proximal row of carpal bones includes the scaphoid (navicular), the lunate, and the triquetrum.

3c. The Veins of the Upper Extremity and Thorax The deep veins of the forearm are the venae venæ comitantes of the radial and ulnar veins and constitute respectively the upward continuations of the deep and superficial volar venous; arches they unite in front of the elbow to form the brachial. veinshe Deep Veins of the Upper Extremity. The deep veins follow the course of the arteries, forming their venae venæ. Comitantes they are generally arranged in, pairs and are situated one on either side of the corresponding, artery and connected at intervals by short transverse. branches

- Fractures of the radius or ulna in the forearm are the most common wrist fractures for people of all ages. The radius is the bone on the thumb side of your forearm, and the ulna is the bone of the forearm located on the side of your little finger. Another common traumatic wrist injury is a sprain. With a sprained wrist, the ligaments of the wrist are stretched beyond their normal limits. A ligament is tough, fibrous tissue that connects bones and helps control the motion of a joint.
