Radial Capital: What is it? Anatomy, Function and Fractures of A.Griguolo

Generality The radial capital is the characteristic enlarged area that constitutes the proximal end of the radium. Completely smooth due to the presence of a layer of articular cartilage, the radial capital is the portion of the radio delegated to interact with the humerus, to form the articulation of the elbow, and with the proximal end of the ulna, by gender the proximal radio-ulnar joint

Brachial

The brachialis muscle is placed deeper than the brachial biceps. It originates from the distal half of the anterior aspect of the humerus (below the deltoid insertion) and from the intermuscular septa. It ends on the ulnar tuberosity and on the joint capsule. In contrast to the biceps brachialis muscle it is a monoarticular muscle which, with its action, flexes the forearm

Hamstring

The biceps femoris muscle occupies the posterior and lateral region of the thigh and is composed of two heads, one long and one short. The long head originates from the upper part of the ischial tuberosity with a common head to the semitendinosus muscle. The short head originates from the middle third of the lateral lip of the femur line and from the lateral intermuscular septum

Brachioradials

The brachioradialis muscle is a superficial muscle that occupies the lateral region of the forearm and is clearly visible in normal-weight people. It originates on the lateral supracondylar ridge of the humerus (under the groove of the radial nerve) and on the lateral intermuscular septum. It fits into the radial face of the radium styloid process

coracobrachialis

The coraco-brachialis muscle originates, as the name suggests, from the apex of the coracoid process of the scapula, an origin that it shares with the short head of the biceps muscle. It is inserted on the middle third of the anteromedial face of the humerus. It is found medially and deeply at the short head of the triceps

Short extender of the thumb

The extensor short muscle of the thumb is a deep muscle of the posterior region of the forearm. Located in a medial position with respect to the long abductor muscle of the thumb, it originates from the ulna, the interosseous membrane and the dorsal face of the radium. With his insertion tendon he crosses the 1st dorsal carpal ligament duct and inserts himself into the dorsal base of the proximal phalanx (1a) of the thumb

Body organization

Anatomical axes: they can be compared to skewers that cross the body. These imaginary lines are used to trace the axis on which the rotational movements take place. A bit like what happens to the hinges of a door. The door moves in a plane around an axis. The plane (the door) is determined by the orientation of the pin in the hinge (axis)

Deltoid

The deltoid muscle externally covers the lateral part of the shoulder joint. It is composed of three parts: a clavicular part, an acromial part and a spinal part. The clavicular (anterior) part originates from the lateral third of the anterior margin of the clavicle; the acromial (medial) originates from the apex and from the lateral margin of the acromion; the spinal one (posterior) originates from the lower lip of the spine of the scapula All three parts are inserted at the deltoid tuberosity of the humerus The deltoid muscle is the most powerful abductor of the humerus up to 90 °, especially

Extender just for the little finger

The extensor muscle of the little finger is a superficial muscle of the posterior region of the forearm, placed medially in relation to the common extensor muscle of the fingers. It originates along with this muscle from the posterior aspect of the humeral epicondyle and from the antibrachial fascia

Common finger extender

The common extensor muscle of the fingers is located in the posterolateral part of the forearm. It is a superficial muscle that originates from the posterior aspect of the lateral epicondyle of the humerus, from the lateral collateral ligament, from the annular radial ligament and from the antibrachial fascia

Lower posterior tooth

The posterior inferior dentate muscle originates from the posterior leaflet of the lumbodorsal fascia (at the level of the spinous processes of T11-T12 and L1-L3). It is placed deeper than the large dorsal muscle, it covers the iliocostal, the very long of the back, the ribs and the intercostal muscles
