Large medical dictionary

The girdle of the upper limb includes paired clavicles and shoulder blades. The clavicle is movably connected with the sternum at its medial end, and with the scapula at its lateral end; The scapula is not connected to the bones of the body, but is located among the muscles. Thanks to these features, a high degree of mobility of the scapula is created, which is reflected in the freedom of movement of the upper limb. Due to the lateral angle of the scapula, the upper limb is moved further from the midline of the body to the periphery. The scapula, being in the muscles, weakens shocks and tremors during labor processes. Thus, the scapula and clavicle connect the bones of the trunk and the free part of the upper limb.

Collarbone

The collarbone (clavicula) is a paired tubular S-shaped bone that contours under the skin (Fig. 86). It contains the sternal end (extremitas sternalis) with an articular platform. It is more massive than the opposite, acromial end (extremitas acromialis).

86. Right collarbone.
1 - extremitas acromialis; 2 - extremitas sternalis; 3 - tuberculum conoideum.

The upper surface of the clavicle is smooth, and on the lower surface in the area of the acromial end there is a cone-shaped tubercle (tuberculum conoideum).

Ossification. The clavicle is classified as a primary bone by its type of ossification. The center of ossification of the clavicle appears in the connective tissue base of its middle part at the 6-7th week of intrauterine development. At the sternal end, the ossification nucleus appears at the 12-16th year of life and fuses with the body by 20-25 years.

Spatula

The scapula (scapula) is a paired, flat, thin, triangular-shaped bone, with its lower angle facing down (Fig. 87). There are medial, lateral and upper edges (margines medialis, lateralis et superior) and three angles: lower (angulus inferior) - located at the junction of the lateral and medial edges of the scapula, upper (angulus superior) - at the connection of the medial and upper edges, lateral ( angulus lateralis), at the connection of the upper and lateral edges. The most complex structure is the lateral angle of the scapula, on which there is a grooved glenoid cavity (cavitas glenoidalis), which participates in the formation of the shoulder joint, and the coracoid process (processus coracoideus). This process is located medial and superior to the glenoid cavity and its apex is directed forward. Above and below the cavity, the supraglenoid and subarticular tuberosities are visible. The posterior surface of the scapula is divided by a spine (spina scapulae), which reaches the lateral angle and hangs over it (acromion). Above the spine, a supraspinous fossa (fossa supraspinata) is formed, below - an infraspinatus fossa (fossa infraspinata) larger than the previous one. The entire costal (anterior) surface of the scapula forms the subscapular fossa (fossa subscapularis). In older people, resorption of the compact substance of the scapula occurs and sometimes holes appear in the supraspinatus and infraspinatus fossae.

87. Right shoulder blade (rear view) (according to R. D. Sinelnikov).

1 - angulus superior;
2 - angulus lateralis: 3 - angulus inferior;
4 - spina scapulae;
5 - processus coracoideus;
6 - acromion;
7 - cavitas glenoidalis;
8 - fossa infraspinata;
9 - margo lateralis;
10 - margo medialis;
11 - fossa supraspinata.

Ossification. Ossification of the scapula begins from the 2nd - 3rd months of intrauterine development in the form of a calcification core in a triangular cartilaginous plate; a separate ossification nucleus appears in the coracoid process in the first year of life and fuses with the scapula by 16-17 years of age. Ossification of the remaining cartilaginous parts of the scapula ends at 18-25 years.

Bones of the upper limb girdle - scapula, clavicle.

The collarbone, clavicula, is a small S-shaped bone. It has a body, corpus claviculae, and two ends: the sternal, facing the manubrium of the sternum, and the acromial, connecting to the acromion. The sternal end and the adjacent portion of the body of the clavicle are curved with a convexity forward, and the rest of the clavicle is curved with a convexity backward.

The middle section of the clavicle, located between its ends, is somewhat compressed from top to bottom. On its lower surface there is a relatively large nutritious opening, foramen nutricium. At the sternal end there is a depression of the costoclavicular ligament, impressio lig. costoclavicularis, and at the humeral end there is a cone-shaped tubercle, tuberculum conoideum, and a trapezoidal line, linea trapezoidea (places of attachment of the conical and trapezoidal parts of the coracoclavicular ligament, lig. coracoclaviculare). On the lower surface of the clavicle, closer to the acromial end, lies the groove of the subclavian muscle, sulcus m. subclavia. The upper surface of the clavicle is smooth. The sternal end, extremitas sternalis, is thickened and carries on its inner surface the sternal articular surface, fades articularis sternalis - the place of articulation with the clavicular notch on the manubrium of the sternum. The acromial end, extremitas acromialis, is wider than the sternal end, but somewhat thinner. On its outer lower part there is the acromial articular surface, facies articularis acromialis, which articulates with the acromion of the scapula.

How to determine whether the collarbone is on the right or left side

The sternal end of the clavicle is rounded, the acromial end is flattened

The upper surface of the clavicle is smooth, the lower surface is rough

The medial bend of the clavicle is directed anteriorly, the lateral – posteriorly

The scapula, scapula, is a flat triangular bone adjacent to the posterior surface of the chest in the space from the II to VII ribs. According to the shape of the bone, three edges are distinguished in it: the medial one, facing the spine, margo medialis, the lateral one, margo lateralis, and the upper one, margo superior, on which the notch of the scapula is located, incisura scapulae. The listed edges converge with each other at three angles, of which one is directed downward (lower angle, angulus inferior), and the other two (upper, angulus superior, and lateral, angulus lateralis) are located at the ends of the upper edge of the scapula.

The lateral angle is significantly thickened and equipped with a slightly deepened, laterally facing glenoid cavity, cavitas glenoidalis. The edge of the glenoid cavity is separated from the rest of the scapula by an interception, or neck, collum scapulae. Above the upper edge of the cavity is a tubercle, tuberculum supraglenoidale, the site of attachment of the tendon of the long head of the biceps muscle. At the lower edge of the glenoid cavity there is a similar tubercle, tuberculum infraglenoidale, from which the long head of the triceps brachii muscle originates. The coracoid process, processus coracoideus, extends from the upper edge of the scapula near the glenoid cavity.

The anterior surface of the scapula, facing the ribs, facies costalis, is a flat depression called the subscapular fossa, fossa subscapularis, where the so-called subscapularis is attached. On the posterior surface of the scapula, facies dorsalis, there passes the spine of the scapula, spina scapulae, which divides the entire posterior surface into two unequal fossa sizes: the supraspinous, fossa supraspinata, and the infraspinatus, fossa infraspinata. The spina scapulae, continuing to the lateral side, ends in the acromion, acromion, hanging behind and above the cavitas glenoidalis. It contains an articular surface for articulation with the clavicle - facies articularis acromii.

The skeleton of the free upper limb (skeleton membri superioris liberi) of a person is formed, in accordance with the general diagram of the vertebrate skeleton, into three sections - the shoulder, forearm and hand.

Shoulder (brachium)

The human shoulder is formed by a single humerus (humerus), the structure of which consists of a body and two ends.

The body of the humerus (corpus humeri) in its upper part has a cylindrical shape, but below it becomes triangular; accordingly, three surfaces are distinguished here - the posterior (facies posterior), the lateral anterior (facies anterior lateralis) and the medial anterior (facies anterior medialis); These surfaces are separated by edges - medial (margo medialis), anterior (margo anterior) and lateral (margo lateralis). The lateral anterior surface bears the deltoid tuberosity (tuberositas deltoidea) for the attachment of the deltoid muscle; and the posterior surface is the groove of the radial nerve (sulcus nervi radialis).

The upper end of the humerus is expanded and forms the head of the humerus (caput humeri), separated from the body by the surgical neck (collum chirurgicum). Along the edge of the head there is a groove - the anatomical neck (collum anatomicum), and between it and the surgical neck there are two tubercles: the large tubercle (tuberculum majus) is located laterally, and in front of it is the small tubercle (tuberculum minus). From each of these tubercles two ridges extend downward - respectively, the crest of the greater tubercle (crista tuberculi majoris) and the crest of the lesser tubercle (crista tuberculi minoris); the space between them is called the intertubercular groove (sulcus intertubercularis).

The lower end of the bone is also expanded - here is the condyle of the humerus (condylus humeri), the medial part of which is called the block of the humerus (trochlea humeri) and is intended for articulation with the ulna, and the lateral part is the head of the condyle of the humerus (capitulum humeri), to which the radius is attached. Above the block of the humerus on the front side is the coronoid fossa (fossa coronoidea), which includes the coronoid process of the ulna, and on the back side there is the olecranon fossa (fossa olecrani) for, respectively, the olecranon process of the ulna. Above the head of the condyle on the anterior side lies the radial fossa (fossa radialis). Further, above the condyle of the humerus there are two epicondyles - called onymedial (epicondylus medialis) and lateral (epicondylus lateralis); even higher, these epicondyles pass into the corresponding supracondylar ridges - lateral (crista supracondylaris lateralis) and medial (crista supracondylaris medialis).

Forearm (antebrachium)

The human forearm is formed, as it should be, by two bones - the radius and the ulna, their ends touching and separated in the middle by the interosseous space of the forearm. Each bone, like the humerus, consists of a body and two ends, upper and lower.

Radius (radius)

The radius is located laterally. Its body is triangular and formed by three surfaces - anterior (facies anterior), posterior (facies posterior) and lateral (facies lateralis); as well as three edges - anterior (margo anterior), posterior (margo posterior) and interosseous (margo interosseus); the anteromedial side bears the tuberosity of the radius (tuberositas radii) for the attachment of the biceps brachii muscle.

The proximal end of the radius is called the head of the radius (caput radii); it is separated from the body by the neck of the radius (collum radii); The head bears a flat depression - the articular fossa (fossa articularis), into which the head of the condyle of the humerus enters, and around the head there is an articular circle (circumferentia articularis) for articulation with the ulna.

The distal end of the radius bears the carpal articular surface (facies articularis carpea) for articulation with the bones of the wrist, as well as on the lateral side the ulnar notch (incisura ulnaris) for connection with the head of the ulna, and on the medial side - the styloid process (processus styloideus).

Ulna (ulna)

The ulna lies medially; its body is also triangular and is formed by three surfaces - anterior (facies anterior), posterior (facies posterior) and medial (facies medialis); and three edges - anterior (margo anterior), posterior (margo posterior) and interosseous (margo interosseus).

The proximal end of the bone articulates with the block of the humerus in the region of the trochlear notch (incisura trochlearis), which has two processes - the anterior coronoid (processus coronoideus) and the posterior ulnar (olecranon). The coronoid process, in turn, has a radial notch (incisura radialis), which articulates with the articular circumference of the radius, and passes downwards into the tuberosity of the ulna (tuberositas ulnae).

As for the distal end, it ends with the head of the ulna (caput ulnae), which has an articular circle (circumferentia articularis) for connection with the radius, and on the medial side, like the radius, the styloid process (processus styloideus).

Brush (manus)

The human hand, according to the general diagram of the vertebrate skeleton, is divided into the wrist, metacarpus and phalanges of the fingers.

Wrist (carpus)

The wrist is formed by two rows of small spongy bones:

the proximal row includes the scaphoid bone (os scaphoideum), as well as the lunate (os lunatum), triquetrum (ostriquetrum) and pisiform bones (os pisimorme)

to the distal – polygonal or bone - trapezium (os trapezium), trapezoid os trapezoideum), capitate oscapitatum) and hook-shaped (os hamatum)

Pastern (metacarpus)

The metacarpus is formed by five short tubular metacarpal bones (ossa metacarpalia), forming the palm and each consisting of a body (corpus), base (basis) and head (caput).

Phalanges of the fingers (phalanges digitorum)

The phalanges of the fingers are short tubular bones; each finger, except the thumb, has 3 phalanges - proximal (phalanx proximalis), middle (phalanx media) and distal (plananx distalis); in the thumb there are only proximal and distal phalanges. In each phalanx, the base of the phalanx (basis phalangis), the body of the phalanx (corpus phalangis) and the head of the phalanx (caput phalangis) are distinguished. The ends of the distal phalanges are flattened and form each tuberosity of the distal phalanx (tuberositas phalangis distalis).
