Fractures of the forearm

Fractures of the forearm divided into the following three groups. 1. Intra-articular fractures of the elbow: a) fracture of the olecranon, and b) fractures of the head and neck of the beam, c) fractures and detachments of the coronoid process ulnar bone. 2. Diaphyseal forearm fractures: a) fractures of both bones of the forearm, and b) an isolated fracture of the shaft of the ulna without dislocation and dislocation of the radial head, and c) an isolated fracture diaphysis of the radius without dislocation and dislocation of the head ulnar bone. 3. Fractures of the lower end of the radius: Read more [...]

Isolated fracture of the ulna with dislocation of the radial head forearm

Isolated fracture of the ulna with dislocation of the radial head (fracture Montedzhi) may be flexor and extensor (Fig. 16). When flexion occurs posteriorly dislocated head beam, and fragments of the ulna form a corner, open front. When the extensor - dislocated head, accompanied by rupture of the annular ligament, going forward and outward. The ulna is broken in the upper third, the angle formed between the fragments, open posteriorly. May damage the radial nerve head is moved. The most common extensor fracture. Dominates the direct mechanism of injury. Recognition is based on the clinical Read more [...]

Congenital forearm

Congenital dislocation of the radial head, usually unilateral, is very common. Observed in the absence of bone changes, in combination with a congenital defect and shortening of the radius. Main dysfunction - the inability to supination. Over time, there is laxity in the joint. When the diagnosis of X-ray examination is essential. Radiographs (Figure 6) ulna shortened and lengthened over radiation, acts posterior to the joint space and lifts the conical skin fold. Head beam convex like mushroom caps. Capitate elevation area atrophied, and coronoid process of the ulna, on the contrary, developed Read more [...]

Connection of forearm

Head of radius and radial notch of the ulna form articulatio radioulnaris proximalis, which is described with the first segment, because it is included in its composition, and functionally integrated with a second similar joint, located at the distal end of the forearm. Distal radioulnar joint (Articulatio radioulnaris distalis) formed joint head circumference of the ulna and radial notch. Cylindrical shape of the joint, the movements are possible only on the vertical axis (Fig. 127). Of the ulnar notch radiation bone to the styloid process of the ulna moves fibrous cartilage triangular shape, Read more [...]

Ulna

Ulna (Ulna) is a long tube of irregular shape (Fig. 89), located on the medial side of the forearm. It distinguish upper and lower epiphyses and body. The upper (proximal) end is more massive than the lower (distal), and the device it is more complicated. Ginglymoid notch (incisura trochlearis) repeats the shape of the block bounded by the humerus and the front of the coronoid process (processus coronoideus), rear - elbow (olecranon). On the side in a shallow cut ginglymoid radial notch (incisura radialis) - place of articulation with the radial head. Front and below the coronoid process Read more [...]

The site also has a large section devoted to video on survival survivalist-known professionals around the world.

The main theme of the site, "Survival in the wild nature" - is to be ready to be in the wild, and the ability to survive in extreme conditions.

The Survival in the wild nature - how correctly to behave, it having appeared in an emergency situation. Ability to find a way out from any situation: to kindle a fire, to put traps, to prepare food, to arrange dwelling and a lodging for the night; to learn to knit knots, to clear water, to be guided by districts, correctly to choose equipment, a knife.
