This topic is, sooner or later, it becomes an interesting and in some ways even more important for the players in airsoft, paintball, hardbol and more. But do not forget that the ability to correctly and clearly and silently communicate with gestures can be very helpful and far from the game conditions and situations. So, I suggest to learn the basic gestural commands and their values."Attention" - Putting up his hand, fingers, palms together
Team for all - Circular movement of the forearm over his head, fingers palms together
Total collection - Vertical movement Read more [...]
Disarticulation forearm produced instead of amputation shoulder, often in military field. Prosthetics rotation axis artificial elbow joint is located below the axis of rotation to the opposite side. The operation usually produces a circular manner.
Lower joint space by 1/6 of the circle elbow circular slit cut through the skin with subcutaneous fat and superficial fascia. The projection of the joint space on the front surface of the joint is given by the broken line A. The horizontal part corresponds to the gap of the radial head, and angled-slit on the coronoid process. The top point of the Read more [...]
When not close examination fails to detect damage to the nerves, tendons, dislocation of the radial head and the head of the ulna fracture Montedzhi and Galeazzi. Erroneous multiple attempts at conservative reposition the interposition of soft tissues. Fractures that can not be an attempt to reposition the case of double or have a tendency to secondary displacement in the cast are subject to surgery. Inattention to patient complaints to compression of a plaster cast, movement disorder and the sensitivity of fingers, edema, cyanosis or pallor brush threatening pressure sores (see) or the development Read more [...]

Injuries to the forearm the athletes are most often represented fractures, acute injuries of muscles and tendons, as well as injuries. Acute injuries are the most common and account for about 58%, chronic traumatic diseases - about 42% (which is often chronic mioentezity, ie diseases of the muscles and tendons). The specifics of injuries and diseases of the forearm shows Table. 5. Table 5: The nature of injuries and diseases No. of Acute injuries:

Rupture of the distal biceps tendon seen in gymnasts with great sports experience and coaches. Tendon comes off in his attachment to the tuberosity radiation bone at a sharp blow to the front of the forearm.
Symptoms. At the time of rupture patient notes a sharp pain and a characteristic crack, there is a weakness in the hand, swelling of the anterior surface of the elbow joint, and later extensive haemorrhage. During inspection and palpation determined retraction in the region of the distal biceps tendon, muscle is slightly shifted upwards. Although the range of motion of the elbow is almost Read more [...]
Fractures diaphysis both bones of the forearm result from direct trauma or a fall on the outstretched hand. Both bones are broken at the same level.
Symptoms. In the fracture strain due to bending is determined by the longitudinal axis of the forearm. In the place of the fracture is swelling, observed abnormal mobility and bone fragments bone crunch.
Fractures of the forearm without bias harder to recognize. At the site of the fracture is usually a swelling. Marked pain on palpation. Radiographs clarify the diagnosis.
Fig. 11. Comminuted fracture diaphysis of the radius (the state after Read more [...]
Improper transport immobilization of forearm fractures in the upper and middle thirds of the elbow without the seizure may cause the displacement of bone fragments, soft tissue trauma and neurovascular bundle. Insufficiently attentive examination of the function of fingers and sensitivity of such fractures may be the cause of delayed diagnosis of nerve damage.
Removal of the cast until the bone fusion - Rough bug, leading to nonunion fractures, education deformation (bending), pain, formation of false joints, which eliminates the possibility of sports and can cause permanent disability.
Lack of Read more [...]
In the practice of sports traumatology most common rear dislocations of the forearm (Up to 90% of all elbow dislocations) arising at the time of the fall on a straightened arm at the elbow.
Symptoms. The elbow distorted with swelling and bleeding. Forearm is in the extension of a fixed part (120-140 °) and slightly pronated. Movement impossible. Leverage seems elongated and forearm - Shortened. The tip of the olecranon is 2-3 cm above the condyles of the shoulder. Defined symptom springy resistance. The first step is to conduct X-ray examination and immediately send the patient to a specialized Read more [...]
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 [...]
Fractures of the radius in a typical place (Fig. 17) up to 70% of forearm fractures and 10% of all fractures in general. They are metaepifizarnym fractures and often combined with simultaneous fracture of styloid process of the ulna. Fractures occur from a fall on the outstretched arm forward or hit the palm. The most common extensor fracture Number of forest, less flexion fracture Smith. The latter occurs when falling on the dorsum of the hand or on impact. Possible fractures without displacement (crack, impacted fracture) and offset. Fracture plane passes by 1-2 cm proximal to the lower Read more [...]
Fractures of the head and neck radiation bones are more common in the fall on an outstretched hand. At the same time, simultaneous elevation of cartilage damage capitate humerus. Distinguish between cracks and fractures of the head without bias, marginal fractures with displacement, trimmed fracture head (Fig. 9). Isolated fractures usually occur in children 8 - 12 years, breaking a head found in them is extremely rare.
The diagnosis is based on the presence of swelling and tenderness in the head radius, limitation of active and passive movements (often with delicate notes bone crunching). Read more [...]
Fracture diaphysis of the radius with dislocation of the head ulnar bone (fracture Galeazzi) often occurs as a result of indirect trauma, accompanied by rupture of the ligaments in the lower radioulnar articulation and often fractured ulnar styloid ulna. In addition to the symptoms characteristic of a fracture of the radius, there is swelling and pain in the head ulna. The distal end of the latter is shifted to the back or side of the palm, easy to reduce a pressure-sensitive, but once again pops up.
Reduction - as in fractures of both bones of the forearm. Cast latching and radial-ulnar carpal Read more [...]
Elbow injuries are accompanied by bleeding into the surrounding soft tissue, mucous bag, as well as in the joint cavity. Often there is the ulnar nerve injury, which is accompanied by sharp pains radiating to the IV and V fingers. Sometimes bruised elbow synovitis complicated, chronic traumatic bursitis, ulnar neuritis, myositis ossificans, limiting movement in the joint.
Sprains of the elbow occur when its excessive extension (while playing tennis, the exercises performed with weights, etc.), followed by a break capsule hemarthrosis. Treatment for bruises and sprains: immobilization with a Read more [...]
Closed injuries of soft tissues of the forearm (mostly injuries) are recognized and treated by the general rules (see Injury). Nerve damage - see above.
Soft tissue injuries forearm are of great importance if the wound penetrates the aponeurosis. In the small cross section of the forearm is placed a large number of various anatomical structures that lie in close proximity, especially in the distal third of the forearm. Therefore injured P., especially firearms, many more than any other segment of the injured upper limb lead to serious violations of functions, mainly due to the development of Read more [...]
