Dislocation of the forearm
Dislocation of the forearm at the elbow there. It is common, but somewhat less than a dislocated shoulder. Dislocation of the forearm is:
Elbow joint articular surface of the form of three bones: the humerus, ulna and radius. Joint capsule is thin, but with the sides of the joint reinforce two strong ligaments. Chance of a dislocation of both bones of the forearm (ulna and radius) and one of them.
Posterior dislocation of the forearm occurs more frequently. It occurs in the fall on the outstretched straighten arm at the elbow. The lower part of the humerus breaks the capsule of the joint and move forward. Sometimes this is accompanied by dislocation of the humeral epicondyle separation in adolescents or condyle fracture of the shoulder in adults. The patient complains of pain in the elbow joint and keeps the victim in the arm flexion. The form of the elbow joint changes. Movement of the elbow sharply limited and painful. Clarify the diagnosis with X-rays, without the fractures in the elbow joint.
Treatment of posterior dislocation of the forearm. Anesthesia is performed with local anesthetic solutions. Sometimes the reduction is carried out under joint anesthesia. Assistant surgeon with the help of special techniques (flexion or hyperextension) reduce a joint. Then, a radiological control correct reduction and plaster cast is applied for two weeks. Immediately recommended physiotherapy available in the joints of the hand. After removing the plaster is assigned physiotherapy and physiotherapy for the development of the elbow.
Anterior dislocation of the forearm is rare. It occurs when the direct impact in the area of the elbow when the arm is bent at the elbow. Often at the same time there is a fracture of the olecranon humerus. The patient complains of pain in the elbow joint. The hand is straightened at the elbow position. Bending is impossible and sharply painful. Clarify the diagnosis with X-rays. Treatment consists in the reduction of the joint under local anesthesia or general anesthesia.
Occasionally the outer arm dislocated. Typically, these dislocations are not complete. There is a subluxation of the joint by direct force action directed from within outwards in the frontal plane. The patient complains of pain in the joint. Movement in the joint is limited. The shape of the joint changed. The axis of the joint is displaced outwards. Be sure to X-rays are carried out to refine the diagnosis and exclusion of fractures. Treatment. Local anesthesia or general anesthesia. Forearm reduce a. The cast is applied for up to 3 weeks.
Dislocation of the forearm inwards occurs when a direct hit from the side, directed medially in the frontal plane. The axis of the joint with displaced medially. Treatment is similar to other dislocations of forearm. In children, there are dislocations of the ulnar head and radial bones. They reduce a local anesthesia, followed by a plaster splint for 3 weeks.
There are not very often. The higher number of cases of children radial head subluxation. It is found only in children younger than 4 years. The mechanism of injury – stretching the hand of the child. The child complains of pain in his hand. Elbow flexion is absent, the handle hanging down along the trunk. When probing the pain occurs in the elbow and wrist in the affected arm. X-rays do not always, as they provide little information. When the diagnosis guided by the clinical picture.
Treatment. Usually a dislocation can straighten quickly and relatively painlessly, so the pain often does not hold, since it may become more trauma for the child than the actual reduction. Then hand it is recommended to hang a scarf for a week, sometimes it becomes necessary to impose a plaster splint. We recommend therapeutic exercise and physical therapy.
