Elbow Joint Research Paper
-The positioning of the bones forming the elbow joint produce the hinge synovial joint. This allows the elbow to make extensions and flexion. The extension involves the Triceps brachii and anconeus (the continuation of the tricep brachii). Flexion is involving the; Brachialis, biceps brachii, and brachioradialis.
- The bending of a joint part so that the angle decreases and the two parts come closer together, it called Flexion. The straitening of a joint increasing the two parts to move apart, is called extension. Anything beyond extension is called, Hyperextension which will result in an injury of the elbow to occur. The elbow joint’s function involves the flexing and grabbing of an object, the range movement (ROM) in the elbow …show more content…
This injury occurs when the bones of the forearm (radius and ulna) get dislocated out of place. Where these three bones meet, it becomes dislocated or “out of joint”. Come causes of most elbow dislocations is caused from falls, mainly when the arm is extended completely. If a person is involved in any traumatic incidents, it can result in an dislocation, weather its a car crash or falling while skiing. Some symptoms and signs may include; server pain, swelling, and inability to bend the arm completely, some may experience lose of feeling in their hands or lose a pule. Treatments for the dislocation may include: seeing a doctor so they can can put the elbow back into place, normally medication is given to ease the pain. The doctor will first have to make sure any nerves or arteries were hurt in the incident by checking for pulse, making sure your fingers and wrist move as well as making sure the blood flow is normal. After there will be an X-ray that will be taken, to identify any further breaks in bones, if injury to artery is suspected further tests of an X-ray to your artery may be done. Normally after all of this is done, the injured arm will be placed in a splint to keep the elbow bent and immobilizes the joint till it heals over
