With hands outstretched and palms beside the body , can be noticed that hands and forearms are not touching the body. The existence of an angle of 5-15 degrees is normal and allows the movement of the forearms. After injuries o, this angle can be increased and forearms are too far from the body, or may decrease, resulting a deformation.
The posterior dislocation happens when the person falls with the arm extended and is more common than the anterior one and studies have shown that is more frequent in men . The anterior elbow dislocation may be caused by a force, by a strong blow.
Before the diagnose and the treatment it is very important to know exactly what caused the elbow dislocation, what movements the patient is able to perform and what movements is not able to, from where the pain comes from. Also a radiography is compulsory in order to see the exact situation of the patient.
Besides elbow dislocation, may also be the case of vascular injury, then an arteriography is indicated. The reduction is not recommended at the place of the accident. But after the results of the tests is ready the reduction has to be done quickly in order to avoid complications. Prior to this operation the patient needs analgesics.
The treatment for posterior elbow dislocation is different from anterior elbow dislocation. The reduction for anterior elbow dislocation is done with traction on the wrist and pressing the forearm backward. In case of posterior elbow reduction the doctor may choose two possible ways. The first method is with a 90 degrees angle flexion and applying downward pressure on the forearm simultaneous with pressure on the hymerus. The second method implies the humerus to rest on the table and the forearm to hang on a perpendicular position. A little weight is applied on the wrist and after some minutes the reduction is over. There may appear complications like : ulnar nerve injury, brachial artery injury, and myositis ossificans.
