The ulna is a bone located in the forearm. The ulna is part of the forearm along with the radius. The distal ulna is part of the bone extremity that is near the wrist. In some cases, the subluxation of the distal ulna can occur. A bone subluxation is basically a partial displacement or dislocation of bones that form a particular joint. A subluxation of the distal ulna involves the wrist and can be simply called as the dislocation of the wrist.
The wrist is formed by the distal ulna and distal radius as well as the carpal bones and bases of the metacarpals. The degree of mobility of the wrist can be determined by health conditions of the distal ulna and other bones that are involved.
Causes
The subluxation of the distal ulna is often caused by an accident in which violent movement of the wrist goes beyond the limit of the joints. Even though subluxations are usually linked with trauma, they can oftentimes occur as a result of a disease that affects the joint and surrounding structures.
Symptoms of subluxation
When subluxation occurs, it can involve the tearing of the ligaments. After the trauma was sustained, the joint will swell and becomes sore, particularly if pressure has been applied.
How subluxation is diagnosed?
When diagnosing a subluxation of the distal ulna, the doctor will perform history taking, physical examination and radiography. Other methods such as CT scan, bone scanning and ultrasonography are also performed in case a diagnosis is difficult to determine.
Treatment
When treating an individual suspected of subluxation of the distal ulna, the basic first aid is to cover the wrist with ice right away to help minimize the swelling, thus reducing the pain. The affected joint must also be immobilized to prevent further injury. While these are essential first aid measures, the individual must still seek a doctor without delay so that a thorough diagnosis can be carried out and appropriate treatment can be provided immediately.
If you will enroll in a first aid course, you will learn all the basics when it comes to first aid care. These measures are not only applicable to this type of injury, but also other similar injuries that would require initial treatment before medical care can be provided.
Preventive measures
Some individuals are more susceptible to have a subluxation of the wrist than others. Those who are involved in rigorous sports or activities must protect their wrists by using elastic bandage wraps. In case of recurrent subluxations, it can be prevented as long as the adequate length of time for the injured wrist to properly heal is taken into consideration. Take note that this period typically involves total immobilization of the joint, oftentimes with the help of a plaster cast.
