What are the rear labral tears?

The rear labral tears are injured by a specific type of cartilage found only in the joints of the body sleeves: shoulders and hips. The tear of the labral arm is more common than a similar tear of the hip, due to the greater use of the upper limbs in general and the larger range of movement, which is usually required to joint in everyday use. The Labrum itself is a special type of cartilage surrounding the drawer that is designed to distinguish the joint and increase the depth of the glanoid arm socket, that the ball - or the bones of the upper arm - lies inside, increasing the overall stability of the joints. At the back or rear aspect of the labrum there are rear labral tears. They are usually classified as superior labrum front than rear (slap) Tear or rear labral tear with impact.

Slaps are one of the types of rear labral tears, and include the upper aspect of the Labrum from the front back. These tears are classified into four categories in a veilIsity on the degree of injury, specific aspects of the shoulder anatomy and the expected level of intervention repair. One of the four categories of tears of the slap is further divided into three types, depending on the area or areas of injury, starting with the front of the arm and progressing back. The rear labral tears classified as tears of slap also include the front or upper aspect of the labrum, and thus the area where the biceps muscle head is connected to the arm. They most often affect individuals who have to use their head movement repeatedly, such as baseball pitchers or wooden helicopters that use ax.

The rear labral tears can also often occur with the impact or clamping of the rotator coat of the shoulder. This impact occurs less frequently than tears of slap, but can also be seen in athletes, especially footballyers. The rear labral tears with impact affect the stability of the shoulder due to the connection of the rotator cuff. In fact, a rotator cuff consists of four separate muscles that work togetherIt is eaten to ensure the stability and flexibility of the shoulder joint. The complete dislocation of the humerus from the shoulder is rare with the injury of the rotator cuff, but the subaxation - instability perceived with movement - is a common complaint.

Despite their specific classification, the rear labral tears share some similar symptoms. Shoulder pain is usually described as deep or sore and is found in the joint area itself. Other symptoms include reports of subjective instability or specific tension or catch when repeating the typical movement of the shoulders. Diagnosis usually requires scanning MRI or CT, although smaller tears may require arthroscopic evaluation.
