The shoulder joint is the most mobile in the body. It performs a wide range of movements and is associated with its ball shape.
The joint consists of the head of the humerus and the joint hollow of the scapula, which are in contact with each other.
The hollow of the scapula is a flat fossa, which is several times smaller than the joint head itself. When the position of the head is disturbed during movement, the shoulder is dislocated, so says Dr. Denis Slinkin.
A dislocated shoulder or dislocation is a frequent injury and is encountered predominantly by athletes or people who live active lives. In fact, the surface of the head of the bone is displaced from the joint socket. At this point, the person feels intense pain and can no longer move the damaged arm.
Dr. Denis Slinkin claims that sometimes a circular movement of the arm is enough to cause injury, which seems very simple to us.
The usual shoulder sprains can be different
Among all types of sprains, the shoulder is over 50%. It seems that dislocation is a minor injury, but there are cases when it leads to various injuries or complications, so says Dr. Denis Slinkin.
Let’s look at the forms and types of sprains and how they happen:
- The anterior is one of the most common forms of this injury. In this case, the joint head falls forward, the arm is turned out and pulled aside. The joint head may fall out under the beak-shaped portion of the scapula or under the collarbone. This is separated from the front connecting sprain and the subclavian sprains.
- The posterior shape is less common and occurs when the person falls, putting his hands forward. In this case, the cartilaginous roller is torn off in the posterior region of the joint socket.
- The lower shape is an armpit dislocation. In this case, the head is displaced and falls down the humerus. In this case, the person will not be able to lower the arm, will experience severe pain and must keep the damaged limb raised.
- The usual dislocation of the shoulder is due to the unstable condition of the joint, which can dislodge even under the slightest of stresses. Sometimes this condition is caused by complications of primary dislocation, incorrect treatment or rehabilitation after injury.
There is also partial dislocation. In this case, the head remains partially in the joint cavity.
In addition, depending on the time elapsed after the dislocation is isolated:
- Fresh sprains: Up to three days;
- Fresh sprains: three days to three weeks;
- The older ones are more than three weeks.
