The acromioclavicular formation is located in the shoulder region and joins two important bones (the acromion and the clavicle) through a series of ligaments.
As a general rule, we can raise our arms above the head thanks to this articulation. It also coordinates other movements that involve the shoulder, such as the rotation of the upper limbs. Thus, this region can receive a strong blow or traumatism because of a fall. On the other hand, the scapula, another bony component, is displaced beyond the
However, the clavicle, which is attached to it, is not able to follow the scapula and the tendons that join them eventually tense. Therefore, the tendons end up badly damaged and can break completely.
Some specialists compare the acromioclavicular joint with a body fuse. This is because it absorbs the energy of the blow and damage the tendons that form it instead of injuring other more vital internal structures.
Symptoms of acromioclavicular dislocation
The patient may suffer a series of alterations or symptoms associated with this disorder . Among the most common we find:
- Intense that is located just above the joint. Normally the ailment intensifies with the performance of daily movements (especially above the head).
- Deformation or increase of the naked eye volume due to the lifting of the clavicle.
Causes of acromioclavicular dislocation
As a general rule, it is produced by a strong blow or direct on the It occurs more frequently in sports practices, which increase the risk of bodily injury. However, it can happen casually in the home or at work.

For the diagnosis or detection of this pathology, the medical team can use both a physical examination and a combination of other medical tests . In this way, you can identify this alteration and rule out other similar problems. For example, dislocation of the shoulder or glenohumeral joint, which lies between the humerus and the shoulder blade.
In the case of physical examination, the doctor will check the symptoms that the patient may present. Also, a characteristic signal of this injury is “the sign of the key”. In it, the specialist in question can press the raised clavicle of the subject, which moves down and recovers its initial position. Thus, the movements that a piano key can make are imitated.
On the other hand, within the medical tests we include obtaining internal images. In particular, shoulder where the positions of the bones that make up the joint can be seen. Other procedures such as blood or urine tests can also be carried out to exclude other pathologies.
Treatment of acromioclavicular dislocation
The specialists differentiate six different degrees depending on the severity of the injury (a higher degree corresponds to a more serious damage).
- For dislocations of grade I and II cold application is recommended in the area to reduce inflammation. Likewise, the medical team usually recommends the use of analgesics (drugs that calm or reduce pain) and rest during the three weeks after the trauma.
- On the other hand, in dislocations of grade III and IV a surgical intervention is carried out in which the joint is immobilized. In this way, the patient’s medical situation is prevented from worsening. The patient will also rest after the procedure and analgesics will be prescribed to calm him down.
- In the case of grade V and VI dislocations, surgery is also performed as a treatment. For example, you can use the hook plates to reposition the clavicle in the proper position.
Prevention of acromioclavicular dislocation
It is recommended to perform moderate regularly to keep the body in good condition and maintain a good quality of life. If you suffer from any of the symptoms mentioned above, consult your medical team as soon as possible to rule out the presence of pathology.
