Have you felt severe pain in your shoulder after falling or being hit? You might have an acromioclavicular dislocation. This is a serious injury to the joint between the collarbone and shoulder blade. It often affects young people who do contact sports or risky activities.
This injury occurs when the ligaments in the joint are stretched or torn. Thus, the clavicle and acromion are abnormally separated. It is common in contact sports or with strong shoulder movements. A hard fall on a bicycle, motorcycle, or in sports such as rugby, football or judo are usually the causes.
It is categorized into three grades according to the extent of the injury and the displacement of the bones. Physical examination will reveal discomfort, deformities, and a sign when palpating the displaced collarbone . X-rays and MRIs may also be done to see more accurate lesions.
Treatment may be conservative or require surgery, depending on the patient’s injury and lifestyle. Recovery can take anywhere from weeks to months. Rehabilitation with a specialized physiotherapist is essential to heal well.
Acromioclavicular dislocation is a common injury to the shoulder. It happens when ligaments are stretched or torn. This causes the bones to move out of their normal place.
It exists in varying degrees of severity depending on the damage. They range from mild stretches to complete ligament tears:

Acromioclavicular dislocation is caused by high-energy trauma. Falling on the side of the shoulder is the most common cause. Suffering from it is common in cyclists, footballers and rugby players. It can also occur due to falls or traffic accidents.
It is a common injury among contact athletes and combat sports. To prevent it, it is recommended to strengthen the shoulder muscles. Also practice safe techniques, use protection and be in shape.
Acromioclavicular dislocation is due to several causes. Direct blows to the shoulder are quite frequent. Such damage occurs from falls, crashes, or injuries to the acromioclavicular joint area. Direct impacts are the main source of this injury. This includes falls on the shoulder or hard crashes, especially in competitive sports.
A hard blow or fall to the shoulder can lead to a dislocation. These events happen at times such as accidents, falls, or when playing contact sports.
Athletes face this injury a lot, especially in contact sports. Games such as American football, rugby, hockey and martial arts represent more risk due to the blows and forces involved.
Acts such as suddenly twisting the arm, or stretching it too far, can also dislocate the joint. This can happen in sports activities or at work when lifting heavy things.
Grade I
Grade II
Grade III
Simple stretching of the AC ligaments, no actual separation
AC ligament rupture and coracoclavicular stretching
Complete rupture of the AC and coracoclavicular ligaments, noting a deformity in the shoulder
However, it is possible to reduce the risks of this injury. This is achieved with increased muscle tone, appropriate techniques in sports and the use of protections.
Acromioclavicular dislocation causes symptoms ranging from mild to severe. Severe shoulder pain is very common, especially in a grade III dislocation. In this one, the AC and coracoclavicular ligaments are completely torn. This pain may be worse when moving and reaching the arm.
Patients also feel swelling and see a lump in their shoulder. These signs signal tissue damage and fluid buildup. When the injury is very severe, the collarbone can be clearly separated from the acromion .
Acromioclavicular dislocation limits arm movement drastically. Because of this, doing normal tasks can be difficult or painful.
A common sensation is that of having a loose or unstable shoulder. This is often accompanied by weakness in the muscles. Thus, lifting heavy objects becomes complicated.
Symptoms can vary depending on the degree of the injury. I would choose from a simple stretch in grade I to breaks in grade II. When in doubt, it is crucial to seek experienced medical help. Only in this way can an accurate diagnosis and effective treatment be obtained.
To find out if a person has acromioclavicular dislocation, the doctor does a clinical evaluation and physical exam. He will look for symptoms such as severe shoulder pain, enlargement, pain when touching, little movement, odd shape, and weak muscles.
To confirm the diagnosis, your doctor may order additional tests, such as X-rays, MRIs, and ultrasounds. These techniques help to clearly see the distance between the collarbone and the acromion. They also show if there is damage to soft tissues, such as ligaments and tendons.
Acromioclavicular dislocation is divided into six types according to the Rockwood classification. It ranges from type I (mild) to type VI (very rare):
In addition to imaging tests, there are clinical tests that can help diagnose acromioclavicular dislocation. For example, the adduction test against resistance is good for detecting the problem. He has a 77% success rate. Another useful test is O’Brien’s, which shows 95% accuracy in ruling out the disease. These tests help your doctor know which treatment is best.
It is key to make an accurate and timely diagnosis. This allows you to apply a correct treatment and avoid long-term problems. Some of the preventable complications include constant instability, arthritis, chronic pain, and movement limitations. Using ultrasound can help monitor how the lesion is improving. It also guides when it is necessary to do treatments such as infiltration or surgeries that are minimally invasive.
The first option for treating acromioclavicular dislocation is conservative treatment. It is mainly used in grade I and II injuries. The goal is to take away the pain, lower the swelling , and help the shoulder function well again.
At first, it’s important to rest your shoulder and keep it protected. Avoiding activities that cause pain or stretch the joint a lot helps. Wearing a sling for a few weeks gives support and stability to the shoulder as it works.
Applying ice helps reduce swelling and pain. It is good to do this several times a day in the first hours of pain. After 2 or 3 days, the heat helps move blood better, loosen muscles, and remove stiffness.
Your doctor may prescribe pain relievers and NSAIDs for pain and swelling. They help you feel more comfortable and promote recovery. It is vital to follow the doctor’s instructions and monitor any side effects.

In summary, the non-invasive treatment of acromioclavicular dislocation uses combined strategies such as rest, medications, and rehabilitation. While it has been shown to offer similar results to surgery, each situation should be evaluated separately. Factors such as the patient’s age and the extent of the injury are crucial when deciding on the most appropriate treatment.
Sometimes, a severe acromioclavicular dislocation needs surgery. This occurs when there is a lot of instability or deformity. In these cases, doctors repair the damaged ligaments and return the joint to its proper place. Surgical treatment is common, especially for acute shoulder injuries.
More serious injuries, such as types IV-VI, need surgery soon, about 2 to 3 weeks after the injury. But, for type III injuries, some believe that surgery is not always necessary. They say that treatment without surgery can work just as well, but it puts the patient at less risk and takes longer to recover.
Deciding to operate on an acromioclavicular dislocation depends on several aspects, including the severity of the injury or whether there is instability or deformity. It affects men more in their second decade of life. One study showed that intervening in type III lesions can have positive results. This was done in 67 patients with an average age of 34 years.
Common causes of these injuries are falls, car accidents, and sports. Surgery often involves repairing ligaments with techniques such as sutures or implants. A technique known as a plate-hook is effective in many cases, but sometimes a second operation is needed to remove the implant. Another option is the use of very strong sutures to reconstruct the ligaments.

After surgery, there is a time of rehabilitation. This stage is vital for regaining strength and movement of the shoulder. Each person recovers differently, so the process is tailored to their needs.
One study showed that most patients had very good outcomes within three months of surgery. There was one case with a complication, but that did not affect the overall success of the treatment.
Acromioclavicular dislocation is a common injury in contact or combat athletes. Up to 7% of those affected will have symptoms such as pain and limitation of movement. It is vital to get an accurate diagnosis to know the severity. There are three degrees of injury: I, II, and III.
Each sport requires a different type of recovery. The length of the process varies greatly. It depends on how severe it is and how the person responds. It is key to do specialized rehabilitation with an expert physiotherapist. Recovery is divided into several stages, from protecting the injury to returning to activity step by step.
When returning to sport, using bandages or shoulder supports can be helpful. But they should always be evaluated by specialists. Rehabilitation must be cared for and adapted. This is to ensure a safe return to racing. Acromioclavicular joint injuries are common in young cycling or wrestling athletes.
Acromioclavicular dislocation occurs at the junction of the clavicle and acromion. It is an injury where the ligaments are stretched or torn. This causes the bones to move out of their normal place.
It can be caused by a blow to the shoulder or by a fall. It also occurs in contact sports or with sudden movements of the arm.
You feel a strong pain in your shoulder. In addition, there is swelling and the shoulder looks deformed. You notice that the arm does not move well and that the shoulder seems unstable.
The traumatologist does a physical examination. Sometimes tests such as X-rays or MRIs are needed to confirm and see the severity of the injury.
It is based on resting and protecting the shoulder. Hot and cold therapies are also used. Medicines help remove pain and inflammation. In addition, rehabilitation is done with exercises for the muscles and mobility of the shoulder.
Surgery may be needed if the injury is severe or if there are problems with instability or deformity in the shoulder. In the operation, the ligaments are fixed or the joint is reconstructed.
It is key to obtain an accurate diagnosis and assess the severity of the injury. Rehabilitation must be specific. The time to return to sports varies depending on the sport and the response of each person.
