Ακρωμιοκλειδική αστάθεια

Acromioclavicular instability is a condition that affects the joint between the acromion (a bony projection on the scapula) and the clavicle (collarbone). This joint is essential for the proper functioning of the ώμος, as it allows for a wide range of motion. However, when the ligaments that support this joint become stretched or torn, it can lead to instability and pain.

Acromioclavicular instability can occur due to various reasons, such as trauma, repetitive overhead activities, or degenerative changes in the joint. Traumatic injuries, such as falls or direct blows to the shoulder, are the most common causes of acromioclavicular instability. These injuries can result in a sprain or tear of the ligaments, leading to instability and shoulder pain.

Causes of Acromioclavicular Instability

There are several factors that can contribute to the development of acromioclavicular instability. One of the primary causes is trauma to the shoulder, such as a fall or a direct blow. These injuries can cause the ligaments that support the acromioclavicular joint to stretch or tear, resulting in instability.

Repetitive overhead activities, such as throwing or weightlifting, can also contribute to the development of acromioclavicular instability. These activities place significant stress on the ώμος joint, leading to wear and tear of the ligaments over time.

Additionally, degenerative changes in the joint can also cause acromioclavicular instability. As we age, the cartilage in our joints naturally wears down, making them more susceptible to injury and instability.

Symptoms of Acromioclavicular Instability

The symptoms of acromioclavicular instability can vary depending on the severity of the condition. Common symptoms include:

• Shoulder pain: Pain in the shoulder joint is one of the primary symptoms of acromioclavicular instability. The pain may be mild to severe and can worsen with certain movements or activities.
• Shoulder weakness: Instability in the acromioclavicular joint can result in shoulder weakness. You may notice a decrease in your ability to lift or carry objects, as well as difficulty performing overhead activities.
• Swelling and tenderness: Inflammation and swelling around the acromioclavicular joint are common symptoms of instability. The area may be tender to the touch and appear swollen or bruised.
• Clicking or popping sensation: Some individuals may experience a clicking or popping sensation in the shoulder joint when moving their arm. This can be a sign of joint instability.

Treatment Options for Acromioclavicular Instability

The treatment options for acromioclavicular instability will depend on the severity of the condition and the individual’s specific needs. In mild cases, non-surgical treatments may be sufficient, while more severe cases may require surgical intervention.

Non-surgical treatments for Acromioclavicular Instability

Non-surgical treatment options for acromioclavicular instability include:

• Ανάπαυση και ακινητοποίηση: Giving the joint time to heal and avoiding activities that exacerbate the symptoms can help reduce pain and promote healing. Immobilization, such as wearing a sling, may be recommended to support the joint during the recovery process.
• Φυσικοθεραπεία: A physical therapist can guide you through exercises and stretches to improve the strength and stability of the shoulder joint. They may also use techniques such as ultrasound or electrical stimulation to reduce pain and inflammation.

Surgical options for Acromioclavicular Instability

Surgical intervention may be necessary for individuals with severe acromioclavicular instability or those who do not respond to non-surgical treatments. The specific surgical procedure will depend on the extent of the instability and any associated injuries.

Common surgical options include:

During a reconstruction surgery, the damaged ligaments are repaired or replaced with grafts to restore stability to the joint. This procedure is typically performed arthroscopically, using small incisions and a camera-guided instrument.

In some cases, the acromioclavicular joint may need to be stabilized using screws, plates, or other hardware. This is often done in conjunction with ligament reconstruction to provide additional support.

Rehabilitation and Recovery after Acromioclavicular Instability Surgery

Following surgery for acromioclavicular instability, a rehabilitation program will be essential to regain strength and restore full function to the shoulder joint. The rehabilitation process typically involves a combination of exercises, manual therapy, and progressive strengthening.

During the initial stages of rehabilitation, the focus will be on reducing pain and inflammation, improving range of motion, and gradually reintroducing functional movements. As the healing progresses, exercises to strengthen the muscles around the shoulder joint will be incorporated.

Physical therapy sessions may be scheduled several times a week initially, and then gradually reduced as the individual gains strength and stability. It is important to follow the prescribed rehabilitation program and attend all scheduled therapy sessions to optimize recovery.

Preventing Acromioclavicular Instability

While some cases of acromioclavicular instability are the result of traumatic injuries that may be difficult to prevent, there are steps you can take to reduce your risk:

–Strengthening exercises: Regularly performing exercises that target the muscles around the shoulder joint can help improve stability and reduce the risk of injury.

-Proper technique: When engaging in activities that involve overhead movements, such as throwing or weightlifting, it is important to use proper technique and avoid placing excessive stress on the shoulder joint.

–Gradual progression: When starting a new exercise or activity, gradually increase the intensity and duration to allow your body to adapt and minimize the risk of overuse injuries.

–Protective gear: If you participate in contact sports or activities with a high risk of shoulder injury, consider wearing appropriate protective gear, such as shoulder pads or braces.
