The shoulder is a complex joint that offers an impressive range of motion, but this very flexibility is accompanied by increased susceptibility to injury and destabilization. Shoulder instability is one of the most common conditions, especially in young and athletically active populations.

The shoulder joint functions as a “ball and socket” joint, that is, as a sphere (the head of the humerus) that moves within a concave surface (the glenoid). This structure gives the shoulder the greatest possible range of motion in the entire human body. However, for this joint to be functional and stable, many factors are required to ensure that the head of the humerus remains firmly in the glenoid during movements.

What is shoulder instability?

When the mechanisms that hold the head of the humerus in the socket fail to function properly, the joint becomes unstable. This means that the head can move excessively or even completely out of place, causing what is called a shoulder dislocation.

Instability can be due to:

• Injuries (e.g. falls, sudden movements)
• Overuse and strain (such as in athletes who perform repetitive movements)
• Weakness of the muscle base that supports the joint

What are the symptoms?

Patients with shoulder instability usually experience:

• Severe pain in the shoulder area, especially during movements
• Feeling of looseness in the joint
• Limited movement
• In some cases, actual dislocations, where the shoulder comes out of its position either forward or backward.

This condition creates great difficulty in everyday life, as even and simple movements can become painful and dangerous.

How is shoulder instability treated?

When a dislocation occurs, the first step is immediate reduction, that is, the repositioning of the humeral head into the glenoid cavity. This procedure is usually performed in emergencies.

After reduction, the patient undergoes a detailed imaging examination (e.g. MRI) to assess the damage and the extent of the problem. Restoring normal shoulder function is the next and most important step.

Modern surgical techniques:

Arthroscopy

In recent years, the treatment of shoulder instability has improved significantly with the introduction of arthroscopy, a minimally invasive method. Through small holes, the surgeon inserts a small camera and specialized tools into the joint, allowing for precise diagnosis and treatment. A common problem in patients with instability is the detachment of the labral cartilage (an important structure that helps stabilize the joint). With arthroscopy, this cartilage is mobilized and repositioned in its correct position with special sutures and clasps, which can be metallic or absorbable, depending on the needs and age of the patient.

The operation and recovery

Arthroscopic operations for shoulder instability are usually performed as a day-case, meaning the patient enters the hospital in the morning and returns home in the afternoon.

After surgery, a specific rehabilitation protocol follows:

• Three weeks of immobilization with a special splint to protect the joint
• From the fourth week, gentle physiotherapy with passive range of motion exercises
• From the sixth week, active exercises and gradual muscle strengthening
• Full return to activities depends on the patient’s activity level, with athletes following more
• specialized protocols.

What are the chances of recurrence?

Recovery of the joint through modern techniques is considered definitive. However, there is always a small chance of recurrence, especially in athletes or people with intense physical activity who may suffer a new injury.

In these cases, there are now advanced treatment methods that can provide a solution.

The importance of expertise and equipment

The success of the treatment depends not only on technology but also on the experience of the doctor. Surgical repair of shoulder instability requires expertise and modern logistical equipment, which is available in specialized centers.

Shoulder instability is a serious condition that affects the quality of life of many people. Fortunately, advances in medicine and surgery today offer safe and effective solutions, aimed at restoring normal joint function and returning to normal activities, daily and sports activities.

With proper diagnosis, timely treatment and specialized care, shoulder instability can be completely treated, giving the patient freedom of movement again, without pain and restrictions.
