What Is Shoulder Instability?

Shoulder instability occurs when the shoulder joint is too loose and frequently slips out of place. The shoulder is a ball-and-socket joint, where the ball (the head of the humerus) fits into the shoulder blade’s socket (the glenoid).

When the ligaments, tendons, and muscles surrounding the shoulder joint are stretched or torn, they can no longer keep the joint in place. This condition can lead to partial or complete dislocations and a sensation of the shoulder “giving out.”

People suffering from shoulder instability often experience pain, weakness, and a limited range of motion. The condition can be a result of trauma, repetitive use, or a structural abnormality of the shoulder.

How Does It Develop?

Shoulder instability can occur in several ways:

• Trauma: The most common cause is a traumatic injury, such as a fall or a sports-related incident that forces the shoulder out of its normal position. Once the shoulder has been dislocated, it becomes more susceptible to repeated dislocations or subluxations (partial dislocations), leading to chronic shoulder instability.
• Repetitive Strain: Another cause of shoulder instability is repetitive overhead movements, often seen in athletes like swimmers, baseball players, or tennis players. These activities can stretch and weaken the ligaments over time, leading to what is known as atraumatic shoulder instability.
• Genetic Factors: Certain genetic factors can also contribute to shoulder instability. Some individuals are born with naturally looser ligaments, making them more prone to dislocations and subluxations. This condition is known as congenital shoulder instability.

How Is It Diagnosed?

Diagnosing shoulder instability begins with a comprehensive medical history and physical examination. Your healthcare provider will ask about your symptoms, previous injuries, and activity level. During the physical examination, the doctor will check for signs of instability, such as abnormal shoulder joint movement or a popping sensation when the shoulder is moved.

Imaging tests like X-rays, MRI, or CT scans may provide a more detailed view of the shoulder joint. These tests help identify any structural damage to the bones, ligaments, or cartilage that may contribute to the instability.

A proper diagnosis is crucial because the treatment plan will vary depending on the severity and type of shoulder instability. If you suspect you have shoulder instability, consult a specialist immediately for an accurate diagnosis.

Treatment Options for Shoulder Instability

Treatment for shoulder instability depends on the extent of the condition and the patient’s lifestyle. Here are some of the standard treatment options:

• • Physical Therapy: In many cases, physical therapy is the first line of treatment. A physical therapist will design a program that includes exercises to strengthen the muscles around the shoulder, improve flexibility, and restore the range of motion. Strengthening the rotator cuff muscles and scapular stabilizers is critical to improving shoulder stability.
  • Surgical Intervention: Surgery may involve repairing or tightening the ligaments and tendons that support the shoulder joint. In some cases, surgeons may perform a procedure called a Bankart repair to reattach the torn labrum to the socket. Another option is the Latarjet procedure, which involves transferring a piece of bone to the shoulder socket to prevent dislocation.
  • Medication: Your doctor may recommend anti-inflammatory medication or injections to reduce pain and inflammation in the shoulder joint.
  • Lifestyle Changes: Making specific lifestyle changes, such as avoiding activities that put excessive strain on the shoulder, can also help prevent further instability.
