Shoulder Dislocation

The shoulder is a ball-and-socket joint that provides an exceptional range of motion, allowing the arm to move in many directions. This flexibility comes at the expense of stability, making the shoulder particularly susceptible to dislocation.

A shoulder dislocation occurs when the ball of the upper arm bone (humerus) is forced out of the shoulder socket (glenoid). The injury can damage surrounding muscles, ligaments, cartilage, and nerves, often requiring prompt medical attention. At Fox Valley Orthopedics, we provide comprehensive treatment options designed to relieve pain, restore mobility, and help patients return to their normal activities.

What Is a Shoulder Dislocation?

A shoulder dislocation occurs when the humeral head separates from the glenoid socket. The injury is typically caused by significant force and often results in immediate pain and loss of function.

When the shoulder dislocates, surrounding structures may also be injured, including:

• Ligaments
• Tendons
• Cartilage
• Muscles
• Nerves
• Bone

Because these associated injuries can affect long-term stability, a thorough orthopedic evaluation is important after a shoulder dislocation.

What Types of Shoulder Dislocations Are There?

Shoulder dislocations are classified based on the direction the humeral head moves out of the socket.

Anterior Shoulder Dislocation

Anterior dislocations account for the vast majority of shoulder dislocations. In this injury, the humeral head moves forward out of the socket.

These injuries commonly occur during:

• Falls
• Sports injuries
• Collisions
• Trauma involving an outstretched arm

Posterior Shoulder Dislocation

Posterior dislocations are less common and occur when the humeral head moves backward out of the socket.

These injuries may be associated with:

• Seizures
• Electrical injuries
• Significant trauma

Inferior Shoulder Dislocation

Inferior dislocations are rare but can occur when the arm is forced overhead, causing the humeral head to move downward out of the socket.

What Causes a Shoulder Dislocation?

Most shoulder dislocations result from trauma or sudden force applied to the joint.

Common causes include:

• Falls
• Sports-related injuries
• Football, wrestling, hockey, and other contact sports
• Motor vehicle accidents
• Workplace injuries
• Direct blows to the shoulder
• Sudden twisting motions
• Previous shoulder instability

Patients who have experienced one dislocation may be at higher risk of future shoulder instability or recurrent dislocations.

What Are the Symptoms of a Shoulder Dislocation?

Symptoms usually occur immediately after the injury and can be severe.

Common signs and symptoms include:

• Severe shoulder pain
• Visible shoulder deformity
• Inability to move the arm normally
• Swelling around the shoulder
• Bruising
• Weakness in the arm
• Sensation that the shoulder has “popped out”
• Numbness or tingling in the arm or hand
• Muscle spasms around the shoulder

Many patients instinctively hold their arm against their body to minimize discomfort.

How Is a Shoulder Dislocation Diagnosed?

Diagnosing a shoulder dislocation begins with a comprehensive orthopedic evaluation.

Diagnostic evaluation may include:

• Review of symptoms and injury history
• Physical examination
• Assessment of shoulder stability
• Evaluation of nerve and circulation function
• X-rays to confirm the dislocation
• MRI imaging to assess soft tissue damage
• CT scans for complex injuries or fractures

Imaging studies help identify associated injuries and guide treatment recommendations.

How Is a Shoulder Dislocation Treated?

Many first-time shoulder dislocations can be treated without surgery.

Nonsurgical treatment options may include:

• Closed reduction to reposition the joint
• Sling immobilization
• Activity modification
• Pain management
• Physical therapy
• Strengthening exercises
• Range-of-motion rehabilitation

Rehabilitation plays a critical role in restoring shoulder stability and reducing the risk of future dislocations.

When Is Surgery Recommended for Shoulder Dislocations?

Surgery may be recommended when:

• The shoulder repeatedly dislocates
• Significant ligament damage is present
• A labral tear has occurred
• Bone loss or fractures are involved
• The patient participates in high-risk sports
• Conservative treatment fails to restore stability

Surgical options may include:

• Arthroscopic shoulder stabilization
• Labral repair
• Ligament reconstruction
• Bone grafting procedures
• Shoulder stabilization surgery

The goal of surgery is to restore joint stability and prevent future dislocations.

What Does Shoulder Dislocation Recovery Look Like?

Recovery depends on the severity of the injury, the presence of associated damage, and whether surgery is required.

Patients treated nonsurgically typically undergo a period of immobilization followed by progressive rehabilitation.

Recovery may include:

• Sling use
• Activity restrictions
• Physical therapy
• Range-of-motion exercises
• Strengthening programs
• Gradual return to sports and work activities

While many patients return to normal activities within a few months, full recovery timelines vary depending on the injury and treatment plan.

What Complications Can Occur if a Shoulder Dislocation Is Left Untreated?

Without proper treatment, shoulder dislocations can lead to ongoing instability and other complications.

Potential complications include:

• Recurrent shoulder dislocations
• Chronic shoulder instability
• Labral tears
• Rotator cuff injuries
• Cartilage damage
• Arthritis
• Nerve injury
• Reduced shoulder function
• Chronic pain

Early treatment and rehabilitation can significantly reduce the risk of long-term issues.
