Shoulder Dislocation Treatment in Schaumburg, IL
Shoulder Dislocation
The shoulder is the most mobile joint in the body — and as a result, it is also the most commonly dislocated. A shoulder dislocation occurs when the ball of the upper arm bone (humerus) is forcibly driven out of its shallow socket in the shoulder blade, causing immediate and severe pain. Both partial dislocations (subluxations) and complete dislocations cause pain and instability, and both require prompt evaluation and treatment to reduce the risk of recurrence and long-term complications.
At Barrington Orthopedic Specialists, our experienced, board-certified orthopedic shoulder specialists can assess your dislocation, guide your recovery, and help determine whether surgical stabilization is needed to protect your shoulder long-term:

Shoulder Dislocation: Diagnosis & Treatment
The shoulder joint is a ball-and-socket joint in which the rounded head of the humerus (upper arm bone) sits within the glenoid fossa — a shallow depression in the shoulder blade. Because the socket is so shallow, the shoulder relies on several structures for stability: the labrum (a fibrous ring of cartilage that deepens the socket), the joint capsule, the ligaments, and the rotator cuff muscles and tendons. The inherent shallowness of the socket is what makes the shoulder so mobile — and what makes it the most commonly dislocated joint in the body.
Types of Shoulder Dislocation
Dislocations are described by the direction in which the humeral head moves:
- Anterior dislocation — The humeral head moves forward in front of the joint. This accounts for 90% or more of all shoulder dislocations and typically results from a fall on an outstretched arm or a blow to an abducted, externally rotated arm.
- Posterior dislocation — The humeral head moves backward toward the shoulder blade. Less common, and often associated with seizures or electric shock.
- Inferior dislocation (Luxatio Erecta) — The humeral head displaces downward below the joint. Rare and typically high-energy.
- Intrathoracic dislocation — The humeral head becomes trapped between the ribs. Very rare.
A subluxation is a partial dislocation in which the humeral head partially exits the socket but is not fully displaced. Both partial and complete dislocations cause pain and instability, and approximately 25% of shoulder dislocations or instability injuries are associated with fractures.
Immediate Treatment: Reduction
The first priority after a shoulder dislocation is reducing the joint, returning the humeral head to its normal position in the socket. This procedure is called a closed reduction and is performed by a physician. Severe pain typically stops almost immediately once the shoulder is back in place. X-rays are taken before and after reduction to confirm position and assess for associated fractures.
Nonsurgical Treatment
Following reduction, the shoulder is immobilized to allow the damaged soft tissues to heal and to reduce the risk of repeat dislocation:
- First-time dislocations may be immobilized in an external rotation position, which some studies suggest can lower recurrence risk by holding the torn labrum in a more favorable position for healing
- Recurrent dislocations are often immobilized in a standard sling position
The total duration of immobilization varies and must balance the need for stability against the risk of prolonged stiffness and loss of motion. After immobilization, a structured physical therapy program restores motion and strengthens the rotator cuff to provide dynamic stability to the joint.
Surgical Treatment
Surgery is recommended when:
- The shoulder dislocates recurrently, particularly in younger and active patients where the risk of recurrence without surgery is high
- A significant labral tear (Bankart lesion) or bone loss that is unlikely to heal well with conservative care has been identified
- Associated fractures or other structural damage require operative repair
Surgical stabilization — most commonly performed arthroscopically as an outpatient procedure — involves reattaching the torn labrum to the glenoid rim and tightening the stretched ligaments, restoring the normal anatomy and stability of the shoulder.

Frequently Asked Questions
What Causes a Shoulder Dislocation?+
Shoulder dislocations most commonly result from a fall onto an outstretched arm or a direct blow to the shoulder while the arm is in a position of abduction and external rotation — such as during a tackle in contact sports or a fall during skiing or cycling. High-energy trauma is also a common cause. Posterior dislocations are less common and more often associated with seizures, electric shock, or a forceful blow to the front of the shoulder. Recurrent dislocations can occur with increasingly minor trauma as the supporting structures become progressively stretched and damaged.
What Are the Symptoms of a Shoulder Dislocation?+
Symptoms of a shoulder dislocation include:
- Intense, immediate pain in the shoulder
- A visible deformity or abnormal contour of the shoulder
- Swelling and bruising around the joint
- Inability to move the arm normally
- Numbness or tingling in the arm or hand if nearby nerves are stretched
- Weakness in the shoulder or arm
- A feeling that the shoulder is "out of place"
In some cases, the dislocation may also tear ligaments or tendons in the shoulder or damage nearby nerves, which is why prompt medical evaluation is important.
How Is a Shoulder Dislocation Treated?+
Immediately following a dislocation, the shoulder must be reduced — the humeral head is guided back into the socket by a physician in a process called closed reduction. This is typically done with muscle relaxation (sedation or local anesthetic) and provides rapid pain relief. After reduction, X-rays confirm proper positioning and assess for fractures. The shoulder is then immobilized in a sling, and a rehabilitation program gradually restores motion and strength. For patients at high risk of recurrence — particularly younger, active individuals — the decision about whether surgical stabilization is needed is made based on the severity of the injury and the patient's activity level and goals.
What Is the Risk of Recurrence After a Shoulder Dislocation?+
Recurrence risk is strongly influenced by age at the time of first dislocation. Young, active patients — particularly those under 25 — have recurrence rates that can range from 50% to 70% or higher without surgical stabilization, as the torn labrum and ligaments are unlikely to heal in a position that restores normal stability. Older patients and those who are less athletically active have a lower recurrence risk and are more likely to do well with conservative management. Activity level, sport participation, and the degree of structural damage also influence the decision about surgery.
When Should I See a Doctor After a Shoulder Dislocation?+
You should seek prompt medical evaluation after any shoulder dislocation — even if the shoulder appears to have reduced spontaneously or has been reduced in the field. X-rays are needed to confirm proper reduction, identify associated fractures, and guide further management. After the acute episode is treated, a follow-up appointment with a shoulder specialist is important to assess the extent of soft tissue damage, discuss recurrence risk, and plan the most appropriate rehabilitation and — if indicated — surgical strategy.
