Shoulder pain can make everyday movements, such as lifting your arm, reaching overhead or sleeping, uncomfortable and limiting. One of the most common causes of ongoing shoulder pain is shoulder impingement, a condition that occurs when the tendons of the rotator cuff are compressed within the shoulder joint. When nonsurgical treatments are no longer effective, shoulder impingement surgery may be recommended to relieve pain, restore mobility and protect long-term shoulder health.
At Angelo Mattalino, MD in Scottsdale, AZ, we specialize in diagnosing and treating orthopedic conditions like shoulder impingement. Our goal is to help patients return to daily activities, work and sports with improved comfort and confidence.
What Is the Structure of the Shoulder Joint?
The shoulder is one of the most flexible joints in your body. It allows you to lift, rotate, and reach your arm in multiple directions. Having such a wide range of motion requires a great deal of coordination between your bones, tendons, muscles, and ligaments within a relatively small joint space. The rotator cuff tendons pass through a narrow area beneath the acromion (a bony structure on the shoulder blade), where smooth movement depends on adequate space and balanced mechanics.
Because this space is limited, the shoulder is particularly susceptible to impingement. Inflammation, bone changes, or repetitive stress can reduce clearance for the rotator cuff tendons, leading to pain and restricted movement.
What Is Shoulder Impingement?
Shoulder impingement, sometimes referred to as impingement syndrome, occurs when the rotator cuff tendons are pinched between the upper arm bone and the acromion. This area, known as the subacromial space, allows the tendons and bursa to glide smoothly during arm movement.
When this space narrows, the rotator cuff tendons become irritated. Repeated compression over time can lead to tendon damage, weakness and reduced shoulder function.
What Are Common Causes of Shoulder Impingement?
Several factors can contribute to the development of shoulder impingement, including:
- Repetitive overhead motions during sports such as baseball, tennis, swimming or weightlifting
- Occupational activities that involve frequent lifting or reaching
- Poor posture or shoulder mechanics
- Bone spurs on the acromion
- Inflammation or thickening of the bursa
- Muscle weakness or imbalance in the shoulder or upper back
- Age-related wear and tear
These factors may act alone or together.
What Are the Different Types of Shoulder Impingement?
Shoulder impingement is generally classified by its development and progression.
Primary Shoulder Impingement
Primary impingement occurs when structural changes in the shoulder reduce the space available for the rotator cuff tendons. This may be caused by bone spurs on the acromion, thickening of surrounding tissues or age-related changes. Symptoms often worsen gradually and may persist despite rest or activity modification.
Secondary Shoulder Impingement
Secondary impingement is typically related to shoulder instability or muscle imbalance. Weakness or poor coordination of the shoulder stabilizing muscles can cause abnormal joint movement, leading to tendon compression. This type is more common in younger patients and athletes.
What Is Shoulder Impingement Surgery?
Shoulder impingement surgery is performed to relieve pressure on the rotator cuff tendons by increasing space within the subacromial region. The goal is to reduce pain, restore function, and prevent further tendon damage.
Arthroscopic Subacromial Decompression
The most common surgical treatment for shoulder impingement is arthroscopic subacromial decompression. This minimally invasive procedure uses small incisions and specialized instruments to remove inflamed tissue, smooth bone spurs and, if necessary, reshape the acromion. These steps create more room for the rotator cuff tendons to move freely.
Additional Procedures
Depending on the condition of the shoulder, surgery may also include:
- Removal of the inflamed bursa
- Repair of a rotator cuff tear, if present
- Treatment of labral damage or instability
What Are the Benefits of Shoulder Impingement Surgery?
Direct Relief of Tendon Compression
Shoulder impingement surgery addresses the mechanical narrowing that compresses your rotator cuff tendons. By restoring space within your shoulder joint, the procedure helps reduce the irritation and inflammation that cause you pain during movement.
Improved Shoulder Mobility
Removing sources of impingement allows your shoulder to move more freely. Patients often experience improved range of motion during overhead and reaching activities once inflammation subsides and healing progresses.
Protection of the Rotator Cuff
By correcting structural contributors to impingement, surgery helps reduce ongoing stress on your tendon. This may lower your risk of progressive rotator cuff damage or tearing over time.
Reduced Pain With Daily Use
Many patients report a significant reduction in shoulder pain during routine activities such as lifting, reaching and sleeping. Relief from repetitive pain can improve your comfort throughout the day and at night.
Enhanced Response to Rehabilitation
With mechanical impingement resolved, physical therapy becomes more effective. Patients are often able to strengthen supporting muscles more safely and efficiently without reproducing painful symptoms.
Durable Long-Term Results
Shoulder impingement surgery corrects the underlying cause of your issues rather than temporarily masking symptoms. When combined with proper rehabilitation and movement mechanics, results are often long-lasting.
Support for Active Lifestyles
Restoring shoulder function and reducing pain can have numerous downstream benefits. Surgery can help patients return to work, sports and recreational activities with greater confidence and stability.
Shoulder Impingement Surgery vs. Other Treatments
Patients with persistent shoulder pain or limited range of motion often wonder how shoulder impingement surgery compares to other surgical options. The appropriate approach for you depends on:
- The source of your pain
- The condition of your rotator cuff
- The extent of the structural changes that have occured
- Your lifestyle and activity levels
Rotator Cuff Repair
When shoulder impingement has progressed to a rotator cuff tear, tendon repair may be required. This procedure involves reattaching torn tendon tissue to the bone. While rotator cuff repair directly addresses tendon damage, recovery is typically longer, and rehabilitation is more significant than with isolated impingement surgery.
Open Shoulder Surgery
Open shoulder surgery involves a larger incision to access the joint. This approach may be necessary for complex injuries or extensive tissue damage that cannot be safely treated arthroscopically. Recovery tends to be longer due to greater disruption of muscle and soft-tissue structures.
Shoulder Replacement Surgery
Shoulder replacement surgery is reserved for advanced joint damage caused by severe injury or long-standing degeneration. This procedure replaces damaged joint surfaces with artificial components. While effective for pain relief, shoulder replacement is a more extensive surgery with a longer rehabilitation period and is not typically indicated for isolated shoulder impingement.
What To Expect From Shoulder Impingement Surgery
Before
Before surgery, you will undergo a thorough evaluation with Dr. Mattalino, including imaging review and medical clearance. Instructions will be provided regarding medications, fasting and transportation home. Rehabilitation expectations are also discussed in advance.
During
Shoulder impingement surgery is typically performed arthroscopically under general anesthesia. Dr. Mattalino makes small incisions to insert a camera and surgical instruments. The procedure usually takes one to two hours, depending on the extent of treatment required.
After
Most patients return home the same day. The shoulder may be placed in a sling for comfort and protection. Mild swelling and discomfort are common initially and are managed with medication, ice and rest. Physical therapy usually begins shortly after surgery.
Preparing For Shoulder Impingement Surgery
Before your procedure, you will receive personalized preoperative instructions based on your medical history, imaging results, and surgical plan.
You may be asked to:
- Temporarily stop certain medications or supplements that may affect bleeding or anesthesia
- Arrange for a responsible adult to drive you home after surgery
- Avoid eating or drinking after a designated time the night before surgery
- Prepare your home recovery space with pillows, ice packs, and commonly used items within easy reach
If you smoke, stopping smoking before and after surgery can support circulation and tissue healing. Maintaining proper hydration and balanced nutrition in the days leading up to surgery also helps prepare your body for recovery and may improve healing after the procedure.
Frequently Asked Questions About Shoulder Impingement Surgery
Is shoulder impingement surgery painful?
Some discomfort is expected after shoulder impingement surgery, particularly during the first few days as the initial swelling subsides. Most patients describe the pain as moderate rather than severe.
Pain is typically well controlled with prescribed medication, ice therapy and rest. As healing progresses and physical therapy begins, discomfort steadily decreases. Many patients notice meaningful pain relief within the first few weeks compared to their preoperative symptoms.
How successful is shoulder impingement surgery?
Shoulder impingement surgery has a high success rate for reducing pain and improving shoulder function. Most patients experience improved range of motion, increased strength, and greater comfort during daily activities.
Outcomes are especially favorable when surgery is paired with a structured rehabilitation program. Patients who address contributing factors such as posture and muscle imbalance often achieve the best and longest-lasting results.
What are the risks of shoulder impingement surgery?
As with any surgical procedure, shoulder impingement surgery carries some risks. These may include infection, stiffness, nerve irritation, bleeding or incomplete symptom relief. In rare cases, scar tissue formation can limit motion if rehabilitation is delayed or inconsistent.
Serious complications are uncommon, and careful surgical technique combined with proper postoperative care, helps minimize the risk. Dr. Mattalino will review your medical history and discuss any individual risk factors before your surgery.
Can surgery prevent future shoulder problems?
Shoulder impingement surgery reduces pressure on the rotator cuff tendons and helps prevent further tendon irritation or damage. By restoring space within the shoulder joint, surgery lowers the risk of progression to rotator cuff tears.
However, long-term success also depends on maintaining shoulder strength, flexibility and proper movement patterns. Ongoing conditioning and attention to shoulder mechanics are important for preventing future problems.
