Shoulder Impingement Treatment Options

The shoulder is a complex joint made up of bones, muscles, and tendons that allow a wide range of motion. Impingement occurs when the rotator cuff tendons are compressed under the acromion, a bony projection of the shoulder blade. This compression irritates the tendons and bursa, leading to inflammation and pain with movement. Over time, chronic impingement can cause tendinitis or even partial rotator cuff tears. Common symptoms include pain when lifting the arm overhead, weakness, stiffness, or discomfort when lying on the affected shoulder.

Accurate diagnosis is essential for effective treatment. At Ortho Illinois, our specialists begin with a detailed review of your medical history, physical examination, and imaging studies such as X-rays or MRI scans to evaluate the bones, tendons, and surrounding soft tissues. This helps determine the underlying cause of impingement—whether it is due to bone spurs, rotator cuff inflammation, or structural abnormalities of the acromion. Once the cause is identified, an individualized treatment plan is created based on the severity of symptoms and the patient’s activity level.

Most cases of shoulder impingement can be successfully treated without surgery. Early intervention focuses on reducing pain and inflammation while restoring shoulder strength and flexibility.

• Activity modification and rest – Avoiding or modifying activities that aggravate the shoulder, such as overhead reaching, heavy lifting, or repetitive motions, allows inflammation to subside. Temporary rest is often combined with gradual reintroduction of motion under the guidance of a specialist or physical therapist.
• Nonsteroidal anti-inflammatory medications (NSAIDs) – Oral anti-inflammatory medications such as ibuprofen or naproxen can help reduce pain and swelling in the early stages of impingement. These medications provide short-term relief, especially when used in combination with other conservative measures.
• Ice and Heat Therapy – This works to reduce inflammation and pain and improve blood flow.
• Physical therapy – Rehabilitation plays a central role in treating shoulder impingement. A customized physical therapy program focuses on stretching tight shoulder structures, strengthening the rotator cuff and scapular muscles, and improving posture and shoulder mechanics. By restoring balanced muscle function, therapy helps prevent future impingement episodes. Therapeutic exercises may include resistance band work, range-of-motion exercises, and postural training.
• Corticosteroid injections – If pain persists despite conservative treatment, corticosteroid injections may be recommended. These injections deliver powerful anti-inflammatory medication directly into the subacromial space to relieve pain and swelling, allowing patients to engage more effectively in physical therapy. Injections are typically used as part of a broader treatment strategy and are spaced appropriately to avoid potential tendon weakening.
• Regenerative medicine therapies – For select patients, regenerative treatments such as platelet-rich plasma (PRP) injections may be considered to promote healing of the inflamed tendons and bursae. These biologic therapies use the patient’s own blood components to stimulate tissue repair and reduce inflammation, although their effectiveness can vary based on the severity of the condition.

When nonsurgical methods fail to provide adequate relief after several months, surgical intervention may be necessary to create more space for the rotator cuff and relieve pressure on the tendons.

• Arthroscopic shoulder impingement surgery – This minimally invasive procedure is the most common surgical treatment for shoulder impingement. During the surgery, small instruments and a camera are inserted through tiny incisions to remove inflamed bursal tissue and shave away small bone spurs from the underside of the acromion. This helps eliminate friction between the bone and the rotator cuff tendons. Arthroscopic surgery generally results in less postoperative pain and a quicker recovery compared to open procedures.
• Acromioplasty and distal clavicle resection – In some patients, especially those with bone spurs or arthritis at the acromioclavicular (AC) joint, an acromioplasty may be performed to reshape the acromion and relieve impingement. If the AC joint contributes to pain or inflammation, a distal clavicle resection may also be done to remove a small portion of the collarbone. Both procedures can be completed arthroscopically and are aimed at restoring smooth, pain-free shoulder movement.
• Rotator cuff repair – If imaging reveals a partial or full-thickness rotator cuff tear resulting from long-standing impingement, surgical repair of the tendon may be performed at the same time. Repairing the tendon restores function and prevents further degeneration.

After surgery, a structured rehabilitation program is essential for optimal recovery. Early motion exercises begin soon after surgery to prevent stiffness, followed by gradual strengthening as healing progresses. Most patients can return to normal daily activities within several weeks, although full recovery and return to sports or heavy labor may take a few months depending on the procedure performed.
