Leading Causes of Shoulder Impingement

Shoulder impingement is a common condition that affects individuals in various age groups and activity levels. It occurs when the rotator cuff tendons in the shoulder become irritated and inflamed as they pass through a narrow space, typically under the bony arch of the shoulder blade (acromion). This irritation can lead to pain, weakness and a limited range of motion, severely impacting daily activities.

Understanding Shoulder Impingement

The shoulder is one of the most mobile joints in the body, allowing for a wide range of motion. However, this greater range makes the shoulder susceptible to injuries.

The Orthopedic Research and Reviews journal reveals that “Since it was first described in 1852, shoulder impingement syndrome is believed to be the most common cause of shoulder pain, accounting for 44% to 65% of all shoulder complaints.”

Shoulder impingement can manifest in two primary forms: primary and secondary impingement.

1. Primary Shoulder Impingement: This condition occurs due to anatomical changes, such as bone spurs or degenerative changes in the shoulder mechanics, often leading to compression of the rotator cuff tendons.
2. Secondary Shoulder Impingement: This condition is more common in younger, athletic individuals and is often associated with instability or poor shoulder mechanics, resulting in increased compression during arm movements.

Major Causes of Shoulder Impingement

Impingement can result from a combination of factors, many of which are lifestyle-related.

• Poor Posture: Prolonged periods of slouching or maintaining poor posture can compress the shoulder joints, increasing the risk of impingement. Individuals who spend many hours at desks or engage in tasks that promote forward head and rounded shoulder postures are particularly susceptible.
• Repetitive Overhead Activities: Athletes and individuals engaged in repetitive overhead motions, such as swimmers, baseball players, or gymnasts, are more prone to shoulder impingement. Repeated activities can cause inflammation and swelling in the rotator cuff tendons due to the constant friction they generate.
• Age-related Degeneration: As individuals age, the rotator cuff tendons may develop changes that predispose them to impingement. Degenerative changes can lead to a decrease in thickness and reduced elasticity of these tendons, increasing the likelihood of irritation during arm movements.
• Structural Abnormalities: Some individuals may have bone spurs or variations in the shape of the acromion (the bony process on the shoulder blade) that narrow the subacromial space, increasing the likelihood of impingement. These structural differences can be congenital or develop over time.
• Shoulder Instability: Shoulder instability, whether acute due to injury or chronic due to loose ligaments, can alter the mechanics of the shoulder joint, making it more prone to impingement. It can create a scenario where normal movements lead to an increased risk of tendon compression against the acromion.

Treatment Options for Shoulder Impingement

Fortunately, most cases of shoulder impingement can be effectively treated through conservative measures, although some may require surgical intervention.

1. Physical Therapy: A tailored physical therapy program is often the first line of treatment. This may include exercises to strengthen the shoulder muscles, improve posture and restore motion. Therapists also use manual therapy techniques to relieve pain and improve function.
2. Activity Modification: Altering or avoiding activities that trigger pain is vital for recovery. Individuals are advised to minimize overhead movements or heavy lifting until the condition improves.
3. Medications: Over-the-counter pain relief medications, like NSAIDs (nonsteroidal anti-inflammatory drugs), can help reduce inflammation and relieve discomfort associated with shoulder impingement.
4. Corticosteroid Injections: In some cases, a doctor may recommend corticosteroid injections to reduce inflammation and alleviate pain, particularly if conservative management doesn’t yield sufficient relief.
5. Surgery: If conservative treatments fail to relieve symptoms over time, surgical options may be considered. Surgery often involves the removal of bone spurs or a portion of the acromion (subacromial decompression) to create more space for the rotator cuff tendons.

Frequently Asked Questions (FAQs)

What are the symptoms of shoulder impingement?

Common symptoms include shoulder pain, particularly during overhead activities, arm weakness and limited range of motion. Pain may also radiate down the arm.

How is shoulder impingement diagnosed?

Diagnosis typically involves a physical examination and a review of symptoms. Imaging tests, like X-rays or MRI, may also be conducted to assess the condition of the rotator cuff and surrounding structures.

Can shoulder impingement happen to anyone?

Yes, shoulder impingement can affect individuals of all ages, but it is more common in those participating in repetitive overhead activities, as well as older adults, due to degenerative changes.

How long does it take to recover from shoulder impingement?

Recovery time can vary. Many individuals start to feel better within a few weeks with physical therapy, but complete recovery can take several months, especially if surgery is involved.

Can I prevent shoulder impingement?

Yes, maintaining good posture, avoiding repetitive overhead motions when possible, and regularly strengthening shoulder-stabilizing muscles can help prevent shoulder impingement.
