A torn rotator cuff can cause neck pain, though this discomfort is typically an indirect or secondary symptom. The rotator cuff is a group of four muscles and tendons that stabilize the upper arm bone within its socket and assist with movement. When a tear occurs, it compromises the shoulder’s stability and strength, forcing other muscles to work harder. This resulting imbalance and strain can translate into pain felt in the neck and upper back.
Understanding the Rotator Cuff and Neck Relationship
The shoulder and neck function together as part of a single, continuous system known as the kinetic chain. This chain includes the cervical spine, the thoracic spine, and the shoulder girdle, meaning dysfunction in one area affects the others. The major nerves that supply the shoulder and arm muscles originate from the cervical spine. Specifically, the C5 and C6 nerve roots emerge from the neck vertebrae and travel directly to the shoulder region.
This shared neurological pathway explains referred pain, where an injury in the shoulder irritates a nerve branch, causing the sensation of pain to be perceived in the neck, and vice versa. Although a torn rotator cuff is a shoulder problem, the entire shoulder complex depends on the neck and upper back for a stable foundation.
The Primary Cause: Compensatory Movement Patterns
The most common reason a torn rotator cuff leads to neck pain is the development of compensatory movement patterns. When the rotator cuff muscles are injured or weakened, they can no longer efficiently stabilize the shoulder joint or initiate arm movement. The body attempts to protect the injured area and maintain the ability to use the arm.
To overcome the shoulder’s weakness, the body recruits accessory muscles for tasks they were not designed to handle. This overuse targets the upper trapezius and levator scapulae muscles, which originate in the neck and attach to the shoulder blade. These muscles are forced to elevate the shoulder blade excessively to help lift the arm, leading to chronic tension and fatigue. This chronic strain and muscle guarding are the direct mechanical drivers of the secondary neck pain.
Differentiating Shoulder Pain from Cervical Pain
Determining the true source of pain is a diagnostic challenge because a neck issue, such as cervical radiculopathy, can present with symptoms identical to a rotator cuff tear. Healthcare providers must perform a physical examination to differentiate the two conditions. Pain that worsens with overhead activities is more typical of shoulder pathology. Conversely, pain relieved when the arm is lifted overhead (the shoulder abduction sign) often indicates a cervical nerve issue.
Specific physical exam maneuvers help isolate the source of discomfort. Specialists may use tests like the Empty Can test to provoke rotator cuff pain or the Spurling’s test to reproduce symptoms originating from the cervical spine. The quality of the pain can offer clues: dull and aching pain is consistent with a shoulder problem, while burning, electric, or shooting pain radiating down the arm suggests a nerve-related issue from the neck. Imaging, such as an MRI, is often used to confirm the location and severity of a rotator cuff tear or to identify pathology in the cervical spine.
Targeted Relief and Treatment Approaches
Successful treatment for neck pain stemming from a rotator cuff tear requires addressing the underlying shoulder injury, not just the neck symptoms. Physical therapy is usually the first non-surgical approach, focusing on restoring the function and strength of the rotator cuff muscles. Strengthening the cuff helps the shoulder regain stability, which reduces the need for the neck muscles to compensate. The therapist also works to correct poor scapular rhythm, ensuring the shoulder blade moves smoothly and efficiently, reducing the chronic load placed on the upper trapezius and levator scapulae.
If the tear is severe and conservative measures fail, surgical repair of the rotator cuff may be necessary to restore full function. When the primary shoulder pathology is resolved, the secondary pain drivers in the neck are eliminated, leading to long-term relief from tension and discomfort. Non-surgical options like steroid injections can provide temporary relief from inflammation and pain, which facilitates the physical therapy process.
