Upon examination, a patient shows symptoms of anterior shoulder pain. What might be a contributing factor?

The presence of anterior shoulder pain can often be attributed to several conditions that affect the structures around the shoulder joint. Subacromial impingement can lead to anterior shoulder discomfort because as the arm is lifted, the rotator cuff tendons may become compressed under the acromion, causing pain in the anterior region of the shoulder. This is particularly prevalent during activities that require overhead motions.

Additionally, a rotator cuff tear can also contribute to anterior shoulder pain. This condition often presents with pain, weakness, and limited range of motion, and may manifest as discomfort felt at the front of the shoulder, especially during movements that engage the affected rotator cuff muscles.

Given that both subacromial impingement and a rotator cuff tear can lead to the same symptom of anterior shoulder pain, it is accurate to conclude that both conditions can significantly contribute to the patient's presentation. Therefore, considering that the symptoms can arise from either one or both conditions, selecting the response that acknowledges both is the most comprehensive and correct choice.
