Shoulder impingement is a common cause of pain and limited mobility, especially for athletes, manual laborers, and individuals who perform repetitive overhead movements. This condition occurs when the tendons of the rotator cuff become pinched between the bones of the shoulder, leading to inflammation, irritation, and discomfort. Understanding the symptoms, causes, and treatment options can help you seek care early and avoid long-term damage. At the practice of Steven C. Thomas, MD and Donald W Pennington, DO, our board-certified surgeons specialize in orthopedic procedures in the Las Vegas area.
What Is Shoulder Impingement?
The shoulder joint is made up of the humerus (upper arm bone), scapula (shoulder blade), and clavicle (collarbone). The rotator cuff tendons run through a small space between the acromion (part of the scapula) and the humeral head. When this space becomes narrowed, the tendons rub against the bone during movement—this is known as impingement.
Common Symptoms of Shoulder Impingement
-
Pain when lifting the arm overhead or behind the back
-
Discomfort that worsens at night, especially when lying on the affected shoulder
-
Weakness in the shoulder or arm
-
Limited range of motion
-
A “catching” or “grinding” sensation during movement
If left untreated, impingement can lead to more serious conditions like rotator cuff tears or chronic shoulder instability.
Causes and Risk Factors
-
Repetitive overhead activities (throwing, swimming, painting)
-
Poor posture, which alters shoulder mechanics
-
Bone spurs that narrow the shoulder space
-
Previous shoulder injuries
-
Age-related tendon degeneration
Diagnosis
A physician will evaluate your symptoms, review your medical history, and perform a physical exam. Imaging tests like X-rays, MRI, or ultrasound may be ordered to assess tendon health and rule out other issues.
Treatment Options for Shoulder Impingement
Non-Surgical Treatments:
-
Rest and Activity Modification: Avoid overhead activities that trigger pain.
-
Physical Therapy: Strengthening and stretching exercises to improve posture and shoulder mechanics.
-
Anti-Inflammatory Medications: Reduce swelling and pain.
-
Corticosteroid Injections: Provide temporary relief for inflammation.
Surgical Treatments:
If conservative care fails after several months, surgery may be recommended. Arthroscopic subacromial decompression removes bone spurs or reshapes the acromion to relieve tendon pressure.
Preventing Shoulder Impingement
-
Maintain good posture
-
Warm up before physical activity
-
Avoid repetitive overhead lifting without breaks
-
Strengthen rotator cuff and shoulder blade muscles
