(Mild Acute Glenohumeral Ligament Injury)
A shoulder sprain is stretching or partial tearing of the ligaments and capsule that support the shoulder, specifically, the glenohumeral joint. Ligaments are strong bands of tissue that connect bones to each other. The glenohumeral joint is the meeting of the upper arm bone, humerus, and the cup of the shoulder blade.
The major ligaments of the glenohumeral joint are the superior, middle and inferior glenohumeral ligaments, and they serve to stabilize the highly mobile joint. The capsule of the glenohumeral joint is thinner tissue that encloses and supports the shoulder joints.
An acute mild injury to the glenohumeral ligaments can be considered a shoulder sprain. More severe injury can result in dislocation.
Capsule of Glenohumeral Joint
Shoulder sprains involving the glenohumeral joint may be caused by:
- Falling on an outstretched arm
- Forced twisting of the arm
- A blow to the shoulder
A risk factor is something that increases your chance of getting a disease, condition, or injury. Risk factors for shoulder sprain include:
- Playing sports
- Poor coordination
- Poor balance
- Inadequate flexibility and strength in muscles and ligaments
- Loose joints or connective tissue disorders
Symptoms of shoulder sprain may include:
- Pain, tenderness, and swelling around the shoulder
- Redness, warmth, or bruising around the shoulder
- Limited ability to move the shoulder and increased pain with movement
The doctor will ask about your symptoms and how you injured your shoulder. The doctor will examine your shoulder to assess the stability of the joint and the severity of the injury.
Tests may include:
- Rest—Avoid using your injured arm.
- Ice—Apply ice or a cold pack to the shoulder for 15-20 minutes, four times a day for at least 2-3 days. This helps reduce pain and swelling. Wrap the ice or cold pack in a towel. Do not apply the ice directly to your skin.
Medication—First consult your doctor if you have any questions about using medications. OTC drugs that are commonly used to help reduce inflammation and pain include:
- Nonsteroidal anti-inflammatories such as ibuprofen (Motrin, Advil) or naproxen (Aleve, Naprosyn)
- Acetaminophen (Tylenol)
- Brace or sling—You may need to wear a sling to immobilize your arm and shoulder. If you play sports, you may need to wear a shoulder brace when you return to play.
- Rehabilitation exercises—Begin exercises to restore flexibility, range of motion, and strength in your shoulder as recommended by your healthcare professional. Sometimes electrical stimulation is used to aid recovery.
- Surgery—is not always needed to repair a mild shoulder sprain without instability or dysfunction. In certain athletes, earlier surgery may be considered to avoid recurrent injury.
