Isolated sternocostoclavicular hyperostosis (ISCH) is a rare condition characterized by the abnormal growth of bone around the sternoclavicular joint, which is the joint between the sternum and the clavicle. Symptoms of ISCH include pain and swelling in the area of the sternoclavicular joint, as well as limited range of motion in the shoulder and neck. Treatment typically involves physical therapy and anti-inflammatory medications. In some cases, surgery may be necessary to remove the excess bone growth.

The most common symptom of Isolated Sternocostoclavicular Hyperostosis (ISCH) is Pain and tenderness in the sternoclavicular joint, which is located at the top of the chest where the collarbone meets the sternum. Other symptoms may include swelling, stiffness, and limited range of motion in the affected joint. In some cases, the Pain may radiate to the neck, shoulder, and arm.

The exact cause of isolated sternocostoclavicular hyperostosis is unknown. However, some potential causes may include:

• Genetic predisposition
• Trauma or injury to the area
• Inflammatory conditions such as rheumatoid arthritis
• Infections such as tuberculosis
• Metabolic disorders such as hyperparathyroidism
• Endocrine disorders such as hypothyroidism
• Certain medications such as steroids

1. Non-surgical treatments:

- Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and pain
- Physical therapy to improve range of motion and strength
- Heat and cold therapy to reduce pain and inflammation
- Corticosteroid injections to reduce inflammation

2. Surgical treatments:

- Arthroscopic surgery to remove the excess bone growth
- Open surgery to remove the excess bone growth and repair any damage to the joint
- Joint fusion to stabilize the joint and reduce pain

1. Male gender
2. Age (usually between 20-50 years old)
3. Obesity
4. Smoking
5. Genetic predisposition
6. Certain medications (such as corticosteroids)
7. Trauma or injury to the chest or shoulder area
8. Certain medical conditions (such as ankylosing spondylitis, psoriatic arthritis, and inflammatory bowel disease)

There is no known cure for isolated sternocostoclavicular hyperostosis. Treatment typically involves medications to reduce inflammation and pain, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids. Physical therapy may also be recommended to help improve range of motion and reduce pain. Surgery may be recommended in severe cases.
