Boutonniere Deformity: Symptoms, Causes, and Treatment

Boutonniere deformity is a condition that affects the fingers, causing them to become bent and deformed. It occurs when the tendons that control the movement of the fingers become damaged or torn. This can happen due to a variety of reasons, including injury, arthritis, and genetics.

  1. Symptoms: The primary symptom of boutonniere deformity is the bending of the middle joint of the finger, while the tip and the base remain straight. This creates a "buttonhole" or "boutonniere" appearance. Other symptoms may include pain, swelling, and stiffness in the affected finger.
  2. Causes: Boutonniere deformity can be caused by a variety of factors, including:
    • Trauma or injury to the finger
    • Rheumatoid arthritis
    • Osteoarthritis
    • Genetic factors
    • Repetitive motion activities
  3. Treatment: Treatment for boutonniere deformity depends on the severity of the condition. In mild cases, splinting and exercise may help to improve the condition. In more severe cases, surgery may be necessary to repair or replace the damaged tendons. Other treatment options may include physical therapy, medication, or joint injections.

If you are experiencing symptoms of boutonniere deformity, it is important to seek medical attention. Early diagnosis and treatment can help to prevent the condition from worsening and improve the overall function of your fingers.

In conclusion, boutonniere deformity is a condition that affects the fingers and can cause significant discomfort and functional impairment. Understanding the symptoms, causes, and treatment options can help individuals with this condition to receive appropriate care and improve their quality of life.
