Boutonniere deformity

Boutonniere deformity is a medical condition that affects the fingers, causing them to bend or flex in an abnormal way. This condition is often caused by injury or diseases such as rheumatoid arthritis or osteoarthritis.

Causes

The primary cause of Boutonniere deformity is an injury to the tendons that straighten the finger's middle joint. These tendons can be damaged during sports or other physical activities. Diseases such as rheumatoid arthritis can also cause this deformity.

Symptoms

The main symptom of Boutonniere deformity is the abnormal bending or flexing of the finger. This can make it difficult to straighten the finger or use it normally. Other symptoms may include pain, swelling, and stiffness in the affected finger.

Diagnosis

Boutonniere deformity is usually diagnosed through a physical examination. The doctor may also order imaging tests such as X-rays to confirm the diagnosis and assess the severity of the deformity.

Treatment

Treatment for Boutonniere deformity typically involves physical therapy and splinting to help straighten the finger. In severe cases, surgery may be required to repair the damaged tendons.

Prevention

Preventing Boutonniere deformity involves avoiding injuries to the fingers. This can be achieved by using protective equipment during sports and other physical activities, and by managing chronic diseases such as rheumatoid arthritis effectively.
