Causes of Boutonnière Deformity 

Boutonnière deformity is a condition that affects the finger and can lead to a significant impact on joint function. This deformity occurs when there is damage or injury to the flexor and extensor tendons of the finger. Understanding the causes of boutonnière deformity is crucial in diagnosing and treating this complex finger injury. 

Injuries to the Flexor Tendons 

The flexor tendons are responsible for bending the fingers. When these tendons are injured, it can result in a boutonnière deformity. This injury often occurs when there is a forceful impact to the finger, such as during a sports related accident or when a finger gets caught in a door. The damage to the flexor tendons affects their ability to function properly, leading to the characteristic deformity. 

Injuries to the Extensor Tendons 

The extensor tendons, on the other hand, are responsible for straightening the fingers. When these tendons are injured, it can also contribute to the development of boutonnière deformity. This type of injury often occurs when there is a severe cut or laceration on the back of the finger, damaging the extensor tendons. Without proper treatment, the extensor tendons may not heal correctly, resulting in the deformity. 

Other Causes 

In addition to tendon injuries, other factors can contribute to the development of boutonnière deformity. These include: 

Arthritis: Inflammatory conditions like rheumatoid arthritis can weaken the tendons and joints, making them more susceptible to deformities. 

Inherited conditions: Certain genetic disorders can affect the structure and function of the fingers, increasing the risk of boutonnière deformity. 

Repetitive stress: Activities that involve repetitive finger movements, such as typing or playing musical instruments, can put strain on the tendons and increase the risk of deformity over time. Understanding Boutonnière Deformity of Finger
