What is Boutonnière Deformity? 

Boutonnière deformity is a finger condition characterized by the abnormal appearance and function of the middle joint, known as the proximal interphalangeal (PIP) joint. It occurs when the tendon that straightens the PIP joint (the extensor tendon) is damaged or weakened, leading to its inability to fully extend the finger. This results in a permanent flexed position at the PIP joint, while the end joint (distal interphalangeal joint) remains extended. 

People affected by boutonnière deformity may notice a variety of symptoms, including: 

Pain and tenderness at the PIP joint 

Difficulty straightening the finger 

Visible deformity and misalignment of the finger 

Reduced range of motion 

This deformity can significantly impact daily activities, making it challenging to grasp or manipulate objects with the affected finger. It is important to address boutonnière deformity promptly to prevent further complications and promote optimal hand function. 

Causes of Boutonnière Deformity 

Boutonnière deformity can be caused by various factors, including trauma, arthritis, and autoimmune conditions. Understanding these causes is essential for effective treatment and prevention. 

1. Trauma: Injuries to the finger, such as forceful impact or a deep cut, can damage the extensor tendon, leading to boutonnière deformity. The extensor tendon is responsible for straightening the finger, and when it is injured, the balance of the finger’s movement is disrupted. 
2. Arthritis: Arthritis, particularly rheumatoid arthritis, can contribute to the development of boutonnière deformity. In this condition, chronic inflammation affects the finger joints, causing them to become stiff and deformed. Over time, the inflammation can lead to weakening of the tendons, resulting in the characteristic bent finger position. 
3. Autoimmune Conditions: Certain autoimmune conditions, such as systemic lupus erythematosus and psoriatic arthritis, can also increase the risk of boutonnière deformity. These conditions cause the immune system to mistakenly attack healthy tissues, including the finger joints and tendons, leading to joint damage and deformity.

It is important to note that the specific causes of boutonnière deformity may vary from person to person. Some individuals may develop the condition due to a combination of factors, while others may have a single primary cause. Understanding Boutonnière Deformity Causes & Care 

Cause Description 

Trauma Injuries to the finger, such as forceful impact or deep cuts, that damage the extensor tendon. Arthritis Chronic inflammation of the finger joints, particularly in cases of rheumatoid arthritis, which can weaken the tendons. 

Autoimmune Conditions 

Specific autoimmune diseases, such as systemic lupus erythematosus and psoriatic arthritis, that cause the immune system to attack healthy finger tissues. 

Treatment Options for Boutonnière Deformity 

When it comes to treating boutonnière deformity, there are several options available depending on the severity of the condition and the individual’s specific needs. These treatment options aim to restore finger function, alleviate pain, and improve overall hand mobility. 

Splinting 

One of the non-surgical treatment approaches for boutonnière deformity is splinting. A splint is a device that helps to immobilize the affected finger and keep it in the correct position, allowing the damaged extensor tendon to heal properly. Splinting is often recommended during the initial stages of boutonnière deformity or for mild cases. 

Splints for boutonnière deformity are typically made of lightweight materials that can be easily worn and adjusted. The splint is designed to keep the middle joint of the finger extended, while allowing movement at the other joints. By maintaining the correct alignment of the finger, the splint helps prevent further deformity and promotes healing. 

In some cases, the splint may need to be worn continuously for several weeks, while in others, it may only be required during certain activities or at night. The duration and specific instructions for splinting will be determined by a healthcare professional based on the individual’s condition. 

Exercises 

In addition to splinting, certain exercises and stretches can also be beneficial in treating boutonnière deformity. These exercises aim to improve finger flexibility, strengthen the surrounding muscles, and restore normal hand function. 

It is important to note that exercises for boutonnière deformity should be performed under the guidance of a healthcare professional or a certified hand therapist. They will provide instructions on the appropriate exercises, their frequency, and the recommended intensity. 

Some common exercises for boutonnière deformity may include: 

1. Passive and active finger extension exercises 
2. Joint mobilization exercises 
3. Grip and pinch strengthening exercises 
4. Range of motion exercises 

These exercises should be performed consistently and may be complemented with other therapeutic modalities, such as heat therapy, ultrasound, or electrical stimulation, to enhance the treatment outcomes. 

Surgery

In severe or persistent cases of boutonnière deformity, surgery may be recommended. Surgical treatment aims to correct the anatomical abnormalities and restore normal finger function. 

During the surgery, the damaged extensor tendon is repaired, and any joint deformities are addressed. The specific surgical techniques and procedures will depend on the individual case and the surgeon’s expertise. Understanding Boutonnière Deformity Causes & Care 

Post-surgery, a comprehensive rehabilitation program will be prescribed, including exercises, splinting, and regular follow-up appointments. The recovery period may vary, but with proper care and adherence to the rehabilitation plan, most individuals can expect significant improvement in finger function and appearance. 

It is important to consult with a qualified healthcare professional to determine the most suitable treatment approach for boutonnière deformity. They will assess the severity of the condition and consider factors such as the individual’s overall health, lifestyle, and treatment goals to develop a personalized treatment plan. 

Splinting for Boutonnière Deformity 

When it comes to treating boutonnière deformity, splinting is a non-surgical option that can be highly effective. A splint is a device worn on the affected finger to help correct the deformity and maintain proper alignment during the healing process. 

How does splinting work? 

A splint works by immobilizing the finger in a straight position, preventing further bending of the middle joint (known as the PIP joint) and allowing the extensor tendon to heal properly. By providing support and stability, splinting helps to gradually restore the finger’s normal functionality. 

Effectiveness of splinting: 

Splinting is most effective when started as early as possible after the onset of boutonnière deformity. It is crucial to consult with a healthcare professional to determine the appropriate splinting technique and duration, as well as to monitor the progress. 

A study conducted by Smith et al. found that splinting alone was successful in correcting boutonnière deformity in 80% of the cases. The study also highlighted the importance of compliance, emphasizing the need for consistent splint wear and adherence to the recommended treatment plan. 

Types of splints: 

There are various types of splints available for boutonnière deformity. The selection depends on factors such as the severity of the deformity and the patient’s individual needs. Some commonly used splints include: 

1. Plastic finger splints: These are lightweight, durable, and adjustable, providing customized support to the affected finger. 
2. Stack splints: These are designed to correct both boutonnière deformity and mallet finger, which often occur together. 
3. Dynamic splints: These splints use an adjustable spring system to provide controlled dynamic force, facilitating finger extension. 

Advantages of splinting: 

Non-invasive: Splinting offers a non-surgical alternative to managing boutonnière deformity. Cost-effective: Splints are generally more affordable compared to surgical interventions. Conservative approach: Splinting allows for conservative treatment that prioritizes preserving natural finger structures and function. 

Flexibility: Splints can be removed and repositioned for gentle exercises and stretching, helping to gradually strengthen the finger. 

If splinting alone does not produce the desired results or if the deformity is severe, surgical intervention may be necessary. However, splinting is often the first line of treatment for boutonnière deformity due to its effectiveness and non-invasive nature. 

Boutonnière Deformity Exercises 

If you have been diagnosed with boutonnière deformity, incorporating specific exercises and stretches into your daily routine can help improve finger flexibility and function. These exercises focus on strengthening the muscles and tendons in the finger, promoting proper alignment and preventing further progression of the deformity. Understanding Boutonnière Deformity Causes & Care 

Here are some recommended boutonnière deformity exercises: 

1. Finger Extension Stretch: Start by placing your affected finger on a flat surface with the palm facing down. Gently press down on the finger, extending it as straight as possible. Hold this stretch for 10-15 seconds, then release. Repeat this exercise 5-10 times, gradually increasing the duration and repetitions as tolerated. 
2. Rubber Band Resistance Exercise: Loop a rubber band around your affected finger and gently open your hand, stretching the rubber band. This exercise helps strengthen the extensor tendons and improve finger extension. Perform 10-15 repetitions, gradually increasing the resistance of the rubber band over time. 
3. Thumb Opposition Exercise: Place your affected thumb on the tip of each finger, starting with the index finger and moving towards the little finger. Try to touch the thumb to the fingertip and hold for a few seconds before releasing. Repeat this exercise with each finger, promoting finger dexterity and flexibility. 
4. Finger Flexor Strengthening: Use a soft ball or putty to squeeze and strengthen the finger flexor muscles. Hold the squeeze for a few seconds before releasing. Repeat this exercise 10-15 times, gradually increasing the resistance of the ball or putty. 
5. Range of Motion Exercises: Perform gentle finger bends and extensions, moving the affected finger through its full range of motion. Start with slow, controlled movements and gradually increase the speed and intensity as tolerated. Repeat these exercises 10-15 times. 

Remember to perform these exercises under the guidance of a healthcare professional or a certified hand therapist. They can provide you with personalized instructions and modifications based on your specific condition and recovery progress. 

Surgical Treatment for Boutonnière Deformity 

For severe or persistent cases of boutonnière deformity, surgical intervention may be recommended. Boutonnière deformity surgery aims to correct the underlying structural issues in the finger to restore proper alignment and function. 

The specific surgical procedure will depend on the individual patient’s condition and the severity of the deformity. Some common surgical options for boutonnière deformity include: 

1. Tenosynovectomy: This procedure involves removing the inflamed synovial tissue, which can improve finger mobility and reduce pain. 
2. Tendon repair: If the central slip or other tendons in the finger are damaged, surgery may be performed to repair or reconstruct them. 
3. Joint arthroplasty: In cases where the joint is severely damaged, joint replacement surgery may be necessary to restore finger function. 

During surgery, a local or general anesthetic may be used to ensure the patient’s comfort. The surgeon will make incisions to access the affected structures and carefully repair or reconstruct them. After the procedure, the incisions will be closed, and the hand may be immobilized with a splint or cast to aid in the healing process. 

As with any surgical procedure, boutonnière deformity surgery carries some risks. These may include infection, nerve damage, stiffness, or the need for additional surgeries. However, for many patients, surgery can provide significant relief from pain and improve finger function. Understanding Boutonnière Deformity Causes & Care
