The deformation of the finger type "boutonniere" – Tendon rupture extensor muscles

Description deformation finger buttonhole

Finger buton′erkoj deformation occurs due to damage to the tendons of the fingers. The tendons allow you to flex and straighten the finger. In the presence of the deformation finger it is impossible to straighten.

Causes of deformation finger buttonhole

When buttonhole deformation finger tendon on the top of a finger torn or stretched. This creates a gap, that resembles a buttonhole (or boutonniere French). Joint finger bends back. Tendon on top of the finger are flat and thin. They are very prone to injury. If deformed thumb, it affects the metacarpophalangeal joints.

The deformation of the finger can be caused buttonhole:

• Powerful blow to the bent finger;
• Cuts central phalanx;
• Damage to the joints of the finger (so-called proximal interphalangeal joints);
• Severe burn on the hand.

Risk factors

Factors, increases the likelihood of deformation finger buttonhole:

• The presence of rheumatoid arthritis or Dupuytren's contracture;
• Participation in sports, especially those, which include ball throws his hands (handball, basketball).

Symptoms deformation finger buttonhole

These symptoms may be caused by other diseases. You should inform your doctor if any of them:

• Pain and swelling in the upper part of the middle finger joints;
• Inability to straighten finger at the middle joint in the ultimately leads to deformation;
• Signs of injury (eg, fracture or dislocation) middle finger joints;
• Signs of injury (eg, fracture or dislocation) metacarpophalangeal joint.

Diagnosis deformation finger buttonhole

The doctor asks about the symptoms and medical history. He will also perform a physical exam, paying particular attention to:

• Muscle strength;
• Damage to the joints;
• Range of motion;
• The presence of edema;
• Infection of the joint;
• Tactility.

X-rays can be done, to see, whether there is a finger fracture.

Treatment deformation finger buttonhole

Treatment options include the following:

Medication

Your doctor may recommend the following products:

• Corticosteroids, to reduce inflammation;
• Nonsteroidal anti-inflammatory drugs (NSAIDs) – to reduce pain and inflammation.

Non-surgical treatments

In mild cases, treatment nonsurgically may include:

• Splintage:
  • Imposition of tires on the joint, to straighten it;
  • Used for 3-6 weeks;
• Stretching and strengthening joint;
• Other methods: massage, ultrasound therapy, electrostimulation.

If the state of the finger does not improve, perhaps, It needs surgery.

Operation

The operation is needed in severe cases. It can be performed, kogda tendon plowed, or when the deformation is continued for a long time. Typically, the operation does not restore the state to a finger injury. But, perhaps, there will be some improvement. After surgery, you need to do exercises to strengthen the finger.

Prevention deformation finger buttonhole

To reduce the likelihood of deformation finger buttonhole, you need to take the following steps:

• Wear the proper equipment when playing sports;
• In the presence of rheumatoid arthritis, doctor will advise, how to protect joints.
