Symptoms And Treatments For Boutonnière Deformity

Boutonnière Deformity is a medical condition that affects the finger. It is due to an injury to the tendons in the finger that is responsible for the flexing and straightening. If this injury is left untreated, it may result in serious complications and the possibility of permanent deformity.

There are a few tendons in our fingers working hand in hand to help us perform flexion and extension. These tendons are located at the side and top of the finger. Boutonnière Deformity affects the tendon that is attached to the middle bone. When other tendons are injured, you will feel pain but bending can still be performed. However in this case, bending and flexing cannot be performed completely.

Symptoms

Symptoms are usually quite straightforward. Patients will feel pain around the finger region and swelling will be present. The finger will not be able to straighten fully on its own but it is able to with external help. However, this forced straightening action will result in an imbalance, causing the finger to arch upwards.

Treatment

Non-surgical

Non-surgical treatment is intended for cases whereby the injury was caused by a simple tear of the tendon. This kind of injury is not very serious and splinting is usually sufficient and the bone will heal on its own. The patient will be required to perform intensive physical therapy throughout the period to prevent stiffness in the finger joint. The choice of finger splint can be divided into the homemade type or the special types that can be bought from hospitals. Non-surgical treatment is also the preferred treatment method that most surgeons will consider prior to suggesting surgery. This is due to the need for the contracture to be stretched further before the extensor hood can be repaired through surgical means.

Surgical

Surgical will be required for cases that are much more serious. Surgery can only take place when the finger joint is in an extended position instead of the arc position and this is why non-surgical treatments will be prescribed initially to allow the finger to extend fully.

Joint fixation

If the injury was caused due to a dislocation of the joint, a joint fixation surgery will need to be carried out. A metallic pin will be used to fix the joint in place. Following surgery, a finger splint will need to be worn in order to protect the joint.

Fusion

Fusion will be the best treatment possible when previous treatment methods fail to fully heal it. Fusion is a procedure that joins 2 of the joint surfaces of the finger together, preventing them from moving. This will help to reduce pain and provide stability to the finger joint.
