Boutonniere Deformity: Causes, Diagnosis and Treatment

Boutonniere deformity is a condition in which the proximal joint (away from the knuckle joint) of the finger goes into flexion and the distal joint goes into extension.

Before reading further it would be good to first see Swan Neck Deformityand Finger Anatomy (skip if you have already done so).

In this deformity the lateral slips that extend the distal joint move downwards (towards the palmer surface) and become stiff.

Now as you try to extend the finger these lateral slips flex the proximal joint (because of there downward position). And their stiffness and tightening causes extension of the distal joint, this produces the deformity.

Common causes include

  • cerebral palsy
  • rheumatoid arthritis

Classification is into three types

  • Mild
  • Moderate
  • Severe

Treatment includes

  • splinting the finger
  • exercises and gentle stretching
  • tendon reconstruction
  • joint fusion
  • joint replacement

Testimonials

My compliments to you and your website. It provides the necessary knowledge and guide to bridge the gap caused by the bits of (mis)information given on most sites. Your website provides a short course on the subject. It not only guides the user, it also provides fundamental knowledge for researching the topic. Giving the user a remarkable and unmatched understanding of their topic. An ounce of knowledge makes for a better patient. I've been longing for a website such as yours. A website that is filled with information a layman can use. Its Not too complicated that it discourages the user.

Thank You for bridging the gap for me and for everyone else.
