  1. Boutonniere Deformity

  2. What is Boutonniere Deformity? • Boutonnière deformity is an injury to the tendons in your fingers that usually prevents the finger from fully straightening. The result is that the middle joint of the injured finger bends down, while the fingertip bends back.

  3. The Anatomy • There are several tendons in your fingers that work together to bend and straighten the finger. These tendons run along the side and top of the finger. The tendon on the top of the finger attaches to the middle bone of the finger (the central slip of tendon). When this tendon is injured, the finger is not able to be fully straightened

  4. Causes • Boutonnière deformity is generally caused by a forceful blow to the bent finger, a cut on the top of the finger, or arthritis.

  5. Non-surgical Treatment • Boutonnière deformity must be treated early to help you retain the full range of motion in the finger. • Splints • Exercises • Protection

  6. Surgical Treatment Options • While nonsurgical treatment of boutonnière deformity is preferred, surgery is an option in certain cases, such as when: • The deformity results from rheumatoid arthritis. • The tendon is severed. • A large bone fragment is displaced from its normal position. • The condition does not improve with splinting. • Surgery can reduce pain and improve functioning, but it may not be able to fully correct the condition and make the finger look normal. If the boutonniere deformity remains untreated for more than 3 weeks, it becomes much more difficult to treat.

  7. Recovery • Recovery from boutonniere deformity surgery can take three to four months. It can take up to six months for a full recovery. Recovery is individualized and your doctor will let you know what to expect.
