What is camptodactyly?

Camptodactyly means that your child has a bent finger that they cannot completely straighten. The finger typically bends in the middle of the finger, at a joint called the proximal interphalangeal (PIP) joint.

A pinkie finger with camptodactyly that bends abnormally at the proximal interphalangeal PIP joint.

For some children, a finger can be straightened with help from another person (passive motion). For others, the joint may be so tight that it can’t be straightened, even with help.

Camptodactyly affects about 1 percent of children to some degree. It affects girls more than boys.

What are the different types of camptodactyly?

Type I: Infantile camptodactyly

  • affects boys and girls equally
  • responds well to stretching and splinting

Type II: Adolescent camptodactyly

  • affects girls more frequently than boys
  • may require surgical treatment

Type III: Syndromic camptodactyly

  • affects multiple fingers
  • associated with various syndromes
  • often severe and present at birth

Camptodactyly | Symptoms & Causes

What are the symptoms of camptodactyly?

If your child has a mild case of camptodactyly, they may not have any symptoms. Their finger (probably the little one) will be slightly curved, but it won’t affect their use of their hand. If your child has a more severe case, it could slightly affect their hand function.

What causes camptodactyly?

Camptodactyly can be caused by abnormal structures in your child’s finger. These may include:

  • tight skin
  • contracted tendons and ligaments
  • abnormal muscles
  • irregularly shaped bones

Most of the time, there is no known reason why this happens. But some children with camptodactyly have a family history of similar finger problems.

Camptodactyly also can also be part of a larger condition or syndrome that affects many different parts of the body.

Camptodactyly | Diagnosis & Treatments

How is camptodactyly diagnosed?

To diagnose camptodactyly, your child’s doctor will go over your child’s full medical history and do a careful physical examination. Your child may have an x-ray to confirm the diagnosis.

How is camptodactyly treated?

Mild camptodactyly rarely causes pain or problems with function, so surgery is not usually recommended. If your child’s condition is mild, your child’s doctor will probably recommend that they wear a splint and receive occupational therapy.

Your child may need surgery if the curve in their finger is more serious, especially if it is getting worse. While surgery can help improve function, your child may still have some curve in their finger. Splinting and occupational therapy are necessary after surgery to prevent stiffness.
