Arthrogryposis Clinic

Arthrogryposis is a set of conditions that can cause a child’s joints to be stiff and not move like they should. This can make it difficult for kids to run, jump and play. At Phoenix Children’s, we want to make it easier for your child to move throughout their day so they can thrive and grow into their greatest potential.

The team within our Arthrogryposis Clinic works with children of all ages to develop a comprehensive and personalized treatment plans that helps to relieve pain and improve range of motion. We’ll also connect you to the resources and support you and your child may need along the way.


What Is Arthrogryposis?

Arthrogryposis—also called arthrogryposis multiplex congenita (AMC)—is a set of conditions characterized by stiffness and loss of motion in more than one joint. This stiffness is caused by shortening and hardening of muscles, tendons or other tissue (contractures).

Arthrogryposis can be mild or severe. Symptoms vary and may include: 

  • Curvature of the spine
  • Difficulty moving the arms and legs
  • Joints that are fixed in one position
  • Weak or missing muscles
  • Webbing or other differences in the skin around the joints

Children are born with the condition or syndrome causing their arthrogryposis. Arthrogryposis is permanent, but symptoms don’t get worse over time and can be treated. In fact, early treatment for arthrogryposis is often very successful at improving or restoring movement to help children live healthy, active lives.

Arthrogryposis can be complex and affect many areas of a child’s life. Families are also greatly impacted.
