Arthrogryposis

What are the signs of arthrogryposis during pregnancy?

During pregnancy, decreased fetal movement can be a sign of arthrogryposis. If joints and muscles aren’t developing properly, the baby won’t be able to move around in the uterus as much as typical.

What tests are used to diagnose arthrogryposis during pregnancy?

Your obstetrician may recognize signs of arthrogryposis during a routine ultrasound. If they suspect the baby has joint contractures, you may need a more detailed fetal ultrasound to closely examine the extremities and look at the position of the joints.

Some babies with arthrogryposis develop extra fluid in the skin (a condition called cystic hygroma). You may also have excess amniotic fluid surrounding the baby in your uterus (a condition called polyhydramnios). Fetal ultrasound can detect these complications.

What can I expect after a diagnosis of arthrogryposis during pregnancy?

If your baby is diagnosed with arthrogryposis, the experts at our Colorado Fetal Care Center will monitor your pregnancy more closely. You may need additional testing to rule out other possible medical conditions — such as muscular dystrophy and myasthenia gravis.

How is arthrogryposis diagnosed in children? 

In some cases, arthrogryposis isn’t spotted during pregnancy. But your baby’s doctor can usually diagnose it during an early physical exam. In order to make the most accurate diagnosis, your doctor may also order tests such as:

• X-rays
• Ultrasound
• MRI (to see if any organs in the body are affected)
• CT scan
• Biopsy (small tissue sample) of a muscle to see if the muscle fibers are normal
• Blood tests to look for any gene variations or atypical chromosomes that may indicate another disease

How is arthrogryposis treated during pregnancy?

Other than closely monitoring your pregnancy and your baby’s development, there is no treatment for arthrogryposis during pregnancy.  

How is arthrogryposis treated in babies and children?

Your baby will have a thorough physical examination at birth to see which limbs are affected. We’ll also check to see if the condition is affecting their central nervous system or any internal organs. We’ll test the range of motion in their joints, examine the joints’ positions and look for any fractures.

Treatment depends on how many joints are affected and how severely. During the newborn period, we may use casts or splints to help reset joints. Physical therapy and gentle stretching can also help babies improve muscle strength and range of motion.

Hand therapy is an important part of treatment for children with arthrogryposis. Our pediatric hand therapy program includes experts highly trained in this specialty. We typically start hand therapy soon after your baby is diagnosed.

If therapy alone is not enough, your child may need surgery. We perform surgery to improve how your child’s joints move and work. Our pediatric orthopedic surgeons typically are involved early in a child’s care, as surgery may help improve a child’s function.

What is the outlook for children born with arthrogryposis?

Arthrogryposis is non-progressive, which means it doesn’t get worse over time. Most people with arthrogryposis live long, healthy lives.

With treatment, most children improve their range of motion and ability to move their arms and legs. This means they are better able to enjoy activities of daily life.
