Can people with arthrogryposis multiplex congenita survive long?

Depends: The severity of the problem varies. Most folks with it have normal lifespans, but if there is severe thoracic scoliosis restricting lung function, life expectancy could be reduced.

Depends: It depends on the severity of the problem (it varies widely). For example, some have severe scoliosis, limiting chest movement and lung inflation. Some have small lungs. These could reduce lifespan. On the other hand, many with amc have normal life expectancy.
