What is Arthrogryposis Multiplex Congenita (commonly called AMC)?
Arthrogryposis Multiplex Congenita is a condition that causes many joints to be stiff and crooked at birth. A newborn with Arthrogryposis lacks the normal range of motion in one or more joints. A joint that lacks normal range of motion is called a joint contracture. These joint contractures develop before birth (prenatally) and are evident at birth (congenitally). Arthro means joint, Gryposis means crooked, multiplex means multiple and congenita means existing at birth or present at birth. Arthrogryposis Multiplex Congenita is an umbrella and descriptive diagnosis. This means Arthrogryposis can be caused by an underlying condition or syndrome. This underlying condition is usually the type of Arthrogryposis.
