[Arthrogryposis Multiplex Congenita in pediatric age: Correlation between Muscle MRI and functional assessment].

Arthrogryposis multiplex congenita (AMC) is a group of diseases with joint limitations at two or more distinct joint levels at birth. Joint limitations are not progressive, but the functional consequences have a lifelong impact on patients. In this article we will present the results of our study aimed at evaluating the correlation between muscle fat infiltration on MRI and activity deficiencies and limitations in children with AMC. Our study is one of the first in a pediatric population to establish the link between muscle imaging and functional aspects of AMC.
