What does the term arthrogryposis refer to?

Arthrogryposis refers to congenital joint contractures that affect two or more areas of the body. This condition is characterized by decreased flexibility and the ability to move joints, often presenting with rigid limbs due to the presence of multiple joint contractures at birth. It can result from various underlying causes, including abnormalities in the development of the muscles or nerves during fetal growth.

The focus on the presence of multiple joint contractures is essential, as arthrogryposis is not limited to a single joint or limb. This distinction makes it important for diagnosis and potential treatment strategies. Understanding that arthrogryposis signifies a broader impact helps to differentiate it from other conditions that may affect only one area or involve different underlying issues such as muscle weakness or nerve dysfunction.
