What type of disorder is arthrogryposis?

Arthrogryposis is categorized as a non-progressive congenital disorder characterized by joint contractures and muscle weakness at birth. This condition arises from various factors that affect fetal development, leading to a decrease in normal movement and resulting in fixation of the joints in characteristic positions.

In the context of arthrogryposis, the term "non-progressive" is crucial; it indicates that while the individual may face limitations due to the joint contractures, the underlying condition does not worsen over time. This differentiates it from disorders that involve progressive deterioration, such as certain neurological or degenerative disorders.

Understanding that arthrogryposis is congenital reinforces the idea that it originates before birth and is not a result of later-life factors or diseases. The congenital aspect emphasizes the importance of early diagnosis and intervention to maximize mobility and function, as these can significantly help individuals adapt to their specific muscle and joint limitations.
