What Is Arthrogryposis?


Arthrogryposis, a rare congenital condition, affects individuals from birth and is characterised by multiple joint contractures. This condition can impact mobility and range of motion, presenting unique challenges for those living with it. In this blog post, we will delve into the causes, symptoms, and available treatments for arthrogryposis.

What is Arthrogryposis?

Arthrogryposis, also known as arthrogryposis multiplex congenita (AMC), is a term that encompasses a group of conditions involving limited joint movement and muscle weakness at birth.It occurs due to fetal joint contractures, which prevent normal joint development and movement in utero. The term “arthrogryposis” is derived from the Greek words meaning “curved joint.”

What causes Arthrogryposis?

The exact cause of arthrogryposis is not always clear, but it is believed to result from a combination of genetic and environmental factors. Various genetic mutations and prenatal factors can contribute to the development of joint contractures in the foetus. Conditions such as muscle disorders, nerve damage, maternal illness, or decreased fetal movement can all play a role in arthrogryposis.

Arthrogryposis diagnosis

Diagnosis can be made prenatally in approximately 50% of foetuses with arthrogryposis. Routine ultrasounds can display a lack of mobility and abnormal positions of the foetus. A child can be diagnosed with arthrogryposis via physical examination, confirmed by ultrasound, MRI, or muscle biopsy.

Arthrogryposis prognosis

Arthrogryposis is non-progressive, so with proper medical treatment, health can be stable or improved. Arthrogryposis cannot be cured, but with appropriate treatment, most children significantly improve their range of motion and ability to move their limbs, enabling full lives. Surgical intervention may also improve joint mobility and function.

Arthrogryposis treatment

Arthrogryposis treatment includes occupational therapy, physical therapy, splinting, and surgery. These treatments aim to increase joint mobility and muscle strength and the development of adaptive use patterns that allow for walking and independence with activities of daily living. Since arthrogryposis includes many different types, the treatment varies between patients depending on the symptoms. Surgical techniques may also be used.
