Stiff joints since birth

What exactly is AMC?

Definition and cause

Arthrogryphosis multiplex congenita, or AMC for short, is a condition characterized by multiple congenital joint contractures that lead to varying levels of immobility in the spine and extremities.

AMC is not curable. However, it is not progressive. Nevertheless, as the child grows, the contractures can lead to a variety of deformities and functional limitations in movement.

AMC occurs in about one out of 3,000-5,000 live births. The exact cause of AMC is unknown but impaired muscle development in utero and lack of fetal movement appear to be the leading causes. In some cases, AMC is inherited however most incidences occur without a predisposing genetic link.

The symptoms of AMC are variable and often complex. Furthermore, the extent of contractures and joint malalignments caused by AMC can vary significantly. In most cases, the joints in both the arms and legs are affected. However, in a small proportion of cases, only the arms or only the legs are affected. The contractures caused by AMC result in stiff joints. The degree of stiffness will differ from patient to patient.

Contractures can also occur in the wrist, fingers, and ankles which can lead to significant restrictions in movement. One common feature of AMC is pronounced flexion contractures in the wrists, finger joints, and thumb. Scoliosis of the spine may also occur.

AMC may also cause organ and nervous system malformations which could possibly lead to paralysis.

Treatment with orthoses

Constant loads on poorly aligned joints can lead to premature joint wear and tear and cause long term damage. As such, any malalignments should be treated as early as possible. In addition to surgical interventions, many joint malalignments can also be corrected with orthoses. Joint mobility can often be improved through therapy that is targeted at early mobilization and accompanied by dynamic orthotic care. The time at which the treatment is started is critical for successful conservative therapy – therapeutic measures should already be underway during the first few months of life.

In babies, orthotic care should begin around the age of three or four months. Radiological findings and close collaboration with the attending physicians and therapists are essential to providing optimal orthotic care that is individualized to each patient.

Due to the complex characteristics of AMC, orthoses are individually designed and manufactured to fit the patient’s needs.

All-round care!

We have the solution

AMC often causes stiffness in the wrist, finger, and thumb joints. In addition, some patients may experience stiffening of the ankle, knee, and hip joints all of which can restrict movement. These misaligned joints can be corrected with orthoses.

Our orthopedic devices are important components of the medical and therapeutic treatment concept. Amazing results for AMC patients can be achieved in combination with physiotherapy and rehabilitation aids.

Aschau Children’s Clinic

The Orthopedic Children’s Clinic in Aschau is one of the largest specialist clinics for pediatric orthopedics in Central Europe.

Interdisciplinary treatment approach

When it comes to orthopedic treatment for infants and children, it is extremely important for all parties to pull together: parents, doctors, technicians and therapists.

Celine shows them all

Sports with AMC?
– No problem!

AMC: this is what Celine has been suffering from since birth. Despite her congenital joint stiffness, Celine wants to try out everything she feels like doing. She is currently applying for an apprenticeship as an industrial management assistant. She spends her free time with her best friend Marla. Chilling by the lake, eating ice cream... activities that people do when they have some spare time. Her disability hardly plays a role in her daily activities...

Robin has AMC – and a loyal helper

What a great team! Robin (8) has AMC, leaving his movement severely restricted. For more than a year, he has been training with the Labrador retriever, Chester, who reliably helps Robin get on better with everyday life.
