Disease at a Glance

Madelung deformity (MD) is a rare congenital (present from birth) condition in which the wrist grows abnormally and part of the radius, one of the bones of the forearms, stops growing early and is short and bowed. The other forearm bone, the ulna, keeps growing and can dislocate, forming a bump. It is more commonly observed in females. Symptoms include a decreased range of motion in the wrist, pain, and a visible difference in the appearance of the wrist. In addition to the abnormal growth, there is also an abnormal palmar (Vickers' ligament) that is thought to contribute to the deformity. MD seems to be caused by a combination of both genetic and acquired factors (such as following a trauma or overuse of the joint). MD can also occur as part of another conditions. Leri Weill dyschondrosteosis, characterized by bilateral Madelung deformity and short stature with short arms and legs, is caused by genetic changes or losses of genetic material involving the SHOX gene. Some cases of isolated MD may be caused by alterations in the SHOX gene.

Next Steps

Talking with the Medical Team

Good communication between the patient, family, and medical team can lead to an accurate diagnosis. In addition, health care decisions can be made together which improves the patient’s well-being and quality of life.

Describing Symptoms

Describe details about the symptoms. Because there may be many different causes for a single symptom, it is best not to make a conclusion about the diagnosis. The detailed descriptions help the medical provider determine the correct diagnosis.

To help describe a symptom:

  • Use a smartphone or a notebook to record each symptom before the appointment
  • Describe each symptom by answering the following questions:
    • When did the symptom start?
    • How often does it happen?
    • Does anything make it better or worse?
  • Tell the medical team whether any symptoms affect daily activities

Preparing for the First Visit

Working with a medical team to find a diagnosis can be a long process that will require more than one appointment. Make better health decisions by being prepared for the first visit with each member of the medical team.

    Make informed decisions about health care: 
    • Prepare a list of questions and concerns before the appointment
    • List the most important questions first, not all questions may be answered in the first visit
    • Ask questions about symptoms, possible diagnoses, tests, and treatment options
    For future appointments:
    • Discuss what was not addressed at the last visit
    • Discuss changes in the quality of life for the patient, family, and caregivers
    • Discuss health goals and other issues in the patient’s and family’s life that may affect the health care decisions
    Take notes during the appointments to help remember what was discussed.
