Madelung's deformity

Madelung's deformity is a rare congenital condition that affects the bones of the wrist. It is characterized by an abnormality in the growth of the radius, one of the two long bones in the forearm, leading to a deformity of the wrist and forearm. The condition is named after Otto Wilhelm Madelung, a German surgeon who first described it in 1878.

Signs and Symptoms

The most common symptom of Madelung's deformity is a visible deformity of the wrist, which may be present at birth or develop during adolescence. Other symptoms may include pain, limited wrist movement, and decreased grip strength. In some cases, the deformity may be bilateral, affecting both wrists.

Causes

Madelung's deformity is caused by a disruption in the growth of the radius, which leads to a shortening and bowing of the bone. This in turn causes the wrist to tilt towards the thumb (radial deviation). The exact cause of this disruption is not known, but it is believed to be due to a genetic mutation. The condition is more common in females and often occurs in individuals with Leri-Weill dyschondrosteosis, a genetic disorder that affects bone growth.

Diagnosis

The diagnosis of Madelung's deformity is usually made based on physical examination and imaging studies. X-rays of the wrist can show the characteristic changes in the radius and other bones of the wrist. In some cases, genetic testing may be performed to confirm the diagnosis and identify any associated genetic disorders.

Treatment

The treatment of Madelung's deformity depends on the severity of the symptoms and the degree of deformity. Non-surgical treatments may include pain management, physical therapy, and the use of braces or splints. In more severe cases, surgery may be required to correct the deformity and improve wrist function. The type of surgery performed depends on the individual's age, the severity of the deformity, and the presence of any associated conditions.
