How many cases of congenital radioulnar synostosis are there?

Congenital radioulnar synostosis is rare, with approximately 350 cases reported in journals, and it typically affects both sides (bilateral) and can be associated with other skeletal problems such as hip and knee abnormalities, finger abnormalities (syndactyly or clinodactyly), or Madelung’s deformity.

Is congenital radioulnar synostosis a disability?

The condition can lead to significant disability, especially if there is hyperpronation or when it is bilateral, as occurs in 50% to 80% of cases.

What is congenital proximal radioulnar synostosis?

Congenital proximal radioulnar synostosis is a rare malformation of bone development characterized by the fusion of the proximal radius and ulna. This malformation usually occurs bilaterally and is diagnosed before the patient is 5 years old.

What is congenital synostosis?

What is the diagnosis of congenital radial ulnar synostosis?

Congenital Radial Ulnar Synostosis is a congenital condition caused by failure of differentiation that leads to the presence of a bony bridge between the proximal radius and ulna. Diagnosis is made radiographically with the presence of a proximal radial ulnar bony connection.

How many people have Congenital radioulnar synostosis?

Summary Summary. Congenital radioulnar synostosis is a rare condition in which there is an abnormal connection (synostosis) of the radius and ulna (bones in the forearm) at birth. The condition is present in both arms (bilateral) in approximately 60% of cases.

Is it possible to have synostosis in both arms?

Congenital radioulnar synostosis is a rare condition in which there is an abnormal connection (synostosis) of the radius and ulna (bones in the forearm) at birth. The condition is present in both arms (bilateral) in approximately 60% of cases.

What happens in type 2 radioulnar synostosis?

In type 2, the fusion is farther from the elbow and there is dislocation of the radial head. Both types result in a limitation of inward roll (pronation) and outward roll (supination) of the forearm, and in type 2 there is also a restriction of extension at the elbow. [3]
