Proximal radio-ulnar synostosis is an upper limb skeletal malformation characterized by bony fusion at the proximal aspect of the radius and ulna. Of the radio-ulnar synostoses, the proximal third is considered the most common site.
It is often congenital but can rarely result following trauma. A developmental relationship between posterior dislocation of the radial head and proximal radioulnar fusion has been suggested by some authors.
