Short neck

This disease was first reported by Klippel and Feil in 1912, also known as short neck deformity, congenital torticollis or congenital cervical fusion deformity, which refers to the fusion of two or more cervical vertebrae. The main manifestation is the shortening of the cervical spine. There are three major clinical features of short neck deformity: short and thick neck, low back hairline, and restricted neck movement. However, not all patients have the above characteristics, and Gray et al believe that only 32% have a typical triad.
