Klippel-Feil Syndrome is a rare congenital condition characterized by the fusion of two or more cervical vertebrae in the neck. This fusion can lead to a limited range of motion, neck pain, and other complications. The syndrome may also be associated with other skeletal abnormalities and can vary in severity among individuals. People with Klippel-Feil Syndrome may experience additional health issues, such as hearing loss or heart defects. Diagnosis typically involves imaging studies like X-rays or MRI to assess the spine's structure. Treatment focuses on managing symptoms and may include physical therapy or surgery in severe cases.
