Klippel-Feil syndrome is defined as congenital cervical fusion of cervical vertebra characterized by a triad of a low, posterior hairline, a short neck, and limited neck motion. Klippel-Feil patients with cervical spine fusions above C3 should not participate in contact sports. It is critical that patients undergo a cardiac and renal evaluation upon their diagnosis to look for cardiac septal defects and several different types of renal anomalies.
Patients with congenital cervical fusion may be at an increased risk of sustaining a transient neurologic deficit after minor trauma. Illustration A and B show a radiograph and MRI of a Klippel-Feil patient sustaining a central cord syndrome following a fall during a sporting activity.
