Which is characteristic feature of Klippel-Feil syndrome?
What is Klippel-Feil syndrome? Klippel-Feil syndrome is a rare bone disorder distinguished by the abnormal fusion of two or more bones in the neck. Children with the disorder may have a short, webbed neck, decreased range of motion in the head and neck area, and/or a low hairline at the back of the head.
What is the classic triad of Klippel-Feil?
It has been propagated that KFS patients exhibit the “clinical triad” findings, known as a short neck, low posterior hairline, and a limited cervical range of motion (ROM), which aids in the identification of this syndrome [2, 3].
What is a Klippel-Feil deformity?

Klippel-Feil Syndrome is a rare disorder characterized by the congenital fusion of two or more cervical (neck) vertebrae. It is caused by a failure in the normal segmentation or division of the cervical vertebrae during the early weeks of fetal development.
Why does the bone behind my neck sticks out?
Poor posture with a forward bend can weaken your upper back muscles and create a hump at the base of your neck. This condition, which doctors call kyphosis, is more commonly known as dowager’s hump.
What is it called when a person has no neck?
Klippel–Feil syndrome (KFS), also known as cervical vertebral fusion syndrome, is a rare congenital condition characterized by the abnormal fusion of any two of the seven bones in the neck (cervical vertebrae).
Is Klippel-Feil syndrome a neural tube defect?

Rarely, structural brain abnormalities or a type of birth defect that occurs during the development of the brain and spinal cord (neural tube defect) can occur in people with Klippel-Feil syndrome.
Is KFS progressive?
Surgical treatment of KFS is indicated in a variety of situations. As a result of fusion anomalies and the difference in growth potential of the anomalous vertebral bodies, deformity may be progressive. Instability of the cervical spine can develop because of craniocervical abnormalities.
What is Wildervanck syndrome?
Wildervanck syndrome is a condition that affects the bones in the neck, the eyes, and the ears. It is characterized by Klippel-Feil anomaly (in which the bones of the neck fuse together), Duane syndrome (an eye movement disorder), and hearing loss.[99][11459] Wildervanck syndrome occurs primarily in females.
Does Klippel Feil syndrome get worse with age?
KFS symptoms may or may not be apparent at birth or during childhood. However, KFS symptoms typically worsen with age and may become more apparent later in life.
Is there a surgery for KFS?
Surgery for KFS If surgery is performed for KFS, it is typically to stabilize the cervical spine, to correct a spinal deformity, or to take pressure off of nerves or the spinal cord.
Is Klippel Feil syndrome life threatening?
Some cases of KFS can become serious and potentially life-threatening in a few different ways: Cervical myelopathy.
