Is Klippel-Feil syndrome fatal?
Some cases of KFS can become serious and potentially life-threatening in a few different ways: Cervical myelopathy. If the spinal cord starts to become compressed, such as from bony overgrowths or severe spinal deformity, problems with coordination and reduced control over bodily functions could result.
What are the signs and symptoms of Klippel-Feil syndrome?
Some of the more common signs and symptoms of KFS include:
- Visibly shortened neck and/or low hairline behind head.
- Reduced neck mobility.
- Neck pain.
- Cervical radiculopathy.
- Cervical myelopathy.
What is hypoplastic disc?
In optic nerve hypoplasia, optic disc is often pale or gray and appears to be half the size of a normal optic disc or smaller. Optic discs often present with a double ring sign – yellow to white ring around the disc.
What does hypoplastic mean?
: a condition of arrested development in which an organ or part remains below the normal size or in an immature state. Other Words from hypoplasia. hypoplastic \ -ˈplas-tik \ adjective.
Is KFS hereditary?
Most likely, KFS is multifactorial, which means that several different factors including genetic factors all play some causative role. In addition, different genetic defects can cause KFS (genetic herterogeneity) in different people.
Is Klippel-Feil syndrome a birth defect?
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.
What is a hypoplastic disc at L5 S1?
L5 hypoplasia is frequently associated with L4–L5 and L5–S1 disc desiccation and pseudodisc bulge in inferior and superior directions respectively, without causing spinal canal stenosis or thecal sac indentation.
Can you be born with a thin optic nerve?
Epidemiology. Optic nerve hypoplasia (ONH) is a congenital condition in which the optic nerve is underdeveloped (small). Many times, de Morsier’s Syndrome or septo-optic dysplasia (SOD) is associated with ONH, however, it is possible to have ONH without any additional issues like SOD.
How is hypoplasia treated?
Enamel Hypoplasia Treatment Some cases may require cosmetic adjustments such as bleaching to match the discolored tooth to the whiter, unaffected teeth. For more serious conditions, your dentist may recommend a sealant, filling or crown.
Why have I got a short neck?
Short neck is associated with a host of musculoskeletal abnormalities of the neck and skull. Torticollis is a frequent association, wherein the odontoid process is eccentrically poised. Abnormal bone fusions of the cervical spine include assimilation of atlas, C2-3 fusion, and Klippel-Feil abnormalities.
Can KFS be fixed?
There is no cure for Klippel-Feil syndrome (KFS), so treatments focus on managing the symptoms. Treatment programs can vary widely, depending on the severity of KFS, as well as any other conditions that might be present.
What is a hypoplastic nerve?
Optic nerve hypoplasia (ONH) is a congenital disorder characterized by underdevelopment (hypoplasia) of the optic nerves. The optic nerves transmit impulses from the nerve-rich membranes lining the retina of the eye to the brain.
Is Klippel-Feil syndrome reversible?
Is there treatment for Klippel-Feil syndrome?
There is no cure for Klippel-Feil syndrome. Treatment is ordered when certain issues — such as spinal curvatures, muscle weaknesses or heart problems — occur and need to be treated.
What is a hypoplastic disc?
What is cervical hypoplasia?
Cervical hypoplasia is when a girl is born with a cervix that is smaller than normal. The cervix is the lower part of the uterus, sometimes called the “neck,” that connects the uterus to the vagina. Patients can be seen by Texas Children’s experts in Pediatric and Adolescent Gynecology.
What is a herniated cervical disc?
With age, the cervical discs lose water, stiffen and become less flexible in adjusting to compression. Such degenerative changes may result in a herniated cervical disc, which is when the disc’s inner core extrudes through its outer layer and comes in contact with the nerve root and/or spinal nerve.
What is Cervical degenerative disc disease?
Cervical Degenerative. Disc Disease Video. A vertebral endplate is the transition region between a disc and the adjacent vertebra. The vertebral endplate is thin and comprised of collagen and cancellous bone, which allows for nutrients and limited amounts of blood to pass into the disc.
Does cervical disc arthroplasty lead to adjacent segment degeneration?
Cervical disc arthroplasty has emerged as a promising potential alternative to anterior cervical discectomy and fusion (ACDF) in appropriately selected patients. Despite a history of excellent outcomes after ACDF, the question as to whether a fusion leads to adjacent segment degeneration remains unanswered.
