The actual prevalence of Klippel-Feil syndrome is unknown due to the fact that there was no study done to determine the true prevalence. Although the actual occurrence for the KFS syndrome is unknown, it is estimated to occur 1 in 42,000 newborns worldwide. In addition, females seem to be affected slightly more often than males
Treatment for Klippel–Feil syndrome is symptomatic and may include surgery to relieve cervical or craniocervical instability and constriction of the spinal cord, and to correct scoliosis.
The heterogeneity of this syndrome has made it difficult to outline the diagnosis as well as the prognosis classes for this disease. Because of this, it has complicated the exact explanation of the genetic etiology of the syndrome. The prognosis for most individuals is good if the disorder is treated early on and appropriately. Activities that can injure the neck should be avoided, as it may contribute to further damage. Other diseases associated with the syndrome can be fatal if not treated, or if found too late to be treatable.
Although, surgery is an option it’s not highly
