What is the definition of myelomeningocele?

Myelomeningocele is defined as a type of spina bifida characterized by the herniation of both the spinal cord and the protective membranes (meninges) through a defect in the spine. This condition occurs due to the incomplete closure of the neural tube during fetal development, leading to a significant risk of neurological complications, mobility issues, and other health problems.

In this condition, the protruding membranes and spinal cord can be seen externally, often covered by a thin layer of skin or, in some cases, completely exposed. This herniation can impair the normal functioning of the spinal cord and may result in various disabilities depending on the location and severity of the defect.

Understanding this definition is crucial because myelomeningocele is a serious congenital condition that requires careful management, including surgical intervention and ongoing medical support to optimize outcomes for affected individuals.
