2024年11月4日 · Although spinal dysraphism can be classified in a variety of ways, most commonly it is broadly divided into two different clinicoradiological entities based on whether or not the skin is intact (closed) or the abnormality communicates through a cutaneous defect (open) with associated loss of CSF 8,9,14:

Based on the presence of external and internal components, they are divided into four types: Type 1: primarily external, type 2: Equal external and internal portions, Type 3: primarily internal, and Type 4: entirely internal.

Spinal dysraphism types. The three most common types of spinal dysraphism are: Myelomeningocele. When people talk about spinal dysraphism, most often they are referring to myelomeningocele or open spina bifida. The spinal canal is open along several vertebrae in the lower or middle back.

What are the different types of spinal dysraphism? There are 4 types of spinal dysraphism. Each type is listed below from least to most severe. Spina bifida occulta: When one or more vertebra (bones in the spine) are malformed (not formed correctly), and a layer of skin covers the opening in the vertebrae.

2021年1月15日 · Spinal dysraphisms (SDs) are congenital malformations of the spinal cord, determined by derangement in the complex cascade of embryologic events involved in spinal development.

2023年12月20日 · The clinical manifestations of closed (occult) spinal dysraphism (see 'Terminology' below) vary widely and range from benign or asymptomatic to severe neurologic, genitourinary, gastrointestinal, or musculoskeletal anomalies. The pathogenesis and types of closed spinal dysraphism will be discussed here.

Spinal dysraphism refers to the congenital abnormalities of the spine and spinal cord. Clinico-radiological classification of spinal dysraphism has been well established and widely followed.

2005年3月1日 · Two forms of spinal dysraphism exist: a closed form referred to as spina bifida occulta, and an open form known as spina bifida aperta. In occult spinal dysraphism, there is a congenital absence of a spinous process and variable amounts of lamina resulting in neural tissue that lies just deep to an intact layer of skin.

2010年9月1日 · Spinal dysraphism comprises an array of congenital anomalies of spinal cord development. Each of the dysraphic disorders can result in neurological, orthopaedic and urological dysfunction. This potentially confusing array of conditions is best understood from the embryological perspective.

What Are the Types of Spinal Dysraphism? Different types of spinal dysraphism are designated as “open” or “closed” depending on whether or not the abnormality is covered with skin. Types of open spinal dysraphism include: Myelomeningocele; Spinal raschisis; Types of closed spinal dysraphism include. Lipomyelomeningocele
