Vertebral Column: Regions and Curvature

5.8K
The vertebral column or spine is a flexible column that supports the head, neck, and body and  allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

General Structure of a Vertebra

5.9K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

Deformation of Member under Multiple Loadings

423
When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...

Spinal Cord: Cross-sectional Anatomy

4.1K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
Gray Matter and its Components
Central to the gray matter is...

Resumen

Los adultos con deformidades espinales pueden tener una columna vertebral inclinada, caracterizada por una mala alineación y una reducción de la calidad de vida. Esta condición se asocia con una mayor incidencia pélvica y una menor cifosis torácica.

Área de la Ciencia:

  • Cirugía de columna
  • Ortopedia
  • Radiografía

Sus antecedentes:

  • Algunas deformidades espinales del adulto se presentan como una columna vertebral inclinada, no como cifosis, con una desalineación significativa.
  • Esta desalineación se asocia con una disminución de las medidas de resultados informadas por el paciente (PROMs).

Objetivo del estudio:

  • Definir las deformidades espinales de tipo inclinado utilizando parámetros radiográficos.
  • Correlacionar estos hallazgos radiográficos con las PROMs.

Principales métodos:

  • Se incluyeron participantes con un eje vertical sagital (SVA) >40 mm de un programa de detección de salud.
  • Se definió la deformidad de tipo inclinado (grupo S) basándose en la alineación de la pared vertebral posterior en relación con una línea sacra vertical.
  • Se midieron parámetros radiográficos (SVA, TK, LL, ángulo L4-S, PI, PT) y el índice de discapacidad de Oswestry (ODI).

Principales resultados:

  • 50 de 348 participantes (14,4%) presentaron deformidades de tipo inclinado (grupo S).
  • El grupo S exhibió un SVA, PI, PT, PI-LL significativamente más altos y una TK y un ángulo L4-S más bajos en comparación con el grupo no S.
  • El grupo S reportó puntuaciones ODI significativamente peores, lo que indica peores resultados.

Conclusiones:

  • Las deformidades de tipo inclinado se asocian con un aumento de la incidencia pélvica (PI), una peor alineación espinopélvica y peores resultados informados por el paciente.
  • Una PI más alta, la anterolistesis lumbar y una TK y un ángulo L4-S más bajos son factores significativos que contribuyen a las deformidades de tipo inclinado.
