This study on scoliosis found vertebral body wedging increases with curve severity, aligning with existing research. However, inflection points on the convex side, not concave, were observed, suggesting wedging impacts vertebral endplates.
Area of Science:
- Orthopedics
- Biomedical Engineering
- Radiology
Background:
- Scoliosis is a complex spinal deformity characterized by vertebral wedging.
- Understanding vertebral body wedging is crucial for assessing scoliosis severity and progression.
Purpose of the Study:
- To describe vertebral body wedging in a rare, severe scoliotic specimen.
- To investigate the relationship between Cobb angle and vertebral wedging.
Main Methods:
- Morphometric analysis of a complete scoliotic specimen with a 150-degree Cobb angle.
- 3D-computer graphics modeling to measure wedging in frontal, sagittal, and 3D planes.
- Measurement of vertebral body height variation.
Main Results:
- Vertebral body wedging increased progressively with vertebral level, peaking at 27 degrees at the apex.
- Measured wedging correlated with the Cobb angle, consistent with Perdriolle's findings.
- Inflection points were identified on the convex side of the vertebral end plate, contrasting with prior literature.
Conclusions:
- The relationship between Cobb angle and vertebral body wedging holds even for extreme curve angles.
- The identification of convex-sided inflection points suggests vertebral wedging significantly affects vertebral endplates.
- Further research is needed to elucidate the precise mechanisms of vertebral endplate deformation in severe scoliosis.

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 the...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
