Resumen
La asimetría del ángulo de la articulación facetaria, particularmente en C4/5, está relacionada con la hernia de disco cervical (CDH). La inclinación reducida de la articulación facetaria en C5/6 y C6/7 es una característica clave de CDH.
Área de la Ciencia:
- La ortopedia es la ortopedia.
- Radiología Radiología.
- Anatomía La anatomía es la anatomía.
Sus antecedentes:
- La hernia de disco cervical (CDH) a menudo se asocia con la asimetría articular de la faceta cervical.
- El impacto preciso de los ángulos de las articulaciones facetarias en el CDH sigue sin estar claro, lo que requiere una mayor investigación de las características anatómicas patológicas.
Objetivo del estudio:
- Investigar la relación entre los ángulos sagital e inclinado de las articulaciones faciales cervicales y la aparición de la hernia de disco cervical (CDH).
Principales métodos:
- Un estudio comparativo que involucró a 271 pacientes con CDH de un solo segmento y 132 controles sanos.
- Análisis de ángulos sagitales e inclinados bilaterales de las articulaciones faciales cervicales (C2-C7).
- Comparación estadística utilizando la corrección de Bonferroni y el ajuste por factores de confusión.
Principales resultados:
- Los pacientes con CDH exhibieron ángulos C2-7 Cobb significativamente más bajos y alturas de discos intervertebrales.
- El análisis previo a la corrección reveló mayores diferencias bilaterales y tasas de asimetría en ángulos sagitales e inclinados para pacientes con CDH.
- Después de la corrección, la asimetría del ángulo sagital en C4/5 se mantuvo significativa, mientras que los ángulos inclinados en C5/6 y C6/7 fueron significativamente más bajos en pacientes con CDH, incluso después de ajustar por factores de confusión.
Conclusiones:
- La asimetría del ángulo de la articulación de la faceta sagital en C4/5 está asociada con CDH.
- Un ángulo de inclinación promedio reducido de las articulaciones facetarias en C5/6 y C6/7 es una característica fisiopatológica significativa de la CDH.
- La lordosis cervical y la altura del disco pueden influir en las diferencias de ángulo de la articulación de la faceta sagital en CDH.

01:25Inclination of a Line
299
The inclination of a line describes its angle of tilt with respect to the horizontal axis. While a line itself is an abstract object with no thickness, its orientation on the Cartesian plane is determined by its slope, which reflects how steeply it rises or falls. The inclination angle, always measured counterclockwise from the positive x-axis, varies between zero and π radians for nonhorizontal lines. This angle directly relates to the slope, providing a geometric interpretation of the...

11.1K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

01:11Work Done Over an Inclined Plane

The center-of-mass framework helps to easily describe the work done on rigid bodies. Since the internal forces in a rigid body do no work, they can be ignored, and the external forces can be considered in the work-energy theorem.
The work done by gravity to move a rigid body, or the work done by an opposing force to move a rigid body against gravity, can be calculated using the center-of-mass framework. It is the line integral of the force of gravity over the path, considered positive if...

02:20Correlations
36.6K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

01:27Correlation and Causation
42.9K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

01:16Structural Joints: Synovial Joints
7.2K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
