3% [5][6] Scoliosis (pl.: scolioses) is a condition in which a person's spine has an irregular curve. [2] The curve is usually S- or C-shaped over three dimensions. [2][7] In some, the degree of curve is stable, while in others, it increases over time. [3] Mild scoliosis does not typically cause problems, but more severe cases can affect ...
The management of scoliosis is complex and is determined primarily by the type of scoliosis encountered: syndromic, congenital, neuromuscular, or idiopathic. [1] Treatment options for idiopathic scoliosis are determined in part by the severity of the curvature and skeletal maturity, which together help predict the likelihood of progression.
AIS is the most common form of idiopathic scoliosis, accounting for around 90% of all cases. [51][44] Adolescent Idiopathic Scoliosis affects between 1-4% of teenagers, [52][53] with treatment being required for only 0.25% of teenagers with the condition. An even smaller portion of individuals may die due to the severe curvature as well as the ...
Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These differences are caused by the effects of the different sex chromosome complement in males and females, and differential exposure to gonadal sex hormones during development. Sexual dimorphism is a term for the ...
The neuroscience of sex differences is the study of characteristics that separate brains of different sexes. Psychological sex differences are thought by some to reflect the interaction of genes, hormones, and social learning on brain development throughout the lifespan. A 2021 meta-synthesis led by Lise Eliot found that sex accounted for 1% of ...
The Cobb angle is named after the American orthopedic surgeon John Robert Cobb (1903–1967). It was originally used to measure coronal plane deformity on radiographs with antero - posterior projection for the classification of scoliosis. [9] It has subsequently been adapted to classify sagittal plane deformity, especially in the setting of ...
Sex differences in humans have been studied in a variety of fields. Sex determination generally occurs by the presence or absence of a Y chromosome in the 23rd pair of chromosomes in the human genome. Phenotypic sex refers to an individual's sex as determined by their internal and external genitalia and expression of secondary sex characteristics.
Neurogenic claudication (NC), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord. [1][2] Neurogenic means that the problem originates within the nervous system. Claudication, from Latin claudicare 'to limp ...
