What names are given to conditions associated with abnormal curves of the vertebral column?
Lordosis
Kyphosis
Scoliosis
What is the definition of lordosis?
Forward bending condition
What is the definition of kyphosis?
Humpback or hunchback condition
What is the definition of scoliosis?
Warped or crooked condition
What is the direction of the curve deviation in lordosis?
To the anterior
What is the direction of the curve deviation in kyphosis?
To the posterior
What clinical examples of abnormal curvatures along the vertebral column were stressed in class?
Military neck
Humpback or hunchback
Swayback
What are the curve classifications for military neck?
Kyphosis or hypolordotic curve
What are the curve classifications for humpback or hunchback?
Kyphosis or hyperkyphotic curve
What are the curve classifications for swayback?
Lordosis or hyperlordotic curve
What is the more complete, accepted definition of scoliosis?
Abnormal lateral curve coupled with axial rotation
What are the classifications of scoliosis according to the Scoliosis Research Society?
Magnitude Location Direction Etiology Structural scoliosis Non-structural scoliosis
What does magnitude of scoliosis refer to?
Length and angle of the curve deviation on x-ray
What does location of scoliosis infer?
Location on the vertebral segment forming the apex of the curve deviation
What does direction of scoliosis refer to?
Side of convexity of the curve will bend toward
What does the etiology of scoliosis mean?
Cause of scoliosis
What is the classification of scoliosis that is unique to the individual patient?
Idiopathic scoliosis
What is the incidence of idiopathic scoliosis in the population?
1% to 4% of the population
Based on age of onset, what are the types of idiopathic scoliosis?
Infantile
Juvenile
Adolescent
What is the age range for infantile idiopathic scoliosis?
From birth to 3 years old
What is the age range for juvenile idiopathic scoliosis?
From 3 years old to 10 years old
What is the age range for adolescent idiopathic scoliosis?
Over 10 years old
Identify the curve direction, location, gender bias, and incidence of infantile idiopathic scoliosis.
Left thoracic
Male
Less than 1% incidence
Identify the curve direction, location, gender bias, and incidence of juvenile idiopathic scoliosis.
Right thoracic
Females over 6 years old
12%-21% incidence
Identify the curve direction, location, gender bias, and incidence of adolescent idiopathic scoliosis.
Right thoracic or right thoracic and left lumbar
Females
80% incidence
What is the genetic factor associated with adolescent idiopathic scoliosis?
Autosomal dominant factor that runs in families
What is the relationship between curve deviation, incidence, and curve worsening?
Greater the deviation, the lower the incidence, and more likely to worsen
