Abnormal Curvatures of the Spinal Column Flashcards
Does “osis” infer a normal or an abnormal condition?
Neither, it is non-judgmental
What names are given to conditions associated with abnormal curves of the vertebral column?
- lordosis
- kyphosis
- scoliosis
What is the definition of lordosis?
A forward bending condition
What is the definition of kyphosis?
A humpback or hunchback condition
What is the definition of scoliosis?
A 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 is the direction of the curve deviation in scoliosis?
To the side (it is a lateral deviation)
Is there a locational bias for the classic definition of lordosis?
No, there would be:
- an increase in the anterior direction in the cervical spine
- a decrease in the posterior direction in the thoracic spine
- an increase in the anterior direction in the lumbar spine
- a decrease in the posterior direction in the pelvic or sacrococcygeal region
Is there a locational bias for the classic definition of kyphosis?
No, there would be:
- a decrease in the anterior direction in the cervical spine
- an increase in the posterior direction in the thoracic spine
- a decrease in the anterior direction in the lumbar spine
- an increase in the posterior direction in the pelvic or sacrococcygeal region
What clinical examples of abnormal curvatures along the vertebral column were stressed in class?
- military neck
- humpback or hunchback
- swayback
What is military neck?
- A decreased anterior curve in the cervical region, a straight neck
- example of kyphosis
What is humpback or hunchback?
- An increased posterior curve in the thoracic region
- example of kyphosis
What is swayback?
- An increased anterior curve in the lumbar region
- example of lordosis
What does the use of the term lordotic try to imply?
A normal cervical and normal lumbar anterior curve
What does the use of the term kyphotic try to imply?
A normal thoracic/dorsal and normal pelvic/sacrococcygeal posterior curve
What prefixes are used to convey abnormality in curve patterns
hyper and hypo
What does the term hyperlordotic infer?
an increase in the anterior curve of the cervical or lumbar region
What does the term hypolordotic infer?
a decrease in the anterior curve of the cervical or lumbar region
What does the term hyperkyphotic infer?
an increase in the posterior curve of the thoracic/dorsal or pelvic/sacrococcygeal region
What does the term hypokyphotic infer?
a decrease in the posterior curve of the thoracic/dorsal or pelvic/sacrococcygeal region
What is the more complete, accepted definition of scoliosis?
an abnormal lateral curve coupled with axial rotation
What is the relationship between degrees of lateral curve deviation, axial rotation, and care?
- curves with 10-20 degrees of lateral deviation and a fixed angle of trunk rotation have scoliosis
- curves with 20-30 degrees of lateral deviation and a fixed angle of trunk rotation of 5 degrees require attention
- curves with 30-50 degrees of lateral deviation and a fixed trunk rotation of 7 degrees require intervention as they have a 60% chance to worsen
- curves with greater than 50 degrees of lateral deviation have a 90% chance to worsen
What is the radiological test for skeletal maturity?
- the Risser sign
- an indication of bone maturity in the iliac apophysis
