What is the definition of spondylosis?
a vertebral condition
What is the definition of spondylolysis?
a vertebral seperation of vertebral cleavage
What is the definition of spondylolisthesis?
a vertebral slipage
What is the current limited definition of spondylosis?
a vertebral condition that is acquired or age-related
What is the location of spondylosis that wil be stressed in Spinal II?
a seperation along the pars interarticularis (defect in the pars interarticularis or pars defect)
What is the incidence of spondylosis in the general population?
a range of 2.6% to 10%
What is the geopraphic or ethnic bias for a higher incidence of spondylosis?
the native Alaskan (inuit) population
What does lumbar spondylosis appear to be related to?
the uniquely human upright stance or erect posture
Lumbar spondylosis is associated with what characteristics?
familial association, spina bifida oculta, racial/ethnic disparities, gender and locational bias, youthful incidence and activites requiring repetitive stress on the spine
Lumbar spondylolysis has not been reported in what groups of individuals?
fetuses, newborns, rarely in children under five years old, patients who have never walked and in non-erect species
What is the age range typically associated with lumbar spondylolysis?
10-20 year olds
What activities are particularly stressful at the pars interarticularis of lumbar vertebrae?
gymnastics, dance, soccer
What fills the space in a lumbar spondylolysis?
fibrocartilaginous material
What name has been given to the material filling the space in a lumbar spondylolysis?
spondylolysis ligament
What types of neural function(s) have been associated with the spondylolysis ligament?
nociception, neuromodulation and autonomi function
What is the apprearance of the lumbar vertebra upon oblique X-ray view?
a Scotty dog
What is the appearance of a spondylolysis in a lumbar vertebra upon oblique x-ray view?
a collared Scotty dog
In an oblique x-ray, spondylolysis below the superior articular process of a lumbar pars interarticularis is associated with what part of the Scotty dog?
the neck of the Scotty dog
What part of a lumbar vertebra forms the eye of a Scotty dog?
the pedicle
What part of a lumbar vertebra forms the ear of a Scotty dog?
the superior articular process
What part of a lumbar vertebra forms the nose of a Scotty dog?
the transverse process
What characteristics are associated with cervical spondylolysis?
rare, congenital, gender bias towards men, msot common at C6 and linked to spondylolisthesis and spina bifida
What characteristics are associated with sacral spondylolysis?
rare in the general population, within typical percents in the native Alaskan (Inuit) population, seems tpo be acquired, gender bias towards men, most common at S1 and linked to activities suck as kayaking and harpooning
What is the incidence of sacral spondylolysis in the general population?
its rare
Is sacral spondylolysis the result of congenital conditions, acquired conditions or an age-related conditions?
it seems to be acquired
What is the ethnic, gender, and locational bias associated with scaral spondylolysis?
the native Alaskan (Inuit) male at the S1 level
Identify all names given to type III spondylolisthesis?
degenerative spondylolisthesis
What is the locational bias of type I spondylolisthesis?
L5 or upper sacral segments
What additional conditions are linked to type I spondylolisthesis?
spina bifida occulta and nerve root compression of the S1 nerve
Which subtype of type II spondylolisthesis is stressed in Spinal II?
lytic spondylolisthesis or stress fracture induced spondylolisthesis
What is the cause of most frequently given for type II spondylolisthesis?
microfractures as the result of reptitive stress during hyperflexion and rotation
What is the age group typically associated with type II spondylolisthesis?
teenagers or young adults
What gender bias,locational bias, and spinal cancal dimensions are associated with type II spondylolisthesis?
isthmic spondylolistheses is common in men, located at the L5/S1 level and demonstrates an increase in sgaittal diameter of the spinal cord
What causes type IV spondylolisthesis?
fracture of the nerual arch components
What are the cause(s) associaed with type V spondylolisthesis?
bone diseases such as Paget disease or osteogenesis imperfecta
