Question 2

Spondylolyis

Answer 2

• “lysis”= a crack, stress fracture, also called a Pars Stress reaction

Question 3

Spondylolisthesis

Answer 3

stress fracture worsens, the vertebral body slips forward off of the vertebral below.

Question 4

Wiltse’s Classification

Answer 4

Dysplastic-congenital abnormality of upper sacrum

Spondylolytic- a pars lesion

Degenerative- pars, facet instability

Traumatic- non-pars fracture

pathologic-

Question 5

Pars Interarticularis Breaks

Answer 5

“Scotty Dog Fracture”, mainly from hyperextension forces, during sudden growth spurt, increased training intensity, poor posture (tight hip flexors)
common in football and gymnastics

Question 6

Lumbar Biomechanics

Flexion, extension, N SB, R Rotation, (FB/BB) SB

Answer 6

Flexion- facets upglide
Extension- facets downglide
Neutral SB right- L facet=gaps, R facet = compressed
R Rotation- RFa= gap, LFa= close
SB from FB- Isp SB/rotation
SB from BB- isp SB/rotation
