25
What is a stress fracture
Injuries to vertebra happen faster or more often than the body can keep up with needed repairs, a crack may form in the weakened bone
26
If the crack in the vertebra reaches both sides what happens
The vertebra is no longer held firmly in place by the facet joints allowing for the body to slip anterior
27
Spondylolisthesis in early stages is unstable but then becomes stable due to what
Fibrous tissue forming
28
True congenital spondylolisthesis occurs with who and when
Pars defects increases with age
29
What are the five types of spondylolisthesis
Isthmic, degenerative, traumatic, pathological and dysplastic
30
Aka of isthmic spondylolisthesis
Lytic spondylolisthesis
31
What is isthmic spondylolisthesis
Fatigue or stress fracture of the pars of L5, L5 slips on S1
32
What is the most common type of spondylolisthesis
Isthmic
33
Most common spondylolisthesis below age 50
Isthmic
34
What is degenerative spondylolisthesis
Fracture/pars defect but is secondary to long standing degenerative process
35
Degenerative spondylolisthesis primarily what type of degeneration
Posterior joint
36
Who do you see degenerative spondylolisthesis with
Female over 40
37
Degenerative spondylolisthesis is a slippage on what
L4 slips on L5
38
Degenerative spondylolisthesis is most common with what age
Above age 50
39
What is traumatic spondylolisthesis
Acute fracture anywhere in the posterior arch except at the pars interarticularis
40
What is pathological spondylolisthesis
Found secondary to pathology such as metastatic carcinoma, Paget’s disease, etc.
41
What is dysplastic spondylolisthesis
Rare congenital malformation in which L5 may be lacking inferior articular processes to articulate with S1 thus slides anterior
42
Dysplastic spondylolisthesis AKA
Congenital spondylolisthesis
43
Both spondylolysis and spondylolisthesis are considered __________ conditions
Acquired
44
What percentage of population has spondylolisthesis
5 to 7%
45
Is canal stenosis more common or foraminal stenosis
Foraminal stenosis
46
As many as 50% of young athletes have this symptom which may indicate they have spondylolysis or spondylolisthesis
Pain in the lumbar for over three months
47
Spondylolisthesis is most often associated with sports that have a lot of
Hyperextension such as football, weight lifters, divers, pole vaulters, high jumpers, gymnastics and wrestlers
48
Isthmic spondylolisthesis is most often found between what ages in athletes
9 and 13
49
The majority of spondylos occur asymptomatically by what age and symptomatic at what age
12 and 13
50
What sex is more prone to spondylolisthesis in sports
Males
51
What sex appears to be severe with spondylolisthesis in sports
Females
52
Signs and symptoms of spondylos
Low back pain (chronic), tight hamstrings causing hyperlordosis, loss of flexibility (due to altered biomechanics and pain)
53
Typical X-ray views for the lumbar spine
A-P lumbar and lateral lumbar
54
If you suspect spondylo, what X-ray series
A-P lumbar, lateral lumbar, and obliques
55
What X-ray do you use to measure or grade the amount or degree of slippage in spondylolisthesis

51 to 75% anterior slippage
63
Grade 4 meyerding
76 to 99% anterior slippage
64
Grade 5 meyerding
Vertebra has slipped totally off the segment below and anterior to it and may fuse to the segment below called spondyloptosis

67
What is the least segmental motion in the lumbar spine
Rotation
68
Greatest amount of overall motion in the lumbar spine occurs where

L5/S1
71
What is the most common anomaly of the spine
Trophism
72
What is baastrup’s disease
Kissing spinouses
73
What is trophism
Asymmetrical facets at L5/S1
74
What is sacralization
Last lumbar assumes the characteristics of the sacrum, spatulated TVP or fusion to sacrum in some form
75
What is lumbarization
First sacral segment assumes characteristics of the lumbar. Usually separated and called L6
76
Disc herniations occurs where in the L spine
L4/L5 and L5/S1
77
If more mobility then less
Stability
78
What is knife clasp syndrome
Elongated spinous process of L5 (with hyperlordosis) and a spina bifida at S1
79
Symptom of knife clasp syndrome
Will have pain upon extension that is centrally located
80
What occurs in tropism
Joints are faced different and only move with great stress which leads to disc wearing and pain
