Name the two types of DDD?
1. Spondylosis deformans
2. Intervertebral osteochondrosis
Which type of DDD typically has severe disc space narrowing?
IVOC - intervertebral osteochondrosis
True/False?
Spondylosis deformans involves major osteophytic change and most importantly, major loss of disc space
False
SD = major osteophytic change, little to no loss of disc space
Between Spondy Deformans and IVOC, which mostly involves changes with the vertebral body?
Spondy Deformans
Where are the most frequently involved segments in the cervicals? MACA
a. C1-C2
b. C2-C3
c. C6-C7
d. C3-C4
e. C5-C6
C, E
C5-C6, C6-C7
In DDD, what causes the pseudofracture view in a lateral cervical film?
(hint: name the structure and the specific change it undergoes)
Uncinate Hypertrophy (causes an overlapping shadow)
or "uncinate arthrosis"
A free-floating calcification of stripped annulus fibrosis commonly seen in the cervicals is called an __________ bone.
intercalary
What feature is often displayed on a patient with DDD in the thoracic area?
osteophyte on anterior to anterior right side of body m/c
What causes thoracic osteophytes to generally be on the right side of the vertebrae?
The aorta on the left
What is the name of the syndrome involving a pseudovisceral abdominal pain associated with DDD in the costovertebral & costotransverse joints?
Robert's syndrome
What are the most common involved segments in DDD in the lumbar spine? (hint: 2 of them)
L4/5 and L5/S1
Regarding DDD, what vertebral areas are most common to have symptoms?
a. cervicals
b. thoracics
c. lumbars
d. sacral
e. two of the above
c. lumbars
What is the A-P view that best shows whether DDD is present or not in L5-S1? (hint: 2 names possible)
Ferguson view
Spot shot
(key is to know that you need a different view than normal A-P to see L5-S1 unlike the other lumbars)
Small tears (causing a vacuum phenomenon) in Sharpey's fibers are also called what? (starts with an R)
Rents
What type of DDD category is most likely to have a visible vacuum cleft?
a. spondy deformans
b. IVOC
IVOC
What type of modic change is visible when you start to see fibrofatty infiltration in the vertebral body?
a. type 1
b. type 2
c. type 3
b. type 2
What modic change is involved when you see Hemispherical Spondylosclerosis?
a. type 1
b. type 2
c. type 3
c. type 3
What imaging modality is necessary to see the modic changes in DDD?
a. conventional radiograph
b. CT
c. MRI
d. Bone Scan
e. more than one of the above
c. MRI
What signal is present when looking at a Type 1 Modic change on T1 MRI? How about T2 MRI?
T1 - Low signal
T2 - High signal
What signal is present when looking at a Type 2 Modic change on T1 MRI? How about T2 MRI?
T1 - High signal
T2 - Low signal
What signal is present when looking at a Type 3 Modic change on T1 MRI? How about T2 MRI?
T1 - Low signal
T2 - Low signal

Type 1 = Low, High
Type 2 = High, Low
Type 3 = Low, Low
What is the most common joint abnormality seen today?
OA - osteoarthritis
True/False?
With osteoarthritis, there is no primary inflammation present.
True
True/False?
With OA, there is no inflammation present.
False - it CAN be present, but it is never primary. It's because of resultant secondary effects.
In DJD ,what is the cell type that is initially affected? (hint: _______cyte)
chondrocyte
What is the order (from most-likely to least-likely joint) you see DJD present in?
a. ankle
b. knee
c. hip
d. shoulder
B, C, A, D
knee, hip, ankle, shoulder
Put into order what happens in the DJD process.
a. ground substance degrades
b. cartilage shedding
c. joint space narrowing
d. chondrocyte dysfunction
e. diminshed GAG's concentration
d, e, a, c, b
What is the term used to describe bone's normal reaction to "bone-on-bone" repeated contact and injury? (2 words, starts with S)
subchondral sclerosis
Loose bodies found as a result of DJD is known as synovial _____________.
chondrometaplasia
When cartilage is worn away and synovial fluid invaginates bone (love that word).. What is the term for this phenomenon?
subchondral cysts
What 2 joints in the cervical vertebrae are synovial and can cause nerve or artery entrapment in DJD?
Uncovertebral joint
Facet joint (superior/inferior)
In a patient with DJD, what are some diseases or clinical manifestations that might indicate weakness in the vertebral artery? (in other words, DJD + what = chance of stroke!)
