Q

Based on this image, does this patient have an old or a new fracture?

A

new fracture (black is whack, white is right)

2
Q

Based on this image, does this patient have a new or old fracture?

A

old fracture (black is whack, white is right)

3
Q

The patient is 70 years old. What is the dianosis? What are the radiographic features you see?

A

osteoporosis

radiographic features: cortical thinning, resorption of nonstress-bearing trabeculae, accentuated vertical struts, altered vertical shape (codfish deformity), schmorl’s nodes, endplate infractions

4
Q

What is the diagnosis? What are the features you see that make that so?

A

osteopenia

thinner cortex, thinner subchondral region, trabeculation

5
Q

What kind of fracture is this?

A

compression fracture

6
Q

what kind of fracture is this?

A

pathological fracture

7
Q

What is the radiographic feature?

A

codfish deformity

8
Q

What is the radiographic feature? How does this occur?

A

Ward’s triangle

occurs when primary and secondary compressive and primary tensile trabecular patterns of the hip wither away at about the same time

9
Q

What is the diagnosis?

A

rib fracture

10
Q

What is the diagnosis?

A

Multiple lytic calvarial lesions associated with mutiple myeloma

punched out lesions

11
Q

A person comes in with this xray. They have just gotten out of a cast. What is the diagnosis?

A

disuse osteoporosis

12
Q

What is the diagnosis? What makes you think so?

A

Reflex sympathetic dystrophy

there is pretty severe demineralization and the joint spaces are good

13
Q

This is an xray film of a 30 year old female. What is the possible diagnosis?

A

transient osteoporosis of the hip

14
Q

What is the diagnosis? What radiographic features make that so (features both on the xray and off)?

A

Ostomalacia

osteopenia, coarsened trabeculation, LOOSER LINES, bowing of the femur

basilar invagination, acetabular protrusion

15
Q

What is the diagnosis? What makes you think so?

A

Rickets

osteopenia, paintbrush metaphysis, lack of provisional zone of calcification

return of the zone is a sign of healing

fraying, splaying, bowing deformities, rachitic rosary

16
Q

What is the diagnosis? What is the radiographic feature called?

A

rickets

rachitic rosary

17
Q

What is the diagnosis? What are the radiographic features?

A

Scurvey

ring epiphysis (wimberger’s sign), scorbutic zone, dense zone of provisional calcium (farkle’s), pelkin’s sign

18
Q

What is the radiographic feature? This is the most definitive radiographic sign of what disease?

A

subperiosteal resorption, HPT

19
Q

HPT

22
Q

What is the radiographic feature? What disease is this associated with?

Q

What is the possible diagnosis? What radiographic features are associated with this disease?

A
