Muscloskeletal Radiology - slides 33-44

Question 1

Name this type of fracture.

Answer 1

Colles fracture.

Question 2

What type of fracture is a posterior displacement, where the wrist slides over the arm?

Answer 2

Colles Fracture

Question 3

Name this type of fracture.

Answer 3

Smith Fracture.

Question 4

Fracture that is displaced ventrally, where the wrist (distal radius) slides underneath the arm. Also known as a “reversed Colles’ fracture”.

Answer 4

Smith Fracture.

Question 5

Fracture of the 5th metacarpal bone.

Answer 5

Boxer fracture.

Question 7

This fracture is difficult to initially diagnose, it can take up to two weeks. The patient experiences pain in the Snuffbox (between the base of the thumb and the radius; depressed area best seen with abduction of thumb).

Answer 7

Scaphoid fracture

Question 8

Damaging the anatomical _________ causes damage to radial artery and scaphoid bone.

Answer 8

Snuffbox.

Question 9

Name structures 1, 2, and 3 of the hip and pelvis.

Answer 9

1. Pubic symphysis
2. Obturator foramen
3. Ischial tuberosity

Question 10

Name structures 4, 5, and 6 of the hip and pelvis.

Answer 10

4. Femoral neck
5. Femoral shaft
6. Lesser trochanter

Question 11

Name structures 7, 8, and 9 of the hip and pelvis.

Answer 11

7. Femoral neck
8. Greater trochanter
9. Lunate surface of the acetabulum

Question 12

Name structures 10, 11, and 12 of the hip and pelvis.

Answer 12

10. Acetabular fossa
11. Ileopectineal line
12. Fovea of femoral head

Question 13

What type of image is this?

Answer 13

Normal AP pelvis

Question 14

This fracture occurs when the head of the femur is driven into the pelvis. This fracture, along with isolated fractures of the ilium, ischium, pubis, or ilium are stable.

Answer 14

Acetabular fracture

Question 15

In this type of fracture, the ring is broken in two places (the ring is open). This causes disruption of the pubic symphysis.

These fractures occur in pubic symphisis or sacrioiliac joints.

Answer 15

Open book fracture.

Question 16

Is this a normal hip bone or a dislocated hip bone?

Answer 16

Normal hip bone.

Question 17

Hip dislocations are either anterior or posterior. This particular dislocation comprises the majority of traumatic dislocations.

Answer 17

Posterior hip dislocation

Question 18

In approximately 90% of hip dislocation patients, the thighbone is pushed out of the socket in a backwards direction. This dislocation leaves the lower leg in a fixed position, with the knee and foot rotated in toward the middle of the body.

Answer 18

Posterior hip dislocation

Question 19

The arrow in the MRI is pointing to what?

Answer 19

Trochanteric Bursitis

Question 20

This is the most common bursitis of the hip. Inflammation of the bursa, which lies over your femur.

Answer 20

Trochanteric Bursitis

Question 21

This image is a fracture of the?

Answer 21

Hip

Question 22

This image shows ______, which is death of bone tissue due to a lack of blood supply. Also called osteonecrosis, avascular necrosis can lead to tiny breaks in the bone and the bone’s eventual collapse. The hip is the joint most commonly affected by this.

Answer 22

Avascular necrosis

Question 23

In a normal hip, the ball at the upper end of the thighbone (femur) fits firmly into the socket, which is part of the large pelvis bone. In babies and children with this condition, the hip joint has not formed normally. The ball is loose in the socket and may be easy to dislocate.

The socket (acetabulum) is shallow, meaning that the ball of the thighbone (femur) cannot firmly fit into the socket. Sometimes, the ligaments that help to hold the joint in place are stretched. The degree of hip looseness, or instability, varies among children with this condition.

Answer 23

Congenital hip dislocation
Developmental Hip Dysplasia (DDH)

Question 24

This image is a fracture of the ___. .

Answer 24

Femur. Midshaft: importance of good films, which include both joints, and an AP and lateral view.

Question 25

The longest and strongest bone in the body, takes a lot of force to break it. Car crashes are the number one cause of these fractures.

Answer 25

Femur

Question 26

The long straight part of the femur is called the _____. When there is a break anywhere along this length of bone, it is called a _______ fracture.

Answer 26

Femoral shaft.

Question 27

a. This image is of a ______ of the lower extremities, originating from the muscles of the inner thigh.
b. What type of imaging is this?

Answer 27

a. Tumor
b. CT image of a sarcoma.
