1

Which leg is effected more often with Developmental dysphasia of the hip? (DDH) why?

The left due to intrauterine positioning of the hip in adduction against the mothers spine.

2

In children what does hip problems often present as?

Referred pain in thigh or knee

3

Transient synovitis

Inflammatory reaction of the hip joint, occurs after upper respiratory infection

4

What is Leg calve perthes disease? Who is affected more often?

Expression of AVN of the femoral head, boys > girls

5

What are two types of stress fractures?

1. Fatigue fractures
2. Insufficiency fractures

6

What is a fatigue stress fracture?

Result of abnormal stress on normal bone. often associated with athletic activity

7

What is an insufficiency stress fracture?

Result of normal stress on abnormal (demineralized) bone. Often associated with osteoporosis

8

What are the two routine radiologic views of the hip?

1. AP
2. Lateral frog leg

9

In what two ways can trauma be divided into at the pelvis?

1. Low energy injuries (avulsions, individual bone fractures)
2. High energy injuries (Disruption of the pelvic ring, life threatening)

10

How are low energy pelvis injuries evaluated?

Routine projections, most common are AP oblique views of the pelvis

11

How are high energy pelvic injuries evaluated?

High speed CT to obtain TAP or thoracic-abdomen-pelvis series.

12

Major advantage of TAP?

Assess all serious bodily injuries in one time saving intervention

13

Is it practical to employ a large number of sequences for MRI?

No, most facilities have an MRI protocol for the hip which includes certain anatomy and fluid sensitive sequences.

14

What are 3 anatomy defining sequences?

1. T1
2. PD
3. GRE (Gradient echo)

15

What are 2 fluid defining sequences of MRI?

1. T2 fat saturation
2. STIR

16

When is CT used at the hip?

When spatial information about the bones and joint articulations is needed.

17

What must US findings be correlated with in traumatic hips? (2)

1. MOI
2. Radiograph

18

MSUS is ________ _________ imaging. Therefore, the operator can have the patient elicit what?

1. Real time
2. contractions, passive stretching, palpation, lesions not visible in the resting position.
