Abos - Hip & Femur - Trauma - Hip: Femoral Side - Femoral Neck Fractures

Front 1

What are the two components of the treatment for compression side femoral neck stress fractures in runner?

Back 1

Cross-training
Stop running

Front 2

What is Pauwel's classification? What is the clinical significance of Pauwel type III?

Back 2

I: fracture line <30 degrees from horizontal
II:<50 degrees
III: <70 degrees (highest rate of osteionecrosis [ON], nonunion)

Front 3

in a femoral shaft fracture with associated neck fracture, what is the typical neck fracture pattern? What is the preferred treatment?

Back 3

Neck fracture often vertical
Treated with DHS (dynamic hip screw)

Front 4

What is the only proven indication for the use of the fourth screw for femoral neck internal fixation?

Back 4

Posterior comminution

Front 5

What two factors increase the risk of osteonecrosis after femoral neck fracture?

Back 5

Increased displacement
Delayed reduction

Front 6

What is the 1-year mortality rate for elderly patients with femoral neck fractures?

Back 6

30%

Front 7

Do cemented or uncemented hemiarthoplasties have better published outcomes for femoral neck fracture treatment?

Back 7

Cemented

Front 8

What patients should undergo a THA for fracture? What is the significance of acetabular wear? What complication is particularly common when a THA is performed for fracture?

Back 8

Active elderly
Regardless of acetabular wear
Complication: increased dislocation rates

Front 9

What two factors principally determine how much sliding occurs with a dynamic hip screw?

Back 9

Screw angle
Length of the screw in the barrel

Front 10

What complication is most common with cephalomedullary nailing than with a dynamic hip screw for a standard intertrochanteric fracture?

Back 10

Lag screw cutout
