|
What is the dissection interval for a posterolateral approach to the femur?
|
Vastus lateralis/hamstrings
|
|
|
What is the interval for a posterior approach to the thigh? What is the anteromedial approach to the distal femur?
|
Vastus medialis/rectus
|
|
|
What two structures are at risk with this approach?
|
Medial superior geniculate artery
Infrapatellar branch of the saphenous |
|
|
In patients with a Injury Severity Scale (ISS) score >18, what are the three proven advantages of early stabilization?
|
Decreased rate of acute respiratory distress syndrome (ARDS)
Fewer pulmonary complications Shorter intensive care unit (ICU) stay |
|
|
Intramedullary (IM) nailing releases what two interleukins (ILs)?
|
IL-6
IL-8 |
|
|
It is generally preferred to do IM nailing in most patients early, except those with ____.
|
Closed head injuries (consider external fixator first)
|
|
|
Convert from external fixator to nail by __ days to minimize risk of infection.
|

|
|
What is the main advantage of the IM nail over external fixator in adult femoral fracture?
|
Improved knee range of motion
|
|
|
What is the biomechanical advantage to plate/screw construct for femur fracture? What is the principal disadvantage?
|
Plate/screw fixation results in increased torsional stiffness
Disadvantage: requires more extensive soft tissue stripping |
|
|
In what patient population is reaming not recommended? Is there another consideration?
|
In those with bilateral chest injury
But reaming has not been shown to cause ARDS even with chest trauma |
|
|
What is the preferred proximal locking screw orientation for femoral IM nailing? Why?
|
Oblique preferred
Transverse screws are prone to failure |
|
|
How long after femoral shaft fracture treatment can an athlete return to competition?
|
Can return when circumferential bridging callus is seen on radiograph
|
|
|
What is the preferred treatment of femoral nonunion after nailing? What other alternative might be considered if the nonunion is atrophic?
|
Reamed exchange nailing
If atrophic, ORIF with grafting is an alternative |
|
|
What is the mot frequent complication of IM nailing for femur fracture? Is there another consideration?
|
Heterotopic ossification (HO)
But only very rarely is the HO clinically important |
|
|
What position of malunion is classically seen with a trochanteric starting point for a femoral nail?
|
Varus malunion
|
