12 percent
The fractures of the distal femur can be classified into which of the following types?
Supracondylar, intercondylar, and transcondylar

Which of the following is NOT a mechanism of injury for femoral fractures?
Severe valgus or varus forces with axial loading and rotation due to MVA
Fall
Sporting Injury
Repetitive stress activities
What is specific to femoral fractures that differentiates it from other fractures?
The extension deformity caused by the pull of quadriceps

When should arteriography be performed in the context of femoral fractures?
In all cases to ensure proper healing
When there is a suspected infection
In suspected vascular damage or associated dislocation of the knee joint
Only when the patient is symptomatic
What is the initial treatment for an undisplaced unicondylar femoral fracture?
Immediate surgery
Application of a short leg cast
A long leg cast for 3-6 weeks

What is the aim of treatment for intercondylar fractures of the femur?
To minimize the need for physical therapy
