The Proximal femoral shaft is well padded with powerful muscles
Advantage – This protects the femur from most forces
Disadvantages – This makes the reduction difficult, the displacement is often so severe

Treatment in tractionTreatment in traction
Most femoral shaft fractures except those in upper third can be treated in skeletal traction.
Its ridden with problems, patient needs to stay in bed for 10 to 14 weeks , and all the complication of recumbancy for so long ensue.
It’s a poor choice in elderly, multiple injured and pathologic fractures
