Femoral Shaft Fractures

Nailing, piriformis vs trochanteric, polytrauma timing.

Aug 15, 2026 · 3 refs

At a glance

Femoral shaft fractures are high-energy until proven otherwise in young adults, and a major physiologic hit in polytrauma. Intramedullary nailing is the workhorse when the patient and soft tissues allow.

Length, alignment, and rotation are the technical contract. Traction and starting-point discipline decide whether the nail fixes a good reduction or locks in a bad one.

Decision-making

Screen for open injury, vascular compromise, and ipsilateral femoral neck fracture — miss the neck and you own a disaster. In polytrauma, decide early total care versus spanning external fixation based on physiology.

Isolated closed shafts in resuscitated patients usually proceed to early nailing. Bilateral shafts, severe chest injury, or ongoing instability may favor damage control first.

Treatment

  • Temporary skeletal traction when definitive fixation is delayed
  • Reamed antegrade IM nail for most adult diaphyseal patterns
  • Choose entry (piriformis vs trochanteric) by anatomy, fracture location, and surgeon familiarity — both can work when starting point is correct
  • Check the ipsilateral neck before and after nailing
  • Address open fractures with antibiotics and debridement principles

High-yield / exam

  • Always look for associated femoral neck fracture
  • IM nail is definitive care for most adult shafts
  • Damage control when physiology forbids a long case
  • Rotation and length errors are preventable
