Why is intramedullary nail used in fracture fixation surgery?

The surgeon places the nail through the marrow canal of a suitable long bone and uses locking screws to control rotation and shortening. Because the support follows the bone's central axis, forces can be shared through the limb rather than concentrated only on a plate at the surface. This can provide stability for a fracture pattern that is appropriate for nailing, while leaving the surrounding soft tissues less disturbed than some other approaches.

Not every fracture is suitable. The decision depends on the bone involved, fracture location and shape, skin and soft-tissue condition, other injuries, and your overall health.

Tell the team about medicines, smoking or vaping, previous operations, and any numbness or circulation problems. After fixation, follow the specified weight-bearing limit even if pain improves quickly. Keep dressings and incisions as instructed, attend imaging and review appointments, and complete physiotherapy focused on safe movement, strength, and joint flexibility.

Report worsening pain, increasing swelling, wound drainage, fever, new numbness, pale or cold fingers or toes, or difficulty moving the limb. Seek urgent care for severe pain with a tight swollen limb, sudden breathlessness, chest pain, or fainting. A fall or new injury after fixation should be assessed if it changes pain, alignment, or the ability to bear weight.

Ask why a nail suits your fracture, where the locking screws will sit, how much weight you may put through the limb, what imaging will show healing, and whether any later procedure is being considered.
