Intramedullary Fixation

What is intramedullary fixation?

Intramedullary fixation is a surgical technique used to stabilize broken bones by inserting a metal rod, called an intramedullary nail, directly into the marrow canal of the bone. This method provides strong internal support while allowing early mobility and faster recovery.

Intramedullary fixation is commonly used for long bone fractures, including the femur, tibia, humerus, and sometimes forearm bones.

When is intramedullary fixation used?

This technique is typically recommended for:

• Long bone fractures caused by trauma, falls, or sports injuries
• Comminuted fractures, where the bone is broken into multiple pieces
• Pathologic fractures caused by weakened bones from conditions like osteoporosis or cancer
• Nonunions or malunions requiring surgical stabilization
• High-energy trauma, such as car or motorcycle accidents

How intramedullary fixation works

During surgery:

1. The surgeon makes a small incision near the fracture site.
2. A metal rod (nail) is inserted into the marrow canal of the bone.
3. Screws are placed at one or both ends of the rod to lock it in place and stabilize the fracture.
4. The rod supports the bone internally, allowing it to heal in proper alignment.

This minimally invasive approach preserves surrounding muscles and soft tissue while providing strong stabilization.

Benefits of intramedullary fixation

• Strong internal support for fractured bones
• Faster healing and recovery compared to traditional plates and screws
• Minimally invasive technique with smaller incisions
• Early weight-bearing and mobility in many cases
• Reduced risk of bone misalignment during healing

Recovery after intramedullary fixation

Recovery time depends on the type of fracture, the patient’s overall health, and the specific bone involved. Typical recovery guidelines include:

• Hospitalization for 1–3 days for most long bone fractures
• Early mobilization and physical therapy to regain strength
• Gradual return to normal activities and work over several weeks to months
• Follow-up X-rays to monitor bone healing and ensure proper alignment
