Tibial shaft intramedullary nail

Intramedullary nail fixation of a tibial shaft fracture through small incisions to restore length, alignment, and allow early weight-bearing.

Overview

Front view of the knee showing the femur, tibia, patella, cruciate and collateral ligaments, and the medial and lateral menisci.
Knee anatomy. The knee is the meeting point of the thigh bone (femur), shin bone (tibia), and kneecap (patella). Four ligaments hold it together — the ACL and PCL inside the joint and the MCL and LCL on the sides — and two C-shaped menisci cushion the joint surfaces.

The tibia is the main weight-bearing bone of the lower leg. Shaft fractures often result from high-energy mechanisms such as falls or sports injuries. Because the tibia lies just under the skin along its front surface, open fractures are common.

Intramedullary nailing is the workhorse treatment for displaced tibial shaft fractures. It restores length and alignment through small incisions without directly exposing the fracture, which preserves the healing biology.

Why it's done

Tibial shaft intramedullary nail is typically considered when imaging and the clinical picture together indicate that the fracture will not reliably heal or function without surgical stabilization. Common indications include:

  1. Displaced or unstable shaft fracture

    Alignment cannot be reliably held in a cast.

  2. Open fracture

    Urgent irrigation, debridement, and stabilization.

  3. Segmental fracture pattern

    Two fracture levels are inherently unstable.

  4. Polytrauma

    Rapid stabilization aids mobilization and overall care.

  5. Nonunion from prior non-operative care

    Nailing plus bone grafting salvages most cases.

How it works

Through a small incision at the front of the knee (either patellar tendon-splitting, medial parapatellar, or suprapatellar), a guidewire is passed down the medullary canal of the tibia under fluoroscopic guidance. The canal is progressively reamed to accept a solid or cannulated nail.

Interlocking screws above and below the fracture control rotation and length. Associated fibular fractures rarely need fixation. Fluoroscopy confirms final alignment, rotation, and nail position.

Recovery

Most isolated tibial shaft fractures allow weight-bearing as tolerated shortly after surgery, particularly with modern locked nails. Early knee and ankle motion begins immediately. Union is typically seen by three to six months. Anterior knee pain after tibial nailing is common and sometimes requires nail removal after healing. Delayed union and malrotation are known complications.
