Overview
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:
Displaced or unstable shaft fracture
Alignment cannot be reliably held in a cast.
Open fracture
Urgent irrigation, debridement, and stabilization.
Segmental fracture pattern
Two fracture levels are inherently unstable.
Polytrauma
Rapid stabilization aids mobilization and overall care.
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 confirmed on X-ray at follow-up visits. Anterior knee pain after tibial nailing is common and sometimes requires nail removal after healing. Delayed union and malrotation are known complications.

Risks & Why We Still Recommend It
Every operation carries risk. The reason we offer this procedure is that the condition, left untreated, causes a tibia that cannot bear weight and whose malalignment, once set, is hard to correct. That is the trade we are managing — not eliminating risk, but choosing the smaller of two unfavorable trajectories.
The risks we discuss with patients before tibial shaft intramedullary nail include:
- bleeding and infection
- anesthesia risk
- blood clot (DVT/PE)
- compartment syndrome (the tibia is the most common site)
- anterior knee pain at the nail entry
- non-union or delayed union
- mal-union (particularly in proximal- or distal-third patterns)
- hardware irritation
The indication to proceed is a displaced or unstable tibial shaft fracture. Patients who don't need this operation don't get it.
