Tibia & Plateau Fractures
The tibia, or shinbone, is the primary weight-bearing bone of the lower leg, and fractures can significantly limit walking and function. The two main types are tibial shaft fractures and tibial plateau fractures.
Shaft fractures occur in the middle of the bone and are usually caused by high-energy trauma such as car accidents, sports injuries, or major falls, though stress fractures can also develop in overtrained athletes. Tibial plateau fractures involve the top of the bone at the knee joint and often result from combined forces like direct impact or twisting, commonly seen in pedestrian accidents, skiing injuries, or falls in older adults.
Plateau fractures are especially serious because they disrupt the joint surface, where even small misalignments can affect long-term knee function. Symptoms include severe pain, swelling, deformity, and inability to bear weight. In high-energy shaft fractures, compartment syndrome is a critical complication to monitor. CT imaging is often used to better evaluate complex fracture patterns, particularly in plateau injuries.
Treatment
For tibial shaft fractures, my approach depends on whether the fracture is minimally displaced. If it is, I can treat it without surgery using a cast or brace, allowing the bone to heal while keeping motion protected. However, for displaced or unstable shaft fractures, surgery with an intramedullary nail is my gold standard. The nail is inserted down the center of the bone and allows my patients to start moving the knee and bearing weight much sooner than they could with casting, which leads to better functional outcomes.
Tibial plateau fractures require a different strategy entirely. Nondisplaced plateau fractures can heal well with protected weight-bearing and no surgery, but displaced fractures need surgery to restore the flat joint surface. I use a technique called ORIF, open reduction and internal fixation, with plates and screws to carefully rebuild the plateau. In some cases, especially with more severe fractures, I place both medial and lateral plates to support the joint adequately.
For severely comminuted or open fractures, I sometimes use an external fixator initially while soft tissue wounds heal, then perform the definitive ORIF later once it’s safe—a staged approach that protects both bone and surrounding tissues. I also evaluate every plateau fracture for associated knee ligament injuries, particularly ACL and PCL tears, and meniscus tears. When I find these injuries, I address them during or shortly after fracture fixation when possible. For compartment syndrome, if I suspect it, I perform emergency fasciotomy to relieve the pressure and prevent permanent tissue damage.
Recovery Timeline
Patients with a tibial shaft fracture typically begin partial weight-bearing during this period. Patients with a tibial plateau fracture must maintain strict non-weight-bearing to protect the bone while it heals around plates and screws.
This is the general milestone for progressing to full weight-bearing (shaft fractures) or beginning to walk (plateau fractures).
Most patients with a tibial shaft fracture can expect to return to sports and other demanding physical activities.

Common Tibia & Plateau Fractures Questions
Injury Information
A: Yes, if ignored. Stress fractures start as incomplete cracks from repetitive loading and can progress to a complete break if training continues. I treat stress fractures with rest, activity modification, and sometimes bracing or casting. Most heal well with conservative care if caught early.
A: Open fractures require urgent care, antibiotics, and often an external fixator first to stabilize the bone while wounds heal and infection risk drops. Once the soft tissue is ready, I perform definitive ORIF. Open fractures carry higher infection and nonunion risk, so the approach is more cautious.
A: Compartment syndrome is an emergency. Watch for pain that seems out of proportion to your injury, severe swelling that feels tense and wood-like, numbness or tingling, and weakness. If you notice these within hours of your injury, go to the emergency room immediately. Early fasciotomy can prevent permanent disability.
A: Yes, it’s common. High-energy trauma that breaks the tibia often damages the knee ligaments and cartilage at the same time. Generally, we fix meniscus tears when we see them at the time of surgery. ACL tears, on the other hand, are not amenable to treatment at the same time as a plateau, in most cases. We often have to return to the operating room after the fracture has completely healed to do an ACL reconstruction.
A: CT imaging shows me the exact orientation and number of bone fragments, the degree of displacement, and whether the joint surface is depressed or split. This information is critical for deciding whether to operate and how to reconstruct the fracture. Plain X-rays alone often miss important details.
A: A shaft fracture breaks the middle section of the shinbone, while a plateau fracture involves the top of the tibia where it forms the knee joint. Plateau fractures are intra-articular, meaning the break enters the joint space itself, which is why they need more careful surgical repair to prevent arthritis.
Surgery Information
Post-Op Recovery
A: Not always. Most of my patients do well with hardware left in place permanently. Removal is only considered if the hardware is irritating soft tissue, if there’s infection, or if the patient strongly prefers it. Removal requires another operation and is not routinely recommended.
A: No, but the risk is real. About twenty to forty-four percent of patients develop radiographic signs of arthritis over ten years, but only a small percentage need surgery for it. Factors like the severity of cartilage damage, your age, and meniscus status influence your risk. I discuss these with you specifically.
A: After intramedullary nailing for shaft fractures, most athletes return to sports in four to six months. After plateau fracture repair, the timeline is longer, usually six to twelve months or more, because the cartilage injury limits impact tolerance. I progress you through a structured program before full return.
A: It varies. Desk work might be possible in four to six weeks with elevation and ice. Jobs requiring walking or standing take three to four months after surgery. Heavy labor or jobs with fall risk may take six months or longer. I base this on your fracture type, your job demands, and your healing progress.
A: That depends on which leg is injured and your pain level. For a left leg fracture and automatic transmission, you may drive once you’re off strong pain medications and can perform an emergency stop safely. For a right leg or manual transmission, I wait longer. Always ask your surgeon before getting behind the wheel.
A: The reduction I create during surgery needs time to heal and integrate with the bone underneath. Bearing weight too early can displace the fracture or compress the joint unevenly, leading to poor healing and arthritis. Strict non-weight-bearing for ten to twelve weeks gives the bone the best chance to heal properly.
