The tibia and fibula are the two long bones of the lower leg between knee and ankle. The tibia (shinbone) is larger, medial and weight-bearing, forming joints with the femur and ankle. The fibula is thinner, lateral, provides muscle attachment and ankle stability, and bears little weight. They connect via an interosseous membrane and tibiofibular joints; both can be injured.

Treat tibia and fibula pain by resting and avoiding weight-bearing, applying ice 15–20 minutes every 2–3 hours, using compression and elevation, and taking paracetamol or NSAIDs for pain. Use a supportive splint or boot if needed. Seek medical review for severe swelling, deformity, numbness, worsening pain, or no improvement—imaging, physiotherapy, or surgery may be required. Gradually resume activity per clinician guidance.

Yes — a foot MRI is noninvasive and you can usually walk and resume normal activity afterward. Exceptions: if you had sedation, a local anesthetic, or an injection (arthrogram/contrast), you may be advised to avoid weight-bearing or driving until cleared. Follow any technologist/radiologist instructions and contact them if you experience an adverse reaction to contrast.

A broken tibia and fibula can be serious. These weight-bearing bone fractures may be simple or complex; displaced or open fractures risk damage to vessels, nerves, infection, compartment syndrome, and long-term deformity or nonunion. Treatment ranges from casting to urgent surgery (rods, plates) and prolonged rehabilitation. Seek prompt medical evaluation and follow-up to reduce complications and restore function.

Common problems affecting the tibia include traumatic fractures (tibial shaft and plateau), stress fractures and shin splints (medial tibial stress syndrome), compartment syndrome, infections such as osteomyelitis, growth‑plate/apophysitis conditions like Osgood‑Schlatter disease, bone tumors or metastases, and complications such as nonunion, malunion, and chronic post‑injury pain.

Recovery varies by fracture severity: isolated fibula fractures often heal in about 6 to 8 weeks; tibial shaft fractures usually need 3 to 6 months for bone union, with more severe injuries sometimes taking 6 to 12 months. When both bones are broken, healing typically follows the tibial timeline. Age, health, smoking and weight‑bearing rules all affect progress; follow‑up X‑rays guide rehab.
