Okay, so you broke your tibia. Your shin bone. It’s one of the most common long-bone fractures, but that doesn't make it any less awful. After the initial shock wears off, your surgeon starts talking about the fix. Most of the time, this means surgery to place a long metal rod, or "nail," down the hollow center of the bone. This acts as an internal splint, holding everything in place so it can heal. Simple enough. But here’s a detail you probably haven't thought about: how does the surgeon get that rod in there? The entry point matters. A lot. And a newer technique called Suprapatellar Nailing is changing the game for the better.
