The importance of being able to stay above L3. If that can be done, even H-rods can be a good solution. This is why I think they have largely "solved" T fusions for several decades now. The pedicle screws are just icing on that cake. T fusions, with so little need to preserve the minimal motion there, were low hanging fruit. Now they need to solve L fusions.
