Prevention of lower instrumented vertebra pedicle screw failure in multilevel constructs for adult spinal deformity surgery using hybrid hook-screw constructs.

Summary: Imagine your spine needs surgery to help you stand up straight. Doctors often use metal screws and rods to hold the bones together. Sometimes, the bottom screws break or pull out of the bone. To stop this, doctors tried a new mix of hooks and screws. They looked at 53 patients to see if it worked.

The good news? The new hook-screw mix stopped the screws from breaking! But there was a catch. While the screws stayed safe, the tough bands of tissue (ligaments) holding the spine together were more likely to tear. In the end, the total number of problems was about the same for both methods. Doctors need to pick the right patients carefully when using this new method.
