Placement of Triangular Titanium Implants Suprajacent to Pelvic Fixation Screws Reduces Pelvic Fixation Failure in Multilevel Spinal Fusion: Results of a Randomized Controlled Trial.
The Journal of bone and joint surgery. American volume·July 16, 2026·PMID 42462059
Why it mattersPelvic fixation failure is a common and morbid complication in long-segment adult deformity fusions. This Level I evidence demonstrates that adding TTI suprajacent to S2AI screws can meaningfully reduce mechanical failure at the lumbosacral junction, offering a straightforward surgical adjunct to improve construct durability.
