4. Lumbosacral TLIF but not ALIF increases proximal junction motion in long-segment constructs
Proximal junctional kyphosis and lumbosacral (LS) pseudoarthrosis/instrumentation failure are relatively common complications following long instrumentation constructs to the sacrum. Methods to improve fusion rates and decrease instrumentation failure include LS anterior column support (ALIF or TLIF), iliac screw fixation, and accessory rods. The impact of these lumbosacral augmentation strategies on the proximal junction is not clear.
