Assess stability and neurology with TLICS; Load Sharing Classification (McCormack) predicts need for anterior support. High load‑sharing score (≥7) → consider anterior column reconstruction with corpectomy/cage in addition to posterior fixation. Posterior pedicle screw constructs (short vs long segment) are standard; add intermediate screws at the fractured level to improve stability. Canal compromise alone is not an absolute indication for laminectomy—retropulsed fragments resorb over time if PLC intact and no neuro deficit. Monitor for kyphosis progression and failure of short constructs in highly comminuted fractures.
