Long-term loss of intervertebral disc height after posterior cervical surgery for ossification of the posterior longitudinal ligament: a retrospective study with more than 3 years of follow-up
Approximately one-quarter of patients developed significant IDH loss after posterior cervical surgery for OPLL. Larger cranio-cervical extension (C0-2 Cobb), OALL at C5/6, and absence of OPLL at C6 were associated with greater risk. Preoperative sagittal alignment and ossification patterns may help identify patients at risk for postoperative disc degeneration.
