Modified laminoplasty versus laminectomy with fusion in different K-line status among patients with high occupation rate of cervical ossification of longitudinal ligament

This was the first prospective cohort to compare mLP and LF for HOR-cOPLL. Both the mLP and LF groups demonstrated significant neurological recovery and similar preservation of cervical curvature over a 2-year period, regardless of K-line status. Notably, mLP offers advantages in surgical efficiency and reduced blood loss, suggesting its potential as a less invasive alternative to LF.
