【 摘 要 】

To evaluate the effect of K-line on posterior single-door decompression with fusion fixation (PFF) and posterior single-door decompression with non-fusion fixation (PNF) for patients with ossification of posterior longitudinal ligament (OPLL). A total of 65 patients with OPLL were analyzed retrospectively. They consisted of 44 patients with positive K-line, designated as the K ( +) group, and 21 patients with negative K-line, designated as K (−). The patients were also divided into a PFF group (38 patients) and a PNF group (27 patients). The Japanese Orthopaedic Association (JOA) score, C2–C7 Cobb angle, improvement rate of JOA score, and complications were calculated and statistically analyzed between the groups. In the K ( +) group, there were no significant differences in the incidence of C5 nerve root palsy and C2–C7 Cobb angle between the two groups of surgical patients, but there were significant differences in the improvement rate of JOA score and the incidence of axial pain. In the K (−) group, there were no significant differences in the incidence of axial pain, the incidence of C5 nerve root palsy, and preoperative C2–C7 Cobb angle between the two groups, but significant differences were observed in the improvement rate of JOA score and C2–C7 Cobb angle at the last follow-up. In the K ( +) group, the improvement rate of JOA score was higher and the incidence of axial pain was lesser in the PNF group than in the PFF group. In the K (−) group, the improvement rate of JOA score was higher in the PFF group than in the PNF group, and there was significant loss of C2–C7 Cobb angle in the PNF group.
