Abstract
Objective To compare the surgical outcomes of patients with ossification of the posterior longitudinal liga-ment (OPLL) with negative K-line in the neck neutral position but positive K-line in extension radiograph with pa-tients with OPLL with positive K-line in neutral radiograph. Methods The 73 patients with OPLL were treated by u-sing single-door laminoplasty. There were 41 patients with positive K-line in neutral radiograph (standard positive K-line group) and 32 patients with negative K-line in the neck neutral position but positive K-line in extension radio-graph (extension positive K-line group). The clinical function was evaluated by using the JOA score and the recovery rate of neurological function was calculated. Results All of the 73 patients were followed up for 18～36 (23.8±5.5) months. At final follow-up, the JOA score was improved from preoperative 9～13 (11.4±1.7) points to 11～17 (14.8±3.6) (P＜0.001) in standard positive K-line group, the score was improved from preoperative 8～12 (10.3±1.6) to 11～16 (13.4±2.8) points (P＜0.001) in extension positive K-line group; the JOA recovery rate was 46.7% ～85.1% (60.8%±18.6%) in standard positive K-line group and 36.2% ～ 76.3% (49.1%±19.7%) in extension positive K-line group. There was no statistical difference between two groups in term of JOA score at final follow-up (P=0.087), but there was statistical difference between two groups in term of JOA recovery rate (P=0.011). Conclusions Laminoplasty is a safe and effective treatment procedure for OPLL with negative K-line in the neck neutral position but positive K-line in extension radiograph. However, the improvement of postopera-tive neurological function in patients with standard positive K-line OPLL is better than that of patients with negative K-line in the neck neutral position but positive K-line in extension radiograph.关键词
