Popis: In our department, from July 2011 to July 2016, we treated 12 severe cervical posterior longitudinal ligament (8 males and 4 females; mean age 45.2 years) via an total posterior laminoplasty. We followed up all the patients for 16–54 months (mean 32 months). The mean time of operation was 90 min (range: 70–140), and the mean blood loss was 200 ml. The cervical curvature index (mean ± standard deviation) declined from 10.12 ± 11.58 to 8.49 ± 11.68. Of the 12 patients with Japanese Orthopedic Association (JOA) score 8.4 ± 1.5. Two improved to 13.3, three improved to 12.5, three improved to 13, another improved to 13.9. In the follow-up period, we couldn't find any loosening or breakage of the internal implants. Consequently, we could conclude that, although this is dangerous, the posterior laminoplasty alone is safe and effective for treating severe cervical posterior longitudinal ligament. The safety of surgery and clinical efficacy in the follow-up period support this surgical procedure.
