All trials for Ossification of Posterior Longitudinal Ligament All trials of ACAF surgery All trials of ACCF surgery
Background:The ACAF technology has been in clinical trials for some time. More and more doctors are starting to pay attention to this technology. There are many hospitals in China that have developed this technology. In order to prove that this technology has a significant effect on the treatment of cervical ossification of the posterior longitudinal ligament, we compared the efficacy of traditional ACCF surgery, in order to make the conclusion more true, we decided to carry out multi-center research.
Purpose: The aim of this study is to compare the effectiveness of clinical outcomes between ACAF surgery and Anterior cervical corpectomy decompression and fusion（ACCF）in patients with OPLL and CSS . A study hypothesis is that ACAF surgery outcomes will be equal even better and lower surgical complications which compared to ACCF surgery.
Methods: This study is a multi-center randomized clinical trial with randomized, controlled, multicenter research design. The OPLL patients will be randomly assigned in one of the two treatment groups: ACAF surgery and ACCF surgery. Five outcome measures will be collected pre-operative for baseline, and then at1, 12, 24, 48, 96,240weeks post-operative follow-up visits, including: (1)JOA) .(2)VAS. (3)NURIC Graded .(4)NDI . (5) radiological parameter. After randomization, the ACAF group will receive anterior controllable antedisplacement and fusion and the ACCF group will receive anterior cervical corpectomy decompression and fusion.
Background: Although anterior and posterior decompression surgery are both reported to treat patients with myelopathy caused by OPLL（Posterior longitudinal ligament ossification）. The surgical strategy of the disease is still controversial when the OPLL is multilevel and severe. Novel techniques for better and safer results are required. Dr. Shi recently proposed a new technique as Ossification of anterior decompression surgery, which is also called anterior controllable antedisplacement and fusion (ACAF) , for ossification of the posterior longitudinal ligament (OPLL) with myelopathy. The ACAF technology has been in clinical trials for some time. More and more doctors are starting to pay attention to this technology. There are many hospitals in China that have developed this technology. In order to prove that this technology has a significant effect on the treatment of cervical ossification of the posterior longitudinal ligament, we compared the efficacy of traditional ACCF surgery, in order to make the conclusion more true, we decided to carry out multi-center research.

Methods: This study is a multi-center randomized clinical trial with randomized, controlled, multicenter research design. The OPLL patients will be randomly assigned in one of the two treatment groups: ACAF surgery and ACCF surgery. Five outcome measures will be collected pre-operative for baseline, and then at1, 12, 24, 48, 96,240weeks post-operative follow-up visits, including : (1) Japanese Orthopaedic Association (JOA) scales to assess the spinal cord functions.(2)Visual analogue scale (VAS) to assess pain relief. (3)NURIC Graded to assess walking function.(4) Neck Disabilitv Index(NDI) to assess cervical function . (5) radiological parameters to assess ossification forward distance. And the pre \& postoperative radiological parameters, and surgical complications were also investigated. The investigator performing the outcome measures will be blinded to group assignment, and therefore will not participate in treatment. After randomization, the ACAF group will receive anterior controllable antedisplacement and fusion and the ACCF group will receive anterior cervical corpectomy decompression and fusion.
Data Analysis: T test or wilcoxon rank sum test will be used to examine the differences in the five measures between groups and at the six different time frames with the α level set at 0.05. Chi square test will be used to compare the differences in the surgical complications data over time and between groups.
