Summary

The purpose of this study is to compare the efficacy, safety and imaging outcomes between Anterior Controllable Antedisplacement and Fusion (ACAF) and Laminoplasty in the treatment of severe ossification of cervical posterior longitudinal ligament.

Detailed Description

This is a national, multicenter, prospective, randomized controlled trial to compare the safety and efficacy of ACAF and posterior laminoplasty in the treatment of severe ossification of cervical posterior longitudinal ligament. In this study, 164 adult patients aged 18-70 with severe copll were randomly assigned to the experimental group (using ACAF) and the control group (using lamp) according to the ratio of 1:1. The patients were followed up for 2 years.
