Brief summary

Anterior cervical decompression and fusion is the standard procedure for operation of cervical disc herniations. Mobility-preserving Full-Endoscopic Cervical Posterior discectomy is the most common alternative in the case of soft localization of the pathology. Endoscopic techniques are considered standard in many areas, since they may offer advantages in surgical technique and rehabilitation. These days, all disc herniations can be operated in full-endoscopic technique. With the full-endoscopic posterior cervical discectomy a procedures is available for cervical disc operations.

Detailed description

Investigators conducted a differential, randomized, 1:1, double-blind clinical control trial to compare the clinical effect, safety and feasibility of Full-Endoscopic Cervical Posterior discectomy and Anterior cervical decompression and fusion. The study was conducted in three centers at the same time, including the Second Affiliated Hospital of Zhejiang University Medical College, Zhejiang Provincial People's Hospital and Ningbo University Medical College Affiliated Hospital. This study is expected to include 308 patients with single level soft cervical disc herniation.Participants were randomly assigned to different groups for corresponding surgical intervention after complete preoperative evaluation.Participants received a standard 5-year follow-up procedure
