Effectiveness & Safety of Mobile Artificial Cervical Vertebrae Replacement

Status Not yet recruiting

Clinical Trial Summary

The research team designed an artificial cervical joint prosthesis suitable for subtotal resection of the lower cervical vertebral body. Previous studies regarding cadaver and animal experiments have found that this artificial joint not only retains the normal range of physiological motion of the joint, but also has good stability. Preliminary studies have shown that the designed joints are sufficiently safe and stable. The titanium materials for joints have been verified for their toxicology in long-term clinical trials and have been monitored under relevant national testing agencies in China.

Clinical Trial Description

Artificial cervical disc technology has achieved certain clinical effects in the treatment of single-segment lesions of the lower cervical spine. However, simple artificial cervical disc replacement is only applicable for single-segment disc herniation, but not for two adjacent cervical segmental lesions, concurrent with vertebral hyperplasia and ossification of the posterior longitudinal ligament in the cervical spine. Traditional vertebral corpectomy and bone graft fusion can reduce the mobility of the cervical spine. Therefore, non-fusion fixation for such diseases has been a key issue to improve the efficacy of surgical treatments. To this end, the research team designed an artificial cervical joint prosthesis suitable for subtotal resection of the lower cervical vertebral body. Previous studies regarding cadaver and animal experiments have found that this artificial joint not only retains the normal range of physiological motion of the joint, but also has good stability. Preliminary studies have shown that the designed joints are sufficiently safe and stable. The titanium materials for joints have been verified for their toxicology in long-term clinical trials and have been monitored under relevant national testing agencies in China. To serve clinical patients faster and ensure that the trial design is safe, this study is designed to observe the effectiveness and safety of mobile artificial cervical vertebrae replacement for patients with cervical spondylosis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
