A muti-center study to compare the safety and efficacy of anterior cervical discectomy and fusion, cervical artificial disc replacement and hybrid surgery for bi-level cervical spondylosis.
Patients with bi-level cervical spondylosis undergoing anterior cervical discectomy and fusion, cervical artificial disc replacement and hybrid surgery in the muti-center hospital were retrospectively reviewed.The safety and efficacy were evaluated based on scores of the Neck Disability Index (NDI), visual analog scale (VAS), and Japanese Orthopedic Association (JOA) and the range of motion of both operative segments and adjacent segments,not only in the preoperative,but also in the 5 days,6 months,12 months and the 5 years after surgery.
142 studies on the registry are indexed under Spondylosis; 41 are open to participants now.
This study's planned enrollment of 198 is above the median of 100 across 36 observational studies indexed under Spondylosis.
