Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy of Biphasic Calcium Phosphate Ceramic With a Needle-shaped Surface Topography Versus Autograft in Instrumented Posterolateral Spinal Fusion: A Randomized Trial.
A multicenter randomized controlled noninferiority trial with intrapatient comparisons. ⋯ This clinical trial demonstrates noninferiority and indicates superiority of MagnetOs Granules as a standalone ceramic when compared to autograft for posterolateral spinal fusion. These results challange the belief that autologous bone is the most optimal graft material.

Multicenter Study
Imaging Characteristics of Non-Rheumatoid Arthritis Patients With Retro-Odontoid Pseudotumor: A Multicenter Case-Control Study.
Multicenter case-control study. ⋯ The development of ROP was associated with degeneration of facet joints and intervertebral disks in the middle and lower cervical spine. Our findings suggest that decreased mobility of the middle and lower cervical spine may cause instability in the upper cervical spine, leading to the formation of ROP.
