A Follow-up Study to Evaluate the Efficacy and Safety of Novomax in Posterior Lumbar Interbody Fusion
Study Details
Study Description
Brief Summary
This is a long-term follow-up study for more than 3 years to evaluate the efficacy and safety of bioactive glass-ceramic intervertebral spacer (Novomax) in posterior lumbar interbody fusion.

Detailed Description
During one-level PLIF, bioactive glass-ceramic intervertebral spacer (Novomax) and titanium cage were inserted in the experimental group and control group, respectively. Bone fusion by simple radiography had angular deformity of less than 3 degrees and a potential of less than 3 mm in flexion extension radiographs, and thin-section CT (<2 mm) was used to determine the combination between the vertebral endplate and the autogenous bone or bioactive glass-ceramic intervertebral spacer (Novomax) in the cage without any gaps or the part connected to bony trabecula as fusion, and both groups will be compared.
