Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Clinical outcome with regard to oswestry disability index and lumbar fusion rate after implantation of titanium coated PEEK cage and common PEEK cage

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cages made of polyetheretherketone (PEEK) and titanium materials reliably produce successful fusion rates and good clinical outcomes. However, there is a paucity of studies that have assessed the optimal material of cage systems. The primary objective of this study was to compare the Oswestry Disability Index (ODI) after instrumented transforaminal lumbar interbody fusion (TLIF) using either titanium-coated polyetheretherketone (TiPEEK) or common PEEK cages. Secondary objectives were to assess differences in fusion rates and differences in pain and in quality of life between these groups.
