Official title

A Prospective Multicenter Study Evaluating the Effect of Implant Material and/or Surface Structure on Progression of Fusion in XLIF® Surgery

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study is being conducted to evaluate the clinical and radiographic outcomes of three different interbody implant types when used with cancellous allograft chips with BMA or cellular allograft in patients undergoing XLIF surgery. The study will evaluate success by comparing the rate of fusion, complications profile, and any relationships between clinical outcomes (pain and function) and radiographic outcomes (fusion rate) between the three implant groups.
