Degenerative Disc Disease Clinical Trial

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

Clinical Trial Summary

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.

Clinical Trial Description

This study is a prospective, non-concurrent, multicenter study to compare the clinical and radiographic outcomes of smooth PEEK, 3D-printed titanium, and Porous PEEK interbody implants when used with cancellous allograft chips with BMA or cellular allograft in subjects who undergo XLIF surgery at one or two levels. To minimize selection bias, all consecutive patients at a given site who meet eligibility requirements will be asked to consent to participate in the study. These patients will present with degenerative conditions in the lumbar spine that are amenable to surgical treatment and will be screened prior to study enrollment. Once enrolled into the study, subjects will undergo their XLIF operation using one of the 3 previously noted interbody implants based on a non-concurrent enrollment schedule. The bone graft material used inside the interbody implant will be randomly assigned between cancellous allograft chips with BMA or cellular allograft prior to surgery based on surgeon investigators' equipoise for the effectiveness of both bone graft materials. Subjects will be followed for 24 months following surgery to determine the number of study subjects that are solidly fused at or before 24 months postoperatively. ;
