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.
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…
Inclusion Criteria: 1. Male and female patients who are 18-80 years of age; 2. Planned interbody fusion surgery, including at least one level of extreme lateral interbody fusion (XLIF) prior to enrollment in the research at one or two consecutive lumbar levels for degenerative disc disease, including those with up to Grade 2 spondylolisthesis, with one of the following NuVasive, Inc. interbody implants: 1. Coroent® XL PEEK interbody implant; or 2. Modulus® 3D-printed titanium interbody implant; or 3. Cohere® XLIF Porous PEEKTM interbody implant. If a transforaminal lumbar interb…
