Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is to compare the physical capability outcomes of patients who undergo single-level ProDisc-L disc replacement with those of patients who undergo stand-alone, single-level anterior lumbar interbody fusion (ALIF). This study will be the first multi-center clinical study to use clearly measurable outcomes from physical tests to compare the results of lumbar disc arthroplasty with disc fusion.
