The Objective of the Protocol is to Generate Real World Evidence (RWE) Supporting the Safety, Performance, and Health Economics of Using the Regulatory Approved and Commercially Available EARP Interbody System Used During Lumbar Interbody Fusion (LIF) Procedures With the EARP Nerve Cuff Electrode

The goal of the trial is to generate data to support the safety, performance, and cost effectiveness of using the EARP devices during Lumbar Interbody Fusion (LIF) procedures. The primary objectives are: * To evaluate the safety of the EARP surgical technique and devices during LIF surgeries. * To understand the EARP fusion system's ability to achieve fusion and improve disk space over time.
