What this trial studies

This study aims to compare the effectiveness and safety of a novel surgical monitoring technique using the Endoscopic Assisted Retropsoas (EARP) Nerve Cuff Electrode and Retractor against standard nerve monitoring tools during Transforaminal Lumbar Interbody Fusion (TLIF) surgery. The study will assess how well these devices monitor nerve root function and reduce the risk of nerve damage during surgery. By utilizing both traditional and new monitoring methods, the research seeks to improve surgical outcomes and patient safety.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled to undergo TLIF surgery between the L2 and S1 vertebrae.

Not a fit: Patients requiring TLIF surgery only at the L5-S1 level or those with acute lumbar spine trauma may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the safety and effectiveness of TLIF surgeries, potentially reducing nerve damage and improving recovery outcomes for patients.

How similar studies have performed: While the approach of using nerve cuff electrodes is innovative, similar studies have shown varying degrees of success in improving nerve monitoring during spinal surgeries.
