A Prospective, 5-Year Global Study on MAST™ Minimally Invasive Fusion Procedures for the Treatment of the Degenerative Lumbar Spine

Medtronic Spinal and Biologics·observational·Posted Dec 1, 2015·Updated Jan 21, 2026

In Brief

An observational study evaluating Minimally invasive lumbar fusion for Intervertebral Disc Degeneration. Completed, enrolled 361 participants across 27 sites in 17 countries.

Detailed Summary

The purpose of this study is * to evaluate the effectiveness of MAST techniques for anterior/lateral and posterior approaches in Degenerative Disc Disease (DDD) patients with spondylolisthesis (≥ grade I). * To assess how single or double level MAST(Minimal Access Spinal Technologies) fusion procedures PLIF (Posterior Lumbar Interbody Fusion), TLIF (Transforaminal Lumbar Interbody Fusion), DLIF (Direct Lateral Interbody Fusion), OLIF (Oblique Lumbar Interbody Fusion), ALIF (Anterior Lumbar Interbody Fusion), or MIDLF (Midline Lumbar Interbody Fusion) are used in surgical practice and to describe long-term safety and effectiveness in a broad patient population of patients with degenerative lumbar disc disease .

Interventions

Minimally invasive lumbar fusiondevice

Patients will receive a single or double level instrumented fusion using a minimally invasive/MAST™ PLIF, TLIF, DLIF, OLIF, ALIF or MIDLF surgical procedure with a posterior fixation. For the use of a posterior fixation system, the CD Horizon™ Spinal System, is mandatory in this study and will be either mini-open and/or percutaneous.
