[Research progress of percutaneous 360 degree axial lumbar interbody fusion technique].

OBJECTIVE

To review the feature, biomechanics, and clinical application of percutaneous 360 degree axial lumbar interbody fusion (AxiaLIF) technique.

METHODS

Recent literature on investigation and application of percutaneous 360 degree AxiaLIF technique was reviewed.

RESULTS

Percutaneous 360 degree AxiaLIF technique mainly contained operative approach, axial technique, and posterior fixation. It was obviously different from other lumbar interbody fusion techniques due to its capability of maintaining the integrity of the bilateral facet joints, the anterior/posterior longitudinal ligament, and the annulus fibrosus. Three-dimensional AxiaLIF Rod provided axial support and firmly fixation, thereby relieving stenosis of lumbar intervertebral foramen and restoring the intervertebral disc height and the whole height and physiological curvature of the lumbar spine. The recovery of the intervertebral disc height could restore the folded or crumpled flavum, the posterior longitudinal ligament, and the herniated annulus, resulting in the improvement of stenosis symptoms of nerve root canal or central vertebral canal.

CONCLUSION

Percutaneous 360 degree AxiaLIF technique achieves satisfying therapeutic effects, although it has fairly narrow indication and needs long-term follow-up observation.
