Endoscope-Assisted Anterior Lumbar Interbody Fusion with Computed Tomography-Guided, Image-Navigated Unilateral Cortical Bone Trajectory Screw Fixation in Managing Adjacent Segment Disease in L5/S1: Technical Note.

OBJECTIVE

We sought to describe a novel technique in managing a patient with adjacent segment disease at the L5/S1 level.

METHODS

We performed an endoscope-assisted anterior lumbar interbody fusion with computed tomography-guided, image-navigated unilateral cortical bone trajectory screw fixation to treat L5/S1 intervertebral disk pathology.

RESULTS

Patient was successfully treated by a direct endoscopic decompression through the anterior access, interbody fusion using an anterior lumbar interbody fusion cage, unilateral cortical bone trajectory instrumentation under computed tomography-guided image navigation.

CONCLUSIONS

This minimally invasive technique is effective in terms of decompression and fixation. It could be used as an alternative method to treat patients with L5/S1 adjacent segment disease.
