Summary

This study is undertaken to evaluate the outcomes of Oblique Lateral Lumbar Interbody Fusion (OLLIF). Specifically, the study seeks to measure outcomes on radiological imaging, outcomes reported by the patients on standardized questionnaires, and complication rates.

Conditions

• Degenerative Disc Disease
• Spondylolisthesis
• Lumbar Disc Herniation

Interventions

Type	Name	Description
PROCEDURE	Oblique Lateral Lumbar Fusion	Oblique lateral lumbar interbody fusion (OLLIF) is a lumbar spinal fusion. OLLIF is performed with the patient in the prone position and employs an oblique lateral approach that enables the instrumentation to pass through Kambin's triangle which is defined as the space between the exiting nerve, the superior border of the caudal vertebra, and the superior articulating process of the inferior facet. This approach may be performed without direct visualization, guided by electrophysiological monitoring and biplanar fluoroscopy. During the approach, a blunt probe is used to make contact with the disc, followed by a series of gentle dilations. Discectomy is performed through a 10-mm access portal. The cage is inserted under continued electrophysiological monitoring and fluoroscopy.
