Core Tip

Core Tip: This is a cross-sectional study of 80 patients who underwent oblique lateral interbody fusion. The radiographic results were measured using computed tomography while clinical results were assessed using MacNab Scale and cases with unresolved nerve root compression were registered. Indirect decompression is achieved by segment height restoration and the reduction of slipped vertebra. Using multivariate regression modeling it has been evaluated that postoperative spinal canal square is more predictable than the lateral recess depth. Marginal values of the lateral recess depth that can be used for the prediction of unsatisfactory results according to MacNab scale were estimated.
