Dynamic Stabilization Adjacent to Fusion versus Posterior Lumbar Interbody Fusion for the Treatment of Lumbar Degenerative Disease: A Meta-Analysis

Figure 1

Lateral X-ray of lumbar spine showing (a) PLIF, Pedicle screws were inserted bilaterally at L3–L5 for internal fixation. Interlaminar fenestration or total laminectomy was performed bilaterally at L4/5 for decompression. Interlaminar fenestration was performed bilaterally for decompression at L3/4, with preservation of the lateral 1/2 of the facet joint; (b) hybrid stabilization (Coflex+PLIF), the same procedures were performed to expose the target area and to manipulate the segments at L4–S1 as PLIF. Coflex was inserted to L3/4 with interlaminar fenestration for decompression.
