In a recent study published in the International Journal of Spine Surgery, researchers compared the outcomes of posterolateral fusion outcomes and posterior interbody fusion outcomes in patients treated for degenerative lumbar spine disorders. The study included 148 patients undergoing posterior interbody fusion and 159 patients undergoing posterolateral fusion.
The study found:
• The posterior interbody fusion patients showed a lower rate of nonunion
• The posterior interbody fusion patients showed a higher disc height
• The posterior interbody fusion patients showed a lower residual rate of slippage
• Segmental and total lumber lordosis was similar in posterior interbody fusion patients and posterolateral fusion patients
The study suggests that posterior interbody fusion has a higher rate of fusion and deformity correction than posterolateral fusion, but further evidence is needed to fully support this conclusion.
