Comparison Between Insertion of Bilateral Straight Cages Versus Unilateral Banana Cage in Lumbar Fusion Surgery
Sponsor: Assiut University
Summary
\- To compare the clinical outcomes of bilateral straight cages and unilateral banana cage insertion in lumbar interbody fusion surgery, assess radiological outcomes, including intervertebral disc height, lumbar lordosis angle, and radiographic evidence of fusion, evaluate the rate of complications, such as cage migration, subsidence, pseudoarthrosis, and adjacent segment degeneration and analyze differences in operative time, blood loss, and length of hospital stay between the two techniques

cages in lumbar fusion surgery
A critical factor in TLIF procedures is the type and positioning of the interbody cage. Traditionally, bilateral straight cages have been inserted to promote symmetrical load sharing and increase the surface area for fusion. This technique aims to ensure even support of the anterior column and reduce the risk of cage subsidence or pseudarthrosis. On the other hand, unilateral insertion of banana-shaped cages has been introduced as a potentially less invasive alternative that simplifies the procedure while still achieving adequate segmental stability and fusion
