Abstract

Objective: This technical note describes a simple, easily reproducible, and economical technique for securing an L5 cage after an anterior corpectomy. According to biomechanical and anatomical characteristics of the lumbosacral level, cage dislodgement after an L5 corpectomy is a challenging complication. Methods: Based on a case report, the operative technique described consists of introducing two small screws in the superior plate of S1 avoiding an anterior displacement of the cage. Results: These screws favor an adequate location of the cage, diminishing pseudoarthrosis, and vascular or abdominal injuries secondary to the cage dislodgement. Conclusion: We suggest keeping in mind this technique in cases with an increased risk of cage displacement, or reoperations, which patients have an anatomical impossibility to secure the cage with an anterior plate. It could be a helpful resource in these cases.
