The Wilhelm Tell technique for anterior lumbar interbody fusion

Technical note

Restricted access

✓ Experience indicates that stand-alone cages may lack the necessary stability to secure highly unstable motion segments at the lumbosacral junction.

The authors have designed a special carbon fiber composite interbody cage that allows additional screw placement in anterior lumbar interbody fusion procedures performed at the lumbosacral junction.
