Study design: Using human cadaver spines, the authors investigated mechanical properties of the interface between titanium mesh cage and vertebra in respect to vertebral bone mineral density.

Objectives: The objective of this study is to examine the effects of the size of the mesh cage and an internal end ring system on interface mechanical properties in reference to vertebral bone mineral density.

Summary of background data: A titanium mesh cage has recently been developed for anterior spinal reconstruction. The cage provides immediate postoperative stability and facilitates bony union with cancellous bone packed in the cage itself. Mechanical properties of the interface between the cage and vertebra, however, are yet to be clarified in osteoporotic spine.

Methods: Twenty-five lumbar vertebrae harvested from embalmed human cadavers (n = 20) were used. The vertebrae wer...
