The harvesting of a local bone graft from the lumber vertebral body adjacent to an anterior interbody fusion was suggested, to avoid secondary morbidity associated with iliac bone harvest. Instrumentation using a cannulated core drill was developed and assessed in an anatomic safety study. The biomechanical implications of plug removal were assessed in single vertebra and multisegment models. Plug removal using the tools developed was considered safe. The removal of a cylinder bone plug from the vertebral body affected flexion/compression load significantly. The yield strength of the vertebra could be restored effectively using the filler materials studied.
