VERTEBRAL BODY REPLACEMENT AND METHOD FOR SPANNING A SPACE FORMED UPON REMOVAL OF A VERTEBRAL BODY

摘要

A vertebral body replacement includes first and second end plates, and a compliant connector section between the end plates having one or more helical cuts to provide limited compliance between the end plates. The compliant connector section can be provided in a separate spacer that fits between the end plates or directly in one or more of the end plates. The adjoining end plate surfaces, and/or adjoining surfaces of the spacer, include a rotation interlock to inhibit rotational motion between the surfaces and to allow the selection of a modular stacking assembly of the vertebral body replacement to accommodate a wide range of patients.
