Abstract
Artificial disc replacements (ADRs) and total disc replacements (TDRs) include modular components to improve fit. Among other advantages, the use of modular components enable surgeons to “customize” the ADR/TDR at the time of surgery. Modular components of various sizes and shapes can be snapped or otherwise attached to the vertebral surface of ADRs and TDRs. Alternatively, the modular components may be attached using the shape memory technology described in co-pending U.S. Provisional Patent Application Serial No. 60/445,287, incorporated herein by reference.
Claims3
Modular artificial disc replacement apparatus configured for use with an intradiscal device adapted for placement against the endplate of a vertebral body, the apparatus comprising:
- a separate, component having a shape to fill a gap, if any, existing between the intradiscal device and the endplate of a vertebral body once the device is installed.
