endplate preparation
Surgical technique of removing cartilaginous endplate while preserving subchondral bone to optimize fusion in interbody procedures.
Full Definition
Endplate preparation is a critical surgical technique in spinal fusion procedures that involves the careful removal of the cartilaginous endplate layer while preserving the underlying subchondral bone architecture. This process exposes bleeding cancellous bone to promote direct bone-to-bone contact and optimize the biological environment for fusion. Proper endplate preparation balances the need for adequate decortication to enhance fusion potential while avoiding excessive bone removal that could lead to cage subsidence or endplate fracture. The technique varies depending on the surgical approach and type of interbody implant used.
Usage
Usage note: Describe extent and technique of preparation; note preservation of subchondral bone.
