interbody height restoration
Surgical goal of restoring normal disc space height through interbody cage placement.
Full Definition
Interbody height restoration refers to the surgical objective of reestablishing normal anatomical disc space height that has been lost due to degenerative changes, trauma, or other pathological processes. This is typically achieved through placement of appropriately sized interbody cages or spacers during fusion procedures. Proper height restoration is crucial for indirect decompression of neural structures, restoration of normal spinal alignment, and optimization of fusion environment. Inadequate or excessive height restoration can lead to complications including subsidence, neural injury, or nonunion.
Usage
Usage note: Quantify height gain when possible in operative documentation.
