Expandable Cages for Lumbar Spinal Deformity

Michael Y. Wang

Research output: Chapter in Book/Report/Conference proceedingChapter


Interbody fusion has particular advantages in the setting of adult spinal deformity (ASD). Compared to an intertransverse posterolateral fusion, interbody fusion (1) has a more robust fusion rate due to the improved local vascularity and load sharing present at the endplates, (2) permits anterior release and height restoration for correction of the deformity in the coronal and sagittal planes, (3) allows for bilateral indirect decompression of the neural foramina by restoring interbody height, and (4) in select cases can assist in vertebral de-rotation in the axial plane. These advantages with interbody fusion have led to a plethora of techniques for approaching the disc space, preparing the graft recipient site, and interbody spacer placement.
