Validation of Impaction Grafting for Single-Level Transforaminal Lumbar Interbody Fusion-Technical Pearls and MicroCT Analysis.

Study Design: Cadaveric study.

Background Context: Transforaminal lumbar interbody fusion (TLIF) represents a well-documented operative surgical technique utilized in the management of lumbar pathology requiring interbody arthrodesis. The microstructural properties of impaction grafting (IG) after TLIF has yet to be reported.
