Lumbar Implants & Fusion:
Major Surgeries for the Low Back
Anterior Lumbar Interbody Fusion - ALIF -
with Femoral Ring Allograft
After removing most of the disk, the surgeon can spread open the collapsed disk space and then place a graft. These grafts sliced from a femur leg bone of a cadaver donor and are machined to an optimum wedge shape. A femoral ring allograft also allows for the placement of bone fusion promoting proteins in the central space of the ring graft. FRA System – illustration with permission of AO Synthes.
