AXIALIF : TranS1 Presacral Screw
The AXIALIF is a minimally invasive approach which enables the
neurosurgeon or orthopedic spine surgeon the ability to perform a fusion of
L5 and S1, with minimal disruption of tissue.
Below, the approach for the axialif (trans1) is seen, from the side.
The entry point is just lateral to the inferior aspect of the coccyx, and a
path is tunneled behind the peritoneum, until the probe is docked on the
front of the sacrum at the inferior aspect of S1.
Below, a guide pin is seen being placed through the S1 level, into the
l54/s1 disc space.
Next, a working cannula is inserted, as seen below.
A drill is used to enlarge the working canal in the trans1 (axialif
A series of nitenol cutters are used to clean out the disc space, and
reach decorticated bone.
Tissue extractors, or brushes, are used to remove the disc material which
has been loosened by the disc cutters.
A bone graft inserter is used to place bone graft within the prepared
disc space of l5/s1.
After drilling further into the L5 vertebral body, a screw/rod is
inserted into the vertebral bodies of L5 and S1.
The anterior portion of the axialif procedure is complete.
