AxiaLIF® - Axial Lumbar Interbody Fusion

AxiaLIF® - Axial Lumbar Interbody Fusion: Overview

Overview

 In this minimally_invase procedure, performed under general anesthesia, portions of the diseased or damaged disc in the lumbar spine are removed and a device is implanted to secure one or more vertebrae to the sacrum. It is typically used to treat back pain caused by a degenerative disc between the lowest lumbat vertebra (L5) and the top of the sacrum (S1)

Preparation

The patient is anesthetised and placed in a face down position to allow access to the lower back. The area is cleaned and sterilised.

1. Creating the Incision

The surgeon creates a tiny incision next to the coccyx (the tailbone). The procedure will be performed through this incision, avoiding the need to cut through any major muscles, tendons or nerves.

 2. Accessing the Damaged Disc

Using fluoroscopic guidance, the pfysician pushes a series of dilation tubes along the tailbone and the front of the sacrum. The physician inserts a drill through the tube and uses it to create a channel through the upper portion of the sacrum, allowing access to the centre of the damaged disc.

3. Cleaning the Damaged Disc

Tools are pushed into the disc and the centre of the disc is broken apart and removed through the dilation tube. The hollow centre of the disc is then filled with bown growth material.

4. Stabilising the spine

The physician pushed the drill back through the dilation tube and creates a channel into the vertebra above the damaged disc. The 3D Axial Rod ™ is threaded into the vertebra. As the rod is twisted, it lifts the vertebra, restoring any height that was lost because of the collapsed disc.

Further Stabilisation

After the rod is implanted, the physician may choose to further stabilise the spine by implanting screws through the facet joints or the pedicles of the affected vertebra in a minimally-invasive fashion

End of Procedure

The instruments are removed and the incision is closed with sutures. Many patients can leave hospital the next day

5. After Care

During the next few months, the bone growth material will cause the vertebra and disc area to fuse to the sacrum. Patients should avoid lifting, bending and athletic activity for 6 to 12 weeks after the procedure
