The Acron TLIF System is the result of several years of research and development partnership with Orthopedics and Neurosurgeons from Austria. The research program was focused on developing an Interbody system that maximized the chance of a solid spinal fusion while minimizing the risks.

Method:

• Indications for surgery included DDD, spinal stenosis, Spondylolisthesis, degenerative lumbar scoliosis and Post Nucleotomy Syndrome..
• 110 patients have been treated representing a total of 157 segments.
• 75 mono segmental, 23 two level and 12 three level fusions.
• Scoring included VAS, neurological and functional status.
• X-ray was done intraop and 3 days and 3 months postop.

Results:

• OP time and blood loss did not exceed usual surgery.
• VAS improved in 92 patients, 14 patients showed transitional sensible disturbance and 4 motor weakness that restored in 2 patients completely.
• 2 cages showed loosening due in the early learning curve.
• Cage positioning transversely in the anterior part with restoration of disc height up to 40% could be seen in all cases.
• Postoperative lordosis increased up to 45%

Conclusions:

The ACRON cage technique can be a missing link in lumbar fusion surgery.
