New clinical data has shown 94% lumbar fusion rate and positive clinical outcomes achieved with the Aspen MIS Fusion System (Lanx). Results were presented by Amir Vokshoor, Institute of Neurosurgical Innovation, Marina del Rey, California, USA, at the Western Neurosurgical Society annual meeting (Colorado Springs, USA, September 7–10).
In the study, 85 patients who underwent lumbar fusion with the Aspen system were evaluated. An independent radiologist used post-operative CT imaging to assess posterior fusion, as well as interbody fusion when applicable, and found it was successfully achieved in 94% of patients. Additionally, pain reduction was evaluated using Visual Analog Scale (VAS) values measured pre-operatively and post-operatively for up to two years, with findings demonstrating a clinically and statistically significant improvement from an average score of 6.5/10 pre-operatively to 2.9/10 within three months following surgery. This level of improvement was maintained throughout the follow-up period.
The Aspen system is currently being used in a wide range of surgical applications including posterior lumbar fusions (PLF) and interbody fusions (PLIF, TLIF, ALIF and Lateral) for the treatment of degenerative disc disease, spondylolisthesis, spinal trauma or spinal tumor.
“These data help substantiate the clinical equivalency of the Aspen system to traditional pedicle screws in promoting fusion, a finding that is widely supported by surgeon experience. The Aspen device was developed to be a minimally invasive alternative to pedicle screws in the appropriate cases, allowing surgeons to best tailor fusion procedures to patients’ needs, and we are encouraged by continued research supporting the positive outcomes achieved with the system,” said Dan Gladney, chief executive officer, Lanx.
