Orthovita, Inc. (NASDAQ: VITA), an orthobiologics and biosurgery company, is pleased to announce that Dr. Pierce D. Nunley, Director of the Spine Institute of Louisiana, will present his abstract, “A Comparison of Clinical Outcomes and Adjacent Level Fractures in Patients Receiving Vertebroplasty for Osteoporotic Compression Fractures Using CortossTM or PMMA: A Prospective, Randomized Trial,” at the 2009 Annual Meeting of the Congress of Neurological Surgeons (CNS). The presentation will take place in New Orleans on Monday, October 26, 2009, at 3:15 p.m.
The abstract was selected by CNS as a Top Ten Abstract for the meeting’s section on disorders of the spine and peripheral nerves. It is based on clinical data from Orthovita’s prospective, randomized, multi-center study comparing the efficacy of its Cortoss product to polymethylmethacrylate (PMMA) in the treatment of vertebral compression fractures (VCF). Dr. Nunley participated in the study as a clinical investigator.
Key findings from the 256-patient clinical study include the following statistically significant benefits for the Cortoss patient group:
- Early patient outcomes assessed at 3 months: With a Visual Analogue Pain Scale (VAS) score success rate of 86.6%, the Cortoss patient group experienced a statistically significant benefit in pain success over the PMMA group, which had a VAS score success rate of 75.0%.
- Long-term patient outcomes assessed at 24 months: With an Oswestry Disability Index (ODI) function assessment success rate of 96.7%, the Cortoss patient group experienced a statistically significant benefit in function success over the PMMA group, which had an ODI success rate of 88.4%.
In addition, the Cortoss patient group experienced benefits over the PMMA cohort in the following outcomes:
