Assessment of nanOss Bioactive 3D in the Posterolateral Spine

Status Completed

Clinical Trial Summary

Spine fusion is one of the most common procedures performed in spinal surgery. Several surgical techniques can achieve a solid union, but the intertransverse posterolateral fusion (PLF) is the most widely used. However, complications can develop when the bone graft material used is insufficient to achieve the desired fusion. With its unique properties, nanOss Bioactive 3D can be mixed with bone marrow aspirate (BMA) and autograft bone to obtain new bone growth during the healing process.

nanOss Bioactive 3D is approved for use in the U.S., however, additional information is useful to assess its efficacy in the posterolateral spine. The purpose of this study is to assess fusion results in the posterolateral spine using nanOss Bioactive 3D mixed with autograft bone and BMA. It is hypothesized that the use of nanOss Bioactive 3D will result in fusion at 12 months, with CT evidence of bridging trabecular bone, less than 3mm of translational motion, and less than 5 degrees of angular motion.

Clinical Trial Description

The post market clinical investigation is designed to assess instrumented PLF using nanOss Bioactive 3D bone void filler with autograft bone and bone marrow aspirate in patients with symptomatic spinal stenosis secondary to degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis at one or two adjacent levels from L2-S1 characterized by the inclusion and exclusion criteria.

Patients will be evaluated at Preop, discharge, 6 and 12 months. X-rays will be obtained at each visit; Additionally, a CT scan will be performed at the 12 month postoperative visit to assess fusion status. ;
