This prospective registry was designed as an observational study to ascertain how commercially available NanoBone Bone Graft is being used by surgeons performing spinal fusion as well as determining relevant patient outcomes.


This multicenter prospective patient registry was developed with the aim of documenting how spine and neurosurgeons are utilizing the NanoBone products along with relevant patient outcomes. These outcomes include radiographic measures such as fusion outcome, instrumentation integrity, and clinical outcomes (symptom and function improvement) based on investigator and patient-based outcome assessments.

The primary objective of this study is to document and analyze the use of NanoBone products in spine fusion surgery (as a stand-alone bone graft, or in combination with local bone only, no other BGS or biologic product used) and determine both radiographic success and clinical outcomes. All product related adverse events will be documented, tabulated, and summarized.
