Long-term Safety and Effectiveness of AUGMENT® Bone Graft Compared to Autologous Bone Graft

The objective of this long-term study is to evaluate the long term effectiveness and safety of AUGMENT® Bone Graft vs. autologous bone graft. The study involves evaluation of subjects originally treated under Protocol BMTI-2006-01. Subjects will be asked to consent and return to provide long-term follow-up data at or after 60 months (5 years) have elapsed since their original surgery as a subject in protocol BMTI-2006-01. STUDY HYPOTHESIS: The effectiveness and safety profile for AUGMENT® Bone Graft is maintained and remains comparable to that of autologous bone graft over long-term subject follow-up. REGULATORY PHASE: Post-approval study
