Brief Summary
STUDY OBJECTIVES: Demonstrate equivalent clinical and radiologic outcomes to the "gold standard" (ABG) in a representative clinical model (hindfoot and ankle fusions) STUDY HYPOTHESIS: Augment® Bone Graft is an equivalent bone grafting substitute to autologous bone graft in applications as shown by non-inferiority analysis STUDY RATIONALE: Evaluate a fully synthetic growth-factor enhanced bone graft substitute to facilitate fusion in conditions or injuries requiring bone graft in a representative clinical fusion model and thus the opportunity to provide equivalent union rates as ABG without necessitating an additional invasive procedure to harvest the graft REGULATORY PHASE: Investigational Device Exemption (IDE) for Premarket Approval (PMA) Application as a bone regeneration system, pivotal phase

Outcome Measures
Primary Outcomes (1)
Subjects Fused at 24 Weeks (as Determined by CT Assessment)
An independent radiologist examined CT images for all patients' joints and determined whether or not the joint had at least 50% osseous bridging. If a patient demonstrated all joints having at least 50% osseous bridging, this patient was classified as fused.

Eligibility Criteria
You may qualify if:
- \) Bone defect in the hindfoot or ankle requiring fusion using open surgical technique with supplemental bone graft/substitute, requiring one of the following procedures:
- Ankle joint fusion
- Subtalar fusion
- Calcaneocuboid fusion
- Talonavicular fusion
- Triple arthrodesis (subtalar, talonavicular and calcaneocuboid joints)
- Double fusions (talonavicular and calcaneocuboid joints)
You may not qualify if:
- Previous fusion surgery of the proposed fusion site.
- The patient uses chronic medications known to affect the skeleton (e.g. glucocorticoid usage \> 10mg/day).
- Pregnant or a female intending to become pregnant during this study period.
- Morbidly obese (BMI \> 45 kg/m2)
