To demonstrate equivalent clinical and radiologic outcomes as "gold standard" (Autologous Bone Graft) in a representative clinical model (hindfoot fusions)


Augment™ Injectable is an equivalent bone grafting substitute to autologous bone graft in applications as shown by superiority analysis for safety and non-inferiority analysis for effectiveness


To evaluate a fully synthetic bone graft material 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 Autologous Bone Graft without necessitating an additional invasive procedure to harvest the graft

Condition Intervention Phase
Degenerative Joint Disease
Congenital Deformity
Rheumatoid Arthritis
Device: Augment(tm) Injectable Bone Graft
Procedure: Autologous bone graft

Arms Assigned Interventions
Active Comparator: Autologous bone graft
Standard Rigid Fixation + Autologous bone graft
Procedure: Autologous bone graft
Implantation of up to 9cc of autologous bone graft
Experimental: Augment(tm) Injectable Bone Graft
Standard rigid fixation + Augment(tm) Injectable Bone Graft (beta-TCP/bovine collagen matrix + rhPDGF-BB)
Device: Augment(tm) Injectable Bone Graft

Detailed Description:


Prospective, randomized, controlled, non-inferiority, multi-center trial


Up to 25


201 Subjects (see "Study Population")


Male and female subjects 21 years of age or older requiring a hindfoot fusion procedure involving a bone grafting procedure.


Group I: Standard Rigid Fixation + Autologous Bone Graft Group II: Standard Rigid Fixation + Augment™ Injectable Bone Graft

Subjects will be randomized in a 2:1 ratio (Augment™ Injectable:Autologous Bone Graft).


Investigational device is manually implanted inside and around the fusion space to ensure Augment™ Injectable Bone Graft (beta-TCP/bovine collagen matrix +rhPDGF-BB) or autologous bone graft is contained within the joint space


Twenty-four month follow-up post-surgery


Ages Eligible for Study:   21 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


  • The subject is diagnosed with degenerative joint disease (DJD) affecting the hindfoot due to a congenital or acquired deformity, osteoarthritis, rheumatoid arthritis, post-traumatic arthritis or ankylosing spondylitis of the subtalar, calcaneocuboid, and/or talonavicular joints.
  • The subject requires hindfoot fusion with supplemental bone graft/substitute, requiring one of the following procedures:

    • Subtalar fusion (talocalcaneal)
    • Calcaneocuboid fusion
    • Talonavicular fusion
    • Triple arthrodesis (subtalar, talonavicular and calcaneocuboid joints)
    • Double fusions (any combination of any two of the following: subtalar, talonavicular and calcaneocuboid joints)
  • The fusion site is able to be rigidly stabilized with screw fixation
  • The subject is at least 21 years of age and considered to be skeletally mature.


  • The subject has undergone previous fusion surgery of the proposed site (i.e., revision of failed fusion attempt).
  • The subject has retained hardware spanning the joint(s) intended for fusion.
  • The procedure is anticipated to require use of plate fixation (including claw plates), intramedullary rods (or nails), or more than three (3) screws across the fusion site to achieve rigid fixation.
  • The subject requires a pantalar fusion (i.e. fusion of the ankle plus all hindfoot joints [talonavicular, subtalar, and calcaneocuboid]) or an ankle fusion in combination with any hindfoot fusion.
  • The subject has tested positive or been treated for a malignancy in the past or is suspected of having a malignancy or are currently undergoing radio- or chemotherapy treatment for a malignancy anywhere in the body.
  • The subject uses chronic medications known to affect the skeleton (e.g., glucocorticoid usage >10mg/day).
  • The subject has a diagnosis or history of bi-polar disorder, schizophrenia, suicidal ideation, post traumatic stress disorder, senile dementia or Alzheimer's disease.
  • The subject has an allergy to yeast-derived products.
  • The subject has an allergy to bovine collagen and/or other bovine source medication, supplements or products.
  • The subject is pregnant or a female intending to become pregnant within 12 months of the study procedure.
  • The subject is deemed morbidly obese (BMI >45 kg/m2).
  • The subject refuses to discontinue using tobacco products prior to surgery.
