Autograft – Gold Standard ?
• Autograft is the current ‘gold
standard’, particularly iliac crest
graft, due to its mechanical and
biological properties
• But if we only need the biologic
stimulation, is it worth it?
• What are the known risks & costs
of graft harvest?

Bone Grafting Disadvantages
Bone grafting has been associated with the following clinical complications:
Abscess
Fracture
Neuroma
Donor Site Pain
Gluteal Gait
Paresthesia
Blood Loss
Hematoma
Scarring
Bone Spur
Hemorrhage
Sensory Loss
Dehiscence
Hernia
Seroma

Is There a Safer Alternative to BG?
Dimitriou ( 2011) :
• Meta analysis: RIA and ICBG
• 92 articles / 6682 patients in database
 RIA complication rate = 6%
 ICBG complication rate = 19.4%

Continual Improvement…
When we have a problem:
Identify a need :
We need an alternative to autograft
Innovate to develop a solution:
Meets the unique needs of foot and ankle
Prove the solution with:
Clinical trials
Record of safety

Angiogenesis
PDGF: 3 Mechanisms
• Formation of new blood vessels from pre-existing vessels
• Regulated by expression of VEGF (a molecule closely
related in morphology to PDGF)
• PDGF Upregulates VEGF1
• Criticality of angiogenesis to healing process
• Deliver nutrients/oxygen
• Eliminate waste
• Permit physical ingress of cells
• Permit ingress of factors to direct healing

AUGMENT® Bone Graft Trial Overall Summary
• Largest, most rigorously controlled
and performed Level 1 RCT in F/A
history
• Establishes AUGMENT® Bone
Graft as a safe and effective
alternative to autologous bone graft
in hindfoot and ankle fusion surgery
DiGiovanni C et al, JBJS 95(13), 2013
Note: FDA did not base its approval of AUGMENT® Bone Graft on radiologic
findings from the pivotal study, but instead relied on clinical outcomes.
AUGMENT® Bone Graft
Indications For Use Statement*
AUGMENT ® Bone Graft is indicated for use as an
alternative to autograft in arthrodesis (i.e., surgical fusion
procedures) of the ankle (tibiotalar joint) and/or hindfoot
(including subtalar, talonavicular, and calcaneocuboid
joints, alone or in combination), due to osteoarthritis,
post-traumatic arthritis, rheumatoid arthritis, psoriatic
arthritis, avascular necrosis, joint instability, joint
deformity, congenital defect, or joint arthropathy in
patients with preoperative or intraoperative evidence
indicating the need for supplemental graft material.
*Summary of Indications, Contraindications, Warnings and Precautions included
at end of presentation or may be found in product Package Insert.
Ready-to-Use Autograft Alternative
Kit Components Provided
Sterile Packed
Granules Soaked in
rhPDGF-BB solution
(0.3mg/mL) intra-operatively.
NOTE: Graft mixture should be left undisturbed for 10 minutes before being
implanted to ensure optimal saturation of the β-TCP particles. Ensure that the
entire volume of both components is a homogeneous mixture. The product
should be implanted within one (1) hour of mixing the two components.
17
12/8/2015
Product Preparation
Note: Any rhPDGF-BB liquid
remaining in the bowl after
implantation of a sufficient
amount of AUGMENT®
Bone Graft may then be
drawn up and used to
hydrate the already
implanted AUGMENT® Bone
Graft dispersed throughout
the fusion site
Surgical Technique Recommendations:
Tibiotalar Arthrodesis
1. Site Preparation
2. Debridement
Surgical Technique
3. Perforation
4. Feathering
18
12/8/2015
Key Application Pearls from
Clinical Trials
Soaked granules must be packed into the
perforations and under the feathering
Ensure good bony apposition between surfaces to
be fused
AUGMENT® Bone Graft should be used in the
same general manner and volume as cancellous
bone autograft
NOTE: Do NOT irrigate application site once graft has been implanted.
Technical Note
IMPORTANT: In order to
enhance the formation of new
bone, AUGMENT® Bone Graft
should be placed in direct
contact with well-vascularized
bone. In order to optimize bony
fusion, AUGMENT® Bone Graft
should be implanted to fill all
osseous defects and gaps,
while ensuring that it does not
prevent direct bony apposition
of the articular surfaces
intended for fusion
Surgical Technique
6. Hydration with
Remaining rhPDGF
solution
7. Fixation & Closure
NOTE: Do NOT irrigate application site once graft has been implanted

Biologic Augments: Why?
• Higher risk patients
• More revision and
complex cases
• Cost pressures to get
it right first time
Why? Non Union
Ankle Fusion:
78 ankle fusions, avg follow up 4 years
Majority of the patients were post-traumatic
“In this study, the nonunion rate was 41%, the
worst in the literature.”
Highest incidence in patients with
plafond/talus fractures
.
.
.
.
Frey et al FAI 15(11); 1994
Why? Non Union
. Subtalar:
. 184 consecutive isolated subtalar arthrodesis
. Overall nonunion rate = 16%
. Nonunion rate: Nonsmokers – 8%
Smokers – 27%
. Nonunion rate in: Primary fusion – 14%
Revision fusion – 29%
