Q

Autograft

A

Historically requires additional surgical site
Spinous processes are limited in quantity and often require extender
Autograft still considered gold standard
Patient’s own bone is better but what about smoker/diabetic/osteoporotic

Q

DBM Putty

A

2 ingredients - Demineralized bone (particles or fibers) and carrier that improves handling characteristics
510k required as result of added carrier compound
Offered in putty or injectable paste
Room temperature
2 year shelf life
Grafton (Osteotech/Medtronic)- glycerol carrier
DBX (Depuy) cannot be irrigated will wash away

Q

DBF (Demineralized Bone Fibers)

A

Long fibers that have been demineralized
Entangle and become similar to putty
100% bone - no carrier
room temp
2 year shelf life
Theory is cells prefer to grow along a liniar scaffold as opposed to jumping particle to particle
Relatively new - not many competitors

No Cells - still need osteogenic component
Handling characteristics close, but still not like putty

16
Q

Synthetic Peptides

A

I-Factor (Cerapedics) is only product on market
On a collagen molecule there are segments (peptide - 15 that grab onto osteoblasts

I-Factor is anorganic bone mineral (ABM) that has synthetic P-15 cound to it
The ABM is bone derived calcium phosphate particles

17
Q

BMP

A

Infuse - rhBMP-2
recombinant human bone morphogenic protein type 2
Single protein - aka Growth Factor, inherent in natural bone

Osteoinductive - signal only
BMP is 1,000,000 greater than native human levels

Intra-operatively combined wiht collagen spone carrier (20 minutes)
Recruits MSCs to site and signals them to change to osteoblasts
Was declining, now stabilizing
2010 900m 2015 400m

Expensive $1000/cc

18
Q

Amnion

A

?

19
Q

BMA

A

Primary purpose is to extract stem cells from a boney site such as the sternum or iliac crest.

Machine utilizes centrifugation to separate cell types

For spine, multiple pulls are taken from ilium
15 min of spinning to separate
Needs to be combined with allograft or synthetic scaffold (adds to overall cost)

High variability with respet to platelet concentration and residual leukocyte content
Low numbers of cells has been reported

Magellan (Arteriocyte)
SmartPReP 2 (Terumo/Harbest)
Biomet BioCue

20
Q

PRP

A

extract platelets rich in growth factors
Often same machine as BMA
High variability with respect to platelet concentration and residual leukocyte content
Science is not great on promotion of bone
Science is better on soft tissue side

22
Q

Nuvasive

A

Ground Bone - then cleaned
Contains scaffold signal cells
Cell portion of product is NOT demineralized 20% of demin bone particles added to final product
Why did they add this? probably a flaw in their original formulation

Cell Characteristics
Claim 3m cells but %MSCs unknown
Contains cells other than that related to bone formation
MSC count variable and completely based on donor

Morserlized 1cc 5cc 10cc 15cc

OsteoCel Plus 1st generation
poor handling less expensive

OsteoCel Pro 2nd generation
Stickey, stays together better, premium price

23
Q

Trinity Elite

A

Made by MTF
Scaffold, signal, cell
MSC count completely based on donor variables
Contains sells other than bone forming

Trinity Evolution 1st gen
is NOT demineralized - 20% demineralized bone particles added
Contains minimum of 250,000 cells/cc 50,000 of which are validated to be MSCs
Morselized only 1cc, 5cc, 10cc 15cc

Trinity Elite 2nd generation
Improved handling
More cells
Allogenic bone with cortical fibers - like brillo pad
Claim 500,000 cells 100,000 of which MSCs or osteoprogenitor
Noe demineralized - some demin added
Priced higher but coming down due to contracting

24
Q

BioMet Spine

A 
not demineralized, some demin added
250,000 cell/cc MSC unknown
MSC count based on donor
Morselized only
limited clinical data
sells other than bone forming
Distributed by biomet reps only
25
Q

600,000 cells
Endogenous bone forming cells including MSCs, OPCs and OBlasts
Vascular Endothelial Growth Factor(VEGF) is important to angiogenisis
MSCs are rich with VEFG as with blood
MSCs based on donor
Ready to use out of package - no decanting
thaws 15min

26
Q

Vivigen Depuy Synthes

A

Made by LifeNet
Cell count unconfirmed
They play down stem cell rhetoric
OP and OB attached to ground bone substrate
Linage of cell further along towards becoming bone
Linage cells are committed unlike MSCs
1 form only
MSC count based on donor
Delivery system gotten high praise from surgeons
No known data

27
Q

Map3 RTI Biologics

A

Made by RTI
Demineralized cortical cancellous bone chips are scaffold and signal
Cryogenically preserved, viable multipotent adult progenitor - class cells are packaged separately
Osteoprogenitor cells suspended in liquid and cryogenically preserved
Interoperatively combined with provided substrate - chips or strips -HOW many actually stick?
Lineage cells already committed - no replication
Cell count completely variable
Limited forms
Questionable handling
Extra prep time required to combine cells and substrate
Not enough time for cells to adhere

28
Q

Allostem All-in-one solutions

A

Designed to mimic autograft
3 necessary ingredients to grow bone - scaffold, signal, cells
Each component connected to each other
Cells are already attached to cancellous scaffold
BMPs are proteins found in the scaffold that are exposed during demin process
AlloStem can be irrigated and won’t wash away - others combined intra-operatively combined with synthetics don’t have enough bonding time. Can be irrigated away.
When RFPs come out, are all costs considered?

29
Q

Allostem Purer Cell Product

A

Our patented process ensures a consistent and reproducible cell count each time regardless of donor
Process provides knowable reproducible and consistent population of living, viable MSCs 66,250/cc
Only living viable MSCs attach to substrate
MSCs self select with natural ability to adhere to substrates while other immunogenic cells types wash away
MSCs are non-immunogenic
MSCs proved to multiply and differentiate into osteoprogenitor and osteoblasts

30
Q

Allostem Handling/Configuration

A

Allostem is an all in one fusion solution that is easy to use - thaw, rinse, implant
can irrigate in situ
Morsilized
Multiple sizing options to fill in cages or bone voids including MIS applications
Intact
Multiple shape options to fill cages or voids
Compressible and sponge like allowing for mushrooming out of cages to bridge endplates in disc space
