Bone Void Filler

Genex®

www.biocomposites.com

What are your options when you need to fill a void? 

1.) Allograft ? 

STRENGTH: Mildly osteoinductive.

WEAKNESS: Possibility of disease transmission, variable efficacy, no FDA regulation, some forms wash away easily, need to complete tissue tracking form, need to have informed consent of patient. 

2.) DBM (Cancellous chips)

STRENGTH:   It is mildly osteoinductive.

WEAKNESS:  How osteoinductive is it?  The product varies from lot to lot. 

ELISA measurements of BMP-2 in commercially available DBM’s
picogr/mg Lot 1 Lot 2 Lot 3 CV%
Allomatrix 97.5 30.1 28.2 76
DBX 51.4 40.9 36.6 18
Dynagraft II gel 49.2 38.8 25.4 32
Dynagraft II putty 39.5 30.8 29.5 16
Grafton crunch 40.8 30.5 29.0 19
Grafton gel 85.6 33.6 20.2 74
Grafton putty 61.3 51.9 29.0 35
Intergro putty 89.7 50.5 33.0 50
Osteofil paste 120.6 48.4 28.4 74
Kanim, Bae, et al. NASS 2003

Because DBM comes from human tissue, there is the risk of disease transmission and, of course, you must get the patient to sign an informed consent.

3.)  Infuse? 

STRENGTH:   Can grow bone at rates comparable to autograft

WEAKNESS:   Very expensive, limited FDA indications for use, significant side effect profile (antibody formation, ectopic bone formation, contraindicated in pregnant women, children under 18, and near tumors),  should only be used once in a patient’s lifetime.

4.)  β TCP? 

STRENGTH:   Excellent osteoconductive matrix, no risk of disease transmission, safe, proven efficacy, unlimited availability, multiple handling forms, FDA approved for a wide variety of indications, convenient application, cost effective.

WEAKNESS:  Not osteoinductive.

5.)  Platelet Jells?

STRENGTH:  Some efficacy in long bone use, available from patients own blood.

WEAKNESS:  Need to draw large quantities of blood, expensive centrifuge and disposables needed, preparation time, no osteoconductive scaffold, poor results in spine fusion, poor handling properties.
