Cost Effective Management for Different Biomaterials Used in Spinal Fusion Surgery

COST EFFECTIVE MANAGEMENT FOR
THE DIFFERENT BIO MATERIALS
USED IN SPINAL FUSION SURGERY

INTRODUCTION
Background of the Study
• A surgical repair or replacement is necessitated by
trauma, diseases or degeneration.
• The value of biomedical materials globally currently
stands at approximately $24,000M with dental and
orthopedic applications accounting for about 55%
of the total market for biomaterials.
• The use and requirements for biomaterials in tissue
engineering is strictly defined with biocompatibility
being the top of the agenda for the choice of any
material for use for their orthopedic or diagnostic
purposes.

INTRODUCTION
• A biomaterial is a substance that can has been
tailored to interact with the systems of biology for
the purposes of medical practice.
• These composites have the ability to be in
contact with the fluids of the body and tissues
from relatively long periods of time without
invoking any significant if any adverse reactions
with the body systems.
• Biomedical materials are used either of
therapeutic i.e. treatment, replacement or repair
of a tissue that functions in the body.
• Biomaterial can either be synthesized in the
laboratory or be of natural origin.
• Biomaterials are categorized into metals,

• Metals are the group of
biomaterials that is
most commonly used
due to the ability to
bear loads
• A good biomaterial of
metallic nature should
have the same values of
Young’s modulus as the
bone or the tissues for
which it is replacing.
• Cobalt-base alloys, stainless steel, titanium
alloys and pure titanium are among the most
commonly used metals as biomaterials.

Ceramics and composites
are mostly used on
dental applications
including fillings,
crowns and dentures.
Ceramics cannot be
applied in implantations
that required high
tolerance of loads
• PMMA-glass filter
and BIS-GMA-
quartz-silica filler
are the two most
commonly used
composites and
are mostly used
for dental filling
and restoration

AUTOGRAFTS
• Also known as autologous
bone or autogenous bone
graft.
• Refers harvesting of the
bone from a patient and
transferring it to the part of
the spine that is to be fused.
• Harvesting of the bone is
done from one of the bones
of the patient in the iliac
crest also known as the
pelvis.• Very few spine procedures include autograft
harvesting
