BAASTRUP d. (kissing spine) - False joint formed by
wide posterior spinous processes of the lumbar spine.
This may become a source of pain.
BACKBONE - See Spine.
BACK PAIN - nonspecific term used to describe pain
below the cervical spine
BACTERICIDAL - Causing the death of bacteria.
BACTERIOSTATIC - Inhibiting or retarding the growth
BANKS-DERVIN ROD - For scoliosis fixation; a multiple
level rod that is fixed with oblique spinous process
to contralateral lamina screws.
BELL'S PALSY - Paralysis of facial muscles (usually
one side) due to facial nerve dysfunction of unknown
BENIGN - Not cancerous; does not invade nearby tissue
or spread to other parts of the body.
BIOABSORBABLE POLYMER - A substance, such as some plastics,
which the human body can break down and absorb.
BIOCOMPATIBILITY - A characteristic of some materials
that when they are inserted into the body do not produce
a significant rejection or immune response.
BIODEGRADATION - The breakdown of organic materials
into simple chemicals commonly found in the body.
BIOPSY - Removal of a small portion of tissue, usually
for the purpose of making a diagnosis.
BLOOD-BRAIN-BARRIER - The barrier which exists between
the blood and the cerebrospinal fluid which prevents
the passage of various substances from the bloodstream
to the brain.
BMP-LIKE PRODUCTS - proteins that enhance mineralization,
which can increase bone formation.
BOHMAN - Posterior triple spinous process wiring technique
in the cervical spine to secure bone graft.
BONE - The hard tissue that provides structural support
to the body. It is primarily composed of hydroxyapatite
crystals and collagen. Individual bones may be classed
as long, short, or flat.
BONE DERIVATIVE - One of the substances extracted from
bone, such as bone morphogenic proteins (BMP).
BONE GRAFT - Bone which is harvested from one location
in an individual and placed in another individual (allograft
bone) or in a different location in the same individual
BONE HARVESTING - the removal of bone for transplantation
to another site. The most common sources are the iliac
crests because these bones contain a large amount of
cancellous bone, the inner spongy part, which is useful
for getting grafts to "take."
BONE MARROW - The tissue contained within the internal
cavities of the bones. A major function of this tissue
is to produce red blood cells.
BONE MORPHOGENETIC PROTEIN-2 (BMP-2) - one of a family
of BMPs- naturally occurring chemicals in the body-
that play a major role in bone growth. BMP-like products:
proteins that enhance mineralization, which can increase
BONE PLATE - Usually a relatively thin metal device
which is affixed to bone via screws. Bone plates are
used to immobilize bones or bone fragments such that
healing can occur.
BONE SCREW - A threaded metal device which is inserted
into bone. The functions of bone screws are to immobilize
bones or bone fragments or to affix other medical devices,
such as metal bone plates, to bones.
BOSWORTH - A fusion using an H-shaped bone graft in
BOVINE BONE EXTRACT - a BMP derived from the bones
BRACHIAL - Relating to the Arm.
BRADFORD - For kyphoscoliosis deformity; staged anterior
and posterior approach for interbody fusion and correction
BRADYCARDIA - Slowness of the heart rate.
BRADYKINESIA - Slowness in movement.
BRATTSTROM - Use of acrylic cement for C-1 to C-2 fusion.
BROOKS and JENKINS - Loops of wire around lamina of
C-1 and C-2 to hold bone graft between lamina.
BROWN-SEQUARD'S SYNDROME - Loss of sensation of touch,
position sense, and movement on the side of a spinal
cord lesion, with loss of pain sensation on the other
side. Caused by a lesion limited to one side of spinal
BURR - An electrical drilling tool for enlarging atrephine
(circular) hole in the cranium.
