Spinal
Bracing Terminology
Categorizing
the host of spinal orthosis designs used in
contemporary patient rehabilitation can at times
be rather
difficult, because (1) there are so many of them,
and (2) most can be referred to in several
different ways.Some help was provided by a 1970s
task force on standardization of
prosthetics-orthotics terminology, which provided
a system of nomenclature that describes orthoses
in terms of the joints they encompass and the
desired control for those joints.
In this system,
spinal braces are described as sacroiliac (510),
lumbosacral (LSO), thoracolumbosacral (TLSO),
cervicothoraco lumbosacral (CTLSO), cervical (CO)
and cervicothoracic (CTO) orthoses. Control is
generally described in terms of spinal flexion,
extension, rotation and or lateral (bending).
While this new
nomenclature has helped, many traditional ways of
naming and categorizing spinal systems remain in
use. Orthoses may be classified:
- as to
rigidity (i.e. flexible vs. rigid);
- by the
presenting diagnosis (e.g. scoliosis
brace); or
- by details
or materials used in fabrication (e.g. plastic
body jacket).
The specific
name of an ortho sis may be an eponym (e.g.
Knight brace), credit the city or institution in
which it was developed (e.g. Charleston bending
brace), or reflect some other pertinent detail of
its construction or application. But because the
same orthosis is often known by different names
in different disciplines, special-ties and
geographic regions, the more complete the
description when discussing or prescribing spinal
braces, the less opportunity for confusion or
error.
In particular,
when prescribing a spinal orthosis, we recommend
including: the diagnosis, generic nomenclature,
eponym or common name, and additional
specifications (e.g. plastic body jacket TLSO
for spinal stability, bivalved with soft
interface); expected duration of wear; and
whether the device is to be worn during sleep or
in the shower.

'...I'm
Useful Again!' Down to Cases
Ann, 30, an otherwise-healthy, active wife
and mother of four, suddenly found her life
turned upside-down by events following the
discovery of a large desmoid tumor in her left
leg. A long and painful regimen of daily
radiation and chemotherapy treatments left her
weak, fatigued and unable to care for herself and
her family and yet yielded no progress. At
length, weary of a life diminished by therapy
side-effects and a "useless" leg, she
elected to proceed with amputation surgery. When she came a week
later to initiate prosthetic management, Ann's
high-level transfemoral amputation presented the
dual challenge of a difficult socket fit and very
short lever-arm with which to control a knee
component. Yet, this highly motivated patient
fully intended to return to her full, active
lifestyle, including chasing after kids and her
favorite pastime, bicycling.
Accomplishment of that goal
virtually demanded the ability to vary walking
speed easily and efficiently without the
resulting gait abnormalities experienced by most
above-knee amputees. For that reason, her rehab
team designed an advanced limb prosthesis built
around a microprocessor-control system. Despite
the complexity of this sophisticated new
prosthesis, Ann was soon on a treadmill, smoothly
walking through a range of speeds while her
prosthetist fed programming inputs into her new
system. From her first steps, it was obvious this
component selection was a good one.
Designing and fabricating Ann's
socket proved to be the greater issue. Her short,
finn, very round residual limb caused lateral
stability and internal rotation difficulties with
the initial socket attempts. In such cases,
patience and perseverance are essential to a
successful outcome.
Fortunately, both this patient and
her rehab team had plenty of both. After several
rejections, the socket] suspension challenge was
successfully addressed by a narrow M-L ischial
containment design with a silicone sleeve and
distal locking pin.
Today, Ann is back to living the life she thought
she'd lost, totally convinced she made the right
decision in choosing surgery. She has resumed her
household and "mom" roles and
participating in cross-country bicycle rides.
"For me, amputation was a
good thing," she says. "I'm living
again...I'm useful again!"
