Diagnosis of brachial and lumbosacral plexus lesions.
[neuralgic amyotrophy]
To
most
doctors
,
brachial
and
lumbosacral
plexopathies
are
known
as
difficult
disorders
,
because
of
their
complicated
anatomy
and
relatively
rare
occurrence
.
Both
the
brachial
,
lumbar
,
and
sacral
plexuses
are
extensive
PNS
structures
stretching
from
the
neck
to
axillary
region
and
running
in
the
paraspinal
lumbar
and
pelvic
region
,
containing
100000
-
2000
00
axons
with
12
-
15
major
terminal
branches
supplying
almost
50
muscles
in
each
limb
.
The
most
difficult
part
in
diagnosing
a
plexopathy
is
probably
that
it
requires
an
adequate
amount
of
clinical
suspicion
combined
with
a
thorough
anatomical
knowledge
of
the
PNS
and
a
meticulous
clinical
examination
.
Once
a
set
of
symptoms
is
recognized
as
a
plexopathy
the
patients
'
history
and
course
of
the
disorder
will
often
greatly
limit
the
differential
diagnosis
.
The
most
common
cause
of
brachial
plexopathy
is
probably
neuralgic
amyotrophy
and
the
most
common
cause
of
lumbosacral
plexopathy
is
diabetic
amyotrophy
.
Traumatic
and
malignant
lesions
are
fortunately
rarer
but
just
as
devastating
.
This
chapter
provides
an
overview
of
both
common
and
rarer
brachial
and
lumbosacral
plexus
disorders
,
focusing
on
clinical
examination
,
the
use
of
additional
investigative
techniques
,
prognosis
,
and
treatment
.
