Rare polyphasic potentials to the anterior tibialis .
was cleaning out a wheat bin and his partner forgot to tie him off
outside and he fell about 25-30 ft and landed on his butt and lower
back because of the slope inside.
a neurosurgeon preformed a microdiscectomy for L5-S1 radiculopathy.
still having persistent/recurrent pain so the last week of October
the Dr redid a MRI of the L & S spine.
was enhancing epidural fibrosis partially encasing S1 nerve root an
L5-S1 annular disc bulge and moderate foraminal disc protrusion with
compression of L5 nerve root.
he had a EMG/NCS the impression said abnormal EMG/NCS with rare polyphasic
potentials to the anterior tibialis, peroneus longus extensor hallucis
longous,posterior tibialis an medial hamstring.
positive sharp waves in the posterior tibialis muscle as well.
this mean he will probably need more surgery or that the nerve damage
do test results mean?
fibrosis (EF) is a major cause of failed back surgery syndrome (FBSS),
which induces disabling radiculopathy for which no effective medical
disc protrusion is an important entity to recognize for a number of
of all it is relatively easy to overlook as it does not impinge upon
the spinal canal. Secondly as it does not narrow the subarticular
recess it compresses the exiting nerve root only, thus clinically
mimicking a posterolateral disc at the level above.
discs are common as is multilevel disease, missing a foraminal nerve
root compression leading to only one level surgical decompression
is a cause of failed back surgery.
back surgery syndrome (also called FBSS, or failed back syndrome)
is a misnomer, as it is not actually a syndrome - it is a much generalized
term that is often used to describe the condition of patients who
have not had a successful result with back surgery or spine surgery
and have experienced continued pain after surgery.
advances in surgical technology, the rates of failed back surgery
have not declined.
for failed back surgery syndrome may include physical therapy, nerve
blocks, medications, injections or a chronic pain management program.
