Dr. Epstein has written extensively on
disc herniations involving the spine. Disc herniations are defined as an
extrusion (popping out) of the cushion between the vertebral bodies. When discs
herniate in the neck, they may compress the cervical spinal cord (central),
and/ or nerve roots (off to the side). Nerve root compression can produce
numbness, tingling or weakness, while spinal cord compression may result in the
loss of sensation, weakness in the legs, or even severe paralysis. Only a
subset of patients with disc herniations may require surgery. When these
operations are required they can be performed from the front or back of the
neck (cervical), mid back (thoracic), or lower back (lumbar spine).

Spinal stenosis
is the fancy term for narrowing of the spinal canal. You can be born with a
narrowed spinal canal (congenital stenosis), or may develop arthritic changes
as you age (acquired stenosis) which narrow your spinal canal. In the older population,
spinal stenosis is much more common than disc disease. Arthritic changes may
include calcified discs, calcified ligaments, calcified facet joints. Narrowing
(stenosis) in the neck (cervical), mid back (thoracic), or lower back (lumbar
spinal canal) may compress nerve tissue and produce numbness, tingling,
weakness, or paralysis. The treatment includes operations from the front or
back of the spine at any of these levels.

When there is too
much motion between the bones of the spine (vertebral bodies) the excess motion
can lead to pain, compression of the nerve tissue, and nerve damage. In the
neck (cervical spine) and lower back (lumbar spine) instability or a “slip” can
be seen on X-rays taken with the patient bending forward and backward. More
long-standing slippage can be seen on regular X-rays, and MR or CT scans. Slips
can be due to arthritic changes in the bones and ligaments, previous injury, or
can follow operations. Operations performed to “stabilize” the slip are called
fusions. Fusions can be performed from the front or back of the neck (cervical
spine: anterior diskectomy, corpectomy, or circumferential surgery), mid back
(thoracic spine), or lower back (microscope assisted diskectomy/laminotomy,
laminectomy [non-instrumented, instrumented fusions].

The
posterior longitudinal ligament is located in front of the nerve tissue in the
neck (cervical), mid back (thoracic), and lower back (lumbar spine). In some
patients, this ligament can become calcified (ossified). Ossification of this
posterior longitudinal ligament [OPLL] can compress the spinal cord or nerve
roots in the spinal canal. It is most frequently found in the neck (cervical).
OPLL can produce numbness, tingling, weakness, and even paralysis. Operations
performed to remove OPLL can be extensive. If performed in front of the neck,
it may require the removal of several vertebral bodies, the placement of a
graft and plate, followed by fusion of the back of the neck (circumferential
surgery). In some other patients, surgery from the back of the neck
(laminectomy with/without fusion) can be performed. Many patients demonstrate
significant postoperative improvement.

Tumors affecting the spine can
include benign (non-cancerous) tumors. They can be located in the bones, in the
spinal cord itself, or outside of the cord.

Tumors
originating within the spinal cord itself include benign astrocytomas, benign
ependymomas, and occasionally malignant gliomas or mestastases.

These are usually (95%) benign tumors originating
from the covering of the nerve tissue (dura). They are found mostly in the neck
(cervical) or mid back (thoracic) spinal canal. MR studies performed with dye
(Gadolinium DTPA) best demonstrate these tumors. CT examinations can evaluate
the degree of calcification while telling you about the surrounding bones. Many
of these tumors can be completely removed, often from the back of the spine.

These are tumors that originate from specialized
cells, which surround nerves (Schwann cells). They too are typically benign,
but are found throughout the neck (cervical), mid back (thoracic), and lower
back (lumbar spinal canal). Complete excision is feasible in the majority of
cases, while a small subset may not be fully removable. Again, a small subset
of these tumors may prove malignant, requiring additional radiation and/or
chemotherapy.

Operations can be done from the
front of the neck (cervical spine) to remove disc herniations. First, a
horizontal incision is made in the neck
(side to side in a wrinkle). Once the front of the spine is exposed, an
X-ray is taken on the operating table to confirm the operative level.
Microinstruments are used under an operating microscope to remove the disc and
arthritic tissue (spur, spondylosis arthrosis). A fusion is next performed with
a bone graft. The patient’s bone (autograft) is taken from the hip (iliac
crest: not the hip joint but the curved bone of the pelvis). The patient’s bone
heals better and faster in most studies than cadaver (allograft) bone. A
titanium plate is placed over the bone graft to keep it in place. An X-ray
taken on the operating table confirms placement of the bone graft and plate. A
drain is placed in the neck and the wound is closed. At the end of the
operation, patients awaken in a neck brace (CTO: cervical thoracic orthosis),
are examined (to make sure they are OK), and are brought to the recovery room.
A CT scan of the neck (cervical spine) performed the night after surgery check
graft/plate placement. Patients are transferred for observation to the
intensive care unit (older patients) or the step down unit. Most patients are
discharged within 2-3 days, depending on their needs.

Excision of two adjacent discs
may also require removal of the intervening vertebral body if arthritic changes
extend behind that body (bone). This operation is similar to that described for
the 1 level diskectomy/fusion but requires more extensive decompression
(removal of 2 discs and arthritis) with a longer graft obtained from the
patient’s hip (iliac crest). Arthritis is removed with diamond drills and microinstruments
under the operating microscope with monitoring the nerve potentials of the
spinal cord (SSEPs) and nerves (EMGs).

Patients with arthritis, and particularly, multiple level
OPLL, may require the removal of several vertebral bodies (bones) of the neck
(cervical spine). The approach from the front of the neck requires a longer
horizontal incision. Intraoperative X-rays are similarly obtained to confirm
the level of surgery after retractors (instruments to keep the tissues apart)
are placed. Diamond drills, microinstruments, an operating microscope, and
spinal cord monitoring are critical to successfully remove OPLL. Here, usually,
a long, straight cadaver (allograft) graft is required to span multiple levels;
a hip graft here is usually too curved and short. A longer titanium plate is
placed over the graft. To reinforce and help prevent these larger grafts/plates
from coming out, under the same anesthesia, a fusion from the back of the neck
is performed.

Removal of a disc located off to one side of the spinal
canal is performed in some instances from the back of the neck. This usually
requires removing a portion of the bone in the back of the neck (laminotomy)
above and below that disc herniation. Disc herniations can be removed utilizing
diamond drills for bone removal, and microinstruments under the operating
microscope. Spinal cord and nerve root monitoring (SSEP, EMG) employed
throughout add to the safety of surgery.

Patients with compression of the spinal cord over several
levels may require a laminectomy. A laminectomy includes removal of bone (the
laminae) from the back of the neck. Select older patients with significant
arthritic disease or calcified discs in the front of the spine may benefit from
this operation if they have a good cervical curvature, and their spine is not
straightened or bent forward. Those with arthritic disease behind the spinal
cord and a normal spinal curvature can have surgery, performed through the back
of the spine.

If a disc herniation compresses one specific nerve root and
is not accompanied by significant arthritic changes or instability (too much
slippage), a microscope-assisted diskectomy may be appropriate. To adequately
expose the nerve root and accompanying arthritic changes or stenosis, more bone
can be removed (laminotomy, partial laminectomy). Once the pressure is taken
off the nerve root (decompressed), the disc space is entered to remove
additional loose free fragments and reduce the risk of disc recurrence (another
piece of disc popping out). Although “fashionable” (minimally invasive)
alternatives are now available, many carry a higher risk of infection and
spinal fluid leak. Furthermore, the full extent of disease may not be
recognized, limiting the patient’s recovery.

For patients with more extensive arthritic disease of the
spine, an operation removing several lower back bones (laminae) may be
warranted. These procedures remove
arthritic disease (spur, spondylosis, ossified yellow ligament), provide more
room for narrowed spinal canals (decompress stenosis), and may or may not
require excision of disc herniations, Together, X-rays, MR, and CT studies
define the full extent of arthritic disease. Many of these operations are
performed in older patients (50’s-80’s), although a subset born with narrowed
spinal canals may develop symptoms earlier (30’s, 40’s). If there is no
evidence for abnormal motion between bony levels (no slip, instability),
multilevel laminectomy without fusion may be the appropriate operation.
Furthermore, if the amount/extent of bone removed during the decompression
affects stability, a fusion may be required.

If patients have evidence that the spine is moving too much
(unstable) on X-rays (plain X-rays, flexion/extension views), MR or CT studies,
a fusion may be required at the time of surgery. Furthermore, where the
operation includes the removal of bone needed for stability, fusions may be
warranted. These operations are typically performed in conjunction with single
or multilevel laminectomies. Fusions can also be performed form the front or
the back of the spine.

In select older patients, more rarely younger individuals,
non-instrumented lower back (lumbar) fusions may be required. Indications
include: (a) massive disc herniation (central), (b) arthritic slip in patient
with osteoporosis, (c) patient with cyst popping out of the facet joint
(synovial cyst), (d) other. These operations are most typically combined with
multilevel laminectomies in older osteoporotic patients and can be performed
over multiple levels. They utilize the patients own bone obtained from the
laminectomy. Patients are often braced for 3-4 months. CT scans and
Flexion/Extension X-rays are utilized to document fusion.

In patients with unstable lumbar spines, instrumented
fusions may be required. Indications for fusion are multiple: (a) disc excision
particularly in a younger patient resulting in instability, (b) removal of a
facet joint, (c) chronic slip in the bones (spondylolisthesis), (d) fracture in
the bone between the facet joints (spondylolysis), (e) other. Fusions performed
with laminectomy often utilize the bone harvested from the laminectomy
(autograft) site and do not typically require bone from the hip (iliac
autograft). These operations are performed with monitoring and fluoroscopy.
Patients usually wear a body brace from 3-4 months or until fused based on both
Flexion/Extension X-rays and CT scans.

Plain
X-rays of the spine taken from the front (AP or anterior/posterior) or the side
(lateral) yield important information regarding the alignment of the spine.
Flexion and extension X-rays detail whether there is any abnormal motion
(instability) of the spine when the patient flexes forward or extends backward.

Identification
of spinal disease can be confirmed with both MR and CT studies. MR (Magnetic
Resonance Imaging) examinations do not involve radiation. They best document
the soft tissues (nerves, spinal cord) of the spine, and the soft-tissue
disease compressing the nerve tissue (discs, tumors). On the other hand, CT
scans better demonstrate bone detail such as arthritic changes, stenosis (narrowing
of the cervical spine), and calcified discs.

The risk of neurological damage during operations on the
neck (cervical), mid back (thoracic), and lower back (lumbar spine) can be
minimized by utilizing intraoperative monitoring. Somatosensory Evoked
Responses (SSEPs) study the electrical potentials in the spinal cord from the
hands and feet, through the neck to the brain. If changes occur in these
potentials while putting the tube in the throat at the beginning of surgery
(intubation), during operative positioning, or during the operation itself,
adjustments to help protect the spinal cord can be made. The electrical
potentials of the nerves themselves (EMG’s) can also be monitored during
selected intervals of operations from the front or back of the spine.

In
conjunction with her colleagues in Anesthesia, Dr. Epstein utilizes “Bloodless
Spinal Surgery” in appropriate cases. This technique is particularly useful in
lower back (lumbar) surgery performed with or without fusion. It has proven
useful in patients whose religious beliefs don’t allow for the use of blood
products (i.e. Jehovah’s Witnesses). “Bloodless Surgery” can be utilized in the
majority of healthy individuals. Preoperative blood donation is avoided (with
its risks of infection, receiving the wrong unit, removal of coagulation
factors), along with its cost. At the beginning of surgery, the patient’s blood
is removed (1-2 units based on your preoperative blood level); patients are
given fluids to maintain a normal blood pressure. During the operation, less
blood (fewer red cells) is lost. At the end of surgery, the patient’s fresh
blood is returned. Most patients have not required additional blood
transfusions.

Dr. Epstein has recently studied whether artificial bone can
be used to expand and supplement bone taken from the patients themselves
(autograft) during different types of procedures. Beta Tricalcium Phosphate
appears to be just such a promising bone expander.
