Procedure
description
A posterior cervical
laminectomy is generally performed to decompress the
spinal cord within the cervical spine. The patient is
lying on their abdomen, with their head in a Mayfield head
holder (pins in a clamp hold the head in place). A linear
incision is made in the back of the neck, in a vertical (up
and down) manner. The surgeon will then dissect down,
through the subcutaneous tissues, to the fascia (firm membrane)
overlying the spinous processes ( bones protruding from the
back of the spine). The surgeon will then pull the muscle
away from the bones, exposing the extent of the roof of the
spinal canal on both sides. Generally, under microscopic
vision, the surgeon will drill or bite away the laminae (the
bone covering the cpinal cord). At this point, the spinal
cord which has been pinched by disk or bone, can be decompressed.
Sometimes the veins around the spinal cord can bleed, and
this is often controlled with local temporary pressure.
The surgeon will then close the various muscle and skin layers
with suture, and the skin with suture or staples. The
would is then dressed in a sterile manner.
Procedure
Risks
Posterior
cervical laminectomy is a frequently performed procedure.
Even though the risks of complications are relatively low,
there are risks. These can be broken down into two categories,
1) those related to the operative site, and 2) those related
to the risks of anesthesia.
Risks
related to the operative site:
Surgical
Exposure: The patient is placed in a prone position
(on their abdomen), with the head fixed in Mayfield head
pins. This is a clamp which fixes the head in position.
This is an extremely safe device, but there can be potential
lacerations in the skin, as well as infection.
In this position, there can be pressure sores, pressure
injuries to nerves, and injury to the eyes as a result of
pressure to them.
During surgical dissection, injury to muscle surrounding
the spine can occur.
Spinal Cord/Nerve
Root injuries: If there is any injury to the spinal
cord or nerve roots, the consequences may involve loss of
sensation, increased burning sensation, paralysis, weakness,
loss of bowel, bladder, sexual function. There may
be a spinal fluid leak, which could occur after a tear of
the covering of the spinal cord or nerve root.
Control of the diaphragm responsible for breathing, eminates
from the upper cervical spinal cord. If this area
is damaged, the patient may need a permanent tracheostomy
(hole in the windpipe), to provide a diversion of the route
air takes to enter the lungs.
General
Risks: These include such general difficulties,
such as bleeding, infection, stroke, paralysis, coma and
death. The scar on the neck may be tender, or may
heal in an unpleasant manner. There is also the possibility
that the surgery may not relieve the symptoms for which
the procedure was performed. The problem for which
the surgery was performed may recur, requiring additional
surgery in the future. In addition, although every
attempt is made to protect all areas of the body from pressure
on nerves, skin and bones, injuries to these areas can occur,
particularly with prolonged cases.
Risks of
Anesthesia: Blood clots in the legs, heart attacks,
reaction to the anesthetic, reaction to blood transfusion,
if it given.
Post-operative
care:
You may be
required to wear a firm cervical collar postoperatively.
There shall be no bending, twisting, or heavy lifting for
several weeks after surgery. Physical therapy may
or may not be implicated. Your doctor will gradually
ease your work restrictions, depending on your progress.
Remember to
keep the wound dry and clean. Notify your surgeon
of any drainage or temperatures greater than 101 Fahrenheit.
You may experience
some continuing incisional pain and occasional spasms in
the back of your neck from time to time. Any numbness
which you had in your hands prior to surgery may continue
as well. There are several steps you can take which
will help speed your recovery as well as give you the best
chance for a successful outcome.
- Immediately
upon discharge, contact our office and set up an appointment
for staple removal is one has not already been set up.
- Wear the
collar given to you by your surgeon. It should be
worn continuously except when showering or shaving, unless
instructed otherwise by your surgeon.
- Do no drive
until cleared with your physician.
- Avoid riding
in a car more than 50 miles.
- When shaving,
avoid tilting your neck back. When washing your
hair, do it in the shower and not in the sink.
- Begin an
exercise program of walking to gain strength.
- Lift nothing
heavier than one pound (one quart of milk).
- No jogging,
weight lifting, or other heavy exercise for now.
- Do not raise
your arms above your head.
- You may
shower with the incision covered.
- You may
engage in sexual relations.
- In doing
any activity in which you notice an increased amount of
neck, shoulder or arm pain, STOP. Your body is telling
you that you are doing too much.
- If you notice
any swelling, redness or opening of the incision, notify
your surgeon immediately.
- If you develop
fever or a stiff neck, notify your surgeon immediately.
- If you have
any questions, please do not hesitate to call your surgeon.
- Take your
temperature at 4:00 PM daily until clips/sutures are removed.
- Take your
medications as prescribed by your physician.
- It takes
6-18 months for a nerve to heal. You may have numbness,
tingling, creepy crawly sensations or fleeting pain during
this time.
