PERCS (SPML)
F.A.Q.
What does
Percs (SPML) refer to?
Percs (SPLM)
refers to an outpatient surgery usually under a general anesthetic
for the treatment of the spasticity and tight tendons that are found
in children with cerebral palsy. The name Percs comes from the
surgical term “percutaneous” which means using very small skin
incisions. The Percs (SPML) method has been developed over the last
20 years by Roy Nuzzo M.D. of Summit NJ. SPML stands for Selective
Percutaneous Myofascial Lengthening. I use the term SPML to refer
to the specific techniques taught by Dr. Nuzzo.
What is
exactly done with the Percs (SPML) procedure?
The Percs (SPML)
procedure involves releasing tight bands of tendon. This is done
where muscle and tendon overlap. These areas of overlap are areas
where a tendon starts to blend into a muscle. The tendon spreads
out and is thinner at this location and is called Myofascia.
When the myofascia is cut, the muscle under it can easily stretch
and lengthen.
What
part of the body can be treated with Percs (SPML)?
Some children
have tightness and spasticity in many locations in the legs, with
the Percs (SPML) procedure, many areas can be addressed during the
same procedure.
Common areas for
Perc (SPML) surgery are:
n
at the back of the
ankle for calf / heel cord tightness and spasticity
n
behind the knee for
hamstring tightness and spasticity
n
in the groin area for
scissoring gait and groin spasticity
What
age can be treated with Percs (SPML)?
Percs (SPML)
works well for children of all ages and for adults. Because Percs (SPML)
procedure uses micro incisions only about 2 mm long, there is very
little scar that forms as a result of the procedure. This is a good
feature since scar is known to be associated with recurrent
contracture. This allows Percs (SPML) procedure to work well for
all ages, including groups that have a reputation for recurrent
contracture following conventional tendon lengthening surgery such
as very young children and adolescents.
What are the
long term results of the Percs (SPML) procedure?
The best data
comes from Dr. Nuzzo’s web site where he reports a 5 year review of
278 cases. “Post op admissions were 0.01% (4 cases, single
night). Repeat procedures at any location were 10%. Recurrence of
operative site contracture occurred in 7%. There were no cases of
infection, over lengthening, significant hematoma. All surgeries
were performed supine. None required surgical room time in excess of
60 minutes. Parent satisfaction was positive in 100% with similar
follow up survey results one year later.” My results have been
similar.
Can the Percs
(SPML) procedure decrease spasticity?
Yes. Walking on
a contracted joint puts a strong pull on the muscle- tendon unit
with each step. This stimulates spasticity. Lengthening the
muscle- tendon unit decreases the spasticity in that area. The
beauty of Percs (SPML) is that since it is practical with the
minimal incisions to lengthen muscle- tendon units in many locations
in the lower extremities, spasticity can be decreased in many
locations.
What
is an alcohol nerve block?
The alcohol
nerve block is a common procedure that is done at the same time as
Percs (SPML) in children who have overactivity of the obturator
nerves, which are nerves in the groin that contribute to stiffness
of the hips or scissoring gait, in which the legs cross in front of
each other in walking. The alcohol nerve block takes the nerve from
an overactive spasticity related state to a more normal active
state. It does this by dissolving the fatty coating, called the
myelin sheath which is wrapped around the nerve. The nerve itself
remains intact. The myelin sheath can grow back in about 3 years.
The alcohol block is often used to decrease spasticity in the legs
when it is associated with groin tightness.
How is the
ankle area treated after the Percs (SPLM) procedure?
There will be a
cast from below the knee to the ball of the foot. Walking is
encouraged. It is best to put a shoe directly over the cast. One
type of shoe that may accommodate better to the width is the Vans
brand, because of the construction on the tongue and laces.
How is the
knee area treated after the Percs (SPML) procedure?
We will put on a
knee splint made of cloth and foam with Velcro straps after the
procedure. You can take this off for daytime activities. It should
be worn every night for a month to prevent sleeping in a curled up
position.
How is the
groin area treated after the Percs procedure?
Nothing special
is needed.
What
exercises are recommended after the Percs (SPML) procedure?
Long sitting.
This is sitting on the floor with the knees out in front as straight
as possible. This helps to keep the backs of the knees stretched
out.
Giant steps.
Encourage the child to take as big steps as possible. Try counting
the number of steps it takes to walk across the room. Then try to
walk across the room using giant steps. You should count fewer
steps.
Walking on
uneven ground. This
teaches the ability to deal with the unexpected. It also teaches
fast reactions. It helps in learning new ways to use the legs.
How soon can
children resume PT following Percs (SPML)?
Children who
have the Percs (SPML) procedure are allowed to walk when
comfortable, usually the next day. If not walking by the third day,
it is time to start! It usually takes 1-2 months to regain the
before surgery level of activity, then expect monthly improvement up
to 4-5 months from surgery. Physical Therapy can be very
beneficial and can be resumed within the week following the
procedure.
