Study Design. Retrospective clinical study.
Objective. To show retrospective analysis of 21 con-
secutive patients who underwent simultaneous surgical
treatment for progressive spinal deformity and coexisting
intraspinal pathologies (tethered cord and/or diastemato-
myelia).
Summary of Background Data. The classic advocated
approach in patients with congenital spine deformity as-
sociated with intraspinal anomalies is first to perform
surgery for the intraspinal pathologies and then surgery
for correction and stabilization of the deformity 3 to 6
months later. To our knowledge, there is no study on
simultaneous surgical treatment for these 2 associated
conditions.
Methods. In the surgery; after the exposure of the
determined levels, placement of all pedicle screws was
performed as the initial part of surgical procedure. Then
surgical treatment for intraspinal pathology was per-
formed by the neurosurgical team and then followed by
completion of instrumentation and correction of the de-
formity. Additional anterior surgery was done later to
prevent pseudarthrosis and crankshaft phenomenon.
Results. The mean age of the patients at presentation
ranged from 3 to 19 years (mean, 13 years). There were 17
female patients and 4 male patients. Four patients had
neurologic deficits at the time of presentation, and all 4
had associated kyphosis. The mean operation time was
9.3 hours (range, 7–12 hours) and the mean blood loss
was 1980 mL (range, 1500 –3000 mL). The average fol-
low-up was 6.8 years (2–12 years). None of the patients
experienced deterioration in their neurologic status after
surgery. None of the patients had infection, pseudarthro-
sis, or loss of correction during the follow-up visits.
Conclusion. The simultaneous surgical treatment for
congenital deformity and intraspinal abnormality does
not involve significant complications and seems to be an
alternative and safe treatment option.

Congenital scoliosis and/or kyphosis occurs as a result of
either a failure of formation or a failure of segmentation,
or both.

This most frequently occurs in the first 8 weeks
of prenatal development. During this time, the bony ele-
ments of the spine are forming, and the neuraxis is com-
pleting its infolding, closing the neural tube.

These
events are closely related, and any intrauterine event that
causes congenital scoliosis and/or kyphosis could also be
associated with an intraspinal anomaly. These anomalies
include tethering of the cord, diastematomyelia, lipoma
and lipomeningocele, teratomas, and syringomyelia.
The intraspinal anomalies can cause progressive neu-
ral loss with growth and curve progression. In addition,
they greatly increase the risk of neurologic injury during
surgical correction of the deformity.

ported that 38% of the 42 patients in their study had an
intraspinal anomaly.
Congenital scoliosis and/or kyphosis due to the pres-
ence of vertebral anomalies cause an imbalance in the
longitudinal growth of the spine. Being a developmental
anomaly, it is often associated with intraspinal, genito-
urinary, cardiovascular, and other general abnormali-
ties.

Congenital deformities of the spine are relatively
rigid with a concurrent danger of neurologic complica-
tions.

All these factors, including the presence of in-
traspinal abnormalities, are important in decision-
making and the management of congenital scoliosis.
The classic advocated approach in such patients is first
to perform surgery for the intraspinal pathologies and
then surgery for correction and stabilization of the de-
formity 3 to 6 months later.

To our knowledge, there
is no study on simultaneous surgical treatment for these
2 associated conditions.
In the current study, we have retrospectively analyzed
21 consecutive patients who underwent simultaneous
surgical treatment for progressive spinal deformity and
coexisting intraspinal pathologies (tethered cord and/or
diastematomyelia).
Materials and Methods
We retrospectively reviewed the records of 21 consecutive pa-
tients with congenital scoliosis and/or kyphosis associated with
intraspinal abnormalities treated by simultaneous surgery be-
tween the years 1994 and 2004.
