BACKGROUND
![Page 3: Scolioza Congenitala](https://reader035.vdocuments.us/reader035/viewer/2022081723/5695d12f1a28ab9b02957f87/html5/thumbnails/3.jpg)
At the age of 6, Ashley’s mother noticed a
curve in her spine and her pediatrician
referred them to orthopedic doctors for
further evaluation.

MRIs and x-rays showed a 30 degree curve
in her spine (scoliosis) along with a vertebra
that was undeveloped on one side
(hemivertebra). There was no family history
of either scoliosis or kyphosis.

DIAGNOSIS
![Page 6: Scolioza Congenitala](https://reader035.vdocuments.us/reader035/viewer/2022081723/5695d12f1a28ab9b02957f87/html5/thumbnails/6.jpg)
During my examination of Ashley, I
confirmed the previous findings and
diagnosed:
Hemivertebra at Lumbar 1 vertebra (L1)
Decompensation (curving) of the trunk towards
one side due to hemivertebra
Congenital wedge vertebra (deformed vertebra)
at Lumbar 5 vertebra (L5)

TREATMENT
![Page 9: Scolioza Congenitala](https://reader035.vdocuments.us/reader035/viewer/2022081723/5695d12f1a28ab9b02957f87/html5/thumbnails/9.jpg)
While non-surgical bracing is an option in
some cases of scoliosis, it is ineffective in
cases such as this where a hemivertebra is
causing a progressive deformity. As a result,
surgery was performed to straighten
Ashley’s spine, realign her trunk, and
prevent further progression of her scoliosis.

Posterior Spinal Fusion
An incision was made from
the base of Ashley’s L4 to S1
vertebra. A titanium XIA 4.5
implant was affixed with
screws to the L4 and S1
pedicles to fuse the two levels
together preventing further
progression of Ashley’s curve.

Screws were not affixed to the L5 because
the L4 to S1 fusion provided sufficient
fixation. The L1 hemivertebra was stabilized
by the lower spinal fusion and was to be
observed rather than surgically altered.

Osteotomy
A wedge of bone was removed from the
right side of her L5 vertebra to correct the
deformity.

To aid healing and prevent infection, closure
of the wound was completed by Dr. Michael
Margiotta of Plastic Surgery.

Post Op Treatment

To prevent infection, a course of antibiotics
began during the operation and continued for
two weeks after surgery.
Due to the wedge resection of her vertebra,
Ashley used a wheelchair for 6 weeks and a
brace for 6 months to protect her body while
she healed.
After surgery Ashley came into the office
every six months and then once per year for
follow-ups.

CONCLUSION
![Page 18: Scolioza Congenitala](https://reader035.vdocuments.us/reader035/viewer/2022081723/5695d12f1a28ab9b02957f87/html5/thumbnails/18.jpg)
The temporary brace
and permanent internal
hardware stabilized
Ashley’s hemivertebra,
halting the progression
of her scoliosis, and
keeping her curve in the
range of 20 to 25
degrees even as she
grew.

Ashley is now a champion freestyle
swimmer with no physical limitations.
