Il s’agit d’une étude rétrospective portant sur 12 patients atteints
d´un ostéoblastome du rachis au C.H.U du Shafa.Yahyaian de Téhéran.
(IRAN)
Tous les patients étaient âgés de moins de 30 ans (âge moyen : 16
ans).
Le temps écoulé entre les premiers symptômes et le diagnostic
s’étalait entre 4 et 18 mois.
Le symptôme le plus fréquent était la douleur (67% des cas), la
déformation en scoliose était la cause de consultation dans 14% des
cas.
Dans la région cervicale, le patient consultait en raison de la limitation
des mobilités associée à des phénomènes douloureux.
Dans la région sacrée seule la douleur sans déformation était le
symptôme de découverte
Enfin chez l´enfant, seule la douleur a été le signe d’appel.
Les simples radiographies standard ont permis de faire le diagnostic
dans 50% des cas.
L’ostéoblastome était toujours localisé dans la partie postérieure de
la vertèbre.
Le traitement dans tous les cas a consisté en un curettage de la
totalité de la région.
Tous nos opérés ont guéri et, avec le recul que nous avons, nous
n’avons pas eu à déplorer de récidive.

Spinal osteoblastoma (prognosis and treatment): 12 cases.

Study aim: A retrospective study of 12 cases of spinal osteoblastoma.
Objectives; To identify factors associated with the development of
scoliosis and its manifestation.
Summary of background data ; painful scoliosis is a well recognized
sign of osteoblastoma but because of the small number of
previous reports, the outcome of the tumor in the spine is not well
known .
Patients and Methods; Ten factors were assessed including age,
sex, duration of symptoms, site of lesion, Cobbs angle at presentation,
chief complain at presentation, neurological involvement, type
of treatment, recurrence of tumor.
50% of the patients had scoliosis. All of the lesions were present on
the concave side of the curve. In the thoracic and lumbar localizations,
80% had scoliosis, but no scoliosis was seen on cervical and
sacral regions.
All patients were under 30 years. The mean time to diagnosis at our
center was 18/4 months. All of the cervical cases (2 pat.) had deformity
(cock robin) and restriction of range of motion. The lesion
was in posterior elements in all of the cases and localized on only
one side of the spine. The chief complaint was pain in 67%, deformity
in 16% and both (pain and deformity) in 17%. Radiological
examination was diagnostic in 58% of cases.
Conclusions: These findings support the concept that scoliosis is
secondary to asymmetric muscle spasm. The most common complaint
is pain and then deformity. In the cervical spine deformity
and restriction of motion are the chief complaints.
Pain spastically in children (under 13 y) is more obvious than deformity.
Treatment is curettage which should be as wide as possible.
There was no recurrence in our series.
