Abstract
Hydatid disease of the bone and soft tissue of the musculoskeletal system is uncommon.
The dissemination mode leads to local malignancy with severe prognosis.
Tunisia is an endemic area of the disease. Therefore we treated many patients affected the disease.
We retrosectivelly reviwed 6 cases of bone hydatid cyst from 1990 to 2010.
There were 3 males and 3 females.
The mean age was 13 years.
The localisation were 03 spinal, 2 in the proximal tibia and & localisation in trochanter.
The diagnosis were histoligical in all patient. the mean delay for the diagnosis was 3 years. One patient with spinal localisation had neurological complication paraplegia.
All the patient had surgical excision of the hydatid cyst.
Ther ewere 3 cases with local recurrence.
Because of the poor results with medical treatment, osseous hydatidosis must be treated by a radical operation with wide excision, adapted to each localization. In the main, the prognosis of osseous hydatidosis remains poor, especially with spinal and pelvic localizations, which are the most frequent ones.
The prognosis and treatment of osseous hydatidosis belong in the same category as a locally malignant lesion.
