[Low-grade central chondrosarcoma: difficult diagnosis in an adolescent girl].

Central chondrosarcoma of the tibia is exceptional, particularly in young patients. Low-grade tumors raise difficult problems for histological distinction with enchondroma. We report a case of grade 1 chondrosarcoma located in the upper portion of the tibia in a 17-year-old girl. After radical surgery, outcome was favorable with no recurrence or metastasis at three years follow-up. The distinction between low-grade central chondrosarcoma and enchondroma is one of the most difficult challenges in bone pathology. Clinical, radiographic and pathological data must be considered together to reach certain diagnosis.

Hydatid cyst of bone: diagnosis and treatment.

Osseous hydatidosis is a rare occurrence of hydatid disease. Anatomoclinical changes are, however, peculiar to this localization. From the anatomopathologic standpoint, this localization marks the torpid, insidious progression of the parasite into bone tissue, leading to an immediate diffuse, extensive, invasion process, so complete surgical eradication is rarely possible. From the clinical standpoint, whatever the localization may be, we are surprised by the latency of this affection, the patient being treated at an advanced stage, when radiologic lesions are already extensive, and the complications, especially in the spinal area, are severe. Owing to the poor biologic findings, the diagnosis of osseous hydatidosis is still primarily based on roentgenographic findings. Sometimes, however, the diagnosis is established only after surgery. Treatment of osseous hydatidosis is closer to oncologic therapy than to the usual surgical treatment of visceral hydatid cysts. 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.

[Femoral head necrosis after intramedullary nailing of the femur in adults].

An avascular necrosis of the femoral head occurred after intra-medullary nailing of a femoral diaphyseal fracture. This complication may be related to the posterior situation of the proximal insertion hole just posterior to the trochanteric notch and piriformis fossa as demonstrated by the CT scan. This situation of the nail may cause injury to posterior branch of the circonflex artery at the time of rod insertion. Even if it appears exceptional in adult patients with intra-medullary nailing, this potential complication and the anatomy of the superior extremity of the femur should be known.

[Fracture dislocation of the ankle with retro-tibial luxation of the fibula (Bosworth fracture) . Apropos of a case].

The authors present a case of fracture dislocation of the ankle joint with the proximal part of the fibula entrapped behind the tibia ; Bosworth's fracture. This fracture was described for the first time in 1848 by Hugier, and classified by Bosworth in 1947. In our case, diagnosis was not done in a first time, and closed reduction failed. This fracture was operated on and open reduction was performed. At the present time, the functional result is good.

[Tuberculosis of the trochanter. Apropos of 17 cases].

This paper presents a short study of 17 cases of tuberculosis of the greater trochanter seen during a period of 19 years at the National Orthopaedic Institute in Tunis. The onset of the infection is slow with patients presenting at a mean of 7 years after initial symptoms. The diagnosis is confirmed by biopsy and culture of the organism. Management is based on treatment with antituberculous drugs, although surgical excision of the lesion is sometimes required. Successful resolution of the symptoms is usually achieved unless the hip joint becomes involved. Our patients showed good results at a mean follow up of 5 1/2 years.

Osteoid osteoma of the acetabulum.

Osteoid osteoma of the acetabulum can be expected to cause nonspecific symptoms of hip inflammation. In a sixteen year old girl, investigation by routine radiographs and a bone scan suggested a focus of inflammation with a nidus and sclerosis of the acetabulum and overgrowth of the head and neck of the femur. Removal of the lesion by an anterior approach with dislocation of the hip gave excellent results when seen after three years with a normal gait and normal hip motion.

Extensive vertebral hydatidosis. A study.

An exceptional case of vertebral hydatidosis with involvement of the cervical, dorsal, lumbar and sacral segments of the spine is presented. Vertebral hydatidosis is a rare form of hydatid disease. It is found in less than 2% of all cases in echinococcosis. The initial parasite localization is usually univertebral. Extensive primary lesions were related to massive infestation by tapeworm ova at multivertebral levels. At this stage, the disease presents as a malignant tumor resistant to all surgical procedures. The prognosis is poor because of severe neurological complications and inexorable spinal destruction. The hope remains that in the future an effective medical parasiticidal treatment will be available.

[Transverse fracture of the sacrum: value of imaging. A case report].

Transverse fractures of the sacrum with major displacement are rare and often misdiagnosed. A case of transverse fracture of the sacrum with cauda equina injury is reported. The diagnosis was not recognized initially. Conventional radiographs of the pelvis failed to demonstrate the fracture. True lateral sacral views and CT scan with reconstructions allowed analysis of the different sagittal fracture lines to facilitate surgical planning. These examinations should be considered in all patients with history of high energy trauma and clinical signs indicating lumbosacral injury.
