[Ilizarov's method. Histological and radiological aspects].

The Ilizarov method is an original technique of surgical lengthening of long bones. The constraints in compression and distraction obtained with this method favor the bony healing. The straining of extension induces stimulating consequences on the bone. The healing process is different from that of the fractures because the bony regeneration is accomplished by a membranous bony mechanism without intermediate fibrous or cartilaginous medium. The maturation occurs when the lamellated bone is present, at the end of the 4th month.

Herniation of calcifying discopathy in childhood: report of three cases.

Herniation of the calcified nucleus pulposus through the fibrous annulus is unusual in childhood. We present three cases and have surveyed 32 cases in the literature. Most herniations are located in the lower cervical and upper thoracic spine. Herniation is usually symptomatic. Usually calcification decreases after some months. For most children conservative therapy with bedrest and analgesics is sufficient.

[Separation of the distal humeral epiphysis in young children. Radiologic features].

Separation of the distal humeral epiphysis is infrequent in young children. Diagnosis is difficult since the entire condylar region is almost completely composed of cartilage. Marked sequelae occur if the diagnosis is not promptly made and arthrography is required to evaluate the extent of lesions. Two cases in children aged 2 1/2 years and one day are reported.

Osteopathia striata with cranial sclerosis.

We report a case of osteopathia striata, which is an osseous dysplasia with linear striations of the metaphyses of long bones. Our case is very unusual as there are no associated abnormalities of the bones. Osteopathia striata should not be mistaken for osteopoikilosis. Osteopathia striata is not only a peculiar roentgenologic feature: when it is diagnosed other abnormalities should be looked for, especially cranial osteosclerosis, which may result in complications.

Metastases to bone in medulloblastoma. A report of five cases.

Medulloblastoma is a relatively common intracranial neoplasm in childhood. Its extraneural spread was, until recently, thought to be a rare occurrence. Metastases are most commonly to bone. Five patients with medulloblastoma metastatic to bone are presented, and findings are compared to those of previous reports. Two of the five cases showed patchy extensive osteosclerosis of the pelvis and/or proximal femora. One case had concurrent lymph node involvement. In patients with past or present medulloblastoma and bone pain, metastases to bone should be excluded. Medulloblastoma metastatic to bone is a rare cause of extensive osteosclerosis.

Primary bone tumours of the pelvis in childhood--Ewing's sarcoma of the ilium, pubis and ischium (report of 30 cases). (Part I).

30 children with Ewing's sarcoma, the most common malignant pelvic tumour in childhood, were analysed. The diagnosis of Ewing's sarcoma is relatively easy and can be established in most of the cases on plain radiography. The diagnostic radiographic features of the tumour are discussed. The two most important conditions in differential diagnosis are eosinophilic granuloma and the rare primary bone lymphoma. Osteomyelitis should rarely cause confusion unless the clinico-radiographic findings are not properly evaluated.

Rare, primary iliac, pubic and ischial tumours in children (report of 14 cases)--Part II.

14 cases of rare, primary iliac, pubic and ischial bone tumours or tumorous conditions are reported. These include aneurysmal bone cyst, eosinophilic granuloma, cavernous haemangioma, osteoid osteoma, fibrous dysplasia, fibrous dysplasia with sarcomatous degeneration, chondrosarcoma, lymphoma and atypical malignant histiocytosis. The possibilities to be considered in the accurate radiographic recognition of primary tumours of iliac, pelvic and ischial bones are discussed.
