The authors report 3 cases of primary intramedullary glioblastoma multiforme which is relatively rare among spinal cord tumors. They were located at the thoracolumbar, cervical and conus medullaris region respectively. Clinical, radiographic and pathological material are presented and the literature is discussed.

Spinal intramedullary teratoma is a rare tumor. A case of intramedullary teratoma of the conus medullaris with caudal development is presented. The patient underwent magnetic resonance imaging and then the tumor was removedd surgically. It was reportedwith the review of literatures.

Intradural spinal teratoma is very rare. A case of intradural teratoma attached to the conus medullaris associated with lumbosacral meningocele in a 16-year old boy is reported. Also comparable reported cases were reviewed in the world literature.

PURPOSE: To obtain spatial information on the acetabular fossa concerning `transacetabular screw' insertion through the acetabular fossa parallel to the quadrilateral surface for fixing an acetabular fracture. MATERIALS AND METHODS: Each hemipelvis harvested from 25 adult fresh frozen cadavers was sectioned into eight segments. This resulted in seven measuring points located along the outer margin of the acetabular fossa. At these points, we measured and compared the vertical thicknesses of cartilage and bone from the quadrilateral surface. RESULTS: The average thickness of the thinnest portion of the acetabular fossa floor was 3.9+/-1.9 mm. The entire thickness of the bone and cartilage measured vertically from the quadrilateral surface at the 7 points ranged from 12.7+/-2.1 mm to 17.8+/-3.8 mm. The thinnest safe space of exposed threads of the `transacetabular screw' inserted through the acetabular fossa was consistently just below the posterior conus of the lunate surface, measuring 4.8+/-1.6 mm (p<0.05). At the other points, it measured 8.3-10.8 mm. CONCLUSION: We suggest that `transacetabular screws' can be inserted safely if due consideration is paid to the spatial characteristics of on the acetabular fossa. Screw insertion into the postero-inferior portion of the acetbular fossa should be done carefully.

Intramedullary epidermoid tumors are rare. To our knowledge, this is the first description of a multiple intraspinal epidermoid tumor, including the intramedullary conus medullaris and an intradural lesion in the lumbar spine. The authors report the case of a 43-year-old woman presenting with progressive paraparesis. A thoraco-lumbar lesion was confirmed as an epidermoid cyst from histopathology. The clinical, radiological and surgical features, as well as a brief critical review of the literature are included.

The authors report clinical results of twenty-three traumatic thoracolumbar burst fractures treated by internal fixation with Kaneda device after anterior decompression during recent three years. Thoracolumbar injuries made up 28.9% of total spinal injuries and the burst fractures treated by anterior decompression and stabilization with Kaneda device constituted 19.0% of all spinal injuries. The burst fractures occurred most frequently at the age of twenties and thirties. The main causes of injury were fall and vehicle accident. Superior end-plate fracture type was most common according to the types of burst fracture. The first and the second lumbar vertebrae were frequently involved. No patient showed neurological deterioration after surgery. Conus medullaris lesions in burst fractures of the thoracolumbar junction have a high potentiality for functional recovery because the lesions are not due to discontinuity or severe crush injury but due to simple compression by bony fragments. The Kaneda device offered enough stability to enable early ambulation with good alignment and solid fusion.
