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.

6.Intradural Spinal Teratoma Associated with Meningocele: Case Report.
Journal of Korean Neurosurgical Society 1979;8(1):157-164
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.

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.

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.

9.Multiple Intramedullary and Intradural Epidermoid Cysts in the Conus Medullaris and the Lumbar Spine: Case Report.
Journal of Korean Neurosurgical Society 2003;33(5):512-513
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.

STATEMENT OF PROBLEM: Various double crown systems have been used with removable partial dentures in the clinical field. Although retentive force between inner and outer crown are affected by several factors, differences between the retentive forces of different double crown system types are expected. PURPOSE: The purpose of this study was to evaluate the initial retentive force of outer crowns fabricated by the conventional casting technique in conus and hybrid double crowns. MATERIAL AND METHODS: Ten double crowns were fabricated. The groups were as follows. Group 1, double crowns of hybrid inner and outer crowns using the conventional casting method; Group 2, double crowns of conus inner and outer crowns using the conventional casting method. Tensile strengths of double crowns when the inner and outer crowns were separated on a universal testing machine were measured. These values of retentive force were then statistically analyzed using the Kruskal-Wallis test. RESULTS: Retentive force in group 2 was significantly higher than that in group 1 (p<.05). CONCLUSION: The initial retentive forces of double crowns were affected by the types of the double crown system.
