1.Normal CT anatomy of the calcaneus
Journal of the Korean Radiological Society 1986;22(5):866-872
Normal sectional anatomy of the calcaneus with multiplanar CT examination was studied in 5 volunteers as thebackground for interpretation of various abnormalities. Major 3 sectional anatomy including plantar, coronal,sagittal and additional tuberosity planes are described. With CT examination of the calcaneus, 1. More detailedanatomy of 3 facets of subtalar joint(anterior, middle, and posterior facet) can be well visualized. 2. Itsclinical applications in the tarsal trauma, tarsal coalition, subtalar infectin, degenerative arthritis, clubfoot, pes planus and tarsal tumor could provide much more informations, which not obtained by conventionalradiographic studies.

Malignant fibrous histiocytoma is a rare malignant tumor of histiocytic origin, arising from either bone, or soft tissue. Six cases of malignant fibrous histiocytoma are presented with emphasis on radiographic features. Five cases are of primary bone origin and one of soft tissue. Ill-defined osteolytic bone destruction with no sclerosis and with no periosteal reaction is the principal radiologic feature of the malignant fibrous histiocytoma of bone. Therefore, malignant fibrous histiocytoma should be considered in differential diagnosis of primary intraosseous or extraosseous malignancies.

INTRODUCTION: The fixation strength of transpedicular screw system in the vertebral hody relied on bone quality and anatomical characteristics of vertebral pedicle, designs of screw and types of connection(rod or plate) with screw. The purpose of this study is to verify the biomechanical nature of the transpedicular fixation in spine under various conditions with porcine vertebrae. MATERIAL AND METHOD: Fresh porcine vertebrae and the custom-made screws were used in this experiment. To reduce the errors caused by vertebral bodies of different size and quality, vertebral bodies having regular range of pedicular width(10.0 to 11.5mm) and hone density(more than 1.0 gm/cm2) were used. The pedicle screws were inserted in the same procedure and axial pull out test was performed with using the Material Testing System(lntron8511, Canton, USA). The experiments were performed in four types to assess the difference of strength accroding to designs of the screw hy using two group of screws. The first group of screw was designed according to the outer and inner diameter and the second group was designed according to the shape, pitch, and thread profile of screw. Experiment I was perfomed to evaluate the effect of screw diameters on the biomechanical pull-out strength hy using the first group of custom-made pedicle screw which fixed all other factors except the diameter of screw. Experiment I was to verify the effect of screw shape, experiment III to verify the effect of pitch and experiment IV to verify the effect of thread profile. RESULTS: The results of experiments were summarized as follows: Experiment I showed that the screw of larger outer diameter had greater holding strength. Experiment II showed that the holding strength of cylindrical shaped screw is superior to that of conical shaped screw. Experiment III showed that there is no statistical significance between different modes of pitch. Experiment IV showed that the holding strength of buttress shape of thread profile is superior to that of V-shape. CONCLUSION: It seemed that the fixation strength of the screw was more powerful with 1 mm increment of outer diameter in 4-7mm of outer diameter, 3mm of pitch and buttress shape of thread of the screw with the same operation technique.

This study was undertaken to examine the possibility of predicting the stage of brain abscess presoperatively,which may markedly influence on the decision how to manage the patients suffering from intracerebral abscesses. Atotal of 17 patients with brain abscesses, who were treated with surgery and diagnosed pathologically, wereretrospectively analyzied with particular attention to the correlation of CT and histopathologic findings. Wefound that preoperative CT findings could not provede any possibility on the decision of abscess staging.Therefore, we suggest that the sequential CT scans should be done in patients with susupectd brain abscess forevaluation of abscess staging.
