80 cases of Cysticercosis were studied and analysed, which were diagnoses by biopsy at Seoul National University in the past three years from January-1978 to March-1980. The results were summerized as follows. 1. The relative incidence ratio of cysticercosis among 18,941 surgical specimens was 0.42%. 2. The age group between 11 and 50 years old occupied 87.5%. 3. Of the 80 cases, there were 38 males and 42 female patients, without significant sex predominence. 4. The common sites of cysticercosis were upper extremities (35.0%) and anterior surface of the trunk (37.5%) 5. Epidemiologically, there was marked predominence of rural area over urban area. 6. There were 8 cases (10%) of definite cerebral cysticercosis and 4 cases (5%) of suspicious cerebral cysticercosis. 7. In the cases of nodular masses of extremities, the parasitic infection, especiaily cysticercosis celluiosae, must be included in differential diagnosis distinguished from other soft tissue tumors.

PURPOSE: To evaluate normal variations and thus to avoid confusion in differentiation from lesions of the accessory structures (rhomboid fossa, foramen for supraclavicular nerve, conold tubercle) of the clavicle in chest radiographs. MATERIALS AND METHODS: We studied the variations of the clavicle in 300 chest radiographs (134 men, 166 women) and 355 dry bones (right 166, left 189; 151 men, 74 women, 130 unknown sex). RESULTS: In chest radiographs, the incidence of the depressed rhomboid fossa was 229 cases (39.5%;male 52.0%, female 29.9%);the flat type was 329 cases (56.9%;male 45.7%, female 65.7%);and the elevated type was 20 cases (3.5%; male 2.4%, female 4.3%). In the dry bones, the incidence of the depressed thombold fossa was 129 cases (57.3%;male 59.6%, female 52.7%);the flat type was 65 cases (28.9%;male 24.5%, female 37. 8%) ;and the elevated type was 31 cases (13.8%;male 15.9%, female 9.5%). The incidence of the foramen for supraclavicular nerve was 0.8% in chest radiographs, and 1.4% in the dry bones. The incidence of the elevated conold tubercle was 65.1% (male 64.0%, female 65.9%) in chest radiographs, and 96.9% (male 95.4%, female 100.0%) in the dry bones. CONCLUSIONS: The incidence of the depressed rhomboid fossa in chest radiographs was higher in men and the right clavicle. The incidence of flat rhombo~d fossa in chest radiographs decreased according to increase of age. The foramen for supraclavicular nerve was occasionally found (0.8% in chest radiographs; 1.4% in the dry bones).

The 213 first ribs Koreans were measured and morphologically studied. The results were as follows. 1. On average, the internal straight length of the first rib was 53.7mm (male), 49.9mm (female) ; the external straight length was 79.7mm (male), 75.4mm (female), the maximum straight length was 87.4mm (male), 81.2mm (female) ; the breadth was 15.2mm (male), 14.4mm (female) ; and the thickness was 5.5mm (male), 5.4mm (female). 2. The proportion of the scalene tubercle to the costal breadth was 0% to 90% (average 37%). 3. The incidence of the presence of the groove for the first thoracic nerve was 7.5%. 4. The common shapes of the articular surface of the head were ball-shape(41%), cylinder-shape (25%) and plane-shape (25%) ; and those of the tubercle were cylinder-shape (44%), saddle-shape (31%) and socket-shape (14%).

It is well known that the incidence of revision arthroplasty for the loosened total hip has been progressively increasing recently. And the problem is that the loosening rate of revision arthroplasty for the failed total hip replacement is much higher as compared with that of primary total hip replacement. In revision arthroplasty, Amstutz, in 1982, reported 9% incidence of mechanical failure and 43% incidence of femoral and 61% incidence of acetabular progressive radiolucencies with follow-up for an average of 2.1 years, and Pellicci, in 1985, reported 29% incidence of failure for total hip replacement that have been revised once in the radiolucent zone with the follow-up for an average 8.1 years, and Kavanagh, in 1985, reported that probable loosening occurred in 25% of revised acetabular components with follow-up for an average of 4.5 years. Cementless total hip replacement is successful in more than 90 of the primary cases for the last 5 years in our department. Therefore, not only in primary total hip replacement but also in the revision, it seems to be reasonable to perform the cementless total hip replacement as an alternative, particularlly, in young age group. During the period from April 1982 to December 1984, we have revised 12 loosened total hip replacement with cementless type. Average follow up was 1 year and 7 months. The age range of the patients was 23 to 64. The results are very promising without any evidence of loosening in all cases.

Knowledge of three-dimensional (3D) structure of the lung is very important for diagnosis and treatment of lung diseases. Two-dimensional (2D) tools (e.g. anatomy books) or traditional 3D tools (e.g. plastic models) are not sufficient for understanding 3D structure of the lung. The lung of a cadaver may not always be available for dissection, when it is needed. To overcome this problem, virtual dissection programs of the lung have been made. However, most programs include either 2D images that do not permit free sectioning and free rotating, or radiographs that do not reveal true color and have limited resolution. Moreover, it is necessary to make a virtual dissection program of each race and ethnic group. Thus, we attempted to make 3D image and virtual dissection program of the lung using a Korean cadaver in order to help medical students and doctors better understand 3D structure of the bronchi and pulmonary vessels. Both right and left lungs extracted from a 60-year old Korean male cadaver were embedded with gelatin solution, and were serially-sectioned with 1.5 mm-thickness using a meat slicer. Sectioned specimens from each lung were inputted into the computer using a scanner (300 x 400 resolution, true color). 2D images of the lungs were aligned on the alignment program which was composed using IDL language. The lung components, such as the bronchi and pulmonary vessels were manually segmented in 2D images on the CorelDRAW program. 3D images of the lung were reconstructed through the volume-based rendering of 2D images. With 3D images as the main features, the virtual dissection program of the lung was composed using IDL language. Various virtual dissection functions, such as sectioning 3D image of the lung at free angles to show its plane, identifying the bronchi and pulmonary vessels represented in the sectioned plane, and rotating 3D image of the whole lung or 3D image of the selected bronchi and pulmonary vessels at free angles, were established. This virtual dissection program of the lung was helpful in better understanding 3D location and shape of the bronchi and pulmonary vessels; it is expected to be used through Internet or CD-title as an educational tool for medical students and doctors.
