Monostotic Fibrous dysplasia is a relatively rare condition. Three such conditions are experienced at the Dept. of Orthopedic Surgery, Han-II Hospital during the period of September 1970 to June 1972. Two of three cases were involing shaft of left and right tibia respectively, one of which was complicated by pathologic fracture. The third case was on greater trochanter of right femur. All of three cases were treated with curertage and bone graft. Excllent results were obtained.

Fracture of the shaft of the humerus had been treated by many different way, such as hanging cast, shoulder spica cast, abduction splint, and Velpeau bandage, etc, The authors have employed the new trianglar splint designed by ourselves for the 54 cases of fracture of the humeral shaft from Jan., 1965 to Oct., 1976 in the department of Orthopedic surgery of Han-il Hospital. In our experience, the triangular splint method is useful for not only fracture between the head of the humerus and supracondylar region, but also shoulder joint injuries and diseases which need firm immobilization. The triangular splint method has merits, such as spontaneous reduction by the fractured arm weight with gravity, the stability during care, relatively comfort during procedure. Satisfactory results had been obtained by the triangular splint method.

Primary pericardial tumors are rare than those originating within the myocardium or endocardium and, moreover, primary benign pericardial tumors are much rare in occurrence. Fine(1986) was able to collect only 43 cases of lipoma. Most cases are diagnosed only at autopsy. One fourth of the cardiac lipoma arise subepicardially, where they suggest the presence of pericardial effusion with compression or displacement of the heart. A case of primary intrapericardial lipoma simulating pericardial effusion is presented. This tumor originated in left anterior aspect of pericardium. The tumor was measured 30x30x5cm in size and 2,200mg in weight. Total excision of the mass was accomplished by posterior lateral thoracotomy incision, resulting in complete cure. This is the first case of primary benign lipoma of the pericardium in literatures in our knowledge.

The cause of radiolucent filling defects in the upper urinary tract are malignant tumor, radiolucent stones, blood clots, air bubbles, congenital deformities of renal parenchyme, and various specific and non-specific infection and their sequence. So the differential diagnosis between malignancy and radiolucent stones is very important, and the exact and fast diagnosis of radiolucent stones is useful in excluding the possibility of malignancy. 27 cases with radiolucent stones were evaluated retrospectively for exact diagnosis and appropriate treatment method. Intravenous urography was done in all cases, and retrograde pyelography, ultrasonography, computed tomography and/or ureterorenoscopy were performed for diagnosis, if needed. Size of stones were measured below 10mm by transverse length in 19 cases (70.4%) with a range of 3 to30mm. The locations of stones were pelvocalyceal system in 8 cases (29.6%) and ureter in 19 cases (70.4%). Among the diagnostic methods, computed tomography was used most frequently. ESWL with retrograde pyelography was most frequent used method of treatment, also simple hydration to small stone was effective.

All ceramic restorations have had a more limited life expectancy than metal ceramic crowns because of their lower strength. The relatively lower strength has limited the use of all-ceramic crowns to the areas where occlusal loads are lower. Therefore many researches have been done to increase the strength of all-ceramic crowns. IPS Empress 2 is a new type of lithium disilicate glass-ceramic with enhanced physical characteristics which has been in use clinically since 1998. Previous researches reported that the flexural strength of all-ceramic material was greater than 300MPa, and all-ceramic crowns can be used in staining or layering technique. The objective of this study was to investigate the influence of the thickness of IPS Empress 2 ceramic on fracture strength. Both staining technique and layering technique was investigated. Vita VMK was used as control. For all three groups, five specimens each of 0.8mm, 1.0mm, 1.4mm, 1.8mm, and 2.2mm thickness (a total of 75 specimens) were prepared. Control group: Vita VMK Porcelain specimens were prepared with dentine ceramic and liquid glazing was done. Group I: IPS Empress 2 were prepared with staining technique and stained twice and glazed once. Group II : IPS Empress 2 were prepared with layering technique and glazed after wash firing. The thickness and diameter of the specimen were measured and controlled after specimen preparation. Biaxial Flexure Test (ASTM Standard F394-78) was adopted as this test method produces results least affected by the edge condition of the specimens. Fracture strength was measured with Instron Universal Testing Machine. Conclusions are as follow : 1. The fracture strength was increase in order of control group, test group I, test group II. 2. Fracture strength of the group I(Empress 2 Staining) was 65.54 N in 0.8mm, 155.2 N in 1.0mm, 233.5 N in 1.44mm, 434.5 N in 1.8mm, and 600.1 N in 2.2mm. 3. Fracture strength of the group II (Empress 2 Layering) was 190.0 N in 0.8mm, 283.5 N in 1.0mm, 437.2 N in 1.4mm, 732.0 N in 1.8mm, and 1115.0 N in 2.2mm. 4. No statistical difference was found in flexural strengths according to thickness in a specified group(p>0.05).
