Insall-Burstein Posterior stabilized knee prosthesis is a variant of total condylar prosthesis. It is designed to get more wide range of flexion and stability with the transverse cam. We analyze with modified HSS knee rating score clinically and scoring system of AKS(American Knee Society) radiologically. We report the operative results in 34 cases of 25 patients whom we operated with Insall-Burstein PSP from August, 1982 to May, 1985 and the long term follow-up result of 24 cases of 16 patients, excluding three death and 7 cases of 6 patients who were lost to follow up. Follow-up period is average 11 years and 5 months. The average preoperative flexion contracture improved markedly. The average preoperative flexion arc was 95° and preoperative flexion contracture was 14°. The postoperative ROM and flexion contracture improved markedly. The average preoperative modified HSS knee rating scoring was 52 points and improved to 91 points at last follow-up. Patients with rheumatoid arthritis had progression of other joints involvement which limited the activity of daily living. At the last follow up, loosening signs were not observed radiologically but three cases of radiolucent zone were observed in the zone I, II, III, IV, VII of tibial components and zone III, VI of femoral components. There were two deep infections.

One hundred and thirty one health articles (as "original articles") reported in medical journals published in Korea during the period form Jan. to Dec. 1971. were selected as the study materials for the purpose of resumption and criticism. Of a total of 131 articles, thirty-nine were not required the statistical application for the data processing and drawing their conclusions and ninety-two, 70.2%, were needed to apply. The 92 articles were divided into three groups by the types of study: 54 for experimental study. 30 for clinical case analytic study and 8 for field study. Each report was resumed and criticised under the statistical aspects in terms of data processing and the validity of the conclusions. The results of resumption of the 92 articles needed statistical application are summarized as follow ; 1. Of the 54 articles of experimental studies resumed, thirty-one articles, 57.4% were considered acceptable. Among the 38 articles classified as clinical case analytic and field studies, only 28.9 per cent were considered acceptable. In total 45.7 per cent or less than half were considered acceptable. 2. Types of errors encountered are as shown in Table 3. 3. The most frequently encountered error was that the conclusions were drawn without having made any statistical test. This type of error was found in 14 out of 35 errors presented in experimental studies, 11 of 35 in clinical case analytic studies and 5 of 9 in field studies and 30 out of 97, 38.2%, in total.

We investigated the cold reaction of fingers in cold water as a criterion of peripheral resistance to frostbite in order to obtain elementary data to improve farmers' health. Experiments were carried out on 81 farmers and 64 urbanites at 20±2°C, 55±5% RH with sitting position on the floor. The finger skin temperatures of the subjects were measured while the left middle finger of each subject was immersed in cold water or 0°C for 30 minutes and recorded once every one minute with the thermistor. We also compiled statistics on the following items: mean finger skin temperature (MST), finger skin temperature at initial rising after immersion (TFR), time for the appearance of initial rising after immersion (TTR), cold resistance index (RI), etc. The results were as follows RI was higher in farmers than in urbanites, but there was no significant difference between the two groups. In men, RI was lower in farmers than in urbanites, but there was no significant difference between the two groups. By contrast, in women, TFR and RI were significantly higher in farmers than in urbanites. MST was significantly higer in women than in men, but RI was no statistically significant difference. By age, the men in their 30's showed significantly the highest MST and the shortest TFR. RI was significantly higher in the men in their 30's than others. In women, however, the difference in RI was of no statistical significance. By region, MST was the highest in Seoul dwellers. RI was the highest in Okku dwellers, but there was no statistically significant difference among regions.
These results indicated that farmers tended to be higher than urbanites in cold resistance index.

BACKGROUND: As modern epidemiologic studies began to identify obesity as a risk factor for cardiovascular disease, diabetes, hypertension, and cancer, measuring the degree of excess body fat is important on epidemiologic surveys. The evaluation of obesity level in epidemiologic surveys has been mostly done indirectly by measuring patient's height and weight. But, the anthropometry could not be done to respondents of recalling past anthropometric values or to proxy respondents. This study was attempted to elucidate usefulness of a somatotype drawing as a measuring instrument of obesity level in epidemiologic surveys in Korea. METHOD: The inclusion criteria of subjects were (1) members of the Seoul Cohort Study, who were recruited by self-administered structured questionnaire survey through mailing to the healthy men between the ages of 40 and 59 years through the program of a biennial health checkup offered by the Korean Medical Insurance Corporation (KMIC), and (2) volunteers for cancer screening program offered by KMIC. For assessing usefulness of the instrument, measurement of status/weight and self-administered questionnaire survey were done separately through the program of a biennial health checkup and of cancer screening. RESULTS: The data were collected from 138 subjects, whose Body Mass Index (kg/M2) was 23.58+/-1.46 (mean+/-SD). When the validity was measured through correlation with BMI, Spearman's correlation coefficient (rs) was 0.72 (p<0.05), that remained statistically significant after adjusting age, education level, and monthly income and occupation. And, the grades of somatotypo drawing were grouped as 1-3, 4-6, 7-8 by ANOVA and Tukey test. CONCLUSIONS: Instrument using somatotype drawing is applicable to screen degree of body fat in self-administered questionnaire surveys in Korea.

The frequency of the patellar fracture is increasing because of increasing traffic accident & sports activities and its treatment is considered very important because the involvement of the articular surface occurs in most of it. The authors experienced 54 cases of patellar fracture from January, 1979 to October, 1980 at the Department of Orthopedic surgery, Capital Armed Forces General Hospital and the results were as follows. 1. The most fractures were encountered in man of 3rd. decade. 2. Thirty-eight (70.4%) fracture were induced by direct blow and the remainders were induced by indirect violence. 3. The most fractures were stellate, communited fractures (44.4%) and transverse fractures (37%) which mostly occured at the middle portion. 4. The most fractures were treated by conservative method, circumferential wiring, tension band technique and patellectomy, and the result of the tension band technique was superior to other operative methods (shorter immobilization time, rehabilitation time, and wide range of motion of the knee joint and longer midthigh circumference). 5. The rehabilitation period was shorter in the group of immobilization in 10° flexion of knee with cylinder cast than in the group of immobilization in full extension of knee. 6. Skin lacerations, femoral fractures, and tibial fractures were associated injuries, and the superficial infections and peroneal nerve palsy were complicated.
