PURPOSE: This study was performed to find out whether tibial bone defect preceeding the surgery has an effect on the outcome of patients who have undergone total knee replacement therapy with an evaluation period of more than five years. MATERIAL AND METHOD: Osteoarthritis patients who were treated with total knee replacement and evaluated for more than 5 years were selected, of which 42 patients were with tibial bone defects, and 21 without. Clinical evaluation were made on the basis of pre- and post-operative Knee Society Knee Score and Functional Score, radiological evaluation using the American Knee Society Score. and range of motion, tibio-femoral angle, subjective satisfaction, complication were evaluated. RESULTS: Knee fuction score and subjective satisfaction of the two groups showed significant improvement after the surgery, but comparison between the two was statistically insignificant. Radiological evaluation showed radiolucency in zone 1 and 2 of tibia in the majority of both groups, but dissociation of the inserted device was not shown. CONCLUSION: In the cases of tibial bone defect, bone cement, screw fixation enforced with autograft, and wedge metal insertions can be considered to be effective in treating patients by total knee replacement surgery.

This study was carried out to analyse the food intake and associated factors of the urban poor elderly by comparing poor district, Unbong rental apartment in Bonsong 2 dong with other areas in Pusan. 135 elderlies(men 36, women 99) in Unbong rental apartment 136 elderlies(men 45, women 91 ) in the other areas were investigated during the period of March to August in l994. The assumption that the study area represented poor district was satisfied because the age and sex distribution was not significantly different, and the income of the study area was significantly lower than that of the control area. The variables of hospitalized in previous 12 month, gastrointestinal problem, alcohol drinking, cigarette smoking did not differ significantly. But the variables of chronic disease, take medicine, perceive, vitamin supplement differed significantly between two groups. Therefore some factors associated with health state in the study area are worse than those of the control areas. At most of all variables, nutrients intake of the study area did not reach the recommended dietary allowances(RDA) for Koreans, and that nutrient intakes of the study area were significantly lower than those of the control area. The hypothesis of this study that nutrient status depends on economical status was proved. As for the score of nutritional knowledge, the study area was significantly lower than the control area. But as for the score of nutritional behavior, two areas were not significantly different. The latter is counter result of our hypothesis, owing to the effect of the confounding factors including education etc. As for the correlation of variables, not only economic status and educational level, but the score of nutritional knowledge effects strongly on nutrient status in the study area, the poor district. Therefore, adequate nutritional education to the elderly in the poor district should be considered.

This survey was performed to obtain the basic information for the prevention and management of occupational low back injury(LBI). The subjects of this survey were 952 workers(male, 892;female, 60) who had taken occupational LBI in some industries of Pusan area from January 1 to December 31, 1991. Observation period was 2.6 years from the beginning to the end of medical treatment. The obtained results were summarized as follows; 1. The proportion of LBI workers was 15.9% of the workers who had taken any occupational injuries and 0.32% of all workers in this surveyed area. 2. 8.0% of the workers had taken LBI on the 1st day of employment and 55.2% of the workers were within one year, 91.4% of the workers were within 10 years according to cumulative frequency distribution. 3. Handling of heavy objects was the most common cause of LBI(32.0%) and fall down(26.9%) and slip down(16.3%) were the next in order. 4. The most common causes of both lumbar sprain and HNP were handling of heavy objects and that of lumbar fracture was fall down. 5. The mean duration for medical treatment of LBI workers was 143 days. 6. The total direct compensation cost for LBI workers was 6,736 million Won and the proportion of medical, resting, disability compensation costs were 25.0%, 37.0%, 38.0% respectively. 7. The percentages of retreated workers and disabled workers were 11.9%(113 persons) and 22.9%(218 persons) of total LBI workers respectively.
