Congenital pseudarthroses and non-unions have been recognized as some of the most challenging problems in orthopaedic surgery. with a standard surgical procedure, such as bone grafting, nailing, plating or a combination of these, it was frequently failed to unit. After repeated surgical failures, amputation has been the main course. With the advent of an electrical control of osteogenesis, however, this dismal outlook is brightening. The earliest report of the use of electrical energy to directly stimulate bone healing seems to be in 19th century, but it was not reliable. In this century, the electrical properties of bone were first described by Yasuda et al in 1953. After then, several investigators have shown that the application of small amounts of the electrical current to bone stimulates osteogenesis at the site of the cathode. Clinical trials using various froms in the treatment of delayed union, non-union, and congenital-pseudarthrosis began early in the 1970's. Constant direct current, pulsed current, and electromagnetically induced current have all been used clinically to heal bone defects with varying degrees of success. But, to-this date it is unknown what is the mechanism of stimulating bone healiag with electricity, and which from of electricity is most efficient in stimulating osteogenesis. We have experienced direct current stimulation to promote osteogenesis in 9 cases of non-union and 4 cases of congenital pseudarthses of the tibia from august, 1978 to december, 1980. Of 9 non-unions, 7 (77.8%) achieved solid bony union. We had obtained bony union in 4cases of non-union only with the electrical stimulation. In 4 cases of congenital pseudarthses of the tibia, all cases achieved solid bony union with the electrical stimulation and bone graft, but in 3 cases, refractures were occurred. At this moment, our conclusions from this study are as followa. I. Direct current stimulation is one of the reliable methods inducing ostengenesis. 2. Regular follows-up and determination of the stimulator integrity are essential steps in the electrical stimulation. 3. Combined treatment with the electrical stimulation and bone graft have markedly improved the success rate. 4. In direct current stimulation of congenital pseudarthsis, the mechanically sound bony alignment, massive bone graft and protection using long leg brace seem to be mandatory procedures.

Zygomatic arch is a prominent structure among facial bone and this is the major cause of vulnerability from the facial trauma. The fracture of zygomatic arch has been treated by ancillary methods of closed reduction approaching through temporal incision or intraoral incision. But, these methods gas a limitation of reduction force vector and it has a difficulty in maintaining the secure fixation of the reduced unstable fractured bones. All 22 cases of zygomatic fracture were reduced by transcutaneous screw and fixed with external fixation device successfully. There was no post-operative complication, such as non union, malunion, and visible scar. This method also has advantages of less post-operative edema and pain.

Fibrous dysplasis is a condition characterized by the metastatic replacement of the medullary component of predominantly long bone with fibrous tissues. This change is responsible for the characteristic features, including bony abnormalities, pathologic fractures and pain. The monostotic form of the fibrous dysplasia occurs more freguent than the polyostotic form. The monostotic fibrous dysplasia does not exhibit the laboratory abnormality, extra-skeletal manifestation or the endocrinopathies associated writh polyostotic disease. Monostotic fibrous dysplasia occurs most frequently in the metaphysis of long bones and the ribs. Only the seven previous cases of vertebral involvement (three cervical, one thoracic, three lumbar spine) in monostotic fibrous dysplsia have been reported. Authors experienced a case of monosotic fibrous dysplasia of the seventh cervical vertebrate, so we report a case with the review of the seven previous reported cases of the monosotic fibrous dysplasia of the spine.

Finances of health insurance can be explained by factors determining benefit expense and premium collection. This study was conducted to analyze factors contributing to the financial status of rural health insurance. Nationwide 134 health insurance associations except the six pilot project counties were analyzed and obtained the followings. 1. In univariate analysis, statistically significant variables that explain 1) outpatient benefit expenditures include public health center utilization, proportion of pregnant women, premium and collection rate of premium 2) inpatient benefit expenditures include public health center utilization, proportion of old age, proportion of pregnant women, premium and collection rate of premium 3) profits include public health center utilization, proportion of old age, proportion of pregnant women and collection rate of premium. 2. In multiple regression analysis, statistically significant determinants in 1) outpatient benefit include premium and public health utilization 2) inpatient benefit include premium 3) profit include public health center utilization, premium and collection rate of premium.
