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.

To evaluate the effect of a new topical anesthetic cream (EMLA : Eutectic mixture of local anesthetics) on reducing pain associated with DPT vaccination, we conducted a clinical observation on eighty infants who were brought to well baby clinic of Yeungnam University Hospital for DPT vaccination. 80 Infants, who were between 2 months and 8 months in age, were divided into two groups. EMLA treated group and control group. Male to femle sex ratio was 1.4 to 1. EMLA cream was applied 60 minutes before DPT vaccination, the effect of reducing pain was assessed by using McGrath's face scale, Oucher pain scale and modified behavioral pain scale (MBPS) and also evaluated by measuring the duration and time of crying (the time of the first crying after iniection, duration of the first crying, total duration of crying). The scores of those scales were lower in EMLA treated group than in control group significantly (P<0.01 in McGrath's face scale. MBPS and p<0.05 in Oucher pain scale). There was no difference in the time of the first crying after vaccination in both groups. The duration of the first crying was shorter in EMLA treated group than control group of crying was also shorter in EMLA treated group (EMLA treated group 9.0±12.5 sec, p<0.05). Transient skin erythema was noted in 5 infants after EMLA application, but no other adverse effects were observed. We conclude that the application of EMLA cream before vaccination seems to be an effective and safe way to reduce the pain from vaccination, but it takes usually 60 minutes to get the anesthetic effect of EMLA and it is expensive, so EMLA cream can not be recommended in routine vaccination in infants now.

Undifferentiated sarcoma of the liver is a highly malignant neoplasm that occurs almost exclusively in children. We present a case of adult undifferentiated sarcoma in a 33-year-old man. The neoplasm was typically hypovascular on hepatic angiography and a globular, cystic and mucoid mass separated from the adjacent liver by a psedocapsule was removed from the left lobe of the liver. Necrosis and hemorrhage were found. Microscopically the neoplasm consisted of myxoid and cellular areas and the basic neoplastic cells were stellate cells showing variable degree of anaplasia and pleomorphism. Eosinophilic globules were PAS-positive and immunohistochemically negative for alpha-fetoprotein. Extramedullary hematopoiesis was present and normal-appearing bile ducts and hepatic cell cords were noted.
