Treatment of infected nonunions of long bone is confronted with various difficult problem, e.g. eradication of infection and osseous union even in the presence of devastating infection. To solve this problem various method were proved including exerternal fixation, electrical stimulation and functional casting method with some success. Intreating these difficult infected nonunions, we adopted another program which includes through debridment of the infected and necrotic soft tissue and bone, autogenous bone graft, rigid internal fixation of fragments and ope.n drainage of the wound until union of the fracture. We treated 8 cases of infected nonunions with this method from march, 1980 to september 1983 and results are as follows: 1. Satisfactory union was obtained within average 5 months. 2. In some cases pus drainage continued even after osseous union but it was easily controlled after removal of fixation devices. 3. After bone union and removal of internal fixation devices, some kind of protective measures, e.g. crutches and braces were used for about 6 montes to prevent refracture. 4. In conclusion our method is considered to be an effctive means is treating infected nonunion of fractures.

Forearm bone fracture is a common injury in childhood. But there are many difficult problem to solve in treatment of the forearm bone fractures which are not encountered in the treatment of fracture of the other long bone. Forearm bone fracture in children differ from those in adult in a number of ways. The rapidity of healing, fuctional recovery together with the frequency of delayed or nonunion consitute the main features. More interesting, a deformity resulting from malunion may correct as bone growth proceeds. From August, 1973 to July, 1983, we have reviewed 66 cases of forearm bone fractures under 14 year old and which were treated in the Department of Orthopedic Surgery, Hanyang University Hospital. The results were as follows: 1. 56 cases(84.8%) were male and most cases occured in school age. 2. 40 cases(60.7%) were both forearm bone fractures and most common site of the fracture was the distal 1/3 3. The most common cause of the fractures was falling from height. Simple fracture was most common and greenstick fracture was next. Closed fractures were 61 cases (92.4%) and open fractures were 5 cases (7.6%) . 4. In roentgenologically, the younger the child was, the more rapid the duration of bone union was. Average duration of roentgenological union in conservative group was 8. 1 weeks, and that in operative group was 10. 1 weeks. So conservative group was more rapid in roentgenological bone union than operative group. 5. Accarding to the follow study of remodelling, the young the child and the nearer the fracture line was to the epiphyseal plate, the greater the potentialities for spontaneous correction were. 6. 62 cases (94.0%) showed excellent fuctionat result. According to 4 cases (6.0%) which showed good fuctional result, posterior angulation 17 degree, anterior angulation 15 degree and medial angulation 17 degree after reduction became more than 10 degree after remodelling.

Magnetic resonance imaging(MRI) is clearly more reliable than computer tomography and myelography in radiological diagnosis of lumbar herniated intervertebral disc. Moreover, MRI can also detect degenerative changes of intervertebral discs. The purpose of this study was to determine the utility and accuracy of MRI in conjuntion with the diagnosis of lumbar herniated intervertebral disc and to compare findings with operative findings. Comparisons of operative findings and MRI were done in 133 cases. Each patients had been diagnosed by MRI as having lumbar herniated intervertebral disc. MRI findings included those of spin echo T1-weighted images and T2-weighted images, gradient echo T1-weighted images and T2-weighted images, and gadolinium-DTPA enhancement when needed. In 32 protrusion disc cases diagnosed by MRI, 28 cases were confirmed by operation and four were actually extrusion disc. In 77 cases diagnosed by MRI as extrusion disc, 72 cases were confirmed by operative findings, while 5 cases were found to be protrusion disc. 4 cases of sequestration disc diagnosed by MRI were confirmed by operative findings. Specific dimensions of MRI use yielded the following results: protrusion disc indicated 84.8% in sensitivity, 95% specificity, 87.5% in accuracy; extrusion disc showed 94.7%, 86.5%, 93.5%, respectively; and sequestration disc revealed 100% in all categories. In this study, the average accuracy of lumbar herniated intervertebral disc diagnosed by MRI was 93.6% on average. Accordingly, MRI has shown itself to be a good diagnostic tool for determining anatomical and biological change in lumbar herniated intervertebral disc.

Active infective endocarditis, involving native, is often complicated by conduction abnormalities. These conduction disturbances are considered to represent an extension of the infection from the valve to the annulus, and to the surrounding myocardium. We describe a case of a 59-year-old woman who presented with dyspnea due to staphylococcal endocarditis, which was complicated by a complete heart block.

The purpose of this study was to compare the marginal fit of provisional restorations by differentiating the removal time and setting temperature during resin polymerization. After mixing autopolymerizing methyl metharcrylate resin, the material was placed in a preformed resin shell crown. The crown was seated on a die with 1mm shoulder margin. Crowns were removed after 3,4,5,6 minutes and polymerization was continued under the following conditions : 25degrees C air,30degrees C, 40degrees C, 50degrees C,60degrees C,70degrees C water. After polymerization, the crown was sectioned. The marginal & occlusal discrepancies were measured. The mean marginal discrelpancies at 3 minutes, 4 minutes, 5 minutes and 6 minutes of removing time were 96.6micrometer,84.6micrometer, 86.7micrometer and 105.6micrometer.The mean occlusal discrepancies at 3 minutes, 4 minutes, 5 minutes and 6 minutes of removing time were 106.7micrometer, 89.3micrometer, 98.6micrometer and 127.7micrometer.There was significant difference between 4 minutes group and 6 minutes group in occlusal discrepancies. The mean marginal & occlusal discrepancies for crowns polymerized in 25degrees C air were 98.2micrometer and 124.1micrometer. The crowns polymerized in 50degrees C water demonstrated the smallest marginal & occlusal discrepancies. The mean value of marginal & occlusal discrepancies in 50degrees C water were 73.1micrometer and 77.5micrometer. These values were smaller than that of 25degrees C air.There were significant differences in the occlusal discrepancies between 25degrees C air and water conditions of 50degrees C water (alpha=0.05) but, no significant differences in marginal discrepancies. There was no significant difference in the interaction between time and temperature. 4 minutes waiting time & 50degrees C water polymerizing condition produces the best fit at the margin of the provisional crown.

Anti-thrombin III deficiency is known as a disease of autosomal dominant trait and relatively common, but in Korea, exact incidence and mortality is not known, In general, Anti-thrombin III deficiency is expressed to venous thromboembolism like deep vein thrombosis or pulmonary embolism. But, arterial embolism is very rare. We experienced a case of Antithrombin III deficiency expressed as myocardial infarction of inferior wall by huge thrombosis in the mid and distal right coronary artery.

PURPOSE: Up to now, there are several controversies in many aspects of osteochondritis dissecans. In this paper, we have intended to evaluate the frequent location and the etiology of the osteochondritis dis-secans of the femoral condyles, and to assess the adequate modality of operative treatment and its results according to the modality. MATERIALS AND METHODS: We reviewed retrospectively forty-four knees in forty patients. We analysed their clinical and radiological finding to take the incidence at both condyles and its etiology and to estab-lish the modality of applied operative methods according to the status of the lesion. The performed operative methods were multiple drilling(1 case), fragment fixation(2 cases), curettage & multiple drilling(36 cases), osteochondral autotransplantation(5 cases). The majority of these operation was proceeded under arthroscopy. Its clinical results were assessed by Aichroth's result grading system after an average follow-up of two-years and eleven months(range, one year and two months to six years and one month). RESULTS: Twenty one cases were medial femoral condylar lesions, and 23 cases were lateral. 91% patients had had the history of the definitive trauma(20 cases) or the minor repetitive trauma in their envi-ronments(20 cases). After operative treatment, seven knees had an excellent result; twenty-nine, a good result; six, a moderate result; and two, a poor result. Satisfactory result was 82%. CONCLUSIONS: On the basis of this review, we suggest that there is no difference in incidence between both femoral condyles, and that the trauma is seemed to play a major role as an etiologic factor. Majority of operated patients showed satisfactory results after application of our treatment modality.

Foreign bodies in the maxillofacial area are not commonly seen. If occurred, the immediate removal of foreign bodies is recommended to avoid further complications. The most important thing is a exact localization of foreign bodies using X-rays such as plain radiography, computed tomography, magnetic resonance imaging and ultrasound before treatment. During removal of foreign bodies, tissue should be dissected carefully and complete exploration of the whole wound required.
