This is a statistical observation based on data of deaths occurred in the first army group(1A) of Republic of Korea Army (ROKA) and data brought to Wonju Army Hospital for medicolegal autopsy by all of Military Police Corps (MPC) in 1A during the year of 1996. The report aims to reveal facts on various causes of death of military members in attempt to analyse 70 cases statistically and differences between military members and civillians. The following are the summary of results ; 1. The total numbers of death in 1A were 70 cases and autopsy rate was 17.1%(12 cases). All cases were males. 2. The violent deaths were 60 cases(85.7%) and the natural deaths were 10 cases(14.3%). 3. The percentage of deaths of soldiers was 81.4%(the most), sergeants was 8.6%, officers was 5.7%, others was 4.3%. The group of the private (25.7%) and the private first class (25.7%) was the leading group of death by the rank. 4. For deaths due to injuries, the percentage of deaths due to gunshut injury was 51.2%, traffic accident was 30.1%, explosion of bomb was 7.0%, fall was 7.0% and blunt injury was 4.7%. 6. For the natural deaths, 10 cases were recorded and death due to neoplasm was taking the most of the total percentage with 40%. 7. For the violent deaths, the percentage of accidental death was 42.4%, suicide was 40.7% and homicide was 16.9%. These results suggest that suicide by firearm and traffic accident including military owned vehicle could be the major cause of death in army, and intensive management for group of the private and the private first class could be important to reduce the number of death.

Limb salvage operation in primary malignant bone tumors is increasing recently, according to the improvement of diagnostic methods, surgical technique and adjuvant chemotherapy. The purpose of this study is to obtain the interim results of survival rate and the functional grade of the limb in primary malignant bone tumors treated by limb salvage operation. Between 1985 to 1993, 63 primary malignant bone tumors treated by limb salvage operations. Tumor prosthesis arthroplasty was performed in 49 patients, resection arthrodesis in 9 patients, and IM nailing with cement molding in 5 patients. Autoclave autograft was combined in 2 patients. Adjuvant chemotherapy and postoperative radiotherapy were performed in selected patients. The average follow-up period was 50 months(ranged 12 months to 116 months). In the cases of osteosarcoma, estimated survival rate was 61.9% based on Kaplan-Meier survival plot. In the parosteal sarcoma, the survival rate was 87.5% and 80% in chondrosarcoma patients. According to functional grading by Enneking, 66% was excellent, 20% was good, 11% was fair and one patients was poor. Complications occurred in 16 patients:wound infection was developed in 6 patients, local recurrence in 4, peroneal nerve palsy in 2 patients and femoral stem loosening in 2 patients. Fracture in resection arthrodesis and pulmonary metastasis were also occurred. Reoperation was performed in 10 patients at average 31 months after initial operation. Revision tumor persthesis arthroplasty was performed in one patient due to local recurrence and in 2 patients due to femoral stem loosening. Three amputations were done due to recurrence of tumor. IM nailing with cement molding was performed in one patient due to deep infection and repeated arthrodesis was done in a fracture patients. Scheduled custom-made tumor prosthesis arthroplasty was performed within a year in 2 patients treated with IM nailing with cement molding. In conclusion, with the careful preoperative assessment, adjuvant chemotherapy and skillful surgical technique, limb salvage operation would provide the primary malignant bone tumor patients for longer survival and better quality of life.

Simple bone cyst was first described by Virchow over a century ago and has been the subject of numerous articles. Nevertheless considerable confusion still exists regarding its etiology. clinical behavior and optimal management. Eighteen cases of pathologically proven simple bone cyst were treated in the Department of Orthopedic Surgery, Seoul National University Hospital during the thirteen year period from June 1966 to May 1979, and following results were obtained. 1. Age distributions were between five and forty-three years (Average ; seventeen years), and 72.2% (thirteen cases) were during first two decades of life. 2. Male to female ratio was 2.6 to 1 3. The most frequently involved location was proximal humerus followed by proximal femur. 4. Pathologic fracture, pain, incidental roentgenography and swelling were the first clues of diagnosis in our series. 5. In twelve cases curettage and fresh autogenous iliac bone graft was performed and good results were obtained in all of them. Of five cases only curettage had been done, no case recurred, another case showed residual cystic area, and the rest healed without further event. In one case with huge cyst curettage, iliac and fibular bone graft and bone cementing was performed with satisfactory result. 6. Bone shortening was noticed in two cases of active bone cysts in proximal humerus 2cm and 3cm, respectively.

Although osteltis fibrosa cystica was the clinical manifestation originally recognized as a feature of the primary hyperparathyroidism, its frequency in diagnosed cases currently has decreased. Affected patients are now being detected in earlier stages of the disease. We have experienced a case of primary hyperparathyroldism with the typical bony changes and the pathologic, subtrochanteric fracture of left femur. We have treated the fracture with Zickel nalling and parathyroidectomy was performed. Four months after the removal of parathyoid adenoma the fractured femur healed well.

Recently there has been remarkable improvement in the treatment of chondrosarcoma, accompanied with the development of diagnostic tools, operative technique, replacement materials and designs, anticancer-chemotherapy and radiotherapy. In well-deferentiated chondrosarcom, wide excision is the only treatment required. Nevertheless, in dedifferentiated chondrosarcoma, anticancerchemotherapy or radiotherapy is usually recommended after the wide excision. From 1984 to 1994, 22 patients diagnosed as chondrosarcoma had been treated at Seoul National University Hospital. We analysed anatomic distributions, size, methods of treatment and their results. The avereage age was 38 years and 10 months(15 years 73 years) and the average follow-up period was 3 years and 10 months(1 year and 6 months

To pursue a desirable format for the pathological diagnosis of liver cirrhosis, the authors attempted to classify 369 biopsy-proven cirrhosis on the basis of etiology and made effort to find out the morphological characteristics of each category. About 735 of total cases were HBsAg seropositive postnecrotic cirrhosis. Alcholic cirrhosis ws the second most frequent type, although accounted only 6.8%. In about 15%, the etiology was not known. Excluding the congenital biliary atresia, chronic biliary obstruction appeared to be a rare cause of cirrhosis among these biopsied cases. Of the HBsAg positive postnecrotic cirrhosis, the eAg seropositive cases tended to be micronodular and to show a higher necroinflammatory activity, in contrast to eAg seronegative cases and those complicated by hepatocellular carcinoma (HCC), suggesting that the loss of eAg is followed by a decrease of the destructive activity, active regeneration of hepatocytes and finally the development of HCC. alcoholic cirrhosis was micronodular in 64% and revealed histologic evidences of alcoholic liver disease in most cases. The results indicate that etiological diagnosis can be made in most cases of cirrhosis by the morphological characteristics and the precise clinical informations, including those on the NANB virus and the inborn error of metabolism, and that the pathological diagnosis should be more comprehensive, implicating the etiology, the nodular size and the necroinflammatory activity.
