Author recently experienced four cases of Osteogensis Imperfecta belonged to fetal, infantile and tarda forms respectively. One case of fetal form exhibited severe skeletal deformities in association with multiple fractures, and died five hours after birth. Other three cases have been treated at the department by osteotomy and cast immobilization.

80 cases of Cysticercosis were studied and analysed, which were diagnoses by biopsy at Seoul National University in the past three years from January-1978 to March-1980. The results were summerized as follows. 1. The relative incidence ratio of cysticercosis among 18,941 surgical specimens was 0.42%. 2. The age group between 11 and 50 years old occupied 87.5%. 3. Of the 80 cases, there were 38 males and 42 female patients, without significant sex predominence. 4. The common sites of cysticercosis were upper extremities (35.0%) and anterior surface of the trunk (37.5%) 5. Epidemiologically, there was marked predominence of rural area over urban area. 6. There were 8 cases (10%) of definite cerebral cysticercosis and 4 cases (5%) of suspicious cerebral cysticercosis. 7. In the cases of nodular masses of extremities, the parasitic infection, especiaily cysticercosis celluiosae, must be included in differential diagnosis distinguished from other soft tissue tumors.

PURPOSE: To determine the necessity of site-specific bone mineral density(BMD) measurement and the difference between the BMD of the two femora using DXA in the evaluation of osteoporosis. MATERIALS & METHODS: Total BMD and regional BMD(Lumbar spine, femoral neck, Ward's area, intertrochanter area) were measured on seventy-eight healthy persons without previons diseases, and the statistical significance analyzed. RESULTS: Total BMD did not reliably reflect the site-specific BMD. There was a high correlation between BMD in opposing femora. Correlation coefficients between the femoral neck, Ward's area, trochanter area were 0. 939, 0.874 and 0.916 respectively. CONCLUSION: We conclude that a measuremnt of site-specific BMD is necessory because the total BMD can not reliably predict the regional BMD. The measurement of BMD in one femur can predict the BMD of the contralateral femur. If there is no history of femoral neck disease, unilateral BMD measurement is recommended for femoral evaluation.

Intraspinal tumors in children are of especially interest to orthopaedic surgeons for two reasons; First, musculoskeletal abnormalities, are often treated for long periods before the correct diagnosls is suspected; Second, important orthopaedic problems are encountered in almost everychild treated for intraspinal tumor, not only during the immediate postoperative management but all through subsequent growth. We report a case presentation of the intraspinai tumor, dermoid cyst, successfully treated with operation.

An anatomical reduction and maintainance of articular fracture is on of the basic principles In Orthopedic Surgery if good function is to ensue, especially in a major welght bearing joint such as hip knee ankle. In displaced articular fractures, excellent results can be achieved mainly by an open anatomical reduction and firm internal fixation. We performed an open reduction and internal flxation with plates and screws in a patient with the severely comminuted acetabular fracture, and a satisfactory result is obtained.

Fractures of the hip are usually classified first according to their anatomic location. Isolated fractures of the lesser or greater trochanter are not common and rarely requir surgery, Femoral neck fractures, intertrochanteric fractures, and subtrochanteric fractures are common categories that usually require open reduction and internal fixation. These fractures most often occur in elderly patients. The prognosis of these three major categories of hip fractures seems to be entirely different because of their anatomic characteristics. Seventy three cases of hip fractures were experienced at the Department of Orthopedic Surgery, Eul-Ji General Hospital over the period from Jan. 1975 to Aug. 1980 and the following results were obtained. 1. Of the 73 hip fractures, femoral neck fractures were 28 cases (38.5%), intertrochanteric fractures were 23 cases (31.5%), subtrochanteric fractures 11 cases (15%), and acetabular, fractures 11 cases (15%). 2. Traffic accident was the major cause of hip fractures in our series. 42 cases (57.2%) were caused by traffic accident, whereas 27 cases (37.0%) by a fall from the height. 3. Hip fractures occured most frequently in the age group from 31 to 50 years (53.5%). Male to female ratio was 2:1. 4. Cases caused by traffic accident visited hospital earlier than the others. 5. The most common type was Garden's type IV (53.6%) in the femoral neck fractures, Boyd-Griffins type Il (47.8%) in the intertrochanteric fractures, and Fielding's type II (54.5%) in the subtrochanteric fractures. 6. Metal devices used to fix hip fractures were Knowles pin, Jewett nail plate, compression hip screw, plate and screws, and Kuntscher nail. Internal fixation was done anatomical reduction has been achieved in stable fractures, and Dimon-Hughston reduction in unstable fractures. 7. Postoperative cast immobillzation was performed in 13 cases of 21 femoral neck fractures, 15 cases of 22 intertrochanteric fractures and 6 cases of 11 subtrochanteric fractures. The average duration of immobilization was 10 to 12 weeks. 8. Incidence of avascular necrosis in femoral neck fractures was 16.7%, nonunion in intertrochanteric fractures was 11.8%, and nonunion is subtrochanteric fractures was 12.5%.

PURPOSE: In order to compare stone metabolic risk factors in recurrent stone formers, we researched lithogenic factors according to sex and age. MATERIALS AND METHODS: We performed stone metabolic studies on recurrent stone formers (77 men, 33 women) and grouped them according to age; under 40 (n=38), from 40 to 59 (n=56) and over 60 (n=16). We evaluated excretion rate differences of lithogenic and inhibitory constituents such as volume, sodium, uric acid, calcium, oxalate, and citrate from 24-hour urine samples, and calcium, sodium, uric acid, phosphate, potassium, and chloride from serum samples. We analyzed the incidence of stone metabolic risk factors between the age groups and the sexes. RESULTS: The most common detectable risk factor in all groups of recurrent stone formers was hypocitraturia. This finding was more remarkable in males aged under 60. The incidence of hypocitraturia was higher in males and in the younger group, whereas hypercalciuria was more frequent in the elder group. CONCLUSIONS: The most important cause of urolithiasis was hypocitraturia in recurrent stone formers, and this was apparent in males aged under 60.

BACKGROUND: Chronic cutaneous lupus erythematosus(CCLE) is a well-known disease entity. But there has been no data about its clinical behavior and histopathologic features in Korea. OBJECTIVES: This study was conducted to elucidate the clinical, laboratory, and histopathologic features of CCLE, and the relationship between CCLE and SLE. MATERIALS AND METHODS: We investigated 48 cases of CCLE that visited the department of dermatology at the Seoul National University Hospital from January 1990 to June 1997. Medical records and biopsy slides were reviewed.
