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.

In order to compare the effects of the flexible external fixations with the rigid one on fracture healing, rabbits tibiae were fractured surgically and each fracture were immobilized with external devices using graphites (the group I), plastics (the group II) and stainless steel (the group III). At six weeks after fracture, clinical and radiological union rates in group I, II and III were 91% 73% and 60% respectively. The rabbits tibiae were load in 4-point bending test to determine the mechanical properties of the fracture healing. The means and standard errors of maximum bend moment of the fractured tibiae were 11. 30±2.33kg.f. cm., 8.55±2.02kg.f. cm. and 9.79±2.09kg.f. cm. in group I, II and III respectively. These data may suggest that a certain amount of the flexibility (ex, graphite) or motion is better than the rigidity (ex, stainless steel) in fracture healing by the method of the external immobilization).

It is essential to define the accurate location and extent of bony bridge in relation to the epiphyseal plate for operation of partial epiphyseal plate closure by bony bridge resection. Since magnetic resonance imaging(MRI) provides excellent tissue contrast and multiplaner image, it could be applied to the diagnosis and mapping of bony bridge of epiphyseal plate. A thirteen year old female with post-traumatic epiphyseal injury of ankle was diagnosed by MRI. We could assess the bony bridge accurately by direct sagittal and coronal images and excellent tissue contrast of MRI.

The femur is the largest long bone in the body which is related to weight bearing. As a result of rapid increase in traffic accidents and industrial injuries, the incidence of femoral shaft fractures has risen also. The methods of treatment in children and adults are different, therefore inadequate treatment can cause permanent disability. The authors have reviewed 211 cases of femoral shaft fractures in 204 persons (children and adults) from September 1967 to September 1976 whe were admitted and treated in Orthopedic Department, Severance Hospital. The results were as follows: 1. The fractures occured commonly in the 6–10 yr. age group (41.2%) in children and in the 21–40 yr. group (54.2%) in adults. Males comprised 138 cases (67.6%). 2. Closed fractures were 185 cases (87.7%) and comminuted fractures were the most common type, 94 cases (44.5%) in all. The fracture site was middle third in 116 cases (55%). 3. Causes were mainly car accidents, 146 cases (71.5%) and industrial injuries. Pedestrian injuries are particularly common in Korea. Many industrial accidents occur due to inadequate working facilities in factories. 4. Associated injuries were common in young adults and in order of frequency these were fractures of the tibia and fibula; skulls; pubic bone. 5. In the early and delayed operation groups, primary bony union rate was better (92%) in the early than the late operation group (78.3%). 6 The period of bony union was 13 weeks with compression plate and screw fixation: 16 weeks with Kuntscher nailing; 17. 5 weeks with plate and screw fixation; and 20 weeks with skeletal traction in adults. 7. Knee joint motion was most limited with skeletal traction (33.5%), less with plate and screw fixation (14.7%) and Kuntscher nailing (1.7%), but none with compression plate and screw fixation. 8. Good results were obtained with conservative treatment in children and operative treatment in adults. 9. Complications were much less frequent in children than in adults and were treated well. 10. Post-operative infection rate was 4.4% and infection was treated well with conservative measures. 11. The 90° – 90° skeletal traction in children and compression plate and screw fixation along with cast brace in adults were recommended.

Recent development of dental implantology has taken an interest in the bone graft procedure. This is a review of literature, published from 1994 to November 1999. This study is provided by MEDLINE search. In this study, 718 patients received 829 graft with placing 2,677 endosseous implants. In mandible, nonvascularized or vascularized block bone grafts provided better results (success rate 95.2%) than particulate grafts(83.6%). But in maxilla, particulate grafts provided better results(93.7%, 86.2%) and more cases especially in sinus elevation. There were many cases using autogenous bone graft and revealed good results, but allogenic or alloplastic bone graft materials also were used by many surgeons.

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%.

Extragondal germ cell tumors are rare, which develop outside of the testes, but histologically identical to primary testicular germ cell tumors. There have been much interest and controversies about their etiology, definition, treatment and care of testes. We recently experienced a case of primary mediastinal yolk sac tumor in a 16-years-old male, who was cured by intensive chemotherapy and cytoreductive surgery. Herein we report the case with review of the literature.
