Certain motion in the sports of volleyball can cause injury. For examples, excessive spiking, jumping, receiving and rolling may produce strain, sprain and stress fracture, etc. of all extremities and spine. The authors analized injuries of 160 Korean young women volleyball players treated and managed at Department of Orthopedic Surgery, National Police Hospital from September, 1973 to October, 1977. The results were as followings: 1. Of 160 cases, age distribution was ranged from 15 to 26 years and average was 20. 7 years. 2. Out of 495 injuries, 113 (23%) were upper extremities, 93 (19%) were lumbar and lumbosacral regions and 289(58%) were lower extremities. The most common site of injury was knee joint. 3. As to the ratio of the side, in the upper extremities 77% were in the right side and 23% in the left, but in the lower extremities both sides were nearly equal. 4. The injuries were composed of strain, sprain and the others, including stress fracture in 14, linear fracture of patella in 2, chip fracture of ulnar styloid process in 4, H.I.V.D. in 4 and meniscus tear in 6, etc.. 5. The injuries were supposed to be prevalent for the first one month after change from one to another team (14%). 6. The injury was usually more frequent in incidence among the exercise in winter and the heating in Gymnasium also one of the important factors to induce the injury, the injuries were less frequent at the good heating (40%). 7. It was concluded that the career of play did not affect significantly to incidence of the injury.

One of various decompression methods in treatment of spinal stenosis is the indirect instrumental decompression. Theoretically, the distraction of the disc space can widen the intervertebral foramen of the stenotic segment and even increase the canal diameter by distracting the posterior annulus as well as reduce the extent of decompressive laminectomy site. The indirect instrumental decompression, however, was not guaranteed to maintain the restored discal height because of the loss of fixation strength between rod and screw, viscoelasticity of vertebra itself, bone density, type of screw and rod, and operative technique. As well the magnitude of the stresses on the instrumentation particularly at the rod-screw interface may depend on rod-contouring in order to make mormal sagittal curvature of the lumbar spines. Therefore, the aim of this experimental study was to evaluate the effect of different rod-contour on the axial sliding strength in Compact Cotrel-Dubousset (CCD) instrumentation. Axial sliding strength was tested by Universal Test Machine (Instron). Test was performed for 3 groups of different rodcontouring on the biomechanical axial strength: straight rod (no contour), 10 and 20 contouring rod. The length of contact surface between rod and screw was measured with Fuji pressure sensitive film. The study was performed using 6.5 mm open body screws and 7 mm rods of CCD instrumentation. Axial sliding strength of straight rod was 2518.6N, 1871.8N in 10 and 1528.8N in 20 contouring rod. The length of contact surface between rod and screw significantly decreased according to degree of rod contouring; 9.88mm in straight rod, 9.08mm in 10 and 8.57mm in 20 contouring rod. There was a statistically significant linear correlation (R=0.96) between failure load and length of contact surface. Therefore, this study has shown that excessive contour of the rod in order to make normal sagittal curvature of the lumbar spine using CCD instrumentation cannot provide sufficient axial sliding strength. That may be a cause of loss of restored disc space height after surgery.

In the treatment of malleolar fracture, anatomical reduction and rigid internal fixation are essential to prevent the complications such as infection, malunion or nonunion, traumatic arthritis, skin necrosis and joint contracture. But it is often difficult to obtain rigid fixation for medial malleolar fracture because of its comminution or thin cortex with osteoporosis. Generally, two operative methods are available for medial malleolar fracture, which are malleolar lag screw fixation and tension band wiring. The purpose of this paper is to analyze which operative method is better for anatomical reduction and rigid fixation and has less postoperative complications for medial malleolar fractures. From March 1992 through March 1995, 88 patients had undergone surgical intervention for medial malleolar fractures. The patients were divided into 2 groups according to operative method for medial malleolar fracture. For one group, malleolar lag screw together with or without a K-wire was used in 48 patients, and for the other group, tension band wiring was used in 40 patients. The average follow-up periods were 14 months in screw fixation group and 13 months in tension band wiring group. The average union time were 15.4 weeks (8-17 weeks) in screw fixation group and 12.2 weeks (6-15 weeks) in tension band wiring group. 27 cases (56%) showed excellent result in screw fixation group and 30 cases (75%) in tension band wiring group. In the patient over 50 years old, 2 (15%) in 13 cases showed excellent result of screw fixation group, while 5 (45%) in 11 cases of tension band wiring group. We concluded that tension band wiring is a better method for medial malleolar fracture to obtain early union and to prevent postoperative complications, especially in the elderly patient.

We report on a first case of bone marrow metastasis by dedifferentiated liposarcoma. A 39-year-old male diagnosed with retroperitoneal dedifferentiated liposarcoma underwent surgery and postoperative radiotherapy. In spite of radiotherapy, his whole-body positron emission tomography showed high uptake in multiple bone metastasis. With thrombocytopenia, bone scan suggested bone marrow involvement. After bone marrow biopsy, bone marrow metastasis by dedifferentiated liposarcoma was finally confirmed. He was administered with systemic chemotherapy with doxorubicin. But he died 3 months after chemotherapy due to disease progression. This case revealed that in a patient of unexplained cytopenia with dedifferentiated liposarcoma, bone marrow metastasis should be in consideration.

To identify the drug abuse status and its determinant factors in high school boys in Taegu, the study was performed from April to May, 1995. Study population were selected by cluster sampling method and total 5,665 students replied to the self-administered questionnaire survey(2,207 in academic high school, 3,458 in business high school). The major findings were as follows; The proportion of drinking, smoking experience was 55.0%, 45.8%, respectively, and the proportion of current drinker, current smoker was 27.2%, 27.5%. The drinking, smoking experience rate of second grade students was higher than first grade and it was higher in business high school boys. The proportion of a stimulant, a hallucinogen, hemp leaf cigarets experience was 3.2%, 1.6%, 0.1%, respectively. Drug abuse had significant association with home environment(lower economic status, frequent move, death of father or mother, apart from family), parents environment(parents' indifference, parents' drinking and smoking, etc.), school life(lower school grades, intimate friend's drug abuse, etc.), generous attitude to drug abuse, higher level of stress. Students who replied that the law prohibited immature person(students) from drinking and smoking showed lower drug abuse rate. In multiple logistic regression analysis, second grade students, business high school students, parents' indifference, lower school grades, intimate friend's drug abuse, no recognition of the fact that the law prohibits high school students from drinking and smoking, generous attitude to drug abuse, higher level of stress were significantly related with alcohol abuse and smoking. Other drugs abuse were related with above factors. On consideration of above findings, to prevent students from drug abuse, we have to try together in house, school, and society.

Pneumonia is the one of the 10 leading causes of overall mortality and the most common cause of infection-related death in Korea, especially in elderly patients. Streptococcus pneumoniae is the most common pathogen causing community-acquired pneumonia (CAP) in elderly patients, and gram-negative bacilli have also been reported as an important pathogen in Korea. Treatment guidelines for community-acquired pneumonia, which were published by the Joint Committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory Diseases, are briefly presented in this article. A special consideration should be given to active preventive measures for CAP in elderly patients, especially vaccination using a seasonal influenza and pneumococcal 23-valent polysaccharide vaccine.
