STUDY DESIGN: Thirty-fiye thoracolumbar and lumbar burst fractures treated with pedicle screw instrumentation were assessed on loss reduction. OBJECTIVE: To compare the mechanical results of simple posterior fixation and posterior fixation with anterior augmentation by anterior interbody fusion, disc space fusion or longer construct. SUMMARY OF BACKGROUND DATA: Althrough the pedicle screw instrumentation provides good mechanical stability, two segment fixation without anterior column augmentation may not be adequate to withstand the repeated axial load. METHODS: Fifteen patients were treated with two segment fixation alone(Group 1), seven with anterior interbody fusion(Group 2), another seven with disc space fusion(Group 3) and remaining six with longer construct involving two segments abode the fracture(Croup 4). Change of anterior body height, upper disc height, lower disc height, kyphotic angle, inter-screw angle and gross screw bend- ing were measured using post-operative and follow-up lateral radiographs. RESULTS: Comparing the two groups(Croup 1 Ys. Group 2, 3, 4), the Group 1 showed definitely more loss of reduction than those groups which had anterior augmentation. But, loss of anterior body height was not significantly different. Comparing the four groups, loss at upper and lower disc height was significantly greater in the Group 1 than the Group 2. Change of kyphotic angle was significantly higher in the Group 1 than the Group 4 and change of inter-screw angle was also higher in the group 1 than every other group. Seyen patients in the Group 1 showed gross screw bending, but none in the Group 2, 3 and 4. All the seven patients with screw bending showed loss of inter-screw angle more than 5 . CONCLUSIONS: These results mean that anterior column augmentation is necessary for the treatment of thoraco-lumbar burst fracture. All the three methods(Group 2,3,4) are effective to prevent excessive loss of correction and screw bending. The best method should be selected considering the characters of each fracture.

The use of a pneumatic tourniquet is potentially associated with injury to underlying muscles, vessels, and nerves if excessive pressure occurs beneath the toumiquet. In order to minimize the risk of soft tissue injury, the lowest tourniquet pressure that maintains a bloodless operative field should be used. A clinical study was undertaken to evaluate the pneumatic tourniquet setting required for adequate hemostasis in upper extremity surgery. From March to September in 1984, the subcutaneous soft tissue pressure of the 20 upper extremities beneath a pneumatic toumiquet in the arm were measured directly and the following results were obtained. 1. The underlying subcutaneous soft tissue pressure was not affected by adult, age, arm circumference, and blood pressure of normal range. 2. The underlying subcutaneous soft tissue pressure showed direct correlation with the tourniquet pressure respectively. 3. A tourniquet preasure of more than 250 mmHg was not rarely required in a normotensive individual.

Ligamentous injury of the knee which could be easily occur in sports or traffic accidents resulted in more and severe disability than that of other joints. Rupture of the anterior cruciate ligament which restrain hyperextension, excessive rotation and anterior motion of tibia on femur is the most frequent and significant injury of the knee. Its treatment and clinical significance is one of the most controversial issue and its incidence tends to increase. From 1983 to 1985, modified Scott operation were performed on 10 patients at the department of orthopedic surgery, Chung Ang university hospital. Following results are obtained. 1. No limitation of range of motion of the knee was developed. 2. Intra-articular fixation by use of pull-out wire was done and special consideration was done for the site of fixation on tibia plateau and method of dilatation of posterior capsule. 3. Of the ten patients, nine had negative anterior drawer test, postoperatively.

BACKGROUND: The relation between treadmill exercise testing and ambulatory ST segment monitoring in detection of ischemia in patients with coronary artery disease has not been well established, with pathophysiologic mechanisms underlying the development of ischemia in the ambulatory setting not being well elucidated. This study was performed to determine the relation between myocardial ischemic indexes on exercise testing and on Holter monitoring. METHODS: We analized 25 patients with stable angina and angiographically documented coronary artery disease, who exhibited ischemia both on a Bruce protocol exercise test and on 24-hr Holter monitoring while receiving routine antianginal medications. RESULTS: Mean heart rate at the onset of 1mm ST segment depression during exercise testing(74.4 VS 114.1 beats/min, p<0.01). Overall the correlations between ischemic indexes on both test were weak. But heart rate at the onset of ischemic episodes during Holter monitoring had a good correlation with heart rate at 1mm ST depression during exercise test. And the number of ischemic episodes on Holter monitoring revealed a weak negative correlation with duration of exercise during treadmill test. CONCLUSION: Ischemic indexes on exercise testing cannot accurately predict ischemic indexes on Holter monitoring in patients with coronary artery disease. In that regard, Holter monitoring may provide other clinical information in addition to that obtained by exercise testing in selected patients.
