Thirty years ago a major arterial laceration was devasting injury, threatening survival of the limb in almost every case. Increased awareness of vascular injuries and of feasibility of immediate and more advanced arterial repair techmique reduced the amputation rate. The authors reviewed 163 patients of vascular injuries in extremities, who were admitted to Severence Hospital of the Yonsei University College of Medicine from January, 1979 to December, 1986. The results were follows : 1. Among the 163 patients, 146 patients were male patients. 2. Most of the victims were in their twenties. 3. The most common cause in the upper extremity was glass injury. The most common cause in the lower extremity was being struck by moving vehicles. 4. More complications in vascular injuries were associated with severe soft tissue crushing and comminuted fracture of the bone. 5. More favorable results can be gained through the use of microvascular techniques than through conventional techniques in vascular reconstruction.

OBJECTIVE: It has been known that the posterior pedicle screw fixation provides good mechanical stability in unstable burst fracture. But, posterior fixation without anterior column support may not be adequate to withstand the axial load and to keep the corrected kyphotic angle. We present results of one stage fixation by posterior approach in unstable burst fracture. METHODS: Nine patients with unstable burst fracture were treated with posterior fixation and intervertebral fusion using titanium mesh cages and pedicle screws. The canal decompression was achieved by laminectomy and partial pediculectomy through the posterior approach. In all cases, the short segment fixation and anterior column support with cage were performed on the one stage operation. RESULTS: Of nine patients, seven was satisfied with excellent clinical results except two cases of the Frankel's grade A. All patients had good stabilization of spinal column and enough decompression without any neurological complications. It was possible to maintain the corrected kyphotic angle with the circumferential stabilization(three column fixation). CONCLUSION: The anterior and posterior column fixation through the posterior approach provides good stability and decompression in the patients with unstable burst fracture.

The purpose of this study was to compare the occupational health concerns and opinions among 4 groups: workers, employers and managers, government officials, and health & safety managers. It could help establishing occupational health plans efficiently and providing the way to solve health problems in workplaces in the Inchon area. The delphi technique which is used for deciding group opinion was adopted for this study. Questionnaires regarding health problems and their priorities in the workplaces were sent to four groups three times. All items were measured by five degree ordinal scales. The four groups agreed with questionnaire items, improvement of working environment, occupational health concerns of the employers, the health concerns of workers, and measurement and analysis of working environment, as the upper five priorities for solving the occupational health problems. Besides with the first five priorities, health examinations, health education, and occupational diseases were suggested as important health problems in workplace.

To investigate perception and attitude toward Group Health Management and Services System for Small and Medium Industries, a survey using self-administered questionnaire was conducted to a part of industries in Inchon, at October 1992. Major dependent variables were perception, attitude, and practice related with Group Health Management and Service System; these variables were measured by 3-point Likert like scale consisted of 7, 5, and 5 items, respectively. Data were collected in 149 industries, 72.7% out of 205. Perception was slightly high, 1.25; attitude was some positive, 1.46; and practice was some passive, 0.94. Major determinants of perception, attitude, and practice were sex and age of industry's health manager; perception influenced upon attitude, and perception and attitude had positive effect upon practice. To activate Group Health Management and Service System, it is necessary to develop education and promotion programs for industry's health managers of small and medium industries.

BACKGROUND: The use of osteoanabolic agents to facilitate fracture healing has been of heightened interest to the field of orthopaedic trauma. This study aimed to evaluate the evidence of teriparatide for fracture healing and functional recovery in osteoporotic patients. METHODS: We performed a literature search in PubMed, EMBASE, Web of Science, and the Cochrane Library using terms including “Fracture” [tiab] AND “Teriparatide [tiab] OR “PTH” [tiab]. RESULTS: This systematic review included 6 randomized clinical trials, 4 well-controlled retrospective studies, and 1 retrospective post hoc subgroup analysis. Fracture location was 2 in pelvis, 3 in proximal femur, 1 in distal femur, 1 in shoulder, 2 in wrist and 2 in spine. The use of teriparatide yielded positive effects on radiographic bone healing in 6 studies, but was not associated with better radiographic outcome in 3. In terms of functional recovery, teriparatide injection was related with decrease in pain or shorter time to mobilization in 6 studies, but not related with pain numerical scale and mobility in 3. CONCLUSIONS: Our findings suggest that teriparatide provide selective advantages to fracture healing or functional recovery in the management of osteoporotic fractures. A better understanding of the role of teriparatide on osteoporotic fractures requires greater evidences from large volume prospective trials.
