This experiment was performed to determine the stability of antiblotics in cured bone cement and the antibacterial effect with various the amount of antibiotics mixed in bone cement. Experimental animals were divided into control and antibioticimpregnated groups; 3 each for control, cloxacillin, celospor, kanamycln and panimycln groups. Antibiotic activities were measured by disk diffusion method using Staphylococcus aureus and Escherichla coli as standard organisms. The results were as follows: 1. Bone cement itself does not have antibacterial effect on the growth of Staphylococcus aureus and Escherlchia coli. Antlbiotlc impregnated acrylic bone cement showed antibacterial effects which was stable for 4 weeks. 2. In vitro test, the amount to antibiotics released In 24 hours perlod was proportional to the amount of antibiotlcs mixed in bone cement. 3. The duration of antibacterial effect was also roughly proportional to the amount of antiblotics mixed In bone cement. 4. No antibacterial effect could be measured in control groups. 4. In vivo test, the result was revealed similar patterns compared with the result of “In vitro test”, but the amounts of antibiotics released and durations of antibaterial effect was decreased. No antibacterial effect could be measured in control groups. As a result of this sutdy of this study, It is proved that the amount of antiblotics and the duratlon of antibacterial effect are proportional to the amount of antibiotics mixed in bone cemcnt. The impregnation of antiblotics in acrylic bone cement may be used to prevent and treat Infection in the orthopedic fleld.

A tibial segment in 3cm length with vascular pedicle and periosteum (Living bone graft) and the segment without vascular pedicle and periosteum (Dead bone graft) was obtained from twenty four rabbits, being divided into two group respectively. Then it was replaced with the segmental bone in the initial osteomized defect. The grade of healing and the time factor required to accomplish the repair of resected segmental tibial transplant was determined at one week interval during one to eight weeks, aimed by the,comparative studies of microscopic (gross), radiological as well as histological observation during the healing process. The average time of callus formation in the living bone graft was approximately two weeks, as compared to four weeks of the dead bone graft. Radiographically the average time of bone union in the living bone graft was four weeks, compared with seven weeks for the dead bone graft. The living bone graft was permitted to the healing process of the simple fracture at the graft-recipient bone juncture, in the contrast with the dead bone graft it was united with replacement of the grafted bone by new bone, so called “creeping substitution”.

A case of hypertrophic interstitial neuropathy in a 32 years old man developed in the median nerve is reported. This is a rare disease characterized by thickened peripheral nerves which may be palpable and visible. This case was treated by excision of transverse carpal ligament and external and internal neurolysis.

An arteriovenous fistula may be defined as a vascular abnormality in which there are one or more direct or indirect communication between an artery and a vein without any intervening capillary bed. Largely, such fistulas are divided into two groups-acquired (traumatic) or congenital in origin. There is a general agreement that congenital A-V fistula results from a failure in differentiation of the common embryonic anlage into true artery and vein. The authors have experienced a case of congenital A-V fistula formed in the 4th finger of the left hand. Such fistula is very difficult to excise completely with the conventional method. But we have obtained the excellent result by utilizing advanced meticulous microsurgical technique in excision.

OBJECTIVES: This research attempts to investigate the relationship between health risk factors and workers'behavioral changes based on individual worker's characteristics to allow the development of more effective health promotion programs in businesses places. METHODS: A questionnaire survey was conducted with 282 workers employed in small to medium sized enterprises in the Kyong-in area of Korea. The questionnaire was composed of general characteristics, a health risk assessment and an evaluation of the stage of behavior change for health promotion strategy in the workplace. RESULTS: The health risk assessment revealed that 65.7 % of male workers smoke, 70.5% of male workers do not exercise on a regular basis, 86.1 % of female workers do not exercise at all, and 78.6 % of male workers and 50 % of female workers drink alcohol. In addition, the survey identified that 29.5% of male workers are addicted to excessive drinking, as are 11.1% of female workers. Based on the four stages of behavioral changes that lead to health, the pre-contemplation stage, contemplation stage, action stage, and maintenance stage, 40.5 %, 23.7 %, 12.1 % and 23.7 % of workers are in these stages, respectively, with regards to quitting smoking. As for regular exercises, 18.4 %, 37.6 %, 17.7 %, and 26.3 % of workers belong to each stage, respectively. As for moderation in drinking, 20.9 %, 15.4 %, 10.0 %, and 53.7 % are in each stage, respectively. The rate of health managers in the active stage of quitting smoking is significantly higher than that of general workers. Among the workers who do not exercise on a regular basis, workers over 50 years-old and blue color workers are more common in the precontemplation stage than any other worker groups. CONCLUSIONS: The results of this study suggest that the stages of behavioral change vary with worker characteristics. An awareness of the effects of the high risk factors is essential for promoting workers'attendance in health promotion programs.

BACKGROUND: The incidence of hip fractures has been reported to vary geographically, and its trend has also varied widely. However, the trend in the age-adjusted incidence of hip fractures has not been well studied in Korea. After we identified eligible studies presenting multiple age-adjusted incidences of hip fractures in the Korean population in PubMed, we evaluated changes in the absolute number of occurrence and calculated the annual percentage change (APC) of age-adjusted incidences of hip fractures. METHODS: We have searched PubMed for the original and English-language literature on the incidence of hip fractures in the Korean population published since 2000. The studies presenting multiple age-adjusted incidences of hip fractures were selected. We evaluated the change in the absolute number of hip fractures and calculated the APC of age-adjusted incidences of hip fractures for each study. RESULTS: Three eligible articles were identified. The absolute number of hip fractures for both genders increased over time in all three studies although the operational definition of hip fracture differed from one another. The APC of the age-adjusted incidence of hip fractures was positive for women and negative for men. However, the change was not statistically significant in both genders during each study period (2001–2004, 2005–2008, and 2006–2010, respectively). CONCLUSIONS: The age-adjusted incidence of hip fractures was stable among men and women, while the absolute number of hip fractures increased for both genders in Korea. Further studies with longer study periods on age-adjusted incidences are required to better determine the trend in the incidence of hip fractures in Korea.

Measurement of spinal range of motion(ROM) can be effectively used in guiding the direction of therapy, determining the patient's response to rehabilitation treatment and functional assessment. However for a method of measurement to be commonly used in clinical and research settings, it must be easy to perform, rapid and highly reliable. The purpose of this study was to determine the possibility of clinical application of 2-dimensional motion analysis system to measure spinal ROM in patients with low back pain(LBP). Subjects included 10 healthy males and 10 patients with LBP. Using Electronic Digital Inclinometer (EDI 320) and 2-dimensional motion analysis system, thoracic, lumbar and pelvic ROMs were measured for trunkal flexion, extension, lateral flexion and rotation. Also proportions of decreased ROMs in LBP patients relative to healthy subjects and movement patterns of each spinal segment according to time sequence were investigated. LBP patients compared to normal subjects showed significantly low spinal ROM(P<0.05) except thoracic and pelvic ROM for extension. When looking at the change of each spinal ROM in respect to time with motion analysis system, normal subjects showed synchronized and sigmoid motion curve time from the initiation to the end of motion in all areas of spine during 4 motions. LBP patients took longer time from the initiation to the end of each motion, and showed smaller initial change and fluctuation in spinal ROM during each motion compared to normal subjects. The results of this preliminary study suggest that 2-dimensional motion analysis system can be effectively used for measuring spinal ROM in patients with LBP.

Angioleiomyoma is a solid benign tumor, which is often painful. It can be found in the dermis, subcutaneous fat and fascia. Peak incidence is during the fourth to sixth decades of life. Angioleiomyoma in the hand can be treated with simple excision, and is relatively rare in the hand. So far, there has been no report of angioleiomyoma in the hand in South Korea. The authors experienced two cases of angioleiomyoma in the hand; one in the second web space and the other in the fifth metacarpal region. Both patients were treated by simple excision. There was no evidence of recurrence at one-year follow up.
