Objjectives : The purpose on this report is to show the clinical efficacy of korean medical treatments for femoral neck fracture treated non-operatively. Methods : The patient with femoral neck fracture was treated using acupuncture, herbal medication, And the efficacy of treatment had been measured in visual analog scale(VAS) scores and Harris hip scores(HHS) per one month for seven months. Results : After treatment, HHS score had been increased from 0 to 74 and VAS of femoral pain had been decreased form 10 to 1.5. Conclusions : From the above results, It is demonstrated that korean medical treatments is effective on patient with femoral neck fracture treated non-operatively.

Due to the increasing needs of anti-fall device for elderly, it is required to develop the test rigs for fall simulation. The femoral bone model consists of silicone and steel is used as an effective device to simulate falls. In this work, we propose five different femoral bone models and analyse them by using a commercial FEA tool. It has been shown that two kinds of simplified models exhibit the simulated side falls with an error range of ~1% in the impact load of femoral neck compared with full model. Especially, the upper tissue model is found to provide us with the best efficient test environment, attributable to its simple structure.

This study was designed to examine the morphological measurement and characteristics of trabecullae based on femoral radiographic image for prediction of osteoporosis. Study subjects were 34 females (average age of 62.1 years) and 6 males (average age of 60.1 years), they were categorized into normal group and osteoporosis group in accordance with the T-score value. Measurement of the bone density of femoral bone was measured with DEXA(Dual Energy X-ray absorptiometry). ROI(Region of interests) was selected on femoral neck and trochanter. Characteristics of trabecullae was analyzed by using the skeletonization analysis of trabecular image. Morphological measurement was analyzed through femoral radiographic image in order to examine the correlation with osteoporosis. The result demonstrated statistically significant correlation between neck cortical thickness, shaft width, shaft cortical thickness, periphery, mean gray level and trabeculae area with BMD average (T-score) of femoral part. The results show that morphological measurement and characteristics of trabecullae based on femoral radiographic images for osteoporosis prediction could be effective.

성인 남성들이 2002년부터 2006년 까지 건강검진을 받기위해 대학병원을 내원한 성인 남성 80명을 개인별 골밀도를 5년간 관찰하여 분석하였다. 연구 대상자 성인 남성 80명의 평균연령은 $43.15{\pm}4.82$세였다. 대퇴경부의 골밀도는 1차 측정에서 -0.61에 비하여 4차 및 5차 측정에서 유의하게 감소하였으며, 척추 골밀도는 1차 측정 -0.67에서 2차 측정에서 유의한 감소를 나타냈지만 3~5차 측정에서 유의한 차이를 보이지 않았다. 생활습관에 따른 음주, 흡연, 운동, 식습관에 따른 군 간의 대퇴경부 및 척추 골밀도 변화 값의 차이는 보이지 않았다. 1차 측정에서의 대퇴경부 골밀도를 기준으로 골밀도 상($0{\leqq}BMD$), 중($-1.0{\leqq}BMD<0$), 하(BMD < -1.0) 집단에서 1차 측정과 5차 측정 골밀도의 차이를 비교하였을 때, 상 집단에서 대퇴경부 골밀도가 1차 $0.67{\pm}0.76$에서 $0.42{\pm}0.93$로 유의하게 감소하였다. 다른 집단에서는 전후 비교에서 유의한 차이를 보이지 않았다. 대상자들의 나이에 관계없이 젊어서부터 골밀도가 낮은 사람들은 대퇴경부 및 척추의 골밀도가 낮아 있었으며, 골밀도가 높은 사람들은 1차 측정 때부터 5차 측정 때까지 높았다. 대퇴경의 골밀도는 1차 측정에 비해 5차에서 유의한 감소를 나타내어 척추보다는 대퇴경부의 골밀도에 주의하도록 한다.

This study was conducted to investigate the factors which are related to Bone Mineral Density(BMD) of female for prevention of osteoporosis. We measured the BMD of lumbar spine(L2-L4) and femoral neck in 4802 female, using dual energy X-ray absorptionmetry(DEXA; DPX-alpha. Lunar, U.S.A.). and then analysed the 9 factors-age group, body mass index(BMI), amount of smoking, drinking, exercise, sleep, and fast blood sugar-which are related to BMD of female. The following results were obtained : 1. In age group, T-score was the highest at 36－42(六七) years group in lumbar spine(L2-L4) and at 15－21(三七) years group in femoral neck. and then it was decreased rapidly after 43－49(七七) years group in both lumbar spine(L2-L4) and femoral neck. Therefore we concluded that T-score of female in lumbar spine(L2-L4) and femoral neck change according to age group in $\ll$Hwangjaenaekyong Somun; 黃帝內經 素問$\gg$. 2. In BMI, T-score of lumbar spine(L2-L4) and femoral neck were increased according to BMI increase. 3. In amount of drinking and smoking, T-score was highest in heavy groups(women who have drunk soju more than 4 bottles for a week) in both lumbar spine(L2-L4) and femoral neck. But there t was no significant difference in comparison according to age group. 4. In exercise, T-score was higher in exercising group than non exercising group. And it appeared that women who have taken proper exercise had higher T-score than women who have taken exercise daily. 5. T-score was higher in women who ordinarily sleep well in both lumbar spine(L2-L4) and femoral neck than sleep badly. And there was significant difference in 43-56 years group. 6. T-score was low in the group that exceed 110mg/dl in fast blood sugar. Conclusions : The age group in $\ll$Hwangjaenaekyong Somun; 黃帝內經 素問$\gg$ is related to BMD of women. And risk factors-BMI, exercise, sleep, fast blood sugar, thyroid disease-are related to BMD of women. Therefore we expect that this study will help for prevention of osteoporosis of women, and further study will be achieved.

인체의 해부학적 구조에 관해 다른 영상들보다 정확한 정보를 제공하는 MRI에 대해 많은 연구가 진행중이다. 본 논문에서는 대퇴골두 무혈성 괴사의 자동 진단에 필요한 대퇴골두 영역의 추출에 관한 효과적인 방법을 제안한다. 대퇴골두의 해부학적 특성과 Hough transform을 이용하여 대퇴골두 영역을 설정하였고, 대퇴골두 영역을 분할하는 방법으로서 영역 확장법과 히스토그램 기반 영역 분할 방법의 장점을 결합한 방법을 고안하였다. 본 논문에서 제시한 방법은 정상적인 대퇴골두와 무혈성 괴사의 초기 단계의 대퇴골두 뿐만 아니라 괴사가 심한 대퇴골두에 대해서도 좋은 결과를 얻을 수 있었다.

대퇴 전염각의 정확한 측정은 뼈를 절개하여 각을 조절하는 시술(derotation osteotomy)에 있어서 매우 중요하다 대퇴 전염각을 정확히 측정하기 위해서는 대퇴골 장축과 목축, 관절구축의 정확한 선정이 필수적이다. 기존의 2차원 영상에 의한 대퇴 전염각의 측정 방법은 간단하지만 3차원 공간상에서 축들을 결정하기 모호한 단점을 가지고 있고, 3차원 영상을 이용하는 방법은 뼈를 밖에서 직접 측정하는 것과 같은 결과를 얻을 수 있어 2차원 방법보다는 정확한 측정이 가능하나 처리과정이 복잡하고 정량적이고 객관화된 결과를 얻는 것이 어려운 문제점을 가지고 있다. 본 연구에서는 대퇴골을 3차원으로 모델링하여 정량적이고 객관적인 대퇴 전염각의 측정법을 제시한다. 이것은 먼저 촬영된 슬라이스 영상들을 3차원상에서 재구성한 뒤, 대퇴골두와 목 모델로부터 대퇴골 목축을 정하고, 대퇴 관절구 모델로부터 대퇴 관절구축을 결정한다. 또한, 대퇴골 주축을 원통으로 모델링하여 장축을 결정한다. 대퇴 전염각은 대퇴관절구의 접평면에 대한 대퇴골축의 기울어진 정도로 정의되며, 이 정의를 이용하여 대퇴 전염각을 구한다. 결과에서 20명 CT영상으로부터 대퇴골 샘플을 측정하여 기존의 2차원 및 3차원 영상법의 결과와 비교하여 제시한 방법이 객관적이고 정확한 측정방법임을 검증한다.

This report showed the clinical outcome of an elderly patient with a femoral neck fracture who was treated non-operatively with Korean medical treatment. The patient had acupuncture, herbal medication, moxibustion, and participated in physical rehabilitation for 3 months. The effects of Korean medical treatment were measured every 2 weeks using the numeric rating scale (NRS) and the Harris hip score (HHS). After treatments, the NRS score for hip pain decreased from 8 to 2, and the HHS increased from 0 to 43. A 42-month follow-up showed the patient's NRS score was 0 and the HHS was 61. Furthermore, an X-ray showed complete union of the femoral neck fracture with no suspicion of avascular necrosis. These results suggest that Korean medical treatment can effectively reduce pain and aid rehabilitation in patient with femoral neck fractures with no surgery, resulting in complete union of the fracture.

There were some controversies about direct cause of hip fracture. We attempted to look at 40 osteoporotic proximal femur fractures in women over 50 years between March in 1999 and Febuary in 2000. The bone density of the fracture group and the healthy 85 control group was measured by Dual Energy X-ray absorptiometry(DEXA). The result was compared using age matched paired T test. The results were as follows ; 1. The femoral neck fractures were 14 cases and the trochanteric fractures were 26 cases. Mean age at a fracture was 67.1 years in neck fracture group and 76.5 years in trochanteric fracture. 2. In the control group, the bone density of both side of the proximal femur was measured and it showed statistically no difference between both sides in same person. 3. The bone density of neck, Ward's triangle, trochanter(P<0.05) and lumbar spine(P<0.001) was significantly reduced in the proximal femoral fracture group comparing with the control group. 4. The bone density of neck, Ward's triangle, trochanter(P<0.05) was significantly reduced in the proximal femoral neck fracture group comparing with the control group, but there was no statistical difference in lumbar spine comparing with the control group. 5. The bone density of neck, Ward's triangle, trochanter and lumbar spine(P<0.001) was significantly reduced in the proximal femoral neck fracture group comparing with the control group. We concluded that the bone mineral densities(BMD) of proximal femur and lumbar spine had decreased in hip fractures but that the bone mineral density and T-score % of the proximal femur were statistically lower than that of the lumbar spine. We suggest that measuring the bone mineral density of the proximal femur may reflect the weakness of the proximal femur more precisely than measuring the bone mineral density of the lumbar spine.
