  • 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.

  • 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.

  • Objective: This study aimed to investigate the usefulness of bone single-positron emission tomography/computed tomography (SPECT/CT) of the hip in predicting the later occurrence of avascular necrosis (AVN) after slipped capital femoral epiphysis (SCFE) or femoral neck fracture in pediatric patients. The quantitative parameters of SPECT/CT useful in predicting AVN were identified. Materials and Methods: Twenty-one (male:female, 10:11) consecutive patients aged < 18 years (mean age ± standard deviation [SD], 11.0 ± 2.7 years) who underwent surgery for SCFE or femoral neck fracture and postoperative bone SPECT/CT were included. The maximum standardized uptake value (SUV), mean SUV, and minimum SUV of the femoral head were measured. The ratios of the maximum SUV, mean SUV, and minimum SUV of the affected femoral head to the contralateral side were determined. Patients were followed up for > 1 year after the surgery. The SPECT/CT parameters were compared between patients who developed AVN and those who did not. The accuracy of SPECT/CT parameters for predicting AVN was assessed. Results: Six patients developed AVN. There was a significant difference in the ratio of the mean SUV among patients who developed AVN (mean ± SD, 0.8 ± 0.3) and those who did not (1.1 ± 0.2, p = 0.018). However, there were no significant differences in the ratios of the maximum and minimum SUV between the groups (all p = 0.205). For the maximum, mean, and minimum SUVs, no significant differences were observed between the groups (p = 0.519, 0.733, and 0.470, respectively). The cutoff mean SUV ratio of 0.87 yielded a 66.7% sensitivity and 93.2% specificity for predicting AVN. Conclusion: Quantitative bone SPECT/CT is useful for evaluating femoral head viability in pediatric patients with SCFE or femoral neck fractures. Clinicians should consider the high possibility of later AVN development in patients with a decreased mean SUV ratio.

  • The purpose of this study was to investigate correlations between bone mineral density (BMD) and dietary and non-dietary factors in female college students. The BMD of the subjects (n = 38) was measured using DEXA (Dual Energy X-ray Absorptiometry) at lumbar spine and three femoral sites including femoral neck, ward's triangle, and femoral trochanter. Three-day 24-hour dietary recall data were collected from each subject to assess consumption levels of nutrients and food groups. The mean (${\pm}SD$) values of age, age of menarche, height, weight, body mass index (BMI), waist-to-hip ratio (WHR), fat mass, and % body fat of the subjects were 21.34 (${\pm}1.73$) years, 13.1 (${\pm}1.2$) years, 161.3 (${\pm}5.0$) cm, 53.7 (${\pm}7.2$) kg, 20.6 (${\pm}2.6$) $kg/m^2$, 0.80 (${\pm}0.04$), 15.4 (${\pm}4.4$) kg, and 28.2 (${\pm}4.7$), respectively. The BMD values of lumbar spine, femoral neck, ward's triangle, and femoral trochanter as T-value were $1.150{\pm}0.13\;g/cm^2$, $0.932{\pm}0.11\;g/cm^2$, $0.850{\pm}0.13\;g/cm^2$, and $0.721{\pm}0.10\;g/cm^2$, respectively. The daily mean energy intake of the subjects was 1660.6 kcal. The intake levels of carbohydrate, calcium, iron, vitamin C, and folic acid were lower than the KDRIs, while those of fat, phosphorus, sodium, vitamin A, and vitamin $B_6$ were higher than the KDRIs. Significantly negative correlation were detected between consumption of fat and oils and the BMD of all sites measured (p < 0.05). Potato and starch intake was negatively correlated to the BMD of femoral neck and word's triangle (p < 0.05). The intake of cereals was found to be negatively correlated to the BMD of ward's triangle (p v 0.05). There was also negative correlation of intake of soybeans and products with the BMD of lumbar spine (p < 0.05). Weight and muscle mass were positively correlated to the BMD of both lumbar spine and femurs (p < 0.01). Significantly positive correlations between BMI, and fat mass and the BMD of lumbar spine were observed (p < 0.001). Additionally fat mass was positively correlated to the BMD of femoral neck. WHR and % body fat were positively correlated to the BMD of lumbar spine (p < 0.05). Negative correlation was found between a serum calcium level and the BMD of femoral neck (p < 0.05). In summary non-dietary factors generally showed significant correlations with the BMD of lumbar spine, while several dietary factors showed significant correlations with the BMD of femurs.

  • Bone mineral density (BMD) is influenced by genetic and environmental factors. Among genetic study; calcitonin receptor (CTR) gene is a good candidate influencing the inter-individual difference in BMD because CTR is involved in calcium and bone metabolism. Thus, we investigated the distribution of C1377T polymorphism in the CTR gene among male Korean elite athletic and control groups, respectively and also an association with BMD in lumbar spine and femoral neck. Our results suggested that this polymorphism of CTR gene was not significantly associated with lumbar spine or femoral neck BMDs in the both groups, respectively. However, we found that there was the racial difference in genotype distribution of this polymorphism between Caucasian and Asian populations. Though we could not detect the significant association between C1377T polymorphism of CTR gene and lumbar spine or femoral neck BMDs, further studies using other ethnic groups are necessary to clarify the precise role in BMD of CTR gene.
