Purpose: To investigate the results of treatment of reverse oblique trochanteric fractures with compression hip screw. Methods: We reviewed the results of 12 cases of reverse oblique trochanteric fracture treated with compression hip screw from January 2000 to December 2006 which could be followed up for more than 1 year. The mean follow up period was 26 months (15~40). The mean age was 48 years old. Injury mechanism was composed of 6 cases of traffic accident and 6 cases of fall down. 8 persons were man. We investigated the union time, degree of neck-shaft angle change, amount of sliding of compression hip screw, complications, functional and clinical results. Results: 10 cases were united and the mean union time were 5 months (3~8). The mean neck-shaft angle change was 3.5 degrees (0~12). The amount of sliding of compression hip screw was 8.9 mm (2~24). There were six coxa vara, six leg due to coxa vara shortening, two nonunion, and one superficial infection. Unsatisfactory results of Jensen's social function score and Parker and Palmer's mobility score were studied. Conclusion: The results of treatment of reverse oblique trochanteric fractures with compression hip screw were relatively unsatisfied.

Background: Examination of the effects of deer antler, old antler, and antler glue on postmenopausal osteoporosis in an ovariectomized Sprague-Dawley rat model. Methods: The study involved 7 experimental groups; SHAM (sham-operated rats), OVX (ovariectomized rats), E2 (ovariectomized rats with estradiol $10{\mu}g/kg$ daily, orally), DA (ovariectomized rats with deer antler extract 5.83 mg/kg), OA (ovariectomized rats with old antler extract 3.8 mg/kg), low-AG (ovariectomized rats with low dose of antler glue powder 12.5 mg/kg), high-AG (ovariectomized rats with high dose of antler glue powder 37.5 mg/kg). After 6 weeks of treatment, body weight, blood calcium, phosphorus, estradiol, liver [alkaline phosphatase (ALP), aspartate transaminase (AST), alanine transaminase (ALT)] and kidney [blood urea nitrogen (BUN)/creatinine ratio] function, and femoral bone mineral density (BMD) were measured. Results: The body weights of DA, OA, low-AG, and high-AG groups did not significantly differ from OVX group. Blood estradiol levels were significantly increased in the DA, low-AG, and high-AG groups compared to the OVX group. Blood calcium, phosphorus, ALP, AST, and ALT levels and BUN/creatinine ratio did not show significant changes in the DA, OA, low-AG, and high-AG groups. BMDs of the femur, and femoral head and neck were significantly increased in the low-AG group. In the OA group, the BMD of the femoral head and neck was significantly increased. Conclusion: Treatment with deer antler, or antler glue for 6 weeks was effective for increasing estradiol and femoral BMD in ovariectomized rats, suggesting that this may be of therapeutic benefit for osteoporosis.

This study was to investigate the relation of nutrients intake, health status, and bone mineral density in middle-aged women. Daily nutrients intake were analyzed by convenient method. The BMD of subjects were measured by Dual Energy X-ray Absorptiometry(DEXA). BMD was measured at the spine(vertebrae L2-L4) and femur(neck, Ward's triangle and trochanter). The nutrients intake of subjects were higher than recommended dietary allowances(RDA) except for calorie, iron, calcium, vitamin B1. Nutrients intake of vitamin A(p<0.05), iron(p<0.01), vitamin $B_2$(p<0.05), niacin(p<0.05), and vitamin C(p<0.05) between $\leq$49 yr group and $\geq$50 yr group. Mean daily intake of calcium was much less than the Korean RDA, 78.5% in $\leq$49 yr group and 77.3% in $\geq$50 yr group. 35.8% of the subjects under 50 years of age($\leq$49 yr group) and 77.4% of the subjects from 50 years up($\geq$50 yr group) were classified as osteopenia or osteoporosis. BMD of L2-L4 were positively correlated with height(p<0.05), weight(p<0.05) and BMI(p<0.05). BMD of femoral neck was positively correlated with BMI(p<0.05), BMD of Ward's triangle was positively correlated with weight(p<0.001). But BMD of L2-L4 and femoral neck were negatively correlated with age(p<0.05), menarche(p<0.05). BMD of Ward's triangle was negatively correlated with age(p<0.001). The BMD of L2-L4 were positively correlated with animal protein(p<0.05), calcium(p<0.05) and iron(p<0.05). The BMD of femoral neck was positively correlated with animal protein(p<0.05). The BMD of Ward's triangle was positively correlated with animal protein(p<0.001) and iron(p<0.001). The above results suggest that it should be difficult to prevent middle-aged women's bone destruction through nutrients intake. Further investigation is necessary to prove the mutual relations between BMD, exercise, and calcium intake. Therefore, middle-aged women will need proper exercise as well as Ca supplementation in order to prevent osteoporosis with aging.

The purpose of present study was to assess the change of bone mineral density(BMD) and the influences of anthroopometric indices and body composition on BMD in Korean women in Taegu. Subjects were 242 healthy female in the range of 7-67 years old, were divided into 4 age groups in order to assess the influence o factors on BMD according to age. Body composition and BMD measurements of lumbar spine, femur(neck, ward's triangle, trochanter) and total body were performed by dual energy X-ray absorptiometry. The analysis indicated that BMD of most region was positively related to body weight, BMI in all groups 4(50-67years), and closely related to femurs than lumbar spine. This study found correlations between BMD and both total fat body mass and total lean body mass in group 1, 2, 3, and correlations between BMD and only total fat body mass and in group 4. But on regression models the most significant prediction of BMD throughout the skeleton was total lean body mass in group 1(7-16years)and 2(17-34years, and total fat body mass in group 3 and 4. It is concluded that the our data can be used to screen early women of low bone mass. This study confirms that one of the most effective way to prevent osteoporosis and the fractures is to maximize peak bone mass in early life and to minimize bone loss through maintaining adequate weight.

The effect of the hydroxyapatite coatings on Titanium implants has been the subject of recent investigations. So far, the use of HA coating remains substantially controversial.This study was aimed to evaluate histologically the bone healing patterns around titanium plasm sprayed(TPS) amd HA-coated implant after implantation into the femur neck of ten adult dogs. After implantation, animals were sacrificed at the intervals of 2,4,6,8 and 12 weeks.The fluorescent dyes were injected on the postoperative 4th and 12th week into the animals supposed to be killed at the 12th week. The morphology and direction of new bone formation was similar in both TPS and HA-coated implants.There was a tendency toward more bone formation in the cortical bone area than in the cancellous bone area. Histologically,in the interface of the HA-coated implants, bone response and bone maturation was faster, compared to the TPS implants in the 2nd and 4th week. By fluorescent microscopy, new bone formation was active in the 4th week around both implants and was directed from the periosteum overlying cortical bone to the cancellous bone. These results suggest that the bone formation and maturation is faster during the early healing stage in the interface of the HA-coated implant and where the cortical bone quality is poor, HA coated implant is superior to the TPS implant in the early phase of new bone formation.

The preventive effect of Salvia miltiorrhiza extracts (SMEs) on the progress of bone loss induced by ovariectomy (OVX) was studied in rats. We measured body weight and bone histomorphometry in sham, OVX or SMEs-administered OVX rats. From light microscopic analyses, a porous or erosive appearances were observed on the surface of trabecular bone of tibia in OVX rats, whereas those of the same bone in sham rats and in SMEs-administered rats were composed of fine particles. The trabecular bone area and trabecular thickness in OVX rats decreased by 50% from those in sham rats, these decreases were completely inhibited by administration of SMEs for 7 weeks. In this study, the mechanical strength in femur neck was significantly enhanced by the treatment of SMEs for 7 weeks. In OVX rats, free T3 was normal in all cases, whereas free T4 was significantly increased. Although there was no difference between OVX and SMEs-administered rats in T3 level, we have found significant difference between them in T4 level. These results strongly suggest that SMEs are effective in preventing the development of bone loss induced by OVX in rats.

Purposes: To identify the predictors of calcium intake behavior and examine the relationships among bone mineral density, osteoporosis knowledge, osteoporosis health belief, osteoporosis self efficacy and calcium intake behavior of postmenopausal osteoporosis patients. Methods: The subjects consisted of 94 patients. The measurement tools were osteoporosis knowledge test, osteoporosis health belief scale, osteoporosis self-efficacy and calcium intake frequency questionnaire. The data were analyzed using the SPSS WIN 11.0 program. Results: The bone mineral density of the lumbar were $0.75g/cm^2$, T-score -2.67 and the femur neck were $0.67g/cm^2$, T-score -2.30. There was statistically a significant correlation between calcium intake behavior and health motivation (r=0.449, p=0.000) among the osteoporosis health belief. In hierarchial multiple regression analysis, current spouse(12.8%) and health motivation(19.9%) of the osteoporosis health belief explained the 32.7% of variance in calcium intake behavior. Conclusion: Nursing intervention should be developed for increasing the calcium intake behavior through promoting health motivation for the postmenopausal osteoporosis women having no spouse currently.

To examine the bone-protective effects of Puerariae Radix (PR) in an estrogen-deficient animal model, we treated ovariectomized rats with PR at a dose of 10.0 mg/kg 3 times a week for 16 weeks. Our results showed that PR increased mineral content and density of the trabecular bone at the neck of the left femur. Moreover, biochemical data indicated that PR had a positive effect on bone turnover. No endometrial hyperplasia was detected in the PR group. The present data suggest that PR should be considered for use in the treatment of bone loss in women with postmenopausal osteoporosis.

Salvia miltiorrhiza Radix root extracts (SMR) was evaluated for inhibition of the progress of bone loss induced by ovariectomy (OVX) in rats. We measured body weight and bone histomorphometry in sham, OVX and SMR-administered OVX rats. From light microscopic analyses, porous or erosive appearances were observed on the surface of trabecular bone of tibia in OVX rats, whereas those of the same bone in sham rats and in SMR-administered rats were composed of fine particles. The trabecular bone area and trabecular thickness in OVX rats were decreased by $50\%$ from those in sham rats, and these decreases were completely inhibited by administration of SMR for 7 weeks. In this study, the mechanical strength in femur neck was significantly enhanced by the treatment of SMR for 7 weeks. In OVX rats, free $T_3$ was normal in all cases, whereas free $T_4$ was significantly increased. Although there was no difference between OVX and SMR-administered rat in $T_3$ levels, we have found significant difference between them in $T_4$ level. These results strongly suggest that SMR may be beneficial for preventing bone loss in OVX rats.

PURPOSE: The aims of this study were to assess the intra-tester and inter-tester reliability and validity of hip range of motion using a smart phone in hip operative patients. METHODS: Twenty-five patients (eight total hip arthroplasty and seventeen femur neck fracture) participated in this study. The range of motions in active and passive hip flexion, abduction and external rotation were measured with a goniometer and smart phone over two times by two observers. The intra-tester and inter-tester reliability were evaluated using the intraclass correlation coefficient (ICC2,1). The validity was measured by Pearson's correlation coefficient RESULTS: The intra-observer reliability was good in all measured items (ICC>0.78). The inter-observer reliability was high with ICC (>0.90). All correlation coefficients of smart phone and goniometer was greater than 0.85 and showed a significant positive correlation (p<0.01). CONCLUSION: The range of motion measurement with a smart phone showed acceptable reliability. Therefore, it could be convenient and have economical benefits to measure the range of motion of the hip joint using a smart phone.
