Background: Few studies have investigated the effects of sarcopenia on postoperative outcomes including mortality rates following surgery for osteoporotic hip fractures. The purpose of the present study was to determine the prevalence of sarcopenia and the relationship between sarcopenia and 1- and 5-year mortality rates in a consecutive series of patients with osteoporotic hip fractures. Methods: Among patients who underwent hip surgery for osteoporotic hip fractures, this study included 91 patients subjected to abdominal computed tomography within 1 year of hip surgery. We defined sarcopenia using sex-specific cut-off points for the skeletal muscle index at the level of the third lumbar vertebra. All patients were divided into 2 groups according to the presence or absence of sarcopenia and the 1- and 5-year mortality rates were compared. To confirm factors affecting mortality in addition to sarcopenia, we examined patient age, sex, American Society of Anesthesiologists grade, location of fracture, type of surgery, and bone mineral density. Results: The 1- and 5-year mortality rates were 20.9% and 67.2%, respectively. Among the 45 patients with sarcopenia, the 1- and 5-year mortality rates were 22.2% and 82.7%, respectively. Of the 46 patients without sarcopenia, the 1- and 5-year mortality rates were 19.6% and 52.7%, respectively. Results of the Kaplan-Meier analysis showed that sarcopenia did not affect the 1-year mortality rate (P=0.793), but had a significant effect on the 5-year mortality rate (P=0.028). Both perioperative sarcopenia (P=0.018) and osteoporosis (P=0.000) affected the 5-year mortality rate. Conclusions: Sarcopenia increases the risk of 5-year mortality in patients with osteoporotic hip fractures.

The femoral fracture is the most serious problem of old ages haying osteoporotic fractures. First of all, prevention to reduce the incidence of hip fracture and to identify the risk factor is essential subject. The purpose of this study is to investigate which geometric parameters of proximal femur are related to the hip fracture risk in old ages. Author analyzed the bone density and bone content of over 60 years old women who had suffered hip fracture (n=60) and non fracture groups (n=60). Author concluded that geometric measurements of proximal femoral part made on dual energy x-ray absorptiometry can predict hip fracture independently of bone mineral density.

Background: In South Korea, 22.3% of women ${\geq}50years$ of age and 37% of women ${\geq}70years$ of age visit the doctor to obtain treatment for osteoporosis. According to the analysis of the National Health Insurance Services claim data between 2008 and 2012, the number and incidence of hip and vertebral fractures increased during the same period. Denosumab, a newly marketed medicine in Korea, is the first RANK inhibitor. Methods: A cost-utility analysis was conducted from a societal perspective to prove the superiority of denosumab to alendronate. A Markov cohort model was used to investigate the cost-effectiveness of denosumab. A 6-month cycle length was used in the model, and all patients were individually followed up through the model, from their age at treatment initiation to their time of death or until 100 years of age. The model consisted of eight health states: well; hip fracture; vertebral fracture; wrist fracture; other osteoporotic fracture; post-hip fracture; post-vertebral fracture; and dead. All patients began in the well-health state. In this model, 5% discounted rate, two-year maximum offset time, and persistence were adopted. Results: The total lifetime costs for alendronate and denosumab were USD 5,587 and USD 6,534, respectively. The incremental cost-effectiveness ratio (ICER) for denosumab versus alendronate was USD 20,600/QALY. Given the ICER threshold in Korea, the results indicated that denosumab was remarkably superior to alendronate. Conclusion: Denosumab is a cost-effective alternative to the oral anti-osteoporotic treatment, alendronate, in South Korea.

Purpose: This study aimed to evaluate the efficacy of simultaneous computed tomography (CT) and quantitative CT (QCT) in patients with osteoporotic hip fracture (OHF) by analyzing the osteoporosis detection rate and physician prescription rate in comparison with those of conventional dual-energy X-ray absorptiometry (DXA). Materials and Methods: This study included consecutive patients older than 65 years who underwent internal fixation or hip arthroplasty for OHF between February and May 2015. The patients were assigned to either the QCT (47 patients) or DXA group (51 patients). The patients in the QCT group underwent QCT with hip CT, whereas those in the DXA group underwent DXA after surgery, before discharge, or in the outpatient clinic. In both groups, the patients received osteoporosis medication according to their QCT or DXA results. The osteoporosis evaluation rate and prescription rate were determined at discharge, postoperative (PO) day 2, PO day 6, and PO week 12 during an outpatient clinic visit. Results: The osteoporosis evaluation rate at PO week 12 was 70.6% (36 of 51 patients) in the DXA group and 100% in the QCT group (P<0.01). The prescription rates of osteoporosis medication at discharge were 70.2% and 29.4% (P<0.001) and the cumulative prescription rates at PO week 12 were 87.2% and 60.8% (P=0.003) in the QCT and DXA groups, respectively. Conclusion: Simultaneous CT and QCT significantly increased the evaluation and prescription rates in patients with OHF and may enable appropriate and consistent prescription of osteoporosis medication, which may eventually lead to patients' medication compliance.

Purpose: The purpose of this study was to investigate the incidence of osteoporosis and falls and their consequences, and to identify predictors of fracture risk in the postmenopausal women. Methods: A total of 687 postmenopausal women were recruited through a stratified convenience sampling. A structured questionnaire was used to obtain osteoporosis and fall history and details of their most recent fall. To predict fracture risk factors, we collected demographic and physical health variables related osteoporosis and fall. Fracture risk was measured by FRAX$^{(R)}$ to calculate 10-year probability of major osteoporotic and hip fracture. Results: The prevalence of osteoporosis was 22.1%, and 66.4% of them had treatments for osteoporosis. The incidence of falls during the past year was 19.2% and 38.6% of those who fell suffered consequent fractures. Women with history of osteoporosis and falls were significant predictors of 10-year probability of major osteoporotic and hip fracture. Other significant predictors were history of fracture, chronic disease, surgical menopause, lower BMI, poorer perceived health and no job. Conclusion: It appears that history of osteoporosis and falls are main predictors of fracture risk. Nursing assessment should be performed by detail history taking for osteoporosis, fall, chronic disease, and fracture to screen fracture risk group among postmenopausal women.

목적: WHO(world health organization)에서 10년 내 골절 위험도라는 새로운 개념의 FRAX (fracture risk assessment) Tool을 2008년 초에 발표하였다. FRAX에서는 기존의 골절위험도와는 달리 여러 가지 위험인자가 고려되었다. 본 연구에서는 골절 위험인자 변화에 따른 골절 위험도를 알아보고자 한다. 대상 및 방법: 부산대학교 병원에서 50~60세의 여성 수검자 50명을 대상으로, GE사의 Lunar-prodigy로 골밀도를 측정하였다. 개인의 연령, 체중, 키를 바탕으로 대퇴경부의 T-score를 산출하였다. 골절 위험인자를 고려하지 않은 T-Score에서의 골절위험도를 대조군으로 하였다. 골절의 경험유무, 골절의 가족력(부모에 한함), 현재의 흡연 여부, 당질코르티코이드의 사용유무, 류마티스 관절염의 유무, 이차성 골다공증의 유무, 알콜의 평균섭취량의 7가지 항목을 실험군으로 하여 각각의 항목을 하나가 '유'이면 나머지는 모두 '무'로 하여 골절위험도를 비교하였으며, 골절위험도는 신체 주요부위 골절과 대퇴경부의 골절로 나누어 결과를 산출하였다. 통계는 SPSS 12.0의 t-test를 사용하였다. 결과: 대조군과 실험군 간의 골절위험도의 평균증가율은 먼저 신체 주요부위와 실험군을 알아보면 골절의 경험 -74% 증가, 골절의 가족력 -96% 증가, 흡연 -2% 증가, 당질코르티코이드 사용 -61% 증가, 류마티스 관절염 -29% 증가, 이차성 골다공증 -0.18% 감소, 알콜의 섭취 -20% 증가하였다. 대퇴골 경부와 실험군은 골절의 경험-84% 증가, 골절의 가족력 -5% 증가, 흡연 -72% 증가, 당질코르티코이드의 사용-84% 증가, 류마티스관절염 -40% 증가, 이차성 골다공증 -1.69% 감소, 알콜의 섭취 -52%가 증가하였다. 결론: 신체 주요부위와 대퇴골 경부에서 위험인자 항목마다 골절위험도의 각기 다른 증가율을 보였으나 이차성 골다공증의 경우에는 유의확률이 낮아 연관성이 다소 떨어짐을 확인하였다. 이와 더불어 각각의 인자가 신체 주요부위에서의 골절위험도를 높이는 비중과 대퇴골경부에서의 골절위험도를 높이는 비중에서 기여도가 다름을 알 수 있었다.

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.

Objectives : The reproductive history of women has been suggested to have a possible influence on the risk of osteoporotic fractures. The purpose of this study was to assess the association between reproductive history and hip fractures in the elderly women. Methods : The study subjects were drawn from women members of the Korean Elderly Pharmacoepidemiologic Cohort (KEPEC), aged 65 years or over, whose reproductive histories were available, and who were beneficiaries of the Korea Medical Insurance Corporation (KMIC) in 1993 and lived in Busan city, Korea. The information on reproductive histories, and possible confounders, were collected from mailed questionnaires. Potential hip fracture cases were collected from the claims data obtained between 1993 and 1998, with a hospital survey conducted to confirm the final diagnoses. Rate ratios and their 95% confidence intervals, were calculated using a Cox's proportional hazard model. Results : Following up 5,215 women for 6 years, 51 cases were confirmed with hip fractures. When adjusted for age, weight and physical activity, the rate ratio of hip fractures in women who had given birth three or more times was 0.56 (95% CI: 0.25-1.25), compared with those who had given birth two or less times. When adjusted for age, number of births, weight and physical activity, the rate ratio in women who first gave birth when younger than 22 years was 0.60 (95% CI: 0.34-1.08) compared with those who had giving birth at 22 years or older. Conclusions : According to these findings, an early age when first giving birth might decrease the risk of hip fractures in elderly Korean women.

목적: 근감소증에 중요한 요소인 척추 주변 근육 감소를 수치화한 총 지방 침윤율(total fat infiltration rate, TFI rate)과 골다공증성 척추 압박 골절(osteoporotic vertebral compression fracture) 및 관련 수치와의 상관 관계를 찾는 것을 목표로 하였다. 대상 및 방법: 2012년 1월부터 2016년 12월까지 요추의 압박 골절 진료를 본 환자들 중 1) 골밀도(bone mineral density, BMD) T score -2.5 g/cm² 미만으로 골다공증을 진단받고, 2) 요추 골절로 경피적 척추성형술(vertebroplasty) 또는 경피적 풍선척추성형술(kyphoplasty)을 받았으며, 3) 요추의 한 분절만 골절된 4) 1년 이상 추시한 환자 98명을 대상으로 후향적 연구를 시행하였다. TFI는 Image J 프로그램으로 자기공명영상을 분석하여 확인하였다. 이를 바탕으로 다열근(multifidus) 및 척추기립근(erector spinae)의 TFI와 골다공증 요소들과의 연관성을 분석하였다. 결과: 다열근및 척추기립근의 평균 TFI는 14.66±10.16이었다. 척추 BMD는 고관절 BMD와 통계적으로 유의한 양의 상관 관계를 보였으나 TFI와 음의 상관 관계를 보였다. 고관절 BMD는 체질량지수(body mass index)와 유의한 양의 상관 관계를 보였다. 또한 비타민 D 수치는 척추 BMD와 고관절 BMD에서 모두 양의 상관 관계를 보였으나, TFI와는 음의 상관 관계를 보였다. 결론: 근육량은 근감소증 환자뿐만 아니라 골다공증 환자의 치료에 있어서도 도움이 되므로 주의깊게 보아야 할 것이다. 또한 비타민 D를 증가시키는 것은 근육 위축의 진행을 늦출 수 있으므로 이로써 골절을 예방하는 효과를 가져올 수 있다.

It is well defined that osteoporosis is an age related disorder and associated with decreased bone mass. It is one of the most important disease lacing the aging population because of its association with fracture of the hip, vertebrae and distal radius. The disease provoke a significant economic burden and major public health problem of an elderly. The life-time risk of hip fracture in white women is approximately 15% which is equal to the combined risk of breast, uterine, and ovarian cancer. Despite its deleterious effect on women's health, knowledge of the epidemiology of osteoporosis in Korea is only beginning. 1970 in Korea has non as the crossover period between the chronic and an Infectious diseases. As the result, the infant mortality declined and an elderly population in Korea increased significantly in the past decade, The average life expectancy of women in Korea is now about 75 years. Thus, the majority of Korean women will spend approximately one-third of their life in the postmenopause state. Therefore, better understanding of bone metabolism and fracture incidence in Korean population is a great interest for the medical community as well as for public health. Currently, no population based epidemiologic data are available to support the incidence of osteoporotic fractures in Korea. However, available data suggest that significant declining of bone mineral density (BMD [g/$cm^2$]) has been occurring in Korean women after menopause. In same population, peak BMD was observed around 33-39 years of age and continue to decline thereafter. An accelerated bone losses occur after the menopause and the average loss is approximately 13% within 15 years from the menopause. The incidence of fracture was highly correlated with an age and bone mineral density. The mean age of menopause in Korean women was 47 years and this age appears to getting younger when analyzed by the birth cohort. An earlier menopausal age and increase life expectancy place Korean women at increase risk for osteoporosis and bone fracture. Korean or Asian women are no longer protected from the risk of bone fracture. Therefore, an early prevention or intervention schemes are essential before the outbreak of osteoporosis and/or fracture occurs in Korean or Asian women.
