Objectives: This study was conducted to find out risk factors related to elderly hip fracture, so that the result could provide basic data to establish prevention programs for hip fracture among the elderly. Methods: The data were collected from 199 cases hospitalized in 4 university hospitals in Pusan from January, 1996 to December, 1998, 193 healthy controls who visited elderly facilities in Pusan. The data were obtained from medical records and by using questionnaires through telephone contact or direct personal interview with the subjects or their family, and were analyzed for 2-test and multiple logistic regression. The risk factors were shown with odds ratios and their 95% confidence intervals. Results: In univariate analysis, the odds ratio of hip fracture risk was estimated to be 1.9 for the elderly aged 75 years as compare with those aging less than 65 years; 42 for those with job as compared with those without job; 3.3 for those with more than 6 children as compared with those with one or two children. For the variables related to physical characteristics, small height (p=0.015), light weight (p=0.000), and low BMI (p=0.014) were risk factors for elderly hip fracture. Sane variables related to health, such as previous history of illness (OR=3.3.), abnormal blood pressure (OR=1.6), previous fracture history (OR=22), lower limbs weakness (OR=12.1) and gait disturbance (OR=42.6), were significantly associated with the risk of hip fracture. In multiple logistic regression, risk factors for hip fracture were age, having job, lower limb weakness and previous history of illness. The adjusted odds ratios of hip fracture risk among the elderly were age (OR=1.1), having jobs (OR=11.7), weak lower limb (OR=10.8) and previous history of illnesses (OR=3.3), respectively. Conclusion: This study suggests that the plan for improving the daily living environment for the elderly systematically should be implemented to avoid the chances of fall, and that programs encouraging to practice regular exercise for physical activity and to promote health of the elderly should be developed.

Background: Bone fractures are high in elderly patients with type 2 diabetes mellitus (T2DM). Hyperglycemia and chronic kidney disease may increase the risk of fracture prevalence via altered bone metabolism, but whether glycemic control and kidney function are associated with the risk of fracture prevalence remains unclear. This study evaluated the relationship between glycemic control and baseline estimated glomerular filtration rate (eGFR) and risk of fracture prevalence in older and middle-aged patients with T2DM. Methods: Patients who underwent a general medical check-up between 2009 and 2013 were selected from the Korean National Health Insurance Sharing Service records. Chi-square test and multiple logistic regression analysis were used to assess the relationship between glycemic control and eGFR and risk of fracture prevalence. Results: Cumulative fracture prevalence were higher in patients with T2DM, irrespective of whether they had tight or less stringent glycemic control (fasting blood glucose [FBG] ${\geq}110mg/dL$). After adjustment for baseline age and FBG, tight and less stringent glycemic control was significantly associated with increased adjusted risk of fracture prevalence in middle-aged patients with T2DM (OR=1.13, 95% CI, 1.05-1.21, p=0.0005 vs OR=1.13, 95% CI, 1.06-1.20, p=0.0001), but not in older patients. Baseline eGFR was not significantly related to fracture prevalence in either older or middle-aged patients. Conclusion: Less stringent glycemic control significantly increased the adjusted risk of fracture prevalence in middle-aged patients with T2DM. Further studies are needed to confirm the effect of tight glycemic control on fracture prevalence.

Purpose: We perform an analysis of infection risk factors for fracture patients and confirm that the risk factors reported in previous studies increase the risk of actual infection among fractured patients. In addition, injury severity score (ISS) which is used as an evaluation tool for morbidity of trauma patients, confirms whether there is a relationship with infection after orthopedic fracture surgery. Methods: We retrospectively reviewed 1,818 patients who underwent fixation surgery at orthopedic trauma team, focused trauma center from January 1, 2015 to December 31, 2017. Thirty-five patients were infected after fracture surgery. We analyzed age, sex, open fracture criteria based on Gustilo-Aderson classification 3b, anatomical location (upper extremity or lower extremity) of fracture, diabetes, smoking, ISS. Results: Of 1,818 patients, 35 (1.9%) were diagnosed with postoperative infection. Of the 35 infected patients, nine (25.7%) were female and five (14.0%) were upper extremity fractures. Three (8.6%) were diagnosed with diabetes and eight (22.8%) were smokers. Thirteen (37.1%) had ISS less than nine points and six (17.1%) had ISS 15 points or more. Of 1,818 patients, 80 had open fractures. Surgical site infection were diagnosed in 12 (15.0%) of 80. And nine of 12 were checked with Gustilo-Aderson classification 3b or more. Linear logistic regression analysis was performed using statistical analysis program Stata 15 (Stata Corporation, College Station, TX, USA). In addition, independent variables were logistic regression analyzed individually after Propensity scores matching. In all statistical analyzes, only open fracture was identified as a risk factor. Conclusions: The risk factors for infection in fracture patients were found to be significantly influenced by open fracture rather than the underlying disease or anatomical feature of the patient. In the case of ISS, it is considered that there is a limitation. It is necessary to develop a new scoring system that can appropriately approach the morbidity of fracture trauma patients.

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.

Recent clinical studies have shown that computer navigation for total knee arthroplasty (TKA) provides improved component alignment accuracy. However, femoral stress fracture after computernavigated TKA have been reported due to the pin hole and we hypothesized that osteoporosis would be one of the key factors in pin hole fracture after computer-navigated TKA. We investigated the von-Mises stress around the femoral pin-hole for different elastic modulli and ultimate stresses and four different pin penetration modes to understand the aging effect on femoral stress fracture risk after computer-navigated TKA by finite element analysis. In this study, aging effect was shown to increase the femoral stress fracture risk for all pin penetration modes. Especially, aging effect was shown dramatically in the transcortical pin penetration mode.

Objectives: To evaluate the risk of fractures related with zolpidem in elderly insomnia patients. Methods: Health claims data on the entire South Korean elderly population from January 2005 to June 2006 were extracted from the Health Insurance Review and Assessment Service database. We applied a case-crossover design. Cases were defined as insomnia patients who had a fracture diagnosis. We set the hazard period of 1 day length prior to the fracture date and four control periods of the same length at 5, 10, 15, and 20 weeks prior to the fracture date. Time independent confounding factors such as age, gender, lifestyle, cognitive function level, mobility, socioeconomic status, residential environment, and comorbidity could be controlled using the case-crossover design. Time dependent confounding factors, especially co-medication of patients during the study period, were adjusted by conditional logistic regression analysis. The odds ratios and their 95% confidence intervals (CIs) were estimated for the risk of fracture related to zolpidem. Results: One thousand five hundred and eight cases of fracture were detected in insomnia patients during the study period. In our data, the use of zolpidem increased the risk of fracture significantly (adjusted odds ratio [aOR], 1.72; 95% CI, 1.37 to 2.16). However, the association between benzodiazepine hypnotics and the risk of fracture was not statistically significant (aOR, 1.00; 95% CI, 0.83 to 1.21). Likewise, the results were not statistically significant in stratified analysis with each benzodiazepine generic subgroup. Conclusions: Zolpidem could increase the risk of fracture in elderly insomnia patients. Therefore zolpidem should be prescribed carefully and the elderly should be provided with sufficient patient education.

Purpose: This study aims to establish a theoretical framework for the fall prevention behavior improvement program by verifying the associations between fracture risk, fall risk perception, and fall prevention behaviors in women with osteoporosis. Methods: A survey was conducted in 122 women who were diagnosed as osteoporosis by having T-score of the femur bone density below -2.5 standard deviation from the bone density examination performed in 2 orthopedic clinics located in B metropolitan city between July 2014 and September 2014. The risk of fracture, level of fall risk perception, and fall prevention behaviors were measured. Results: Fall risk perception had a complete mediating effect on the relationship between the fracture risk and fall prevention behaviors in women with osteoporosis. Conclusion: The perception of fall risk is important to enhance fall prevention behaviors in women with osteoporosis, and the development of various education programs to improve awareness of fall risk is needed.

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.

Purpose: To evaluate the risk of vertebral compression fracture (VCF) after conventional radiotherapy (RT) for colorectal cancer (CRC) with spine metastasis and to identify risk factors for VCF in metastatic and non-metastatic irradiated spines. Materials and Methods: We retrospectively reviewed 68 spinal segments in 16 patients who received conventional RT between 2009 and 2012. Fracture was defined as a newly developed VCF or progression of an existing fracture. The target volume included all metastatic spinal segments and one additional non-metastatic vertebra adjacent to the tumor-involved spines. Results: The median follow-up was 7.8 months. Among all 68 spinal segments, there were six fracture events (8.8%) including three new VCFs and three fracture progressions. Observed VCF rates in vertebral segments with prior irradiation or pre-existing compression fracture were 30.0% and 75.0% respectively, compared with 5.2% and 4.7% for segments without prior irradiation or pre-existing compression fracture, respectively (both p < 0.05). The 1-year fracture-free probability was 87.8% (95% CI, 78.2-97.4). On multivariate analysis, prior irradiation (HR, 7.30; 95% CI, 1.31-40.86) and pre-existing compression fracture (HR, 18.45; 95% CI, 3.42-99.52) were independent risk factors for VCF. Conclusion: The incidence of VCF following conventional RT to the spine is not particularly high, regardless of metastatic tumor involvement. Spines that received irradiation and/or have pre-existing compression fracture before RT have an increased risk of VCF and require close observation.
