유현승,조영호,박영보,하성수 대한고관절학회 2017 Hip and Pelvis Vol.29 No.2

Purpose: Atypical femoral fractures (AFFs) occur in two distinct part, subtrochanter and diaphysis. The aim of this study was to investigate the relationship between the lateral femoral bowing angle and the location of AFF. Materials and Methods: This study included a total of 56 cases in 45 patients who underwent surgical treatment between January 2010 and December 2015. For the diaphyseal and subtrochanteric AFFs, we evaluated the relationship between the anatomic location and lateral femoral bowing angle. Lateral femoral bowing angle was measured by two orthopaedic surgeons and average value of two calibrators was used in statistic analysis. Other variables like age, height, weight, body mass index and bone mineral density were also evaluated. We also calculated the cutoff value for the location of the fractures from the raw data. Results: The average lateral femoral bowing angle was 10.10。±3.79。(3。-19。) in diaphyseal group and 3.33。±2.45。(1.5。-11。) in subtrochanter group. Lateral femoral bowing angle was statistically significant in logistic regression analysis. According to the receiver operating characteristic curve, cutoff value for the location of the fracture was 5.25。. In other words, the femoral diaphyseal fractures are more frequent if the lateral femoral bowing angle is greater than 5.25。. Conclusion: The lateral femoral bowing angle is associated with the location of the AFFs and the cutoff value of lateral femoral bowing angle was 5.25。.

Is Taking an Antiplatelet Agent a Contraindication for Early Surgery in Displaced Femur Neck Fracture?

유현승,조영호,변영수,김민극 대한고관절학회 2015 Hip and Pelvis Vol.27 No.3

Purpose: The purpose of this study was to evaluate whether we have to stop the antiplatelet agents prior to hemiarthroplasty surgery in patients with displaced femur neck fractures to reduce postoperative complications. Materials and Methods: We enrolled forty-three patients with displaced femur neck fractures who were treated by bipolar hemiarthroplasty and were taking antiplatelet agents. Group I included 21 patients who discontinued antiplatelet agents and had delayed operations at an average 5.7 days and group II included 22 patients who had had early operations within 24 hours without stopping the antiplatelet agents. We compared the pre- and postoperative levels of hemoglobin, the volume of postoperative transfusion requirement and complications. Student’s t-test and chi-square test were used for statistical analysis. Results: The average differences between preoperative and postoperative hemoglobin was 1.4±0.4 g/dL decrease in group I and 2.1±0.5 g/dL decrease in group II (P<0.001). Patients who received a blood transfusion were 11 in group I and 13 in group II (P=0.66). Total number of blood transfusion was 13 pints in group I and 18 pints in group II (P=0.23). Pneumonia occurred in one patient in each group. Four pressure sores and three diaper rashes were developed in group I. But there were no patients requiring massive transfusion, reoperation due to hematoma and infection in each group. Conclusion: Although continuous taking of antiplatelet agents in displaced femur neck fracture is associated with an increased risk of postoperative bleeding, taking an antiplatelet agent itself is not a contraindication of early surgery.

Recent advances in wavefront shaping techniques for biomedical applications

Due to the highly inhomogeneous distributions of refractive indexes, light propagation in complex media such as biological tissue experiences multiple light scattering events. The suppression and control of multiple light scattering events are investigated because they offer the possibility of optical focusing and imaging through biological tissues, and they may open new avenues for diagnosis and treatment of several human diseases. In order to provide insight into how new optical techniques can address the issues of multiple light scattering in biomedical applications, the recent progress in optical wavefrontshaping techniques is summarized

소외계층 스포츠복지 지원체계 문제점의 내용분석: 다문화가정을 중심으로

For the neglected class, sports welfare plays a very important role to look away from the groups that can be discriminated and excluded, to improve the health and quality of life of individual members, and to social integration. In this study, 22 open-ended questionnaires of multicultural family members with limited social oppression and sports participation among the various neglected classes were analyzed. The problems of sports participation constraint, ie sports welfare support system, derived from this study are largely divided into four categories such as livelihood and language constraints, exercise programs, accessibility, and prejudice of surrounding people. Through this study, it is meaningful to find out what problems are occurring in the sports welfare support system of multicultural families among the neglected groups, and to provide various information in constructing the sports welfare support system of multicultural families . 소외계층에게 스포츠 복지는 차별받고 배제될 수 있는 집단에서 벗어나고, 구성원 개인의 건강과 삶의 질 향상, 그리고 사회통합까지 바라볼 수 있는 매우 중요한 역할을 담당하고 있다. 이 연구에서는 다양한 소외계층 중에서도 최근 사회적 억압과 스포츠 참여가 제한되고 있는 다문화가정 구성원 22명을 대상으로 개방형 설문조사를 수행하였고, 이를 토대로 스포츠 복지 지원체계 문제점에 대한 내용분석을 진행하였다. 이 연구에서 도출된 스포츠 참여 제약사항, 즉 스포츠 복지 지원체계 문제점은 크게 생계 및 언어제약, 운동 프로그램, 접근성, 주변인의 편견 등 네 가지로 범주로 구성되었고, 이를 구성하는 세부 내용들을 제시하였다. 이 연구를 통해 소외계층 중에서도 다문화가정의 스포츠 복지 지원체계에서 발생하는 문제는 무엇인가를 판단하고, 이를 통해 다문화가정의 스포츠 복지 지원체계를 구성하는 데에 있어 다양한 정보를 제공한다는 데에 의의를 지닌다.

This study was conducted to investigate the effects of 12-week Pilates exercise to prevent falls on the elderly fitness, balance, and fall index of elderly women. The study subjects were selected from 12 female Pilates Exercise Groups (PEG) and 12 Control Groups (CG). The study design was conducted as a pre- and post-similar experimental study and the exercise program was conducted 3 times a week, 60 minutes, and 12 weeks. The functional fitness test for the elderly was the Senior Fitness Test (SFT), and the balance capacity test was performed using Tetrax to measure the weight distribution index (WDI), stability index (ST), and fall index (FI). For the data processing of this study, two-way ANOVA with repeated measures was performed using SPSS/ver 21.0, and the significance level was set to α=.05. As a result of the study, the elderly group with Pilates showed significant improvement in lower extremity muscle strength, upper extremity muscle strength, lower extremity flexibility, and whole body endurance. In addition, the stability index (ST) had a significant effect on the PC, HB, and the weight distribution index (WDI) on the HR attitude among the measured attitudes, and a significant effect on the fall index (p<.05). The results of these studies proved that the Pilates exercise program is a safe and effective exercise program to improve physical fitness and balance for older women and lower the risk of falls. 본 연구는 여성노인을 대상으로 낙상예방을 위한 12주간의 필라테스 운동이 노인체력, 균형감각 및 낙상지수에 미치는 영향을 알아보기 위해 실시하였다. 연구대상자는 24명의 여성노인으로 필라테스 운동군(Pilates Exercise Group; PEG) 12명, 대조군(Control Group; CG) 12명으로 선정하였으며, 연구 설계는 사전, 사후 유사 실험연구로 진행하였고, 운동 프로그램은 주3회, 60분, 12주 동안 진행하였다. 노인 기능체력 평가는 노인체력검사(Senior Fitness Test, SFT)로, 균형능력 평가는 Tetrax를 이용하여 체중분포지수(WDI)와 안정성지수(ST) 그리고 낙상지수(FI)를 측정하였다. 본 연구의 자료처리는 SPSS/ver 21.0을 이용하여 이원반복측정 변량분석(two-way ANOVA with repeated measures)을 실시하였고, 유의수준은 α=.05로 설정하였다. 연구결과 필라테스 적용 노인 그룹은 노인체력 중에서 하지근력, 상지근력, 하지유연성, 전신지구력에서 유의한 향상을 보였다. 또한 안정성지수(ST)는 측정자세 중 PC, HB에서, 체중분포지수(WDI)는 HR자세에서 유의한 효과가 나타났고, 낙상지수에서도 유의한 효과 나타났다(p<.05). 이러한 연구결과는 필라테스 운동프로그램이 여성노인의 체력과 균형감각을 향상시키고 낙상위험지수를 낮추는데 안전하고 효과적인 운동프로그램임을 증명하였다.
