골밀도검사는 뼈가 어느 정도 단단한가를 측정하는 검시다. 대개 요추 및 골반 뼈에 대한 검사를 수치화해 이를 정상, 골감소증, 골다공증으로 분류하게 된다. 우리나라 50세 이상 여성의 32.6% 남짓에서 발병하는 골다공증은 완치가 어려우므로 예방하는 것이 최선이다.

주위의 지인들로부터 골다공증에 대하여 여러 가지 질문을 받곤 한다. 골다공증이란 무엇이고, 그 원인은 무엇이며, 검사방법과 증상 등은 어떻게 되는지 자세히 묻는다. 하지만 정작 기대하는 것은 어떻게 하면 골다공증을 막을 수가 있는가에 대한 적절한 대답이다. 이에 대한 정답은 너무나 쉽고 명확하다.

향후 21세기는 지금껏 경험해 보지 못한 고령화 사회로서, 골다공증은 심혈관 질환 및 당뇨병에 이어 가장 중요한 노인 질환으로 대두 되어질 것이다. 그러므로 골다공증에 대한 조기 진단과 예방을 위한 진단방법은 매우 중요하나 잘못된 진단으로 조기발견을 놓칠 수 있게 된다. 여러장비 중 Radiographic Absorptiometry는 단순 X선 촬영을 통해서 피질골(손의 metacapal bone)의 두께를 측정하는 방법으로 간단하지만 약간의 오류를 갖고 있어 검사부위의 변환을 통해 결과값을 연구하고자 한다.

골다공증은 뼈의 화학적 조성에는 변화가 없고 단위 용적 내의 물량 감소를 초래해 경미한 충격에도 쉽게 골절을 일으키는 질환으로 뼛속에 구멍이 많아져 골밀도가 저하된 상태를 말한다. 우리 몸의 뼈는 소아기와 청소년기를 거쳐서 점차 단단해지고 20~30대에 생애 중 최대골량을 형성하며, 나이가 들수록 골량이 서서히 줄어들다가 폐경기 이후 여성에서 매우 빠른 속도로 골량이 감소한다. 이러한 골다공증은 대부분 증상 없이 조용히 진행되다가 골절이 나타난 후에야 발견된다. 골다공증이 진행된 후에는 허리가 구부러지고 경미한 충격에도 골절을 일으키는데 주로 척추, 대퇴골 늑글 등의 골절이 흔히 발생한다.

골다공증은 골강도에 문제가 생겨서 골절 위험이 커지는 질환이다. 골강도는 골밀도와 골의 질로 결정되는데, 골강도의 70%는 골량 즉, 골밀도에 의존한다. 따라서 골밀도는 골다공성 골절을 가장 잘 예측할 수 있는 지표가 된다.

Purpose: To investigate the prevalence of osteoporosis or osteopenia via dual-energy X-ray absorptiometry bone mineral density (DEXA BMD) in adult males who showed radiolucent lumbar vertebra on the plain radiographs. Materials and Methods: The DEXA BMD values of 98 adult males, who showed radiolucent vertebrae on plain X-rays, were compared with those of the control group (n=168) and osteoporosis-related fracture group (n=113) by statistical analysis. The World Health Organization (WHO) method (lower value between the mean lumbar and femur neck) and the Hansen's method (lowest lumbar vertebra) were used to determine osteoporosis. Results: The mean and standard deviation of the BMD value of each group was -1.4 (±1.2) in the suspicious group, -0.8 (±1.1) in the control group, and -2.4 (±1.0) in the fracture group, respectively; the difference was statistically significant. Using the WHO method, the prevalence ratio of osteoporosis was 17.3% in the suspicious group, 8.3% in the control group, and 45.1% in the fracture group, respectively. Osteopenia was observed in 40.8% of the suspicious group. Hansen's method (lowest lumbar vertebra) revealed the prevalence of osteoporosis in 30.6% of the suspicious group, 17.9% of the control group, and 62.0% of the fracture group. Conclusion: Approximately 17.3% of the suspicious group was diagnosed with osteoporosis, and 40.8% were osteopenic by a confirmative BMD study (WHO criteria) among the adult males showing apparent radiolucency on plain X-rays. The control group also showed an 8% prevalence of osteoporosis. These results suggest that males also are vulnerable to osteoporosis. Therefore, a BMD study should also be used for males, especially for the people showing lumbar vertebrae with radiolucent features.

Background and Objectives: The study was performed to investigate the status of osteoporosis for S electronics workers in H hospital of G city form April 21 to May 31 2008. Material and Method: The result of this research is following. Results: As results of osteoporosis analysis based on general characteristic, for men, something of 21 was the most frequent and osteoporosis of 13 was the second most frequent, and for women, good of 12 was the most frequent and care was the second most. The results concludes that men have more problems with osteoporosis that women have. In age of 40 years or more, care level of 24(88.9%) was the most frequent and good level of 15 people was the second most. This result concludes that age of 40 year is target subjects for care. In position, senior has 14 people who have care level(42.4%) and 8 people(24.2%)of osteoporosis level. The result concludes than the senior has more osteoporosis than the employ has. Conclusion: In conclusion, the age, position, weight are related to osteoporosis.

Generally, the osteoporosis of a middle-aged women have been reported that was a high risk in underweight, but the obese women have feasible osteoporosis. Therefor, the subjects were 120 middle-aged women that were diagnosed with osteoporosis in the bone mineral densitometer (BMD), this study was done for the purpose of analyzing the relationship between osteoporosis and body mass index (BMI) of the middle-aged women. We were determined BMI which was less than 18.5 underweight, 18.5 to 22.9 normal, 23.0 to 24.9 overweight, 25.0 to 29.9 obesity and extremely obesity were more than 30. When we examined the BMI distribution of the subjects, it was 2 women (1.7%) for underweight, 18 women (15.0%) for normal, 19 women (15.8%) for overweight, 75 women (62.5%) for obesity and 6 women (5.0%) for extremely obesity. Also, the relationship between osteoporosis and BMI of the subjects, it was the osteoporosis in 13 cases out of 18 (72.2%) with normal, in 14 case out of 19 (73.7%) with overweight, in 63 case out of 75 (84%) with obesity, in 5 case out of 6 (83.3%) with extremely obesity, besides, the osteoporosis usually marks the highest in a BMI with obesity. In conclusion, the result of analyzing the relationship between osteoporosis and BMI, we found out that the osteoporosis of the middle-aged women was high risk with obesity, and that was mostly higher the osteopenia rather than osteoporosis.

In this study, a finite element analysis and a vibration test were performed to estimate the natural frequencies of mouse femurs with osteoporosis. Three groups of the femurs include the osteoporotic group, the treated group and the normal group. For the finite element analysis, the micro finite element model of the femur was reconstructed using the Micro-CT images and the Voxel mesh generation algorithm. In the vibration test, the natural frequencies were measured by the mobility test. from the results, the averaged natural frequencies in the osteoporotic group were the highest, followed by those in the treated group. The finite element models were validated within 15% errors by comparing the natural frequencies in the finite element analysis with those in the vibration test. The developed Micro-CT system, the Yokel mesh generation algorithm, the presented finite element analysis, and vibration test could be useful for the investigation of the structural change of the bone tissue, and the diagnosis and the treatment in the osteoporosis.
