The development of different entities of soft tissue sarcoma in one patient is rare. It usually affects head and neck or abdominal region, whereas those affecting the extremities are much rarer. We describe a patient with double primary presentation of liposarcoma and Ewing's sarcoma in extremity. This case implies that sarcoma patients are at increased risk of a second malignancy, and this implies a need to search for occult tumors during follow up.

Purpose : The aim of this study was to investigate the correlations between body compositions and bone mineral density in young women and postmenopausal women with low bone mineral density. Methods : Eleven young women (age, $25.85{\pm}1.96yrs$; height, $160.28{\pm}2.16cm$; weight, $56.89{\pm}9.66kg$) and ten postmenopausal women (age, $25.85{\pm}1.96yrs$; height, $160.28{\pm}2.16cm$; weight, $56.89{\pm}9.66kg$) with low bone density on femur neck were participated in this study. All subjects performed the measure of body composition and BMD on lumbar body and femur neck. Results : The results were as follows. Percent body fat, waist-hip ratio and body mass index(BMI) were significantly increased in postmenopausal women. BMD in lumbar body and femur neck were significantly decreased in postmenopausal women. There were negative strong correlation between BMD of the femur and age in young women. There were negative strong correlation between BMD of the femur and age or the years of menopause in postmenopausal women. There were positive strong correlation between BMD of the femur and BMD of lumbar body. Conclusion : Percent body fat and BMI were more increased in young women than in postmenopausal women. And there were negative strong correlation between BMD and age or the years of menopause in postmenopausal women.

Purpose: This study analyzed the bone mineral densities of the lumbar vertebrae and femurs of patients with ankle fractures to determine the correlation between ankle fractures and osteoporosis. Materials and Methods: From April 2002 to July 2014, one hundred consecutive ankle fracture patients with bone mineral density tests performed within post-traumatic one year were enrolled. The patients were divided into three age groups according to their age at the time of injury (group 1: <50, group 2: 50-69, group 3: ≥70). The types of ankle fractures were classified into unimalleolar, bimalleolar and trimalleolar fractures. The bone mineral density was analyzed using the T score, Z score, absolute value (g/cm²) of the lumbar spine (L1-L4), femur neck, femur intertrochanter, and total femur. Results: There were 3.2 times more females with ankle fractures than males, and the prevalence of osteoporosis according to age group was 0% in the group under 50 years, 24.2% in the 50 to 69-year-old group, and 15% in the group over 70 years. Osteoporosis was found in 30% of patients with a trimalleolar fracture in the 50 to 69-year-old group. In all patient groups, a lower age indicated a higher frequency of unimalleolar fractures. The relationship between the bone mineral density and the type of fracture is that the frequency of trimalleolar fracture increased with decreasing T score of the lumbar vertebrae and the absolute value of bone mineral density (g/cm²) and the Z score of the femur neck, but there were no other indicators. Conclusion: Among the 100 patients with ankle fractures, females were more common than males, because osteoporosis was less severe in males. The incidence of unimalleolar fracture was higher than that of trimalleolar fracture. On the other hand, the correlation between the ankle fractures and the bone mineral density of the femur and lumbar spine was not significant.

Purpose: To report two cases of bone tumors other than osteoid osteoma in the proximal femur and treated with percutaneous high frequency radioablation method. Cases: We reviewed two cases with intracortical chondroma and enchondroma in the femoral head retrospectively. The patient with intracortical chondroma was a thirty one year old woman and had suffered right hip pain of 1 year duration. The lesion was located in the head of right femur and treated with CT guided percutaneous high frequency radioablation after needle biopsy under general anesthesia. The symptom was gone immediately after the procedure and was discharged postop. 1 day. 15 months has passed without symptom recurrence. Second case having enchondroma, was 56 year old woman complaining of gluteal area pain for 3 months. Radiologic evaluation showed osteolytic lesion with sclerotic rim on the inferior portion of the left femoral head. She received a same therapy with CT guided radiofrequency ablation following needle biopsy. She reported dramatic pain relief after the procedure and was discharged postop. 1 day. No symptom has occurred for 3 months until now. Conclusion: We present 2 cases of bone tumor occurred in the hip joint area other than osteoid osteoma which were treated with CT guided radiofrequency ablation.

Purpose: A cross-calibration equation is needed to compare bone mineral density measured by different dual X-ray absoptiometry systems. We performed this study to establish appropriate cross-calibration equations between two different dual X-ray absorptiometry systems. Materials and Methods: Bone mineral density of anterior-posterior lumbar spine (L2-4 level) and femoral neck were measured in 109 women ($55{\pm}11yr$) using two different dual X-ray absorptiometry systems (Lunar EXPERT-XL and Hologic QDR 4500-A). Bone mineral density values measured by two systems, including area, bone mass content, bone mineral density and percentile of young normals were compared and cross-calibration equations between two systems derived. Results: The bone mineral density values of 109 women measured by Lunar system were $0.958{\pm}0.17g/cm^2$ at L2-4 and $0.768{\pm}0.131g/cm^2$ at femur neck, which were significantly higher ($13{\pm}6%$ at L2-4 and $19{\pm}7%$ at femur neck, p<0.001) than those ($0.851{\pm}0.144 g/cm^2$ at L2-4 and $0.649{\pm}0.108 g/cm^2$ at femur neck) by Hologic system. Bone mineral content and percentile of young normals measured by Lunar system were also significantly higher than those by Hologic system (p<0.001), whereas there was no difference in area (p>0.05). There was a high correlation between bone mineral density values of L2-4 and femoral neck obtained with both dual X-ray absortiometry systems (r=0.96 and 0.95, respectively). Cross-calibration equations relating the bone mineral density were Lunar= 1.1287${\times}$Hologic -0.0027 for L2-4 and Lunar= 1.1556${\times}$Hologic+0.0182 for femoral neck. Conclusion: We obtained cross-calibration equations of bone mineral density between Lunar EXPERT-XL and Hologic QDR 4500-A. These equations can be useful in comparing bone mineral density obtained by different dual X-ray absorptiometry systems.

Slipped capital femoral epiphysis(SCFE) is a disorder in which there is a gradual or acute disruption through the capital physeal plate. The physiolysis is through a widened zone of hypertrophy, which is weakened due to altered chondrocytic maturation and endochondral ossification. The cause or causes of SCFE remain uncertain. The association of obesity and adolescent age with growth rate are predisposing factors. The possibility that most patients with subclinical hormonal abnormality were proved. The goal of treatment of slipped capital femoral epiphysis is to restore the function of the hip and delay the development of degenerative osteoarthrosis by prevention of additional displacement of the epiphysis. We report 10 patients(12hips) with SCFE who were treated by surgical means and followed along for more than one year, at Yeungnam University Hospital, from 1989 to 1996. There were six boys and four girls. The average age at operation was 11.8 years. Seven cases occurred in the left hip, one case in the right and 2 cases had bilateral involvement, five cases had a history of minor trauma on affected hip. Among hormonally studied six patients, panhypopituitarism patient was one case; decreased testosterone, two; decreased growth hormone, two; and decreased thyroid hormone, one. According to clinical stage, two cases were the acute type; five cases, acute on chronic type; and three cases, chronic type. On the radiological grades of slipping, mild slippage were nine hips; moderate, one; and severe, two. The eleven hips were treated by pin fixation in situ, and one, by cuneiform osteotomy. On the average follow-up of 2.6 years, ten hips were excellent or good functional results, two hips were failure.

Background : There are many risk factors for osteoporosis in patients with chronic obstructive pulmonary disease(COPD). These include smoking, a low body mass index, insufficient exercise, and the use of glucocortcoids. However, there is lack of data on the incidence of osteoporosis according to the different glucocorticoid administration methods in patients with COPD. This study compared the incidence of osteoporosis according to the different administration methods of glucocorticoid. Methods : A matched case-controlled study (gender, age, cumulative steroid dose and pack-years of smoking) was conducted. Forty-five patients with documented COPD for at least a 3 year duration and a cumulative glucocorticoid dose above 1,000 mg were enrolled in study. The patients were classified into the following three groups. First, fifteen patients received continuous inhaled glucocorticoid with intermittent oral steroids but had no admission history due to an acute exacerbation(Group I). Secondly, fifteen patients received a multiple course of oral steroids with additional inhaled glucocorticoid but had no admission history due to their acute exacerbation(Group II). Lastly, fifteen patients received intermittent oral or inhaled glucocorticoids and had an admission history due to the acute exacerbation with intravenous steroid treatment for at least 2 weeks per year(Group III). The enrolled patients had apulmonary function test and bone densitometry performed at the lumbar spine and femoral neck. Results : The patients from Group III had significantly high incidence of osteoporosis in the lumbar and femoral neck compared to Group I and Group II (p<0.01). Conclusion : The incidence of osteoporosis in patients with COPD appears to be strongly affected by the method of steroid administration. This result suggests that intravenous steroid administration is strongly associated with the risk of osteoporosis.

The purpose of this study was to determine the evaluation parameters' osteoporosis predictability in accordance with measuring regions by analyzing the correlations between bone mineral density and trabecular patterns derived from different measuring regions. Experimental subjects were a total of 40 female patients after menopause aged over 40 years, and were classified into 20 control and 20 osteoporotic groups according to the T-score. Bone mineral density was measured on femoral neck, trochanter and ward's triangle by DEXA(Dual Energy X-ray Absorptiometry). We designated ROI(Region of Interest) with $50{\times}50$ pixel size on each measuring regions, and extracted trabecular patterns by using existing image processing method. We also selected a total of eight evaluation parameters that are categorized into structural(mean gray level, area, perimeter, thickness and terminal distance), skeletonized parameters(number, length) and fractal dimension. As a result, it was observed that area, perimeter, thickness, terminal distance, number, length and fractal dimension reflected the bone mineral density with high statistical validity(p<0.003). We also confirmed that the evaluation parameters could predict the osteoporosis more efficiently.
