- Osteoporosis represents reduced amount of bone mass per unit volume as compared with controls of the same age and sex. In this condition, bone mineral density decreases and the skeleton becomes more prone to fracture. The purpose of this study was to show how bone mineral densities of the femoral neck area decrease with aging, to in vestigate the relationship between the bone mineral densities of the control and fracture group, and to obtain fracture threshold values. This report observed BMD of femoral neck region in femoral neck and intertrochanteric fracture group was less than that of control group and the differences were significant. We measured and evaluated BMD of femoral neck region by DEXA in 234 normal volunteers(99 men and 135 women), in 105 patien ts with femoral neck fracture(41 men and 64 women) and in 103 patients with intertrochanteric fracture(40 men and 63 women) above 50 years-old. Following results were obtained: 1. The average BMD of femoral neck region in control group, femoral neck fracture group and intertrochanteric fracture group were 0.751+/-0.030 g/cm2 in male and 0.661+/-0.089g/cm2 in female, 0.660+/- 0.031g/cm2 in male and 0.557+/-0.002g/cm2 in female and 0.661+/-0.008g/cm2 in male and 0.562+/-0.005g/cm2 in 2. The BMD of the control group and fracture group decreased with aging and were higher in men than in women and there were statistically significant difference(p<0.001). 3. There were statistically significant difference between BMD of the control group and BMD of the hip fracture group(p<0.005) but no significant differences between BMD of the femoral neck fracture group and intertrochanteric fracture group. 4. Fracture threshold of the hip fracture group were 0.815g/cm2(male:0.832g/cm2, female:0.733g/cm2) according to 95 percentile.

Abstract
- Forty-six patients who had had forty-nine calcaneal fractures were managed with closed reduction and a cast, closed reduction and axial pin fixation, and open reduction and internal fixation. The results were reviewed retrospectively, between twelve months and twenty-six months after the treatment, with criteria usued in assesssment of result by Salama30) and with plain radiographs. The purpose of this study were to analyze the relationship between the prognostic factors and post-treatment results. The results of treatment and prognostic factors obtained from this study were as follows. 1. The negative prognostic factors that were associated with an unsatisfactory out come were an age of more than fifty years, a greater body weight, work involving strenuous labor, subtalar incongruity, a decreased fibulocalcaneal space, and a decreased B hler-angle ratio of the fractured to the normal side. 2. Patients who had had a tongue-type fracture had a better result than those who had had a central depression fracture, while those who had had a central depression fracture had a better outcome than those who had had a comminuted fracture. 3. The length of the Achilles-tendon fulcrum, which is directly related to the calcaneal length, was not related to the outcome.
