The purpose of this study was to compare nonbridging external fixators (group NB) with bridging external fixators (group B) in the treatment for unstable distal radius fractures. The subjects consisted of 84 patients, 42 in each group. Mean patient age was 64.0 years in group NB and 59.6 years in group B. According to Saito's classification, most fractures were of the comminuted Colles type. No bone graft was made in group NB. Patients of group B showed serious reflex sympathetic dystrophy (RSD). On Saito's evaluation criteria, the proportion of patients evaluated as "good" or better was 100% in group NB and 95.6% in group B. This finding can be taken as evidence that group NB patients showed better results.

The purpose of the present study was to evaluate the profiles of the bone strength of rats treated from infancy with various drugs. Young female Sprague-Dawley rats were classified into five groups according to the composition of their diets. They underwent resection of their femurs for a three-point flexion test and an impaction test at 6, 8, 12, and 16 months of age. A microcomputed tomography unit was used to evaluate the microstructure of their femoral condyles at 16 months of age. The diet given to the rats in the control group contained 0.5% Ca. The rats in groups A, B, C, and D were placed on the following regimens, respectively: vitamin K mixed diet, vitamin D oral administration, 1.8% Ca-fortified diet, and 1.8% Ca-fortified diet plus vitamin K and vitamin D. In the impaction tests conducted on the rats at each age, the results from groups A and B were nearly the same as those from the control group. At 16 months of age, the rats in groups C and D had significantly higher test results than those in the control group. In the three-point flexion tests at 16 months of age, the results from groups A, B, and C were nearly the same as those from the control group. The results from group D, however, showed a significant increase. Examination of the microstructure of the femoral condyles at 16 months of age revealed controlled destruction of the trabecular structure in groups C and D. These findings suggest that supplementing the diet from infancy with Ca, vitamin K, and vitamin D might prevent bone fractures due to osteoporosis.
