External fixation is more suitable for intra-articular fractures of the distal radius in elderly patients

The purpose of this study was to compare the functional outcomes, psychological impact, and complication rates associated with external fixation and volar or dorsal plating in relation to the functional parameters following treatment of intra-articular fractures of the distal radius （IFDR） in patients older than 65 years. We hypothesized that using volar or dorsal plating would improve functional outcomes, but that it would be associated with more complications and equivalent functional outcomes when compared with the external fixation group. A total of 123 consecutive patients suffering from IFDR were recruited into the study. The patients were measured for clinical, radiological, and psychosocial functioning outcomes and were followed up after I week and 3, 6 and 12 months. After 3 months, the plating group had better pronation （P = 0.001）, supination, （P = 0.047） and extension （P = 0.043） scores. These differences were somewhat attenuated by 6 months and disappeared at I year. The plating group had a greater occurrence of wound infection （P = 0.043）, tendonitis, （P = 0.024） and additional surgery compared with the external fixation group. The only TNO-AZL Adult Quality of Life scores in the plating group that were lower than those in the external fixation group were in the ＂gross motor＂ category （walking upstairs, bending over, walking 500 yards; P = 0.023）. Internal fixation was more advantageous than external fixation in the early rehabilitation period; after I year the outcomes were similar. The plating group showed significantly higher levels of wound infection and tendonitis and had a greater need for additional surgeries.

Age-friendly Streets Based on Street View Images: A Case Study of Beijing Pingguoyuan Street

Many urban block planning in China can not be well satisfied for the elderly’s quality of life and activity demand.The study of urban block travel senility is helpful to discover the real needs of the elderly for walking space,distinguish the senility level of public walking space,and promote the development of the construction of the senility city.Based on literature research,this paper firstly summarizes the needs of the elderly in the pedestrian space in terms of their traffic feelings and visual experience,and then carries out image semantic segmentation operations on street view images by taking street view images,image semantic segmentation and other research methods.Factor division was carried out on the summary data of the elderly walking space experience,and scoring was carried out according to the elements in the image.Finally,it was found that the development of the elderly walking space in Pingguoyuan Street through the street view pictures was of great significance.
