This work consists of a series of experiments which were made in order: a) to examine the possible alterations of blood flow to the reduced femoral heads of rabbits, after inducing a closed dislocation of their hips and b) to determine the influence of the early or late reduction of the dislocated femoral heads on their blood flow. The estimations of blood flow to the normal and reduced femoral heads were made using radioactive microspheres. The findings are as follows: a) The blood flow of the femoral heads of the reduced hips was never interrupted completely. b) The initially decreased femoral head blood flow progressively increased, in association to the time elapsed from the reduction. c) No statistically significant difference was found in the femoral head blood flow between hips reduced in early and those reduced late. d) Pure traumatic dislocation of the hip can only rarely be the cause of aseptic necrosis of the femoral head.
a）在诱导兔髋关节闭合性脱位后，检查流向其股骨头缺血的血流可能发生的变化；b）确定脱位股骨头早期或晚期复位对其血流的影响。使用放射性微球对正常和缺血股骨头的血流进行评估。结果如下：a）复位髋关节的股骨头血流从未完全中断。b）最初减少的股骨头血流逐渐增加，与复位后经过的时间相关。c）早期复位和晚期复位的髋关节之间，股骨头血流未发现统计学上的显著差异。d）单纯创伤性髋关节脱位很少能成为股骨头无菌性坏死的原因。
