9 immature pigs (age: 8-12 weeks) underwent longitudinal traction with 10%, 30%, and 50% body weight followed by overhead traction with 10% and 30% body weight. Microcirculation of the femoral head was monitored by a laser-doppler flow probe and macrocirculation within the lateral circumflex artery by an ultrasonic perivascular transit time flow probe. Changes in blood flow during each traction period were compared to the preceding resting period and expressed in percentages. With any type of longitudinal and overhead traction a trend towards an improvement in micro-and macrocirculation of the hip joint was observed although no significant differences could be detected. Our results encourage the use of traction as a concept in management of developmental dislocation of the hip.
9只未成年猪（年龄：8 - 12周）先承受相当于体重10%、30%和50%的纵向牵引，随后承受相当于体重10%和30%的悬吊牵引。通过激光多普勒血流探头监测股骨头的微循环，通过超声血管周围渡越时间血流探头监测旋股外侧动脉内的大循环。将每个牵引期的血流变化与之前的静息期进行比较，并以百分比表示。尽管未检测到显著差异，但在任何类型的纵向和悬吊牵引过程中，均观察到髋关节微循环和大循环有改善的趋势。我们的研究结果鼓励将牵引作为髋关节发育性脱位治疗的一种理念。
