X-ray and cineradiography measurements were used to compare the suspension effect and stability of a TSB trans-tibial prosthesis with an Icelandic Roll-On Silicone Socket (ICEROSS) system to that of a PTB trans-tibial prosthesis. The suspension effect was measured by the distance between the tibia and the socket in both suspension position and weight-bearing position in both type of prostheses. The suspension effect of the TSB prosthesis (2.53 +/- 0.90 cm) was superior to that of the PTB prosthesis (3.60 +/- 0.56 cm) (p < 0.05) by x-ray measurement. The suspension effect of the TSB prosthesis (0.1, 0.4, 0.72 cm) was superior to that of the PTB prosthesis (0.3, 0.48, 1.03 cm) (p < 0.01, p < 0.05) by cineradiographic measurement. The stability was measured as the angle between the axis of the tibia and the prosthesis at the time of heel contact and toe off. The angle change of the TSB prosthesis was statistically smaller than that of the PTB prosthesis.
采用X射线和动态放射摄影测量法，比较了带冰岛式套入式硅胶接受腔（ICEROSS）系统的全接触式髌韧带承重（TSB）小腿假肢与髌韧带承重（PTB）小腿假肢的悬吊效果和稳定性。通过测量两种假肢在悬吊位和承重位时胫骨与接受腔之间的距离来评估悬吊效果。经X射线测量，TSB假肢的悬吊效果（2.53±0.90厘米）优于PTB假肢（3.60±0.56厘米）（p<0.05）。经动态放射摄影测量，TSB假肢的悬吊效果（0.1、0.4、0.72厘米）优于PTB假肢（0.3、0.48、1.03厘米）（p<0.01，p<0.05）。通过测量足跟触地和足趾离地时胫骨轴线与假肢之间的角度来评估稳定性。TSB假肢的角度变化在统计学上小于PTB假肢。
