To investigate whether, when inserting a syndesmotic screw, the foot position effects the range of motion in dorsal extention, 16 osteoligamentous lower-leg preparations were studied. The specimens were placed in a test frame where a constant dorsal extention force could be applied to the foot. The dorsal extention capacity was recorded with a syndesmotic screw inserted by a standardized technique in various plantar flexion positions. The dorsal extension capacity decreased by an average of 0.1 degree for every degree of increase in plantar flexion when the screw was being inserted. There was a correlation between a large decrease in range of motion and a limited dorsal extension capacity to start with. No correlation could be found between a large decrease in range of motion and a large difference in width between the anterior and posterior edges of the talar trochlea. The results suggest that the foot should be in maximal dorsal extension when a syndesmotic screw is inserted in order to decrease the risk of stiffness.
为了研究在插入下胫腓联合螺钉时，足部位置是否会影响背伸活动范围，对16个小腿骨韧带标本进行了研究。将标本置于测试框架中，在该框架上可以对足部施加恒定的背伸力。通过标准化技术在不同跖屈位置插入下胫腓联合螺钉时，记录背伸能力。插入螺钉时，跖屈每增加1度，背伸能力平均下降0.1度。活动范围大幅减小与一开始有限的背伸能力之间存在相关性。活动范围大幅减小与距骨滑车前后边缘宽度的巨大差异之间未发现相关性。结果表明，插入下胫腓联合螺钉时，足部应处于最大背伸位，以降低僵硬风险。
