We defined the relative contributions of six ligaments in stabilizing the arch of the foot: plantar aponeurosis, long-short plantar ligaments, plantar calcaneonavicular ligament (spring ligament), medial talocalcaneal ligament, talocalcaneal interosseous ligament, and tibionavicular portion of the deltoid ligament. Nineteen fresh-frozen human foot specimens were used. A load of 445 N was applied axially to simulate standing-at-ease posture. Three-dimensional positions of tarsal bones before and after ligament sectioning were determined with the use of a magnetic tracking device. The motions were presented in the form of screw axis displacements, quantitating rotation, and axis of rotation orientation. After sectioning one structure, the arch did not collapse on any specimen and there was no obvious change by visual inspection. There were, however, measurable changes in tarsal bone position. Metatarsal-to-talus total rotation difference was greatest with spring ligament and deltoid ligament sectioning, with an average of 2.1 degrees +/- 1.7 degrees and 2.0 degrees +/- 0.2 degree difference, respectively. Calcaneus-to-talus rotation difference was greatest with talocalcaneal interosseous ligament sectioning, with an average of 1.7 degrees +/- 1.5 degrees. The spring ligament, deltoid ligament, and talocalcaneal interosseous ligament were most important for arch stability.
足底腱膜、长短足底韧带、跟舟足底韧带（弹簧韧带）、内侧距跟韧带、距跟骨间韧带以及三角韧带的胫舟部分。使用了19个新鲜冷冻的人体足部标本。轴向施加445N的载荷以模拟自在站立姿势。在韧带切断前后，使用磁跟踪装置确定跗骨的三维位置。运动以螺旋轴位移的形式呈现，量化旋转和旋转轴方向。切断一个结构后，任何标本的足弓都没有塌陷，肉眼检查也没有明显变化。然而，跗骨位置有可测量的变化。切断弹簧韧带和三角韧带时，跖骨与距骨的总旋转差异最大，平均差异分别为2.1度±1.7度和2.0度±0.2度。切断距跟骨间韧带时，跟骨与距骨的旋转差异最大，平均为1.7度±1.5度。弹簧韧带、三角韧带和距跟骨间韧带对足弓稳定性最为重要。
