Lengthening the lateral column of the foot has been shown to correct flatfoot deformity. In adults, however, lengthening leads to calcaneocuboid arthritis. Lateral column lengthening with calcaneocuboid fusion, which lengthens the lateral column of the foot and prevents calcaneocuboid arthritis, was investigated in a cadaver model to determine the remaining range of motion in the talonavicular and subtalar joints. Inversion/eversion motion was produced by tendon pulls and the range of motion was measured in three dimensions using a magnetic space tracker. After lateral column lengthening with calcaneocuboid fusion, 48% of talonavicular and 70% of subtalar joint range of motion were preserved. Analysis of the inversion and eversion ranges of motion suggests that the lengthening fusion limits eversion more than inversion. These findings demonstrate the need for clinical investigation of this procedure, which could preserve motion in the talonavicular and subtalar joints, correct deformity, and obviate calcaneocuboid arthritis.
延长足外侧柱已被证明可矫正扁平足畸形。然而，在成年人中，延长会导致跟骰关节炎。在一个尸体模型中研究了跟骰融合的外侧柱延长术，该手术可延长足外侧柱并预防跟骰关节炎，以确定距舟关节和距下关节的剩余活动范围。通过肌腱牵拉产生内翻/外翻运动，并使用磁性空间跟踪器在三个维度上测量运动范围。跟骰融合外侧柱延长术后，距舟关节活动范围保留了48%，距下关节活动范围保留了70%。对内外翻运动范围的分析表明，延长融合对外翻的限制大于对内翻的限制。这些发现表明需要对该手术进行临床研究，该手术可以保留距舟关节和距下关节的活动，矫正畸形，并避免跟骰关节炎。
