当脚承受重量时，足底的压力由跟骨和所有五个跖骨的头分担。Abramson（'27）、Elftman（'34）、Morton（'35）和Jones（'41）已经证明，这些支承点中的每一个都承受相当确定的载荷比例。在踝关节和脚底支撑区域之间的结构中发生了什么尚不清楚。通常，载荷的弯曲效应倾向于使纵向足弓变平，从而产生沿着足背沿着压缩关节并拉紧足底韧带的应力。这些内力的分布，以及它们与足部解剖结构的关系一直是人们猜测的话题。详细的解释，无论多么精明，只要缺乏支持它们的事实，就应该被认为是试探性的。需要更明确回答的一个问题是，考虑有多少力作用在单个足骨和内部点上。在简单的静态载荷条件下，已在尸体足上测量了分离骨之间的压缩力。这些数据与负重力学和足部结构相关。方法
When the foot bears weight, the pressure under the sole is shared by the calcaneus and the heads of all five metatarsals. Abramson ( '27), Elftman ( '34), Morton ( '35) and Jones ( '41) have shown that each of these points of support bears a fairly definite proportion of the load. What takes place in the structures which lie between the ankle and the areas of support a t the base of the foot is not clear. I n general, the bending effect of the load tends to flatten the longitudinal arch producing stresses that compress the joints along the dorsum of the foot and tense the plantar ligaments. The distribution of these internal forces, and their relationship to the anatomy of the foot have long been topics of speculation. Detailed interpretations, however shrewd, should be considered tentative as long as the facts to support them are lacking. One question which requires a more definite answer is the consideration of how much force is brought to bear on individual foot bones a t internal points. Under simple conditions of static loading the compression forces between separate bones have been measured in cadaver feet. These data have been correlated with the mechanics of weight-bearing, and with the structure of the foot. METHODS
